Haptic feedback

A modern control element used mainly in apps and games. Haptic technology is extremely touch-sensitive — modern devices with this technology can detect the degree of pressure you are applying. Different levels of pressure result in different effects. In the settings you can turn on the so-called tactile feedback, which means the system feeds you information on your actions. For example, in car racing, you have no pedals, but you have a steering wheel you can turn. If you strongly press the right side, the car speeds up; if you press the left side, the car slows down. If you press the steering wheel with enough force to trigger the brake function, the steering wheel gently vibrates to let you know it worked.
