Detection of Attack Velocity Features in Capacitive Touch Sensor Data
First Claim
Patent Images
1. A method for estimating attack velocity, the method comprising:
- providing a surface that is configured to allow a user to touch the surface;
receiving output from a capacitive touch sensor coupled to the surface when the user touches the surface;
estimating an attack velocity from a sequential stream of output values resulting from the capacitive touch sensor when the user touches the surface.

Abstract
Systems and methods for detecting attack velocity features from a single capacitive touch sensor or an array of capacitive touch sensors. In one example, the method uses sequential capacitive touch sensor data to estimate the velocity at which the sensor was touched.
