First Claim
Patent Images
1. A method comprising:
- receiving, at a device, first data transmitted from a stylus by near-field communication, wherein the first data comprises a strength of a magnetic field as measured by the stylus;
determining, at the device, a hover distance of the stylus in reference to the device based at least in part on the first data; and
operating the device based at least in part on the hover distance of the stylus.

Abstract
In one embodiment, a method includes receiving, at a device, first data transmitted from a stylus by near-field communication. The first data comprises a strength of a magnetic field as measured by the stylus. The device determines a hover distance of the stylus in reference to the device based at least in part on the first data. The device is operated based at least in part on the hover distance of the stylus.
