The possibility of using shear forces is being explored recently as a method to enrich touch screen interaction. However, most of the related studies are restricted to the case of single-point shear forces, possibly owing to the difficulty of independently sensing shear forces at multiple touch points. In this paper, we propose indirect methods to estimate shear forces using the movement of contact areas. These methods enable multi-point shear force estimation, where the estimation is done for each finger independently. We show the feasibility of these methods through an informal user study with a demo application utilizing these methods.
