Abstract
A device, communicative with a PDA and comprising a movable part, that inputs to the PDA information about all or some of the six spatial variables of the movable part within a space that may be appreciably larger that the PDA and its display screen. The device may serve to conveniently input graphical and symbolic information, in place of a touch-screen, as well as to control multi-dimensional position and orientation of virtual objects in a natural analogous-motion manner. It may also be used in conjunction with an external passive keyboard to input alphanumeric information and commands.
