How people manage objects with shelves: storage and forage

Computer interfaces have been directly associated with the key metaphor "desktop" for a long time. This should be readdressed, since the rapidly development of technology, such as multi-touch. People manage objects not only on the table top, mostly within a space or environment. This paper presents the results of studies on how people manage objects in space by observing participants handle objects in shelves set. We used qualitative way to analyze the video data. The results show that two hands collaborate very smooth and their role would exchange. Object orientation, attributes, and environmental factors have strong influence on people's behavior. And people would try to review objects and keep things in order. These finding have implications for interface design and we use a case to show them.
