haptika

Haptika is a term sometimes used to refer to haptics, the science and technology of touch. It concerns how tactile and kinesthetic feedback is perceived by humans and how that feedback can be generated and controlled in interactive systems and devices. Haptika spans perception research, human factors, computer science, mechanical engineering, and design, and it seeks to create believable touch experiences in digital environments.

The field distinguishes tactile feedback, which concerns sensations on the skin such as vibration, texture, and temperature, from kinesthetic feedback, which conveys force, weight, resistance, and movement through joints and muscles. Technologies used in haptika include various actuators (vibrotactile motors, piezoelectric elements, voice coils), force-feedback devices, and newer approaches such as electrostatic or ultrasonic mid-air haptics. Haptic rendering algorithms translate virtual interactions into tactile stimuli, while sensors capture user input to drive the feedback loop. Devices range from handheld controllers and data gloves to full exoskeletons and prosthetic interfaces.

Applications of haptika appear across virtual reality, gaming, medical simulation and training, teleoperation and robotics, automotive and consumer electronics, and remote collaboration. In research and development, metrics such as latency, fidelity, perceptual thresholds, and comfort are used to evaluate haptic systems.

History and terminology vary by region, but the core idea is to augment or substitute touch in human-computer interaction. As technology advances, haptika aims to provide more immersive, safe, and accessible tactile experiences in both professional and consumer contexts.
