4. Interaction Modes

There are 3 interaction modes in our software: Fullscreen, fixed window and the touchpad-like mode.

3.1. The Fullscreen Mode

The fullscreen mode simply maps the four crosses to the four corners of the screen, however, this mode doesn't have a very good precision.

3.2. The Fixed Window Mode

Another option is using the fixed window mode to map the four crosses to the four corners of some portion of the screen, delimited by a dotted rectangle. This rectangle may be moved using the mouse, and the size of the rectangle can be made custom editing the mouse range field.

3.3. The Touchpad-Like Mode

Finally, for those who don't like having to switch between the pen and the mouse all the time, there is the touchpad-like mode, where one may move the dotted rectangle also with the pen, by raising it above the level where the program can track its shadow and returning in another position, as with a touchpad from a laptop computer. However, this mode is harder to control and might not be very stable when the tracking conditions are bad.
