Of all the science technology, I find the sixth sense most interesting. Because I think we will be using it most often daily if released, and also the most useful. I think the freezing body one is cool too! But I don’t think we will use it daily. I think the main faw is that it uses projector, and cannot be seen well  in the sunlight, but I think they can come up with an idea to improve it somehow. Also the sixth sense is really cheap to build, and can easily be manufactured. If everything goes to plan, I think I will see one in the market after three years.
