Otherwise, the British Standards Institution PAS 78:20xx Guide to good practice in missioning accessible websites provides some remendations on choosing a web designer, particularly for keeping accessibility in mind. Technology requirements In order for the museum to plete the website themselves, basic web authoring and photo manipulation tools are required. Although the choice is up to the museum itself, there is a wide range of tools available in terms of both capability and price. The industry standard tools are Adobe Dreamweaver (formally Macromedia Dreamweaver) for web authoring and Adobe Photoshop for photo manipulation. A reduced price version of Adobe Photoshop, called Adobe Photoshop Elements, is also available and should be sufficient for the image manipulation that is necessary for basic web development. Adobe GoLive and Microsoft FrontPage are also popular web authoring tools. If the museum desires to take the photographs themselves, a digital camera is remended, although using a film camera and scanning is also an option. In general, digital cameras are specified in terms of their image resolution, in mega pixels, and for web photos a camera generating at least four mega pixel images should produce photos of acceptable quality. If the museum wishes to use the camera for printed materials, the investment in a higher quality camera is remended. Important steps Once the content to include in the virtual tour has been identified and the method for creating the tour has been chosen, the next step is to begin the process of virtual tour implementation. There are two primary parts to this: ? assembling the content (taking the photographs) ? implementing the tour (authoring the webpage) Photographs – If the museum has pleted or is in the process of pleting a digitisation project, this would be an excellent source of high quality pictures that are already available. Otherwise, the museum must obtain the photographs of。其設(shè)計背后的理論和操作仍也被寫入。例如 抽象數(shù)據(jù)在軟件工程類型可以很容易地利用虛擬現(xiàn)實表現(xiàn)?，F(xiàn)在的問題是人們是否習(xí)慣索引信息的方式，或新 的和更有效的創(chuàng)新方法。某些系統(tǒng)效用（守護進程）將毫無疑問，在空白的電子表格網(wǎng)絡(luò)空間。內(nèi)部網(wǎng)絡(luò)連接（即一個由計算機網(wǎng)絡(luò)連接內(nèi)部電腦進程管道 和套接字）是許多基于 UNIX 工作站環(huán)境的組成部分。它還如下，其表面會“高亮”顯示給用戶，它即將被激活，或已被激活。為上面四個目錄的新的交互方法必須設(shè)計出，這是網(wǎng)絡(luò)空間交互設(shè)計的挑戰(zhàn)。個人學(xué)習(xí)和性能與風(fēng)格差異很大，如果沒有正確校準(zhǔn)的“身臨其境“的體驗，可能令人困惑，甚至不安。然而，這些會導(dǎo)致信息的內(nèi)部沖突。虛擬現(xiàn)實可以在一個內(nèi)部的環(huán)境讓用戶突破與多種信息形式直接交互的障礙。有了虛擬現(xiàn)實，用戶可以身臨其境，接口可以不通過既 定傳統(tǒng)的鍵盤或鼠標(biāo)，但通過更復(fù)雜的跟蹤系統(tǒng)，保持記錄和方向定位。正是這樣，用這些設(shè)備，你可以和他人分享同樣的虛擬幻覺。 Ports The puter world is moving more towards work environments, not just externally, but work connections (ie. a work of processes on a puter connected by intraputer pipes amp。 the lag is especially noticeable when tracking systems are part of the environment. For example,a lag between when you turn your head and when the screen updates is quite disturbing. Another possibility which is introduced with Cyberspace is sensory overload. Individual learning and preformance styles differ greatly, and without proper calibration an immersive experience can be confusing and even disturbing. According to Bricken, there are four general categories of VR behavior that have to be considered when designing the interface: ?Relocation simple movement ?Manipulation modification of environment ?Construction creation of environment ?Navigation long range location and movement In order to be immersive there can be no menu bar, no list of icons. Without the keyboard there is no hotkeys. All traditional methods of interface are not possible inside the virutal world. New methods of interaction for the above four catagories must be designed that is the challenge of cyberspace interface design. 3. Process Visualization . Surface Activation Most current views of Cyberspace seem to point towards a polygonbased environment. Therefore,in order to keep the experience immersive, no menus can magically popup. Instead, the polygons themselves must be used as an interface method. Since a single shape may have more than one function, it is therefore logical to assign function activation to the surfaces of the object. Each surface then, has to check for collision, and then decide how to react as another object approaches it. This could mean that while you’ re evaluating a certain button, it would also be evaluating you. To make the interface more friendly, surfaces could announce (through text messages or perhaps digitized sound) what their function is. It also follows, that the surface would highlight itself in order to indicate to the user that it is about to be activated, or has been activated. For example, picture a text editor as a box. To edit the file within it you would approach the top, to check the spelling you would approach another side, to delete it yet another side. This may seem a bit cryptic, but with appropriate labeling (either graphic, sound, or text) it would be far easier than current interface methods. Surfaces could have a variety of functions from sending a file or activating a process, to teleporting the user to another work. Certain surfaces would have to be ’ solid’ , or without any type of functionality,in order to allow object manipulation. A primary factor in how an object physically appeared would then be based upon the functionality of its surfaces this could be important as a distinguishing factor between objects. .
