Limiting joystick/cursor movement to pathways

Is there any simple way I could possibly limit the movement of the joystick &/or cursor to a certain pathway or shape like an upside-down T (see attached image). Thanks in advance for any help or ideas!

You can use the custom calibration function. See this manual page.

There is also an example task of this in the "task\runtime v1\8 customized calibration\" directory.

I wrote an example task for you. This example requires you to define the boundaries of the pathways with non-overlapping rectangles. See the code in the attached file.
