A haptics interface is a system that allows a human to interact with a computer through bodily sensations and movements. Haptics refers to a type of human-computer interaction technology that encompasses tactile feedback or other bodily sensations to perform actions or processes on a computing device.
Techopedia explains Haptic Interface
A haptics interface is primarily implemented and applied in virtual reality environments, where an individual can interact with virtual objects and elements. A haptics interface relies on purpose-built sensors that send an electrical signal to the computer based on different sensory movements or interactions. Each electrical signal is interpreted by the computer to execute a process or action. In turn, the haptic interface also sends a signal to the human organ or body. For example, when playing a racing game using a haptic interface powered data glove, a user can use his or her hand to steer the car. However, when the car hits a wall or another car, the haptics interface will send a signal that will imitate the same feeling on user’s hands in the form of a vibration or rapid movement.
