Observation-based design methods for gestural user interfaces.
CHI07: CHI Conference on Human Factors in Computing Systems San Jose CA USA April, 2007(2007)
摘要
The design of gestural user interfaces is uniquely challenging because the input is freeform, personal, and often carries subconscious meanings that are domain-specific and difficult to articulate. These features suggest an approach of observation-based design: learning from what people do, rather than relying on what they say. To facilitate observation-based design, this dissertation is exploring two design methods: gesture brainstorming, a Wizard of Oz method for early prototyping of new interfaces, and gesture log analysis, a machine learning-based log analysis method for improving existing interfaces. These design methods will be tested by applying them to two gestural interfaces: a 3D pathway selection interface (CINCH, see Figure 1), and a 3D modeler (Google SketchUp). Experience with CINCH already suggests the utility of observation-based design, while work on Google SketchUp is anticipated to begin this summer. These test cases should inform observation-based design for gestural user interfaces in general.
