When we are in a meeting, or using the overhead
projector, if we want to type words into the powerpoint,
we have to go back to the computer. If we could add
text by using the mouse and from a distance, we can
lessen the burden of keyboards and would be easier
to carry, the tablet computer can be easily used. The
screen will display the typing interface, and you won't
have to worry about your hands blocking the screen.
All you have to do is look at the screen and operate by
one hand. The side of the mouse is added with Chinese,
English, and number switches, the buttons of Shift, Crtl,
and Alt are also on the mouse.
