Haptic feedback is the use of touch and vibrations to communicate sensations or feelings to a user. It is a technology that can create an experience of touch by applying forces, vibrations, or motions to the user. Haptic feedback can be used to create virtual objects in a computer simulation, to control virtual objects, and to provide feedback to the user. It is commonly used in mobile phones, gaming consoles, and other electronic devices to provide tactile feedback to the user.

There are different types of haptic feedback, including vibrotactile haptics, sound vibrations, ultrasonic mid-air haptics, microfluidics, force control, and surface haptics. Surface haptics modulate friction between a users finger and a touchscreen to create tactile effects. Force control involves using levers or other large-scale mechanical devices to exert force on the hands, limbs, or full body of a user.

Haptic feedback is used to engage more of the users senses to provide a deeper and more immersive experience. It can improve the user experience by adding the element of presence, providing tactile feedback, and ramping up accuracy at the same time. Haptic feedback is a tool that enhances audio-visual communication and opens up the possibility of creating new products and markets. It is a technology that is still waiting for its breakthrough moment.
