Heartbeat / entertaining product

Heartbeat has a good flutter. Though it's impossible to show your heart, you can deliver your beating heart through Heartbeat. It's possible to feel your beating heart through Heartbeat, even though you cannot be with someone you like. From the moment you press the button inside the protrusion, the sensor works. It measures your pulse for a minute, and records the pulse which was measured, first. The photodetector built in the sensor calculates light absorbtion cycle with the amount of infrared light passing through the fingers, and measures your pulse. When you grap it in your hand, it beats like a heart to the pulse.
