Virtual keyboard is hard to get used to. Since it involves typing in thin air, it requires a little practice. Only people who are good at typing can use a virtual keyboard efficiently.

It is very costly ranging from 150 to 200 dollars. So not everyone can buy this product.

The room in which the projected keyboard is used should not be very bright so that the keyboard is properly visible.
