The IntegraMouse + is a mouth-operated joystick operated that can be used for general PC access by acting as a mouse or joystick. As an additional feature, it is compatible with the Xbox Adaptive Controller (XAC) to act as left or right joystick on Xbox One or Windows 10 PCs.
To set up the IntegraMouse + with the Xbox Adaptive Controller, it must be put into ‘Joystick Mode’ (labelled J on the IntegraMouse +). This can be done by using either the sip/puff function of the IntegraMouse + or an external switch to plug into the 3.5mm jack. A blue light will be lit up next to the ‘J’ to confirm it is in ‘Joystick Mode’. The IntegraMouse + is now ready to be used with the Xbox Adaptive Controller.
