The term “haptic” comes from the Greek and essentially means “tangible”.
Although an individual’s perception of the haptic properties of buttons and controls is subjective, they are a major factor in purchasing decisions.
Evidence of haptic quality is not just of interest in the design phase of the mechanical components. Faults or technological uncertainties in the installation process can result in impairment of the haptic properties of individual controls or keypads.
It is therefore obvious to integrate the haptics test with 100% test coverage in the end-of-line test in component manufacture.
