Using low resolution vibrotactile actuator grid to produce high resolution haptics
The project presents the concepts behind development of two arm bands which can be used for vibrotactile haptics in human computer interactions. To generate high resolution dynamic tactile patterns on the skin using a low resolution grid of vibrotactile actuators, the project develops on the experiments and findings of the Surround Haptics technology developed by Disney Research.
The project is based on the control of two psycho-physical illusions - Apparent tactile motion and Phantom Tactile Sensation. The arm bands are made of a sheet of plastic commonly used in making beach balls. Each band consists of two vibrotactile actuators (http://www.robotshop.com/en/solarbotics-vpm2-vibrating-motor.html). The configuration of the vibrotactile actuators is shown in the image on the right above.
The project was successfully able to generate 9 different type of continuous and discontinuous tactile motions. The motions generated are depicted in the pictures below.
