Abstract: Multi-transmitter stylus tip techniques are described herein. In implementations, a stylus employs a tip having an array of transmitters designed to can convey information regarding the shape, size, and position of the tip in three-dimensional space. The array of transmitters may be arranged in groups or layers disposed at different levels in relation to a three-dimensional volume of the tip. In implementations, the tip is configured as a brush head having a plurality of flexible bristles. In this approach, the array of transmitters may be spread across the bristles to represent or “map” the shape of the brush. A tip may be implemented as an integrated tip that is fixed to a stylus or as an interchangeable tip that is removably coupled to a stylus via an interface and interchangeable with a set of different tips supported by the stylus.
