BuruNavi3: tiny but powerful sensation of being pulled

We have succeeded in developing a thumb-sized force display for experiencing a kinesthetic illusory sensation of being continuously pulled. Previous version having a crank-slider mechanism succeeded in producing a similar sensation, but had limitations in its size and weight. We overcame these limitations by using a thumb-sized actuator that oscillates asymmetrically. User quantitative evaluation indicates that specific asymmetrical vibration is effective to create kinesthetic illusory sensation of being pulled. Small and light-weight force display will be useful for a handy somatosensory-based navigation system.
