17 Jun 2016TL;DR: In this paper, a touch interface device that produces tactile and audio output comprising a touch surface, an first electrode coupled to the touch surface that receives a first haptic/audio output potential, a second electrode coupled with a low impedance return path to the device, the first and second electrodes being configured such that when both the first, second electrodes are touched by an appendage of a user, a current flows between them, where the current creates an electric field that imparts a controlled electrostatic force at interfaces of the first electrode and the appendage, and wherein the electrostatic
Abstract: A touch interface device that produces tactile and audio output comprising a touch surface, an first electrode coupled to the touch surface that receives a first haptic/audio output potential, a second electrode coupled to a low impedance return path to the device, the first and second electrodes being configured such that when both the first and second electrodes are touched by an appendage of a user, a current flows between the first and second electrodes and the appendage, where the current creates an electric field that imparts a controlled electrostatic force at interfaces of the first electrode and the appendage, and wherein the electrostatic force provides tactile feedback to the appendage of the user and causes vibration in the surrounding air that is audible to the user.

09 Jun 2016TL;DR: A touchscreen includes conductive islands that are capacitively coupled to conductive traces, where they may be used to provide capacitive sensing of the position of one or more fingers in contact with a touchscreen.
Abstract: A touchscreen includes conductive islands that are capacitively coupled to conductive traces, where they may be used to provide capacitive sensing of the position of one or more fingers in contact with a touchscreen and/or to exert haptic forces on one or more fingers in contact with a touchscreen.
