Combining one or more spatio-temporal sensors (11, 902, 904) with a personal digital assistant (501) or similar small electronic device and with sliding window (roaming and stabilization) software (115) and memory management (120) and user interface functions (130), to enable a user to see documents and objects that appear to be fixed in space. This may allow the user to navigate using his or her eidetic memory. Navigations of images, documents or other objects substantially bigger than the display (125, 903) is made easier and faster. Using the invention, the user scrolls and views larger documents or objects as if they were affixed in space to a selected viewing platform. The viewing platform can correspond to, for example, the ground, a building, a wall, an arbitrary reference point, or any other suitable fixed or substantially fixed position or object. The invention uses and adjusts for the body-arm-hand-finger motion of the user (Figs. 8 & 9) so that the imagery appears to the selected reference platform. |
