playing Disco Elysium with Tobii Windows Control
Atmospheric story driven game with some interesting social commentary. One of the best in its genre ever in my opinion. I would recommend for someone above 15 years though due to some of its themes and perhaps you should play something else if you're going through some difficult times yourself, or the opposite if you think sad movies and games could help you process difficulties. In any case this game gets to you and that's why it's such a masterpiece.
And very accessible, just mouse and click. Works really well with Tobii consumer eye trackers 4C, Eye tracker 5 together with the free software Gazepoint. You could use switch scanning and/or voice recognition just as well i imagine.
I use the paid assistive Dynavox Windows Control. And software Project Iris lets me blink when I wanna toggle Tab key, which isnt really necessary but that activates highlighting of every item you can interact with in the scene (i played it through the first without ever using this but I think I missed some items).
