How industrial touch monitors work

The usual interpretation of the haptic technology used for touch-activated control is that the entire action of a key or switch must be completely replicated to be most effective. But in reality, the perceptual sensitivity of human fingers is not so low. Numerous studies have found that neurons in human fingers can detect very small movements if combined with proper acceleration. Under acceleration conditions above 1.5g, only 0.1mm of movement can be perceived by humans as a confirmation response. However, the minimum level of acceleration of 1.5g is not enough to produce the best tactile effect. A more effective tactile effect can be produced by generating an acceleration and a displacement with a strong stimulus. These accelerations and displacements can be seen in the "phase portraits" shown in this article. After the successful electromechanical integration of haptic technology into the haptic interface device, a phase diagram can be generated.
