A gesture-controllable system that uses proprioceptivity to create an absolute reference system

摘要

A system has a contactless user-interface for control of the system through pre-determined gestures of a bodily part of the user. The user-interface has a camera and a data processing system. The camera captures video data, representative of the bodily part and of an environment of the bodily part. The data processing system processes the video data. The data processing system determines a current spatial relationship between the bodily part and another bodily part of the user. Only if the spatial relationship matches a pre-determined spatial relationship representative of the pre-determined gesture, the data processing system sets the system into a pre-determined state.
