Object-action association: a HCI design model

While developing the Simple Gesturing User Interface (SGUI) API for incorporating simple gestures into personal digital assistant (PDA) user interfaces, we developed an object-based HCI model and design process. The model assists designing direct manipulation interfaces by proposing that all interface objects are amenable to user manipulation. The model extends object-action interface models by emphasizing the relationship between the interface objects and their actions, object-action associations. We delineate three association properties: directness, localness, and appropriateness. We illustrate the design process and the utility of SGUI by developing Experimental Assistant, a graphing software for high school science experiments on the PDA Categories and Subject Descriptors H.5.2 [User Interfaces]: Theory and methods General Terms Design, Human Factors, Theory. Keywords User-interface design, model-based interface design, object-action interface, gestures, gesturing user-interface,...
