Abstract

In one example implementation according to aspects of the present disclosure, a touch input is received on a touch input region of a computing system, the touch input region being one of a plurality of touch input regions. Responsive to the received touch input, a linear touch input signal and a rotational touch input signal are generated. A discrete cursor movement from a set of discrete cursor movements is then determined and caused to be implemented based at least in part on an analysis of the linear signal and on an analysis of the rotational signal.
