Abstract: In one embodiment, a stylus with one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device has one or more sensors for detecting movement of the stylus.

Abstract: In one embodiment, computer-readable non-transitory storage media receive one or more signals based on motion of an object, a device, or both. The received signals are compared to a motion profile which defines unintended motion of the object, the device, or both, and this comparison determines whether any of the signals represent unintended motion of the stylus or device. The received signals are then processed to correct for the unintended motion defined by the motion profile.
