haptiikka
Haptiikka, in Finnish used to denote the field of haptics, is the study and application of touch-based feedback in human-computer interaction. It covers tactile feedback, which conveys sensations on the skin, and kinesthetic feedback, which conveys forces and motion to muscles and joints. Haptic systems use actuators and sensors to let users feel virtual or remote objects, textures, resistance, or danger cues.
Core technologies include vibrotactile actuators that produce skin-level vibrations, force-feedback actuators that push back against the
Fields of application are broad. In medical training and surgical robotics, haptiikka enables more realistic simulation
Challenges include variability in human perception, differences in skin sensitivity, and the high cost and mechanical
Haptiikka is a cross-disciplinary field within human–computer interaction, combining engineering, psychology, and design to explore how
