Stylus-based pressure-sensitive area for UI control of computing device
Techniques are disclosed for interacting with a computing device using a stylus. The stylus is configured with a pressure-sensitive control feature that can be activated to perform various actions while the stylus is touching or otherwise sufficiently proximate to a stylus detection surface of the device. The pressure control feature function can be associated with a variety of tasks on the computing device such as: adjusting variables, executing a particular command, switching between tools, modifying a particular tool's settings, and launching an application. In some embodiments, the stylus-based pressure-sensitive control feature is configured to allow for squeeze actions, tapping actions, and various combinations of such pressure-types on the pressure-sensitive control feature to uniquely identify a corresponding function to be carried out on the computing device.
