DYNAMIC, FREE-SPACE USER INTERACTIONS FOR MACHINE CONTROL

摘要

Embodiments of display control based on dynamic user interactions generally include capturing a plurality of temporally sequential images of the user, or a body part or other control object manipulated by the user, and computationally analyzing the images to recognize a gesture performed by the user. In some embodiments, a scale indicative of an actual gesture distance traversed in performance of the gesture is identified, and a movement or action is displayed on the device based, at least in part, on a ratio between the identified scale and the scale of the displayed movement. In some embodiments, a degree of completion of the recognized gesture is determined, and the display contents are modified in accordance therewith. In some embodiments, a dominant gesture is computationally determined from among a plurality of user gestures, and an action displayed on the device is based on the dominant gesture.

主权项

1. A method of controlling a machine, comprising:
sensing a variation of position of at least one control object using an imaging system; determining from the variation of position one or more primitives describing at least one motion made in space by the control object; comparing the one or more primitives to one or more templates in a library of gesture templates; selecting based upon a result of the comparing a set of templates of possible gestures corresponding to the one or more primitives; and providing at least one of the set of templates of possible gestures as an indication of a command to issue to a machine under control responsive to the variation of position.
