Hi @arkanuuu, the software we provide for the 4C known as “Tobii Eye Tracking Core Software” does not include gaze control of mouse but rather is designed to work alongside the mouse and keyboard by introducing features such as ‘mouse warp’ where the cursor is still controlled at a fine level by the mouse but on a course level by gaze location.
For 4C users, this can be download @ https://gaming.tobii.com/getstarted/ but I am afraid this software has not been tested or officially recognised to work with the Tobii Fusion.
You also have the option of using Eye Control directly within Windows 10 Fall Creators Update. Again, this is not full mouse emulation but perhaps will be of interest to you. Further details @ https://support.microsoft.com/en-gb/help/4043921/windows-10-get-started-eye-control
I am afraid that the use of the Fusion for Gaming or Windows Interaction is not its purpose so we cannot guarantee any functionality of this type if used with the interaction software, unfortunately.
