Bluetooth Laser Virtual Keyboard

It is a smart design. It is a new technology that I thought
we can only see in the movies; however, it is invented in the real life. People
can only carry it without a bulky keyboard to everywhere. This projection
keyboard is very sensitive although it is a new invention. The battery lasts 2
to 3 hours that I think it is a drawback; maybe it can have a USB device, so
people can plug it into their laptops with no worries. This complete new
invention might get some challenges because some people are not habitual without
the actual keyboard, so it might take some time to make sure its position and
user group in the market.
