Abstract—The objective of this study is the development of the device gives direction of power vector for the disabled. The device made up of 4 stack linear oscillatory actuators on each 3-axis (X-axis, Y-axis, Z-axis). These actuators are mounted on the acrylic base plate. This base plate was embedded in the resin sphere with a diameter of 50mm. We can feel the direction of power using this device. Angles intended to display are transform to the spherical polar coordinate in our device. The microprocessor makes PWM signals based on the spherical polar coordinates. These PWM signals drive 12 actuators. In the future, it will be possible to guide the visually-impaired in arbitrary direction and to feedback the haptic sense of EMG prosthetic hand.

Index Terms—Linear oscillatory actuators, haptic device, EMG.
