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.
