SYSTEMS AND METHODS FOR CAPTURING AND RECREATING THE FEEL OF SURFACES
First Claim
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 based on the recorded acceleration, force, and speed.

Abstract
Systems and methods for capturing and recreating the feel of a surface are disclosed. A method for capturing a feel of a surface comprises contacting the surface with a handheld tool, recording data measured by the tool, and generating a texture model of the surface based on the recorded data. A method for recreating a feel of a surface comprises contacting a virtual surface with a handheld tool, determining an estimated contact force based on the data measured by the tool, generating a vibration waveform from a texture model based on the data measured by the tool; and actuating at least one actuator of the tool according to the vibration waveform. A system for capturing and recreating a feel of a surface comprises a handheld tool, a storage device, and a processor.
