Stylus-based slider functionality for UI control of computing device
Techniques are disclosed for interacting with a computing device using a stylus. The stylus is configured with a slider control feature that can be activated to perform various actions while the stylus is touching or is otherwise sufficiently proximate to a stylus detection surface of the device. The slider 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 slider is biased to return to a middle, or home, position thereby allowing for both forward and backward sliding actions. An appropriate animation or sound or haptic response can also be provided that may be indicative of or otherwise related to the action being taken.
