Abstract:

Three-dimensional user interface can build a true three-dimensional scene which can not only be loaded with information, but also intuitively fulfill harmonious, natural and highly effective interactive style, so three-dimensional user interface is becoming a trendIn order to find the design strategies of three-dimensional user interface, on the basis of studying the content and design strategies of two-dimensional and two and a half-dimensional user interface, this paper analyzed interactive task, information presentation and user searching behavior under the context of three-dimensional user interfaceThrough integrating users’ needs, spatial behavior and spatial tasks, we constructed the“needs-tasks-gradation model”oriented to true three-dimensional space, which provided a new way to user interface constructionThrough analyzing the design principles of three-dimensional user interface in details, this paper proposed the“design matrix of information presentation”which is instructive to the design of three-dimensional user interface

Key words: three-dimensional user, interface design, information presentation, interactive tasks, needs-tasks-gradation model, design matrix of information presentation
