I have an idea to share with you.
My Idea is about computers. Nowadays a lot of people spend all the day in front of the computer. What do we need to use a computer? We need many different things but my idea is about mouse. The whole day we type something on the keyboard and use our mouse. Usually when we use mouse we can't use keyboard because we have only two hands and to type we need all of them.

So my idea is to make a mouse for foot. Our lags usually do nothing under the table of our computer. This mouse could supplement a mouse for hand, or works independently. Nevertheless this mouse will give a chance to increase productivity.
