Collision detection for a haptic interface

In this paper, a new collision detection method, which can detect collisions for hand-based haptic interface efficiently, is presented. This method relies on a hybrid bounding volume of oriented bounding box (OBB) and axis-aligned bounding box (AABB) called OBB-AABB. It uses OBB and AABB to bound the sophisticated objects (such as the virtual hand) and the simple objects respectively according to the objects´ characters. This method, based on Liang-Barsky clipping algorithm, has been implemented using a haptic glove. The experiments show that the newly proposed method is suited for detecting collisions between the virtual hand and virtual objects, and that users can get a quite real feeling of force feedback when interacting with the virtual environment using a haptic glove.
