Stylus with touch sensor

摘要

A stylus may have an elongated body with opposing ends. Electronic equipment may have a touch sensor that receives electromagnetic signals from one or more electrodes. The stylus may have a touch sensor on the elongated body. The touch sensor on the body may have electrodes that gather touch input and optional force input when the fingers of a user touch the stylus. The touch input may include touch gestures in which a user's fingers move along the length of the stylus and may include rotational information indicative of how the stylus is being rotated between the user's fingers. The stylus may have a force sensor that monitors how firmly the stylus is being pressed against external surface and may have other input-output devices. The stylus may transition between operating modes based on signals from the force sensor and other input-output devices in the stylus.

主权项

1. A stylus that controls electronic equipment that includes a touch sensor and a display, comprising:
a body with first and second opposing ends and a tip at the first end that supplies input to the touch sensor in the electronic equipment; a touch sensor that extends along at least some of the body, wherein the body extends along a longitudinal axis and has a circumference, wherein the touch sensor on the body measures finger touch positions around the circumference, wherein the touch sensor includes a first set of electrodes that run parallel to the longitudinal axis and a second set of electrodes that extend around the circumference perpendicular to the first set of electrodes, wherein the first and second sets of electrodes are coupled to touch sensor circuitry in the body, wherein the second set of electrodes gather touch gestures involving finger movements along the longitudinal axis, wherein the first set of electrodes gather touch gestures involving finger movements along the circumference, and wherein the stylus is configured to rotate an image of an object on the display in response to the finger movements along the circumference; and wireless circuitry that includes a radio-frequency transceiver and an antenna, wherein the wireless circuitry wirelessly transmits touch sensor input from the touch sensor on the body to the electronic equipment.
