Abstract:
In one embodiment, a method includes receiving a first signal at a stylus. The stylus is able to wirelessly transmit signals to and receive signals from a device. The stylus includes one or more electrodes in a tip of the stylus. A frequency characteristic of the first signal is determined. A second signal is generated based at least in part on the frequency characteristic of the first signal. The second signal is wirelessly transmitted from the stylus to the device through a touch sensor of the device.
