haptisen

Haptisen is a Finnish term used to describe haptics or tactile feedback in human–computer and human–robot interaction. In English-language usage, haptic or tactile feedback refers to sensations produced by a device to convey information or simulate contact, through the sense of touch. The field covers both tactile feedback, which stimulates the skin (vibration, pressure, texture), and kinesthetic feedback, which applies force or resistance to move or hold objects.

In practical terms, haptisen technologies are found in consumer electronics, virtual reality, teleoperation, and medical rehabilitation. Examples include smartphone vibration for alerts, game controllers with force feedback, wearable devices that deliver gentle pressure, and advanced prosthetics that convey sensations to the user. In surgical simulators and rehabilitation systems, haptics help users feel simulated tissue properties or grip forces, improving realism and training outcomes.

Technologies used to realize haptisen effects include mechanical actuators such as vibration motors, linear resonant actuators, and voice-coil actuators; electro-tactile or magneto-tactile stimulation; and, in some approaches, ultrasonic or magnetic fields for contactless feedback. Researchers study perception thresholds, latency, resolution, and ergonomics to create convincing and safe touch experiences.

Etymology and usage: The term haptics derives from Greek haptesthai, meaning to touch. The Finnish word haptinen or haptisen is used in technical and academic contexts to describe touch-based interaction and devices, and is related to the broader international study of haptic technology.
