I move to a handwritten input screen by screen chief influence.

Scrolling is the application it's possible to indicate like an electric bulletin board.
When a tap is done during indication, the color changes.
When I slide during indication.
Scrolling speed changes.
It's high for the left and it's slow for the right.
It changes 10 stages.
Screen chief influence shifts to a handwritten input screen during indication.

Even at most 100 frames can be input.
A tap do the right side of the lower button most, please.
