MOTUS: Rendering Emotions with a Wrist-worn Tactile Display

This paper investigates whether tactile texture patterns on the wrists can be interpreted as particular emotions. A prototype watch-back tactile display, MOTUS, was implemented to press different texture patterns in various frequencies onto a wrist to convey emotions. We conducted a preliminary guessability study with the prototype. The result reveals the wearers' agreement in interpreting the emotional states from the tactile texture patterns.
