Haptics

This article is a stub. You can help Deskthority by expanding it.
Haptics means that an input device has force-feedback: a motor of some kind provides some kind of sensible force, such as vibration or opposite force, as response to user input. The sensation is typically triggered by software that supports the device and not by hardware in the device itself.

Touch interfaces

Vibration or the sensation of click when the touch device is pressed. This is most often used in touch keyboards.

Apple has touch screen and trackpad devices that use haptic feedback tuned to simulate clicks when pressed. They use the trademark Taptic. Some applications sense a harder second-level press - called a Force Touch - which is acknowledged with a second click.

Game controllers

Flight sticks

Some analogue "flight sticks" (for flight simulators) have used force-feedback on the joystick's joint to simulate various sensations such as vibrations and shocks from collisions,

Gamepads

Various gamepads (primarily for consoles) provide vibration as feedback. Some even have a larger and a smaller vibrator.

Mice

Some mice provide resistance to motion and/or vibration. These are rare.

3D pointing devices

One particular class of haptic user interface devices uses a tool (typically a stylus or a ball) attached to a robotic arm with a rotary encoder in each joint.

The robotic arm does not move the stylus by its own - it only provides force in response to user input in the form of movement of the tool or press on a button on the tool.

This allows the user to feel virtual surfaces of various shapes, softness and texture.
