Abstract:
In an electronic system having a processor, a memory, unit, an alphanumeric input device and a cursor directing device, a method of providing a user interface comprising the computer implemented steps of:a) accessing gesture data representing a gesture formed by tracking movement of a cursor moved by a user with said cursor directing device, said gesture data comprising coordinate positions and timing information and having one or more individual strokes;b) generating a multi-dimensional feature vector based on said gesture data;c) providing said multi-dimensional feature vector to a radial basis function neural network for recognition, said radial basis function neural network associating said multi-dimensional feature vector with a gesture category from a predefined plurality of gesture categories and supplying said gesture category as an output value; andd) applying a set of predetermined commands to said electronic system, said set of predetermined commands being associated with said gesture category output from said radial basis function neural network.
