SYSTEM AND METHOD FOR CALIBRATING AN INPUT DEVICE
First Claim
1. An input device, comprising:
- an input surface configured to be touched by input objects;
a haptic mechanism configured to provide a haptic effect to the input surface;
a force sensor configured to sense force applied to the input surface; and
a processing system communicatively coupled to the haptic mechanism and the force sensor, the processing system configured to;
actuate the haptic mechanism to apply a first force to the input surface,determine a representation of the first force using the force sensor, anddetermine a calibration parameter for at least one of the haptic mechanism and the force sensor based at least in part upon the representation of the first force.

Abstract
The embodiments described herein provide devices, systems and methods that facilitate improved performance in an input device. The input device, for example, may include an input surface configured to be touched by input objects, a haptic mechanism configured to provide a haptic effect to the input surface, a force sensor configured to sense force applied to the input surface, and a processing system communicatively coupled to the haptic mechanism and the force sensor. The processing system may be configured to actuate the haptic mechanism to apply a first force to the input surface, determine a representation of the first force using the force sensor, and determine a calibration parameter for at least one of the haptic mechanism and force sensor based at least in part upon the representation of the first force.
