Why do I want another vibrating, noise-making screen in my life? And why do I want it attached to my wrist? I don't, personally, even if it does monitor my heartbeat (and it seems I'm not alone).
BUT WAIT… rewind to that heartbeat monitor… think love… think Tinder… innovation company T3 make the case that when swiping through profile pictures we make relationship decisions with our heads, while we should be making them with our heart, according to the romantics. Enter: Hands Free Tinder.
As you gaze into the pixelated eyes of potential suitors, an increase in your heart rate causes the app to 'match' them. Of course, it's still a dating app and may not replace real life… but I think this is definitely an interesting way of looking at things.
