Ikitoiki (Breathing) is a device for measuring biometric information. The measurement of biometric information means understanding a person's health condition and so on by measuring such things as temperature, heartbeat, and amount of exercise. By combining this with behavioral information, it becomes possible to provide appropriate support at all times.
Ikitoiki obtains biometric information from people's voices.
