This thesis analyzes the key issues with Graspable User Interfaces. Unlike conventional GUIs, which typically have only one graphical input device such as a mouse, a Graspable UI provides users with concurrent access to multiple, specialized input devices that can serve as dedicated physical interface widgets. In GUIs, the physical handle is "time-multiplexed", i.e. being repeatedly attached and unattached to the various logical functions of the GUI. Because Graspable UIs allow more than one input device to be used, input control can be "space-multiplexed", i.e. different devices can be attached to different functions, each independently and simultaneously accessible. This allows the interface to take advantage of the shape, size and position of the physical controller to increase functionality and decrease complexity (see comparison chart with traditional GUIs). Some of the examples provided include a digital desk that senses what the users hands are doing, and smart LEGO bricks that sense how they are being snapped together.
