Rendering volumetric haptic shapes in mid-air using ultrasound:Proceedings of ACM SIGGRAPH Asia 2014 [PDF]

, 2014
We present a method for creating three-dimensional haptic shapes in mid-air using focused ultrasound. This approach applies the principles of acoustic radiation force, whereby the non-linear effects of sound produce forces on the skin which are strong ...
