Actronika provides advanced solutions that enable person-machine communication through touch. Haptic interfaces can in many cases operate on their own or synergistically with visual and auditory displays when the fundamental neural principles of multisensory integration are observed. The idea of using the sense of touch in human-machine interaction is more than one century old. It was popularized by the mobile device industry for notifications through buzzing vibrations, or in simulators for training through force feedback.
