Abstract
A computer-implemented user interface method is disclosed. The method includes displaying information on a touchscreen of a computing device, receiving from a user of the device an input drawn on the touchscreen, correlating the input to a template, where the correlating includes employing a closed-form solution to find a rotation that reduces angular distance between the input and the template, and providing output based on a result of the correlating.
