Design mobile phone with a physical keyboard. Location cameras on the sides of the device. Three-dimensional dynamic interface with audio accompaniment.
I suggest a mouse with full keyboard input capabilities. Not only does this free up space on your desk where the keyboard used to be, but it also teaches you an easier method of touch typing. Just as when you work with a mouse you look only at the screen and not at your hand, so in my device you also do not look at your fingers when you type text. You just have to look at the screen.
