  1. The pyglet graphics backend must be used; pygame is not supported.

  2. ioHub devices that report position data use the unit type defined by the PsychoPy® Window. However, position data is reported using the full screen area and size the window was created in. Therefore, for accurate window position reporting, the PsychoPy® window must be made full screen.

  3. On macOS, Assistive Device support must be enabled when using psychopy.iohub:
