I have been experimenting with using 5 phases of movements with each phase covering different areas of the screen while being actively moving. The last phase makes the dot move in a Lissajous-like motion which is more fluid like you are suggesting.

The challenge is recording and syncing the motion at a higher frequency and being able to save without much drift and the performance of these landmark/gaze models is often slow.

One more option to speed it up is not to do the eye tracking at record time, just record a crop video of the face and the screen first at 60Hz and then run the model on each frame and update the metadata of the dataset.
