Abstract: We propose RippleTouch, a low resolution haptic interface that is capable of providing haptic stimulation to multiple ar- eas of the body via single point of contact. This concept is based on the low frequency acoustic wave propagation prop- erties of the human body. By stimulating the body with differ- ent amplitude modulated frequencies at a single contact point, we were able to dissipate the wave energy in a particular re- gion of the bod. This created a haptic stimulation without direct contact. The RippleTouch system was implemented on a regular chair where four base range speakers were mounted underneath the seat and driven by a simple stereo audio in- terface. The system was evaluated to investigate the effect of frequency characteristics of the amplitude modulation sys- tem. Results demonstrate that we can effectively create haptic sensations at different parts of the body with a single contact point (i.e. chair surface). We believe RippleTouch concept would serve as a scalable solution for providing full-body haptic feedback in variety of situations including entertain- ment, communication, public spaces and vehicular applica- tions.
