Reduce, then illustrates the hand stroke to the left of user.Similarly, the hand of user is formerly judged at the right side of optical receiver 22, if
Electric signal corresponding with the optical generator in left side 21 gradually increases at this time, and electric signal corresponding with the optical generator on right side 21
Gradually increase, then illustrates the hand stroke to the left of user；If electric signal corresponding with the optical generator in left side 21 is gradual at this time
Reduce, and electric signal corresponding with the optical generator on right side 21 is also gradually reduced, then illustrates the hand stroke to the right of user.Cause
This, user can not also need to be in direct contact electronic device 100 and can be input operation instruction to electronic device 100.
