Method and apparatus for displaying images on a display
Combining one or more spatio-temporal sensors with a personal digital assistant or similar small electronic device and with sliding window (roaming and stabilization) software and memory management and user interface functions, 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. Navigation of images, documents or other objects substantially bigger than the display 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 so that the imagery appears affixed to the selected reference platform.
1. A viewing system comprising:
means for position sensing and processing, wherein said means for position sensing and processing comprises:
a spatio-temporal sensor; and
means for motion compensation connected to said spatio-temporal sensor;
means for image management and rendering connected to said means for position sensing and processing, wherein said means for image management and rendering comprises:
an image source;
a roaming memory connected to said image source and to means for motion compensation;
a rendering engine connected to said roaming memory and to said means for motion compensation;
an image memory connected to said rendering engine and to means for motion compensation;
a display connected to said image memory; and
an image on said display, wherein said means for position sensing and processing detects movement of the device in free space, wherein said means for position sensing and processing detects movement relative to at least one positional reference, wherein the at least one positional reference is external to the viewing system, and wherein moving the display relative to the at least one positional reference reveals on said display a similar movement of the display to another portion of a displayed image; and
means for user interfacing connected to said means for position sensing and processing and to said means for image management and rendering.
2. The viewing system of claim 1 , further comprising means for portability.
3. The viewing system of claim 2 , wherein said means for portability comprises:
small-size enabling capabilities; and
low-power enabling capabilities.
