im not sure how the 3ds did it but if this is what I think the screen will still require physical lines to work off of that will be so thing that they should barely be visible or assuming its done better two screens on top of each other where the first screen throws up the lines and could likely be something like eink.

that is sad to hear. when it was coming in I just assumed it would be something eventually all cards had as standard.

this was working well in a research lab in the aughts. Surprised its not more common as by now I would think any laptop camera should be able to do eye tracking pretty decently.
