US 2014/0007022 A1 · NATURAL GESTURE BASED USER INTERFACE METHODS AND SYSTEMS

Abstract

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 recognised 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 analysed in real-time by gesture recognition processes that analyse statistical and geometrical properties of POI motion and trajectories.

Dependent claims

A method for interacting with a user interface system using gesture recognition, the method comprising the steps of:

a) forming at least one multi-dimensional representation of a scene within a field of view of at least one multi-dimensional imaging system;
b) performing a multi-dimensional constrained clustering operation on said multi-dimensional representation to provide a clustered representation of said scene;
and
c) identifying point of interest candidates from said clustered representation which can be used for gesture recognition;
and
d) controlling said user interface system in accordance with recognised gestures;
wherein step c) comprises identifying at least one cluster that is connected to only one other cluster and which exhibits coherent motion as a point of interest candidate.
