What is haptic feedback?

Haptic feedback comes under the wider umbrella of haptic technologies, which use the sense of touch to enhance a system. This has become more important as touchscreen and touch-sensitive buttons have replaced many functions that were previously controlled by a physical switches. Haptic feedback usually comes in the form of small vibrations delivered by motors or oscillators similar to the ones in your phone or a game console controller. These vibrations replace the sensation of clicking a physical button to enhance the user interface. You might already be familiar with haptic feedback through your smartphone, but it'll probably play a bigger role in your car as interiors become more screen-heavy. A good example that's already on sale is the Nissan Ariya EV, which has haptic feedback behind its touch-sensitive climate controls.
