With the heartbeat indicator mouse, you can check your e-mail and heart condition at the same time. When the user is using the mouse, the thumb and palm will touch the sensors located inside, and they detect the users heart rate. In some cases it sends the information obtained, to hospitals and caregivers cell phones via PC network. It also tells you how long you’ve worked. “I would recommend it for use in social chat rooms (match.com). The faster your heart beats, the more chemistry there is between you and the person you’re communicating with.” 

Designer: Chiu Chi Tat & Tsoi Man Hei. Not sure if the mouse is available for sale or it’s a just a concept. (yankodesign)
