Haptic Presentation Technology for Conveying 3D Shapes of Object
Making "Tactile TV" a reality

Outline

To make "tactile" or touchable television a reality, we are continuing our research on technology to convey the shapes and firmness of physical objects such as works of art. Our newest development recreates the shapes of objects virtually by letting the user "touch" computer-generated images with their thumb and two fingers.

Features

Presenting multiple stimulation to multiple fingers
The device presents the shape of a three-dimensional object as three stimulation points on the skin of the thumb and two fingers.
Recreating the sense of "grasping" an object
The device estimates the location and angle of the hand as it tries to "grasp" an object and controls the stimulation so that the fingertips are always "on" the surface, virtually recreating its shape.

Future plans

We will continue our R&D to improve the tactile presentation method and develop a more portable device that will lead to a true tactile television for everyone to enjoy.

  • This research is partly being conducted with the University of Tokyo.
