Aireal: Interactive Tactile Experiences in Free Air by Disney Research Lab

AIREAL is a new low cost, highly scalable haptic technology that delivers expressive tactile sensations in mid air. AIREAL enables users to feel virtual objects, experience dynamically varying textures and receive feedback on full body gestures, all without requiring the user to wear a physical device. AIREAL is designed to use a vortex, a ring of air that can travel large distances while keeping its shape and speed. When the vortex hits a user’s skin, the low pressure system inside a vortex collapses and imparts a force the user can feel.
