ABSTRACT:
An interactive video display system with tight coupling between user-input and the images displayed to provide a feeling of real control by the user. A library of frames of video data is stored in randomly accessible data locations, such as an optical video disc. The video data in each frame in the library is assigned a virtual position in a pre-defined data space, such that the visual image in each frame is related to visual images in other frames by virtual position in the data space. User input is provided through track ball or mouse generating displacement signals. The input signal is translated to an updated virtual position in the data space relative to a previous virtual position and the next frame having the updated virtual position is displayed next.
