There was at least TrackIR providing that back then https://en.m.wikipedia.org/wiki/TrackIR https://en.m.wikipedia.org/wiki/TrackIR I remember having tried on plane simulators back then and, even if it was cool as a technology, it wasn't really useful on a computer as you simply don't move your eyes and head enough. If you do, the screen is out of your field of vision. For this to work well, the screen would either need to be massive and curved or move as you move your head.
