Abstract
We propose a VR-based injection training system using Simulated Patient (SP) with an original haptic needle which can represent a haptic expression. SP is trained to realistically portray a real patient. In order to increase a realistic sensation and effect of training, it is important to train with real human. Therefore we propose a new training system which fuse SP and virtual training system. In the proposed system, trainee can virtually puncture the SP using the haptic needle. In addition, the haptic needle can represent a haptic expression of needle insertion of the virtual anatomical model. We developed the haptic needle which can represent a reaction force of puncturing. A reaction force of needle insertion is generated by clipping needle by using computer-controlled electromagnet and permanent magnet, and then a friction force is accrued. By using the proposed system, trainee can feel virtual puncture as well as operating for real patient.
