Fuji Xerox Co Ltd organized an event called "Shock-a-thon" Aug 2 and 3, 2014, in Yokohama, Japan. At the event, companies and universities lent haptic feedback devices to participants as "materials" so that they can make various systems and applications.

[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.

The "TECHTILE toolkit" is used for the virtual toothbrushing. It was developed by a research group at Keio University, etc. The white box (upper left) is the main unit. There are a vibration device under the left paper cup and a microphone under the right cup. The vibration of the right cup is transmitted to the left cup.

[Rubbing Cheeks Together] This system enables the user to brush his/her cheek with a person in the distance. With the TECHTILE toolkit, when the left person brushes his cheek with the round object that he holds, the vibration is generated by the device held by the right person. The PC screen is showing a concept video.

The vibration, etc generated by the robot (left) moving on the floor is recorded. And, based on it, the user can feel the irregularities on the floor with the tablet computer (right). The gyroscope of the robot detects vibrations. The tablet is equipped with the "SPIDAR-mouse," a tactile device developed by a research group at Tokyo Institute of Technology. When the user touches the screen of the tablet while touching the SPIDAR-mouse, the user feels the irregularities, etc of the floor recorded by the robot.

A system that enables the user to play the role of Zatoichi, a fictional Japanese blind swordmaster. An "ultrasonic wave focusing device" located in front of the user's face emits ultrasound waves in different ways in accordance with the location of the person acting as an "opponent" so that it becomes possible to find the location of the opponent without using the eyes. When the opponent is located to the left, ultrasonic waves come from the left, and vice versa. As the opponent comes closer, the ultrasound waves become stronger. When I used the system, I felt as if wind was blowing to my face and thought it was tickling.
