You ask yourself what haptic feedback is, but the chances are you are experiencing it every day. Haptics are used to give a real feel and sense of reality while using smartphones, game consoles, and car navigation systems.
In fact, whenever you communicate with a piece of technology that provides some sort of simulated physical feedback (as opposed to a physical switch or button), you use haptic technology. The most common example is the vibration of the keyboard in a smartphone, which provides the user with an intuitive feel of successful typing.
Haptic technology works by combining software adjustments and an appropriate physical experience. These physical triggers can be created by a number of different technologies, including instruments that induce vibrations, feedback forces, gusts of air, and even ultrasonic rays that cannot be heard but can be felt.
In most cases, it uses a type of motor called an actuator that converts electrical, hydraulic, or pneumatic energy into vibrations, which can be controlled by software that determines the duration, frequency, and amplitude.
