HUMAN-COMPUTER INTERFACE

摘要

A multimedia human-computer interface includes a position sensitive panel and a display wherein gestures drawn onto the panel by a user are interpreted by gesture processing software, and, according to the gesture input and the context in which it is used, the operating mode of software for the manipulation of images is affected. Typically the panel will be coincident with the display. A programmable library of gestures is stored in a compute system, each gesture corresponding to a particular software function. Gestures may be programmed or reprogrammed to control any suitable operation of the software. The invention provides for the switching of operating mode, as well as the control of parameters associated with a given operating mode. The invention also provides for speech recognition techniques to be combined with the gesture recognition to enhance the functionality still further.
