Realtime Pointing Gesture Recognition and Applications in Multi-user Interaction

摘要: Pointing is a common gesture of human. Indeed, people tend to involve pointing action in their daily activities using not only bare hand but also with gloves or kind pointers like pens, rulers, long sticks, batons, etc. Thus, this article, the authors propose new concept interaction that centered by natural human and method detect it under various circumstances. Different from some approaches which rely on predefined skin color markers, proposed can segment any pointer tip allow multiple objects be processed at time. The run average accuracy 91.0%. In case users different objects, slightly reduced 87.9%. running time most 17.14 ms for 9 being parallel, thus applied real constraints.
