交换机
惠普
HP ProCurve Switch 8212zl是惠普“绿色”交换机的代表,其是一款具备高性能和高可用的机箱式交换机平台,支持统一的核心到边缘适应性网络解决方案;其平台与软件高可用性的特性,可以确保系统持续运行并提高网络生产效率。
在降低能耗方面,HP ProCurve使用了各种节能技术,如LLDP-MED可变风扇等;尽可能采用基于机箱的交换机;在不工作的时候关闭PoE;根据实际应用选择电源和UPS。
此外,HP ProCurve系列几乎所有产品都提供终身保修、软件升级、技术支持和第二工作日替换等免费服务,这些对于减少碳排放和节约成本起到了至关重要的作用,因为产品的使用寿命会因终身保修而延长,用户就不用频繁地更换设备,也不用再处理老设备带来的电子废料。
迈普
为了实现交换机的绿色节能,迈普应用了多种技术优化产品设计。首先,通过采用高性能的交错式PFC控制技术提高交换机电源模块的电源转换效率,这将传统的电源转换效率从70%~80%提高到了85%。
其次,全面应用了以太板卡的以太端口休眠功能,对于不用的端口或者没有数据传输的端口大幅降低了接口芯片的功耗,对于GE电口的8根网线全部传输数据时的高功耗也实现了有效的降低,当使用闲置端口休眠或不使用时,能够降低40%左右的功耗。同时,采用高密度的业务板卡降低功耗,通过提高板卡的密度来降低单端口的功耗。
此外,大容量的主机、灵活的业务板卡升级功能设计延长了设备的使用寿命;优化的整机结构设计,加强了整机的散热性能,竖插槽的设计则利用了自然散热的原理大幅降低了散热设备的功耗。
极进
极进网络的BlackDiamond 8810是一款标准的万兆核心交换机,作为服务网络骨干或数据中心的核心交换机,其工作时间一般都是7×24小时,因此低能耗设计带来的电力节省就相当可观了。该设备可以安装最多6个电源模块,每个电源模块功率为1200W,用户可以根据需求灵活配置电源模块数量,且所有的板卡均采用低能耗设计。

存储
UIT
UIT绿色存储的核心是设计运行温度更低的处理器和更有效率的系统,生产更低能耗的存储系统或组件,降低产品所产生的二氧化碳,而其所应用的主要技术是MAID(Massive Arrays of Idle Disks,大规模非活动磁盘阵列存储)――在正常状态下所有的磁带都放置在磁带库的槽位中,需要某盘磁带时才将它放在磁带机中,然后进行数据读写。而在大部分时间,大多数磁带是处在非工作状态的。
UIT BM3800B是UIT推出的一款具有MAID绿色存储功能的光纤通道存储设备,其在绿色节能方面具有以下几个重要的功能和特点:磁盘或磁盘RAID组可以在没有读写访问时依据策略下电;下电磁盘自动按照策略进行故障检查;磁盘在下电以后,一旦有读写请求,磁盘自动上电,RAID组可重新提供正常访问;降低能耗,电能节约可达到30%;减少环境和管理成本;更长的磁盘使用寿命。
日立
日立认为,存储基础架构对能源的消耗是与磁盘数直接挂钩的,而非储存的数据量,所以容量的密度越大就意味着能耗效率越高,因此利用虚拟化来部署分层存储和实施通用管理架构能够大大提高资源的利用率。
日立的USP产品不仅配有基于控制器的虚拟化引擎,还可以将控制器与存储介质相分离,允许企业将其直连式存储系统、网络附加式存储系统和存储区域网络都整合到一个存储平台中,使用户可以在短短几秒钟内将存储空间分配(或解除分配)给某个应用。
此外,日立还基于USP V平台在企业级虚拟层实现了Thin Provisioning(动态精细化预配置)功能:USP V与Hitachi Dynamic Provisioning(动态与配置)软件的结合使用户能够在一个整合的解决方案中同时获得外部存储虚拟化的好处以及由Thin Provisioning带来的电力和冷却成本方面的优势。
飞康
飞康在两年前就与COPAN合作,将MAID(大规模非活动磁盘阵列)技术导入了VTL,这就节省了设备闲置时所消耗的电能;其新一代VTL具备重复数据删除技术,可以帮助用户节省大量备份所需的磁盘空间;IPStor具备的存储资源按需分配(Thin Provisioning)功能,更将存储资源的利用率从低于30%提高到80%以上,使用户现有的存储投资能得以继续利用。
此外,飞康VTL企业版可以扩展远程复制功能,用户可以利用WAN广域网络将备份数据复制到远程,并实现异地灾备。在执行远程复制时,本地和远程的VTL会自动比对单一存储区内有没有相同数据,只有不重复的数据才会被复制并传输到远程,这可以减少95%的网络带宽使用率。
SEPATON
SEPATON实现“绿色”存储的关键技术手段主要是重复数据删除、自动精简配置及数据压缩等,其中重复数据删除和自动精简配置最能大幅度削减能源消耗。SEPATON的DeltaStor软件利用其“内容已知(ContentAware)”架构,以字节为单位进行全面的数据比较,以确保数据的完整性,并且在主要数据传输路径之外执行重复数据删除,使其性能不受影响。Deltastor软件能提供多节点可扩展性,并可以处理PB级数据。
据悉,利用DeltaStor技术后,存储数据占用的空间相比以前为1∶50,这样就节约了高达62%的数据中心空间,以及85%的能源和散热成本。同时,采用ContentAware架构,SEPATON为日后扩大容量、提高性能打下了基础,在面临数据中心需求不断变化的情况下,可以有效地保护用户已有的投资,避免造成浪费。
昆腾
据悉,Quantum DXi系列磁盘备份系统能够在整个企业中扩大重复数据删除技术的优势,重复数据删除技术可以使磁盘需求降低90%甚至更多。借助该技术还能够实现快速备份和还原,并减少了对介质的使用,对电源和冷却的要求也更低,整体数据保护和保留成本还相应降低。
Quantum DXi7500是一款高可用性企业磁盘备份系统,可以作为磁盘备份系统运行,在这种情况下,利用传统的虚拟磁带库接口就能提供更高的吞吐量,同时也可以作为启用了重复数据删除功能的磁盘备份和远程复制系统。
此外,DXi7500还拥有直接磁带创建功能,让用户能够将存储在磁盘上的备份数据自动迁移到磁带上以进行更长期的保留,而这一操作是在后台进行的,因此对用户的介质服务器或备份SAN没有任何影响。

0 Introduction
Mobile devices have gained increasingly popularity due to its portability nature. People use these small mobile devices to manage personal information, do simple work with poor processing requirements, or remotely control PCs and computerized appliances [1]. Nowadays, the use of mobile devices has penetrated into the domains of education, business, military, etc.
Compared with traditional desktop computers, mobile devices have many limitations in terms of 1) small-sized display with poor resolution, few colors, and different width/height ratio from the normal setup; 2) constrained CPU processing and memory capacities; 3) slow connection with fluctuated bandwidth; and 4) unfriendly user input facilities (ordinarily used keyboard and handwriting demand lots of screen space, incurring quite inaccurate results) [2,3].
Due to these large differences, the classic desktop solutions cannot directly be adopted to mobile user interface design. [4,5] made a good summary of the main challenges in mobile human-computer interaction. In this study, we are particularly concerned about information presentation on mobile devices. After a brief description of the major challenges upon mobile information presentation, we overview some latest development of information presentation techniques for mobile devices through diverse channels including visual, audio, and tactile channels.
1 Main Challenges for Mobile Information Presentation
The inherent characteristics of mobile devices lead to the following design considerations for mobile information presentation.
-Mobile devices have limited interaction facilities. Constrained by small screen size, poor-quality sound output, and tiny keypad, no-handed or simple interaction operations during information presentation are always preferred. In line with human's perceptual and cognitive ``top-down" behavior, outputting the most useful or high-leveled information and then letting users decide whether or not to retrieve details further constitute a good strategy for information output [5].
-Mobile devices are portable. Users carrying mobile devices can enter multiple and dynamic contexts embedded with various sensors and networks. These unreliable or patchy sensors may also bring incomplete and varying context information. It would be desirable to permit users to configure output to their needs and preferences (e.g., content precision, text size, brightness, etc.) to tailor to the user's current environment [4,5].
-Mobile users have poor focus. User focus is a massive issue, as in a mobile environment, frequency of interruptions is likely to be much higher than on desktops. The information presentation process shall be easily stopped, started, and resumed with little or no effort to enable to switch user’s attention from the device to his/her activity itself. Besides, a multi-modality option via sound or tactile channel can be adopted to prevent user's too much attention in reading the content on mobile devices [5].
-Mobile devices have a widespread population. Simple user interface should be designed, because users often don't have any formal training in their technologies. Besides, it must allow for personalization, providing users the ability to change settings themselves. Also, the information presentation should be visually pleasing and fun as well as usable to offer enjoyment [5].
Among the challenges, one prototypical big problem facing mobile device user interface designers is how to effectively and efficiently present a large amount of information contents on tiny screens. The most common strategy on desktop computers with relatively large screens is using scrollable viewports that reveal a subpart of the data [6]. However, this strategy can hardly be applied to mobile devices, since people often use mobile devices on-the-go, making it difficult for them to drag scroll bars. In addition, as scrollable viewports present only a subpart of data while hiding most of the data, they provide very limited contextual information to users [6]. Therefore, many human-interface researchers are trying new methods to enable and enhance information presentation on mobile devices, utilizing visual, audio, and/or tactile channels. We review these great efforts in the following sections.
2 Information Presentation via Visual Channel
The ways to visually present contents vary from the types of contents (e.g., Web pages, texts, images, maps, or structured data, etc.) to be displayed [2].
2.1 Web Page Presentation
Mobile Web search receives great attention nowadays. Web contents, mostly designed for desktop computers, are badly suited for mobile devices [7,8]. Currently, the majority of commercially available mobile web browsers use single-column viewing mode to avoid horizontal scroll. But this approach tends to have much more vertical scrolls and destroys the layout of original view.
Based on small- and large-scaled user studies, [9,10] provided a list of general principles for Web page display. They are: 1) developing phone-based applications to enable direct and simple access to focused valuable contents; 2) trimming the page-to-page navigation down to a minimum; 3) providing more rather than less information for each search result; 4) using simple hierarchies which are similar to the phone menus that users are already familiar with; 5) adapting for vertical scrolling or reducing the amount of vertical scrolling by simplifying the text to be displayed; 6) reducing the number of users' keystrokes; 7) providing a quick way for users to know whether a search result points to a conventional HTML page or a small screened optimized page; 8) pre-processing conventional pages for better usability in small screen contexts; and 9) combining theoretical and empirical evaluation to gain further insights [9].
In order to deliver adaptive Web contents to mobile devices, researchers attempt to re-author web pages by means of presentation optimization, semantic conversion, or zooming, etc., which can be done at server side, intermediate side, or client side [11].
1) Re-authoring Web Pages at Server Sides
Server-side adaptation provides Web page authors maximum control over content delivery to mobile devices [11]. [12] reported a system which used the W3C's Document Object Model (DOM) API to generate an XML tree-like structure, as well as the Extensible Style Sheet Language Transformations (XSLT) to generate Wireless Markup Language (WML) and HTML content for display on mobile devices. This system could also adapt to users' dynamic contexts. [13] presented another system which could adapt multimedia Web documents to optimally match the capabilities of the client's mobile devices. In a scheme called InfoPyramid, content items on a Web page were transcoded into multiple resolution and modality versions, so that they could be rendered on different devices. Customers could select the best parameters from the InfoPyramids to meet the resource constraints of the client's devices while still guarantee the most “value” [13].
2) Re-authoring Web Pages at Intermediate Sides
Proxies typically apply intermediate adaptation [11]. Today, many of web page visualization efforts fall into this category. Without changing the layout of original web pages, [14] reduced the size of images which were larger than that of mobile screens and removed media which mobile devices did not support. [7] described a scaled-down version to fit the mobile devices screen. Images embedded in a web page and the Internet address bar were removed; and the font size of textual contents was adjusted by the user [7]. The focus+context visualization was also employed in the display of mobile Web. Users could choose what they are interested in with a large font size, while other information in the surrounding area can be displayed in a reduced font size [7].
Currently, Web page transcoding is a widely used approach. [7,15] applied a DOM tree generation and navigation technique for mobile Web interface. Content blocks with extracted labels and their relationships in a web page were automatically identified in the DOM tree. A Web page on mobile devices was represented as a hierarchical structure of content blocks. At the beginning, the highest level of a generated DOM tree was given to the user. If the user was interested in some sub-topics, s/he could click the node to expand it to the next level. Some researchers proposed to do a Web-page semantic segmentation based on a DOM tree [16,17], because they think DOM tree is in disorder in semantic sense. [17] applied type analysis based on the refined typing system to generate blocks.
[18] considered to split a Web page's structure into smaller but logically related units. A two-level hierarchy was used with a thumbnail representation at the top level to provide a global view and an index to a set of subpages at the bottom level for detailed information. [19] introduced heuristics for structure-aware Web transcoding which considered a Web page's structure and the relative importance of its components. [8] proposed to display a web page as a thumbnail view, but preserving the original page layout, so that users could identify the overall page structure and recognize pages they previously viewed. This method provides readable text fragments which allow users to disambiguate the desired information from similar looking areas. When users zoom in for the interesting information, the original unabbreviated version of the page will be shown. During the zooming operation, the thumbnail view and the detail views look similar, so that users can recognize the thumbnail view corresponding to the detail view [8]. [20,21] proposed to show Web pages in a modified original layout, where texts and images on a Web page are scaled to fit the display width. First, the size of the text relative to the rest of the page contents is modified and the browser viewport is limited. Second, a scaled down version of the whole page is overlaid with an indication of the current viewport at the top. Web contents can also be taken out of table cells and shown one after another in the order specified in markup files.
3) Re-authoring Web Pages at Client Sides
A client device can use style sheets to format contents in a browser [11]. For instance, the font size of textual contents can be adjusted by users [7]. Together with the above intermediate-side approaches, by storing user's operations with the DOM tree in a profile, the system could automatically generate a DOM-tree with branches expanded or hidden according to users' interests [7].
Along with the popularity of mobile Web search, Google's PDA mobile Web search interface differs from its XHTML interface in the following three main aspects [22]: 1) it only offers Web and Image searches; 2) it displays the same snippet as desktop search, and 3) no trancoding is performed before displaying a clicked link. In [23], the mobile search interface provided automatic search result categories to present the user with an overview of the result set. In addition, the interface utilized a focus+context method to help present the result list. Researchers have also proposed many novel approaches to mobile search by considering context information. [24] provided a novel interface which is well-adapted to the need of mobile users. They provided historical query and result selection data for users to navigate through on an interactive map-based interface.
Mobile devices and mobile Internet bring extremely challenging to mobile search. In order to understanding the needs of mobile search, many researchers [22,25,26] studied mobile search patterns. [25] conducted a large-scale study on English mobile queries from the US, Europe, and Asia, which were submitted from mobile devices using Yahoo!. They found the following characteristics of mobile queries. 1) Personal entertainment is the most popular queries, and users are searching for a broad category personal entertainment. 2) Mobile query pattern is still dynamic. 3) There exist meaningful variations in the regional query pattern in terms of the quantitative statistics. 4) There are interesting differences among users query of various search applications in terms of their topical interests of their queries. [25,26] examined wireless search patterns for a major carrier in the United States by analyzing Google search queries. Compared with their study in 2005, they found some interesting trends [26]. 1) Users type faster. 2) More queries had at least one click. 3) There are more explorations within one session. 4) Mobile queries are becoming less homogeneous. 5) There are more high-end devices. 6) The percentage ofqueries is increasing.
Compared with queries in desktop, research in [22] showed the diversity of queries in mobile environments was far less. This might be due to the enormous amount of efforts (in terms of time and key presses) needed for users to enter query terms, so that each session on mobile devices had significantly fewer queries than sessions initiated on the desktop [22].
Users for the most part tended to search similar contents as desktop queries, and the percentage ofqueries was vastly larger [22]. [22] also analyzed Google's XHTML search and Google's PDA search histories related to how and why typical users use mobile Web search, in order to better understand mobile search users. Google's PDA interface is similar to Google's XHTML interface [22], but it has the following three main differences. 1) The PDA interface only offers Web and Image searches; 2) The PDA interface displays the same snippet as desktop search. 3) No trancoding is performed before displaying a clicked link. In [23], the mobile search interface provided automatic search result categories to present the user with an overview of the result set. In addition, the interface utilized a focus+context method to help present the result list.
Researchers also have proposed many novel approaches to mobile search by considering context information. [27] proposed a query prediction system for helping enter a query. The system redefined the prediction dictionary after considering contextual signals, such as knowledge of the application being used and the location of the user. Combining context features, [24] provided a novel interface which is well-adapted to the need of mobile users. They provides historical query and result selection data for users to navigate through on an interactive map-based interface [24].
2.2 Text (Lengthy Document) Presentation
Two popular ways to view lengthy documents on small screens in the literature are Rapid Serial Visual Presentation (RSVP) and Leading Format Presentation (LFP) [28,29]. 1) RSVP presents one or more text words at a time at a fixed location on the screen [30]. Two variants of RSVP, namely, Adaptive RSVP and Sonified RSVP, were detailed in [31,32]. Adaptive RSVP adjusts each text chunk exposure time with respect to content (e.g., the number of characters and words to be exposed) as well as to context (e.g., the result of content adaptation, the word frequencies of the words in the chunk, and the position of the chunk in sentence being exposed). Sonified RSVP plays appropriate sound when a certain text chunk is displayed. 2) LFP method scrolls the text in one line horizontally or vertically across the screen [29,30,31]. Considering that sentence boundary is important in reading, a sentence-oriented presentation manner was developed for a small window, which presented complete sentences one at a time [30].
In general, sentences can be read more accurately and more natural in the RSVP format than in the LFP format [32,33]. This is because when human's eyes process information during fixed gazes, it is more comfortable that the text moved successively rather than continuously. However, the experiments of [34] showed that comprehension for smooth scrolling times square was at least as high as that for RSVP at presentation rates ranging from 100 to 300 words per minute. [35] compared RSVP with three-line and ten-line LFP presentation method, and found out that readers favored the slower speed, and were equally satisfied with the three methods. But [35] supported the use of RSVP, because even with no experience with RSVP reading, participants were able to read just as accurately and were just as satisfied as the other two, and more participants were comfortable at faster speeds with RSVP than the others.
2.3 Image Presentation
To visualize data-intensive images on mobile devices, an intuitive solution is to compress and transcode images to reduce data transmission and processing. JPEG 2000 detailed a progressive transmission mechanism which allowed images to be reconstructed by different pixel accuracy or spatial resolution and be delivered to different target devices of different capabilities [36]. [37] introduced a non-uniform resolution presentation method, in which resolution was the highest at the fovea but falls off away from the fovea. [38] classified images according to image type and purpose, and transcoded images to adapt to the unique characteristics of the devices with a wide range of communication, processing, storage, and display capabilities, thus improving the delivery.
Besides treating an image as a whole, [39,40,41] proposed to separate region-of-interest and deliver the most important region to the small screen according to the human's attention model. They used RSVP presentation technique to simulate the attention shifting process, and noticed that there was an important psycho physiological activity - visual attention shifting. Image browsing on small devices could be improved by simulating the fixation and shifting process in a way similar to RSVP. An image was decomposed into a set of regions which were displayed serially, each for a brief period of time. [39] further described a generic and extensible image attention model based on three attributes (i.e., region of interest, attention value, and minimal perceptible size) associated with each attention object. [40,41] tried to find an optimal image browsing path based on the image attention model to simulate the human browsing behavior. [42] developed a level-of-detail technique to adapt tree and/or cluster images on mobile devices. For tree images designed to visualize a hierarchy of categories, small rectangles in deep layers can be merged into a single larger rectangle. When users tap a rectangle, the tapped one will be enlarged to occupy the whole screen. For cluster images, details of the cluster image including the spheres in the user groups are neglected, when the user is looking at an overview of the visual presentation.
2.4 Map Presentation
Maps play an important role in mobile location-based services. However, they are often too large to be fully displayed on mobile device screens [2]. To this end, [43] used 3D arrows to point towards the objects and by the side of the arrows, the information about distance and name of point objects was provided with text. The 3D arrows were semi-transparent for comfortable visual. City Lights [44] was another attempt to provide a lot of types of off-screen objects information in that direction. It placed along each of border of a window.“Halo” [45] and zooming [46] are two popular methods used in map navigation task, where zooming allows the user to continuously move in and out of level of detail by using distance to the plane, and “Halo” represented off-screen locations as abstract “streetlamps” with their lights on the map. The map was overlaid with translucent arcs, indicating the location of off-screen places. Each arc was part of a circular ring that surrounds one of the off-screen locations. The arcs on the map allowed viewers to recognize the missing off-screen parts, and let viewers understand its position in space well enough to know the location of the off-screen targets. [46] compared user performance between “Halo” and zooming methods. Their work shows that ``Halo" is helpful for low numbers of distracting targets, and zooming helps independently of the number of distracters. They hence suggest that the interface can combine the effect of these two methods, so that the joint performance keeps the desirable feature of the individual performance.
2.5 3-Dimensional Object Presentation
To visualize 3D model on mobile devices, Virtual Reality Modeling Language (VRML) and Extensible 3D(X3D) allow a content developer to re-use a large collection of existing Web-Based 3D worlds in the mobile context and develop content for different platforms with the same tools [47]. For location-aware presentation of VRML contents on mobile devices, the user interface was divided into two parts: an upper area where the actual 3D world was visualized and a lower area providing status information and tools for users to navigate the 3D world, setting the system and moving the viewpoint [47]. [48,49] used an integrated camera to visually track physical mobile interaction. [48] provided a 3D interface which can track the movement of a target by analyzing the video stream of the handheld computer camera. The position of the target can directly be inferred from the color-codes that are printed on it [48]. [49] proposed an interaction technique that uses the position of the mobile device in relation to a tracked point as input, as it is believed that the possibility of using mixed interaction spaces is what distinguishes camera-based interaction from other types of sensor-based interaction on mobile devices.
2.6 Calendar Presentation
Showed an interesting fisheye calendar interface called DataLens on PDAs. On the interface[50,51], users could first have an overview of a large time period with a graphical representation of each day's activities. Then, users could tap on any day to expand the area representing that day and reveal the list of appointments in context [51]. The “semantic zooming” approach used in DataLens was utilized to visually represent objects differently depending on how much space is available for displaying. The graphical views were scaled to fit the available space, while the textual views used a constant-sized font, and the text was clipped to fit in the available space [51]. On the DataLens, four views (tiny view, agenda view, full day view, and appointment detail) are available.
There were also some work to explore the visualization of quantitative information on mobile devices. [52] used bars with colors to present negative and positive values, instead of splitting the scarce screen space into two smaller areas.
2.7 Database Presentation
Current approaches for desktop-based database interfaces fall into two categories, i.e., visual interfaces and keyword-based interfaces [53]. In the visual database interface category, visual query specification interfaces (e.g., QBE [54] and XQBE [55]) and forms-based query interfaces (e.g., GRIDS system [56] and FoXQ system [57]) have both received considerable attentions. In the keyword-based interface category, designers equip database systems with an IR-style keyword-based search interface and the systems automatically discover and display the hidden semantic structures that the keyword query carries [53].
However, for mobile devices with a much smaller display, users may feel too heavy and even unreadable when presented with a complete query result satisfying a query condition at one time, calling for new database presentation strategies in the mobile domain. [58] thus conducted a study on how to selectively and dynamically present database contents on small screens. Five selection strategies, namely, Context-based Selection, Context-Cluster-based Selection, Attribute-Cluster-based Selection, Frequency-Based Selection, and Recent Frequency-Based Selection, were designed in order to choose the most potentially useful attributes to be displayed on the screen. The two well-developed methods, i.e., leading format and serializing format for dynamically displaying database query results on small screens were employed. The five methods on both synthetic data and real data were evaluated. The context-based and context-cluster-based strategies were superior over the rest according to the average selection accuracy, while the context-based approach also cost the least selection time. The majority of the users in the experiment found the serial display manner more comfortable and helpful than the leading display manner to get their wanted information from the screen.
further designed a graphical database interface for mobile devices. In this method[59], as soon as a connection was made, the relations in the database were displayed on their interface. Initially, only “top-level” relations were shown, and for the sake of conserving screen space, a nested relation structure was imposed on non-nested database systems. On the interface, users could select any number of relations, and display all the possible join paths between them. The resulting join was displayed on an auxiliary screen, which showed the actual SQL query and the actual answer set for that query [59].
3 Information Presentation via Audio Channel
Given the hard-handling and limited screens, it is beneficial to make use of the speech channel of mobile devices. [60] illustrated a comprehensive list of reasons for audio output. First, voice is portrayed as the most naturalistic way to interact with a system, so speech interface is more natural for interaction. Second, speech interface helps increase interaction efficiency, because speech is faster than any other common communication method like typing and writing. Third, voice interaction avoids “hand-busy” and “eye-busy” operations which happen to the visual interface. Fourth, people tend to think that telephony network is often more trustworthiness than Web. Finally, speech interface can serve as a good input manner, where speech recognition avoids password input [60]. Ease-of-use and the speed of interaction are the two most important requirements for voice interface, and voice interface must be an integral part of the whole user interface of the device, but should not be overused due to the miss-recognition [61].
evaluated reading performance on mobile devices for both a handheld visual display and a speech-synthesis audio display. They found that the audio interface allowed users to better navigate their environment. These findings suggest that users may benefit from an audio display[62]. designed a multi-lingual speaker-dependent voice dialing user interface, which could support speech recognition and speech synthesis[61]. Users need not train the voice tag, and the interface system can generate the tag automatically. [63] offered a speech interface model, where users can use a single personalized speech interface to access all services and applications. This approach decreased the misunderstanding and miss-recognition of multiple appliances.
4 Information Presentation via Tactile Channel
Apart from visual and audio channels, tactile sensation can also be explored for information presentation. The experiments done in [64] showed that a touch-based user interface can provide the elderly an easy-to-learn user interface paradigm. In addition, by tactile feedback, we can reduce possible mobile interaction mistakes, since audio feedback is difficult to apply when the environment is noisy, and visual feedback is also difficult as users have to pay much attention to others and the screen is small. In face, users can feel the vibration with their fingers as they press the screen [65]. [66] did text entry experiments and showed that users with tactile user interface could enter significantly more text, made fewer errors, and corrected more errors they did make.
used paper metaphor to design the switching of scrolling and editing operations[67], where a touch sensor is attached to a PDA. In map or Web browser, when a user does not touch sensor, the screen scrolls according to the movement of the pen when dragging, and when touching, the screen does not scroll and edit while dragging. In the photograph browser, when the user does not touch the sensor, the screen also scrolls the photograph, but when touching, if dragging the pen upward, the photograph is zoomed in; and if downward, the photograph is zoomed out. Dragging the pen left to right invokes clockwise rotation, and right to left invokes counter clockwise rotation [67].
Sometimes, it is necessary to switch among different user interaction modes on mobile devices. [68] outlined five switching ways between ink and gesture modes for a pen interface. Those mode switching techniques are “Pressing Barrel Button”, “Press and Hold”, “Using Non-Preferred Hand”, “Pressure-Based Mode Switching” and “Using the Eraser End of a Pen” [68].
5 Others
Except the above approaches, researches tried some novel methods to help mobile interface design. Considering that users often repeat certain tasks when they use mobile phone, [26] used shortcuts for these repetitive tasks. Some methods of producing shortcuts are evaluated, such as last performed, most frequent, C4.5 decision tree, Native-Bayes Base, and etc. They illustrated that the hybrid approach combining frequency and Native-Bayes approaches exhibits potentials for mobile device user interface.
6 Conclusion
In this survey paper, we gave an overview of recently developed techniques for mobile information presentation through the visual, audio, and tactile channels of mobile devices. The multiple presentation strategies compromise with each other to contribute the easy and convenient use of mobile devices.

第6届手机国际展会于3月26-28日在北京举行。此次展会以“亚洲和手机通信”为主题,吸引了众多手机产业的中外相关企业参展,其中,日本厂商多达50家,村田制作所(muRata)就是其中之一。该公司主要展示的是泛网通信和汽车电子产品。另外,最令人注目的是具有鲜明特色的、集其优势产品与技术于一身的产物,即会骑自行车的机器人――村田顽童。
村田制作所的工程师演示了村田顽童的独特技艺:以超低速在平衡木上行驶而不会倒下,平衡木的宽度与村田顽童的车轮相同。它不倒的原因在于配置在鞍形支架下的陀螺传感器,只要感觉到一丝晃动,就会检测出车体的倾斜,一旦检测出自行车的倾斜,即通过旋转村田顽童心中的大辐板,产生消除倾斜的力。如此反复,以调节平衡。通过收发命令的蓝牙模块、用于电眼照相机的透光性陶瓷透镜、电池、电源模块、电容器、电磁干扰滤波器等部件,以及该公司的控制技术、电路设计方法、软件工具等实现了这种能力。所以,村田顽童是该公司优势技术与产品的整和产物。其中,最为突出的就是陶瓷电容器、陀螺传感器、噪声消除元器件和蓝牙模块。目前,村田制作所的陶瓷电容器已经占据35%的全球市场份额,噪声消除元器件也有30%的市场占有率。此外,其蓝牙模块也在手机中得到了广泛的应用,并且开始计划向在过去两年里创造了便携式音频播放器市场神话的iPod方向发展。
村田制作所还以“车体控制、安全、舒适、信息化”为切入点,重点介绍了其在汽车市场上的综合应对能力以及产品和技术,特别是传感器,该公司将主要面向汽车间距感测、气囊等安全系统力推新品。同时,车身控制和导航应用也是其传感器的重点发展方向。该公司的振动陀螺传感器采用压电陶瓷制造,并融合了最新的MEMS技术,通过独特的振荡子结构,实现了较强的抗振和抗冲击能力,结合其稳定的温度特性,可为汽车导航系统的高性能化提供保证。
另外,实现泛网通信也是村田制作所一直追求的目标,特别是以手机、DVD录像机、笔记本电脑等信息家电为中心,集中展示了他们的相关产品和技术。该公司在移动通信用滤波器的小型化方面具有一定的特色。它们的GIGAFIL介质滤波器与初期型号产品相比,实现了1/2000的小型化。而为将同样的功能从介质滤波器转换到表面波(SAW)滤波器而开发的SAW收发器具有更小的体积,顺应了移动电话小型化的发展潮流。
村田制作所企划管理集团宣传部部长大岛幸男表示:“我们今后将有3个重点发展方向,即无线通信、传感器和节能。此次展出的产品和技术,特别是村田顽童,对整个产业的各个领域都有很大的应用和借鉴价值。”
【关键词】博物馆 数字化展览 展示技术
博物馆是国家和地区进行文化和文物保护的重要途径,其作用主要体现在对文物的展示以及相关知识的教育和传播上。博物馆作为人类社会中的一种文化传播形式,其特点也在随着社会的发展而不断发生着深刻的变化。近年来数字技术的发展为博物馆的功能完善提供了有效的途径和良好的工具。数字技术在博物馆建设管理中的应用不仅提高了展览的观赏性、艺术性,还能使各项工作的组织更加的协调、安全、有序,为参观者带来更好的感官享受,同时也进一步提高文化宣传和教育的效果。博物馆的数字化展示主要是通过算机技术的应用将博物馆中的实体文物转换成相应的虚拟信息,参观者可以根据自己的需求选择合适的信息进行浏览,这样不仅提高了博物馆的工作效率,还能更好的体现服务的人性化和多样化,完善了博物馆的功能。
1 博物馆展示设计的产生与发展
博物馆兴起于18世纪的工业革命以后。在当时人们已经初步认识到了博物馆对文化教育与宣传的作用,并开始利用博物馆进行一些历史文化知识的学习。博物馆在发展初期主要发挥了教育功能。为了更好的扩大其影响,很多博物馆逐渐将藏品与存储藏品的库房进行分开设置,这样就能腾出更多的空间进行藏品的展示。这就是最初的博物馆展示。从20世纪初期开始,博物馆的发展方式开始产生一定的变化。自然科学博物馆首先在英国出现。这种博物馆改变了传统的藏品陈列方式,在传统的文字说明基础上开始增加了相应的图片、图解以及模型对藏品进行更加深入的介绍。随后,英国的自然科学博物馆又最早开始使用标准化的博物馆陈列柜,并对陈列柜的材质进行了严格的筛选,以确保更大的储物空间[1]。到了21世纪,博物馆的发展向着更加多样化、人性化和数字化的方向发展。博物馆属于社会的非盈利机构,其主要的功能是向大众展示一些文物以及这些文物背后所包含的文化意蕴和内涵。博物馆中的藏品不仅是历史遗迹,也是人类文明发展的见证。现代博物馆博物馆的建设还是一门综合性的学科,结合了心理学、建筑学、美学等多个领域。博物馆还具有很强的研究和学术价值,是信息交流和传播的重要途径。与此同时,博物馆也是权威的机构,能够为大众提供最为专业性的文物知识,因此,博物馆也具有普及教育的功能。
2 博物馆展示的特点
2.1 博物馆展示信息传递的载体
进行博物馆展示设计的主要目的是为了促进信息传递的效果和效率。从这一层面上来说,展示设计的实质是一种信息传播的媒介。信息的传播是需要有一个完善的系统的,并不是简单的信息接收和传递,在这一过程中还需要对信息进行相应的处理和加工。而展示设计就是通过各种媒体的应用为信息的传递创建这样一个体系,并引导参观者参与到信息传播的过程中,以体验的方式对信息进行直观的感受。计算机技术以及信息技术的发展使得数字技术成为了博物馆信息传播过程中的重要环节。当前许多新建成的博物馆都是数字技术与信息技术结合的产物,在实际应用的过程中也展现出了良好的效果。
2.2 博物馆展示设计是多学科交叉的综合体
现代的博物馆展示设计是多个学科交叉综合的产物,其中涉及的学科包括传播学、建筑学、美学、社会学等。现代博物馆将艺术与科技进行了完美的融合,有效的汲取了各个学科的精髓,又在此基础上形成了其自身的特点和发展规律。
2.3 博物馆展示的交互性
展示是博物馆进行知识和文化传播的主要途径,也是实现与参观者互动的一种方式。要形成良好互动的关键在于沟通的有效性。要形成一个良好的沟通,必须满足三个要求。首先,信息必须有良好的针对性。面对不同的沟通对象时,所采用的信息内容和形式也是有所不同的。其次,在信息沟通的过程中需要根据反馈对信息进行及时的调整。最后,沟通的过程必须是双向的,只有这样才能确保良好的沟通效果。在进行博物馆的展示设计时,首先要考虑的是信息沟通的对象是谁,其次需要根据沟通的对象选择合适的沟通方式,以达到理想的沟通效果,实现信息与参与者之间良好的互动。
3 博物馆展览方式的类型和设计特点
3.1 从观众感官行为上分类
从感官上划分,博物馆的类型可以分为视觉符号的传递以及听觉符号的传递两种类型。博物馆中有很多藏品都是通过视觉信息进行传递的,包括图片、文字、雕塑、视频等。除了视觉符号外,听觉符号也是博物馆中信息传递的重要方式之一,例如许多藏品前都会有语音提示,这是通过红外装置感知参观者的位置,当参观者位于展示品的附近时就能自动产生语音提示。多种形式的感官符号极大的丰富了信息传递的途径,也能提高展品展示的效果。
3.2 从展示内容上分类
博物馆的展示内容主要有两种类型,分别是实体展品为中心以及媒介信息为中心的展览方式。以实体展品为中心的展览方式是最为传统的。这种展览方式将展品以最客观直接的方式呈现在参观者面前,没有过多的说明,观众主要通过对展品的观察和欣赏来形成自己对展品的理解。当前,我国大多是博物馆仍然采用这种传统的展览方式。这种展览方式的特点是展品以实物为主,在展览的过程中展品就是重点和中心。这种展览方式能够充分的体现展品自身的价值和意义,并将展品内涵以最完整、原始的方式呈现出来。观众通过视觉、听觉等感官对展品进行直观的感受。
第二种展览方式是以媒介信息为中心的展览方式。信息技术、数字技术的发展使得网络平台在博物馆中的应用日益广泛,同时也为媒介信息为中心的展览方式发展奠定了基础。通过数字媒体技术的应用,能够为参观者建立一个既具有空间引导意义,又具有信息自动展示的综合服务系统。随着信息技术的进一步发展和普及,信息技术在未来也将成为博物馆建设过程中的核心技术。博物馆本身作为信息传播的重要方式,也具有很大的价值,以媒介信息为中心的展览方式在实体展品的基础上提供了更加丰富的展示形式,能够更好的体现出博物馆的文化底蕴,凸显博物馆的教育意义。
3.3 从物的表现方式上分类
物的表现方式有很多种,主要的类型包括剧情发展展览方式、场景陈列展览方式、形式对比展览方式、重点陈列展览方式、聚集陈列展览方式等。这几种展览方式各有其特点。剧情展览方式是将整个博物馆的展览过程看成一个开端、发展、、结尾的剧情发展过程[3]。简单的来说,剧情发展展览方式就是将展品通过讲故事的方式介绍给观众。这种展览方式不仅显得逻辑清晰有条理,而且具有较强的趣味性,能够帮助参观者对博物馆的展品形成系统性的了解。一般历史革命博物馆、地方志博物馆都会采用这种展览方式,将历史事件通过剧情的方式串联起来,让参观者根据一定的时间或逻辑顺序进行参观。
第二种是场景陈列展览方式。这种展览方式一般是通过选取某一事件,采用雕塑、模型等方式进行展品的展示。选取出来的事件一般具有较强的代表性,对参观者有较大的吸引力和感染力。例如,大庆石油博物馆就选取了“王进喜打井”这一耳熟能详的事件,以王进喜打井的工具以及其日常生活中的工具作为主要的陈列对象,将当时打井的景象进行了重现,并通过声、光、电等效果进行艺术的渲染。
第三种展览方式是形式Ρ日估婪绞健3S玫亩员确绞桨括古今对比、新旧对比、色彩对比等方式。这种对比的展示形式能够给观众留下更加直观的感受和深刻的印象。大英博物馆在进行雕塑的展示时就采用了这种方式,通过巨型雕塑和小型浮雕的对比让参观者感受到展品的魅力。
第四种展览方式是重点陈列展览方式。这种展览方式一般应用于主题博物馆的展示上,展览的过程围绕一个主题展开,根据主题突出展示的重点。例如,常州的中华恐龙园博物馆就采用了重点陈列展览的方式,将恐龙作为展示的重点,根据不同时代、不同类型对展品进行了分类。
3.4 从交互方式上分类
博物馆在与观众进行沟通时最重要的手段是展品的展示,而交互作为信息沟通的主要渠道,承担着主要的信息传达功能。信息的传递是由传递对象、传递渠道、双向沟通这三个方面组成的。在进行博物馆的设计时需要从人、物、场景、时空这几个方面入手,做好这几个方面要素的协调与统筹,为参观者提供多感官的体验,实现与信息的积极互动。博物馆的信息传递并不是简单的信息收发,而是具备信息处理和调整功能的互动式传递。强调交互式的信息传递方式能够将以往以展品为主的被动参观模式转变为以参观者需求为主体的主动参观模式,更好的调动参观者主动参与的意识。例如,上海的科技博物馆建造了一个可以模拟地震效果的电动盒子,置于这个盒子中可以让观众身临其境的体会到不同震级地震的感受,这种直观的体会比大量的文字和图解演说更加的有效。
第二种类型是空间交互展览方式。博物馆的展示空间分为实体空间、虚拟空间、心理空间等三个方面。通过对博物馆的空间进行划分可以引起参观者在心理上的变化,从而与展览的环境形成一定的互动,建立一定的联系。人与环境的互动可以加强环境在人心理上的感染力。
第三种形式是数字智能交互展览的方式。数字技术的应用催生了一系列数字博物馆的产生,如虚拟博物馆、网络博物馆等。数字博物馆为参观者提供了更大的选择空间,他们可以根据自己的需求和喜好选择合适的参观方式。在数字博物馆中,用户也能得到与实体博物馆中相类似的感官体验,可以说数字博物馆是对实体博物馆的一种重要的补充,而且在过程上更加的便捷、快速。
4 博物馆中数字化展示技术的应用研究
4.1 静态平面数字展示技术
静态平面数字展示技术一般是借助照相机、扫描仪等设备对博物馆里的实体展品进行拍摄或扫描,然后通过处理软件对相应的图像进行裁剪、修改与美化处理,最后将其转化为数字图像信息。在博物馆展览中,静态平面数字展示技术的具体应用包括:(1)博物馆可以借助静态平面数字展示技术将一些展品更加清洗的呈现在观众面前;(2)数字展示技术可以解决实物展览中的一些缺陷和不足,大大增加博物馆资源的利用率;(3)由于一些非常珍贵的物品极易受到空气的氧化从而出现破坏,此时可以借助该技术有效解决问题。
4.2 静态立体数字展示技术
博物馆展览中通过静态立体数字展示技术可以对馆藏资源进行有效的呈现,其一般可以借助三维软件对藏品进行实物建模,随后通过Maya、3DMAX等计算机处理软件对立方体、球体等常见几何元素进行针对性的平移、旋转、拉伸等操作,进而构建出一个所需要的立体场景。通过专门的设备仪器对展品的具体结构数据进行详细的测量,对每个展品的表面采样点进行系统的采集,从而获取三维空间坐标,通过数字化可以实现展品立体化数字展示。静态立体数字展示技术与多种数字化图形处理技术结合在一起,可以将一些传统几何建模更加逼真的呈现出来。
4.3 动态平面的数字展示技术
动态平面技术主要有数字化平面交互技术、数字化二维动画技术、数字化影视媒体技术。其中FLASH动画是数字化二维动画技术最为典型的技术;Authorware是数字化平面交互技术中较为典型的技术。越来越多的博物馆开始对自身的网络信息系统进行不断的补充和完善,从而将一些无法展示的展品借助投影、触摸屏等数字展示技术更好的呈现在观众面前,进一步增加馆内资源的科普教育、教学展示。
4.4 动态空间的数字展示技术
动态空间主要是指三维数字动画技术,其一般是借助计算机软件设置和设定展品的尺寸,从而构建出展品的三维立体模型。然后还可以根据展品的实际情况来设定模型的摄像头、运行轨迹、展示场景及光线材质,最终就可以得到我们所需要的三维立体动画。目前,常见的3D软件主要有Maya和3DMax,其一般是借助三维数字动画技术来讲馆藏中一些实物展品信息更好的呈现在观众面前,以达到预期的展览效果。
5 结语
在21世纪的今天,数字技术与网络技术的结合在现实生活中的应用日益广泛,数字技术强大的虚拟现实功能能够在网络空间中为用户提供仿真的三维展示效果,将实体展示与虚拟展示有效的结合起来,为博物馆的发展开辟了新的方向。
