Abstract
Variations in the manufacturing, tolerances, and environmental conditions, for example, of haptic trackpads can cause mechanical properties to vary click-by-click and unit-by-unit. Also, as time goes, mechanical wear or material degradation within each trackpad may change its mechanical properties. All of which may cause the haptic response received by the user to vary across similarly designed trackpads, and also change over time on the same trackpad. This may be interpreted by the user as an indication of low product quality. The following describes in detail haptic trackpads including accelerometers that enable active control and/or calibration. This allows for a more uniform user experience across a manufacturing run of trackpads and/or throughout the projected life of individual trackpads.
