We are definitely working on bringing eye tracking features to strategy games. So far we come up with the following features:
– Center@gaze / Bungee zoom https://tobii.github.io/UnitySDK/eyetracking-features#map-navigation
– Zoom at gaze – zoom towards your gaze instead of mouse pointer.
– Cast spell@gaze
Unfortunately, selecting units won’t work well since they are usually too small and grouped together.
In some cases it’s possible, like in Shadow Tactics where you can iterate enemy units in the gaze area by looking at them and pressing a button.
