Abstract:
1. A method for capturing a feel of a surface, the method comprising the steps of: contacting the surface with a handheld tool, the handheld tool including at least one accelerometer configured to measure an acceleration experienced by the tool, at least one force sensor configured to measure a force experienced by the tool, and at least one speed sensor configured to measure a speed of the tool; recording the acceleration experienced by the tool, the force experienced by the tool, and the speed of the tool while the tool contacts the surface; and generating a texture model of the surface by using the recorded acceleration to calculate a filter by linear predictive coding, the filter applicable to a predetermined input signal in order to output the vibration corresponding to the feel of the surface at the recorded force and speed, the filter configured to create a first vibration corresponding to the feel of the surface at a first combination of force and speed, and configured to create a second vibration corresponding to the feel of the surface at a second combination of force and speed.
