MULTI-DIMENSIONAL TRACKPAD

摘要

A multi-dimensional track pad is described that acts as human-machine interface (HMI). Inputs to the HMI can be made not only using the tradition two-dimensional (X-Y) inputs of a track pad, but also a third dimension, force, and even a fourth dimension, time. Tactile or audible feedback to the inputs can be provided. Methods of using the HMI to control a system are described as well as a track pad system that utilizes the HMI in communication with a processor.

1. A method of controlling a system using a track pad comprising:
receiving, by a touch interface positioned over an array of force sensors that are arranged to have a width and a length, a touch force; passing at least a portion of said touch force through the touch interface to one or more force sensors of the array of force sensors; transmitting, by the one or more force sensors of the array of force sensors, force information to a processor in communication with the array of force sensors; determining, by the processor, from the force information a force position along the width and length and a corresponding force magnitude; and sending, by the processor, a control message to a system, wherein the control message is selected depending upon one or more of the force position along the width and length and the corresponding force magnitude.
