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.
Claims20
A method comprising:
- measuring, by an input device, a strength of a magnetic field of a near-field communication;
- transmitting a first data indicating the strength of the magnetic field, which is measured by the input device, to a device;
- determining, at the device, a hover distance of the input device 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 input device.
2 more elements
One or more computer-readable non-transitory storage media embodying logic that is operable when executed to:
- receive, at a device, first data transmitted from an input device, the first data indicating a strength of a magnetic field of a near-field communication which is measured by the input device;
- determine, at the device, a hover distance of the input device in reference to the device based at least in part on the first data;
- and
- operate the device based at least in part on the hover distance of the input device.
1 more element
An input device comprising:
- one or more electrodes configured to wirelessly transmit signals to and receive signals from a device;
- and
- one or more processors configured to:
- measure a strength of a magnetic field of a near-field communication;
- transmit first data, via the one or more electrodes, to the device, the first data indicating the strength of the magnetic field, wherein the device is operable to determine a hover distance of the input device in reference to the device based at least in part on the first data;
- and
- control operation of the input device based at least in part on the hover distance of the input device.
