STYLUS FOR ELECTRONIC DEVICES

摘要

A user input system including a stylus and an electronic device. A user may manipulate the stylus across an input surface of the electronic device and the movement may be detected using axially-aligned electric fields generated by the stylus. The stylus may also include a force-sensitive structure that can be used to estimate a force applied to the electronic device by the stylus.

主权项

1. A stylus for providing user input to an input surface of an electronic device, the stylus comprising:
a body; a tip assembly positioned relative to an end of the body and configured to contact the input surface, the tip assembly comprising:
a first electric field generator configured to produce a first electric field that indicates a point of contact between the tip assembly and the input surface; anda second electric field generator, offset from the first electric field generator and aligned with a central axis of the body, the second electric field generator configured to produce a second electric field that indicates an angle of the body relative to the input surface; and a force-sensitive structure disposed within the body and supporting the tip assembly, the force-sensitive structure comprising a force sensor configured to determine a force applied by the tip assembly to the input surface.
