Abstract
In one embodiment, a stylus includes a first sensor disposed proximate a first end of the stylus. The first sensor is adapted to receive a first receive signal via a first capacitive coupling with a touch sensor of a device. The first end of the stylus is at a tip-end of the stylus. The stylus also includes a second sensor disposed proximate the first end of the stylus. The second sensor is adapted to receive a second receive signal via a second capacitive coupling with the touch sensor of the device. A proximity of the first sensor to the first end of the stylus is greater than a proximity of the second sensor to the first end of the stylus. A widest portion of the first sensor has a greater width than at least a portion of the second sensor.
