[Brushing Teeth of Virtual Girl] A system that enables to enjoy the feeling of brushing the teeth of a girl. When the user wears the Oculus Rift head-mounted display (HMD) and holds a toothbrush to which a "marker" is attached, a toothbrush appears in the virtual space displayed by the HMD. The user brings the brush close to the girl's mouth and brushes her teeth. When the brushing begins, the vibration device attached to the brush starts to vibrate. Near the user, there is a person who holds a toothbrush equipped with a microphone. After the brush with the marker begins to move near the virtual girl's mouth, the person starts to rub the brush equipped with the microphone to make a vibration. Then, the user feels the same vibration. The person holding the toothbrush equipped with the microphone uses the screen (lower left) to check if the brushing has started in the virtual space.
