Indirect shear force estimation for multi-point shear force operations
Seongkook Heo, Geehyuk Lee · 2013
As a way to enrich touch screen interaction, the possibility of using shear forces is being explored recently. However, most of the studies are restricted to the case of single-point shear forces possibly due to the difficulty of sensing shear forces at multiple touch points independently. In this video, we introduce a novel method to indirectly estimate shear forces using the movement of contact areas. These methods enable multi-point shear force estimation since the estimation of a shear force is done for each finger independently. We also demonstrate the method with a game application.
