- sleepybrett 3y agoI remember a friend on a team adjacent to the surface table team talking about them trying to do this when they switched from projection tables to tables with screens in them. As I recall with the projector based tables (the ones that looked like old cocktail arcade tables) I think they were using an ir camera to detect items and touches on the 'screen'.
- raphman 3y agoYes, the original Surface tabletop used IR cameras. Its successor, the Samsung SUR40 had in-cell sensing, i.e. photosensors embedded into the LCD so that it could capture a 960x540 image of the table surface.
