Thermal-Radiation-Based Haptic Display—Laser-Emission-Based Radiation System

When a human places his/her hands over a source of heat, his/her hands become warm owing to thermal radiation. I propose a novel haptic display, which employs thermal radiation to display a virtual shape. A person tends to avoid a heated region at a nociceptive temperature. Using this 3 dimensional thermal control, the system displays the virtual 3-dimensional region. In this paper, I propose the laser-emission-based thermal radiation system for farther range and precise projection.
