Laboratory for New Media 18th Exhibition
“Activate yourself! Project for lazy athletes”
Laboratory for New Media Permanent Exhibition periodically updates contents of exhibitions to introduce the various possibilities of expression provided by information science and technology.
Are you exercising enough?
We know that moving the body is good for health. However, it is difficult to get ourselves to start, or to continue. If only there was something to trigger motivation. There is some good news for such lazy people. All you need to do is to arrange technology in a way that enables you to begin exercising naturally in your everyday life. We describe this as “health innovation by daily exercise,” and engage in research and development to achieve it. Everyone can be active in the society of the future!
KOKOROMO uses Smart Sensing Wear technology, which incorporates various sensors into clothing. Since it is worn next to the skin, it can obtain biological data such as electrocardiogram data regularly from the body without causing the user stress and free from clumsy equipment. Exercise load, stress, and other aspects of the body’s condition are analyzed based on the accumulated data, enabling prompt response to any area that might require attention.
When ultrasonic loudspeakers are used, it is possible to propagate sound to a linear region in a straight line, just like a spotlight. By mounting this on an electric platform, it becomes possible to freely control the direction to which sound radiates. Hence, the device is able to track and deliver sound to an athlete even when he or she is moving. This exhibit features a device that targets and continuously chases a specific person standing in front of the loudspeakers.
Setting the region in which a sound can be heard using ultrasonic loudspeakers, delimiting the sound spaces and sharing the same space, is known as “space sharing.” If the radiation plate of the ultrasonic loudspeakers is a flat surface, the sound is able to reach a linear, narrow range. If the radiation plate were transformed to a curved surface, the range of the sound would become fan-shaped, and it would then be able to reach even more people. At the exhibition, visitors can experience changes in the range that a sound can reach by repeatedly changing the shape of the radiation plate.
Ultrasonic loudspeakers demodulate, through mutual interaction, multiple ultrasonic waves that human beings cannot hear, and play back these sounds as audible sounds. This is applied to the output of multiple ultrasonic waves through separate loudspeakers and playing back sound at only one point where they intersect. The spherical audible range that is generated through this method is known as “audio-spot for minimum area.”
Last but not least, experience the birth of the urban landscape through bio-signals, which are generated through exercising in cooperation in a team of three (including yourself). If each person puts strength into his or her arms, a weak electric signal will be transmitted from the muscles into the sensor wrapped around the arm. Corresponding with this, a city will form in front of your eyes, full of color and with vibrant energy. The music that pours over you is music that can only be heard by you, performed through your muscles.
