Active stylus with force sensor

摘要

In one embodiment, an active stylus includes one or more computer-readable non-transitory storage media embodying logic for wirelessly communicating with a device through a touch sensor of the device. The active stylus also includes a tip configured to receive an applied force and a force sensor configured to receive an inverse transferred force from a force-transfer element. The force-transfer element is mechanically coupled to the tip and configured to apply the inverse transferred force to the force sensor. The inverse transferred force is inversely correlated with the applied force when the applied force is less than a threshold force.

1. An active stylus, comprising:
one or more computer-readable non-transitory storage media embodying logic for wirelessly communicating with a device through a touch sensor of the device; a tip configured to receive an applied force; a force sensor configured to receive an inverse transferred force from a force-transfer element; and the force-transfer element, mechanically coupled to the tip and configured to apply the inverse transferred force to the force sensor, wherein the inverse transferred force is inversely correlated with the applied force when the applied force is less than a threshold force, wherein, when the applied force is less than the threshold force, the inverse transferred force decreases monotonically as the applied force increases.
