Unlocking doors can be a tiresome process sometimes, especially if you have to carry several different keys with you at all times, but thanks to the development of technology, we might be able to open our locks with invisible keys in the future.
Invisible Key is developed by Tsai Yao-pin, and instead the actual key that you use to unlock the door, you’ll use a specific hand gesture. Tsai Yao-pin got this idea from motion controllers, so he developed a system that can track 3D movement of the hand, and his team from Technology and Science Institute of Northern Taiwan, developed a chip capable of performing such tracking. In order to unlock the door, you just need to setup your gesture, and repeat that gesture in front of the sensor each time when you want to unlock your door.
With Invisible Key, there’s no need for keys or cards, and only thing that you need is your special gesture to unlock the door. As for availability, we should see Invisible Key probably in the middle of 2012.
