| Research Abstract |
In a virtual reality, various haptic displays are proposed. Phantom, Spider, Haptic Master, Haptic Gear and so on are famous for haptic display. However, they are earth-grounded type and it becomes limitations for use. Then, this research aims to develop a wearable haptic display to improve the flexibility of force presentation mechanism. We thought that it is necessary to consider human body information to develop a wearable mechanism. The key role muscles for action are paid to attention. In this research, EMG of muscle when operating were measured, and a muscular activation patterns were detected. To promote the activation of the muscle, a wearable suit was developed that arranges the artificial muscle to disturb activation of muscle.
In the first year, the target operation was set to pull action. The protector of the ice hockey and the pneumatically-driven artificial muscle were used. And A wearable suit was developed that arranges the artificial muscle that disturbs the operation o

f an important muscle. The experiments were executed wearing developed suit that presented the force was built based on the load curve obtained from important muscular EMG. As a result, by using the curve generated from important muscular EMG for force, suitable haptic display for man's operation sense can be developed. However, it has not enough accuracy caused by the air pressure drive method and weight of the suit must be reduced.
Second year, a wearable suit based on the DC servo motor was developed. It include the control circuit that controlled the force with the DC servo motor and control software using C++ language. And, operation of lifting weight was targeted. The presenting force curve was generated using the muscular EMG. Here, the comparison and the examination were executed while measuring muscular EMG at actual operation. As a result, the effectiveness of the pattern of the presented force curve was confirmed. And, as a method compare with this method, CVT and air force type haptic displays are considered. Less
