Multi-Layer Gesture Recognition : An Experimental Evaluation

Gesture recognition techniques often suffer from being highly device-dependent and hard to extend. If a system is trained using data from a specific glove input device, that system is typically unusable with any other input device. The set of gestures that a system is trained to recognize is typically not extensible, without retraining the entire system. We propose a novel gesture recognition framework to address these problems. This framework is based on a multi-layered view of gesture recognition. Only the lowest layer is device dependent; it converts raw sensor values produced by the glove to a glove-independent semantic description of the hand. The higher layers of our framework can be reused across gloves, and are easily extensible to include new gestures. We have experimentally evaluated our framework and found that it yields at least as good performance as conventional techniques, while substantiating our claims of device independence and extensibility.
