Determining Hover Distance of an Active Stylus |
摘要 |
In one embodiment, a change in capacitance at one or more capacitive nodes of a touch sensor of a device is detected. The change in capacitance is detected in response to a stylus being in proximity with but not touching the touch sensor. The stylus includes one or more computer-readable media embodying logic and one or more electrodes for effecting charge transfer wirelessly in the device through the touch sensor of the device. The change in capacitance is analyzed to determine a distance between the stylus and the device.
