The operating system window, indicated by the number 1 in Figure 1, Transfer your knowledge about web GUI applications to new Internet access The operating system window 'frame' around the browserįigure 1 A web page displayed with the Netscape Navigator browser.Įach of the basic areas impacts the UI in ways you need to understand to The screen real estate associated with the browser display is divided into three Used to access Internet contenta representative web site displayed in aįigure 1 illustrates a simple web page viewed with a Netscape web browser. You will have toīuild in correlating structures with VUI elements and associated applicationįor the sake of comparison to VUIs, let's examine an example of a GUI There are currently no standard VUI elements that correlate to GUIĮlements such as Home, Back, error dialogs, and online help. Error-causing conditions in applications must be identified and Prompts must be designed to require as little as possible of users' Applications used while driving, walking, working, and so on must be VoiceXML applications exist in part to support a mobileĬulture. VUIs are used in environments that compete for users' attention andĬognitive processing. Compact, task-focused applications maintain user interest and userĪwareness of where they are in an application. Limiting characteristics of VUIs demand a simple workflow with minimalīranching. Single-mode interfaces can't communicate with users as effectivelyĪs multimode interfaces such as WIMP GUIs. Method to a VoiceXML application is soundwhich is also the only output This is the most criticalĭifference between VUIs and GUIs, and drives most of the design

VUIs must be designed to make the lightest possible demands on As far as users are concerned, VUIs exist only in Majorĭifferences between VUIs and other types of UIs you may have designed in the

The task of doing everything it takes to develop a VoiceXML application. Voice User Interfaces (VUIs) are a new concept to many who now have Voice Application Development with VoiceXML
