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