Design of spatially aware graspable displays

We propose spatially aware portable displays which use movement in real physical space to control navigation in the digital information space within. This paper describes two interface design studies which use physical models, such as friction and gravity, in relating the movement of the display to the movement of information on the display surface. In combining input and output aspects of the interface into a single object, we can improve control and provide a meaningful relationship between the interface and the body of the user.
