摘要:
Described herein is a method for enabling human-to-computer three-dimensional hand gesture-based natural interactions from depth images provided by a range finding imaging system. The method enables recognition of simultaneous gestures from detection, tracking and analysis of singular points of interests on a single hand of a user and provides contextual feedback information to the user. The singular points of interest of the hand: include hand tip(s), fingertip(s), palm center and center of mass of the hand, and are used for defining at least one representation of a pointer. The point(s) of interest is/are tracked over time and are analyzed to enable the determination of sequential and/or simultaneous “pointing” and “activation” gestures performed by a single hand.

摘要:
Described herein is a method and a system for providing efficient and complementary natural multi-modal gesture based interaction with a computerized system which displays visual feedback information on a graphical user interface on an interaction surface. The interaction surface is within the frustum of an imaging device comprising a single sensing system. The system uses the single sensing system for detecting both touch gesture interactions with the interaction surface (120) and three-dimensional touch-less gesture interactions in areas or volumes above the interaction surface performed by hands of a user. Both types of interaction are associated contextually with an interaction command controlling the computerized system when the gesture has been detected. The system comprises preferably a projection system for displaying the graphical user interface and visual feedback on the interaction surface, the projection system being locatable on the same side or on the opposite side of the interaction surface to the sensing system.
摘要:
Described herein is a user interface that provides contextual feedback, controls and interface elements on a display screen of an interactive three-dimensional imaging system. A user interacts with the interface to provide control signals in accordance with those recognized by the system to a makes use of at least one POI in a three-dimensional scene that is imaged by the imaging system to provide control signals for the user interface. Control signals are provided by means of gestures which are analyzed in real-time by gesture recognition processes that analyze statistical and geometrical properties of POI motion and trajectories.
