Softwatch: A Smartwatch with Virtual Keyboard

Smartwatch is the biggest signal in this IoT age, but because some of its critical limitations such as input method, it kind gets hard time getting as popular as it is supposed to be. But there is always a way to solve the problem, think about what if the way you interect with your smartwatch is not limited in such a tiny screen anymore, it could be exended onto you own arm or wrist, we believe it will be a revolutionary change on Smartwatch, or even wearable devices, industry. With this being said, we are making a smartwatch that is able to project a virtual keyboard on our skin, users can just click buttons on their skin. We are planning on using laser diode to project graphs and time-of-flight sensors to detect fingers' clicking.
