Input Differentiation for Touch Computing Devices

摘要

Methods for differentiating touch inputs are disclosed. A method detects a touch input by receiving contact at a computing device's touch surface and identifies whether the touch input was received from a stylus based on additional input received from the stylus. The method responds to the touch input, wherein the response differs based on whether the touch input was received from the stylus. The detecting, identifying and responding are performed at the computing device. A stylus has a capacitive tip, a wireless transceiver, and a pressure sensor for determining a pressure level received at the tip. The stylus determines if a pressure level measured by the pressure sensor has reached a threshold, suppresses capacitive output from the tip to a touch surface if it is determined that the threshold has not been reached, and communicates a message to the computing device based on determining that the threshold has been reached.

1. A computer implemented method comprising:
detecting a touch input by receiving a physical contact made at a touch surface of a computing device; identifying whether the touch input was received from a stylus based on additional input received from the stylus; and responding to the touch input with a response, wherein the response differs based on whether the touch input was received from the stylus; and wherein the detecting, identifying and responding are performed at the computing device.
