Abstract
It is important to reproduce the realistic palpation for the injection
training system based on VR (Virtual Reality). The haptic texture on the
surface of a virtual human body is one of the approaches for realistic
reproduction. The conventional haptic texture, however, has the problem
that the directionality of the reaction force is unconsidered. In this
paper, the DHT (Directional Haptic Texture) is introduced to solve the
problem of the conventional method. It is difficult to store the huge amount
of pre-computed DHT data into the memory. Then we use a graphics processor
to achieve the real-time calculation. The effectiveness of the proposed
method has been compared with the conventional method. By using DHT, we
have developed the VR injection training system with realistic haptic sense.
