Abstract: A device configured to determine the location and magnitude of a touch on a surface of the device. The device includes a transparent touch sensor that is configured to detect a location of a touch on the transparent touch sensor. The device also includes a force-sensing structure disposed at the periphery of the transparent touch sensor. The force sensor includes an upper capacitive plate and a compressible element disposed on one side of the upper capacitive plate. The force sensor also includes a lower capacitive plate disposed on a side of the compressible element that is opposite the upper capacitive plate.

Abstract: An optical stylus system including an optical stylus and optical sensing system that are together operative to determine one or more of the target or touch location, centroid, hover distance, tilt angle, azimuth, and in some instances the orientation and rotation of the stylus is disclosed. In some examples, light illuminator and detector angular filters are employed to limit the illumination and detection angles of light to minimize false object detection. In other examples, the stylus is a passive stylus with a surface that reflects light with a consistent angular reflection profile or reflected light pattern regardless of stylus tilt. In still other examples, the stylus can detect light at different modulation frequencies emitted from an array of light emitters in the optical sensing system, or the stylus can emit light and detect reflected light with different spectral distributions across the optical sensing system to determine stylus location.
