HAPTOGRAM

Understanding the Haptogram

The Haptogram is a system that provides mid-air 3D tactile feedback via focused ultrasound without physical contact with the human skin. The tactile sensations are displayed by generating acoustic radiation force. A phased array of ultrasonic transducers is used to exert forces on a target focal point in 3D space. By appropriately controlling the phase of each ultrasound transducer the array can move the focal point rapidly and thus creating a 3D tactile experience. The ultimate goal is to develop a touchable hologram where users experience visual and haptic hologram displays.
