Selecting first digital input behavior based on a second input

Abstract

A computing device includes a digital input system that provides digital input functionality for the computing device. The digital input system receives both a first input and a second input. The first input is typically an input with the user's dominant hand (e.g., using a pen, stylus, finger, etc.), and the second input is typically an input with the user's non-dominant hand. The digital input system determines whether a second input is received simultaneously with the first input, and selects one of multiple behaviors for the first input based on whether the second input is received simultaneously with the first input. Various different behaviors for the first input can be selected from, such as freehand or freeform input, constraining digital input corresponding to the first input to be along an edge of a stencil, and so forth.
