Abstract
In one embodiment, a method includes receiving, at each of at least four receivers of a stylus, a signal from an electrode line oriented along a first axis of a touch-sensing device and determining, by a processor of the stylus, a signal strength of the signal at each of the at least four receivers of the stylus. The received signal has a different signal strength at each of the at least four receivers. The method includes determining, by the processor of the stylus, a tilt direction of the stylus based on the determined signal strength at a plurality of the at least four receivers, and providing, by a transmitter of the stylus, a response signal to the touch-sensing device. The tilt direction includes a direction of the stylus along a second axis of the touch-sensing device and the second axis is oriented in a different direction than the first axis.
