Some years ago, I seem to recall seeing various head-mounted displays for sale which advertised focal distances of 6 feet or whatever, referring to the effective distance your eyes would focus at rather than making them work to focus directly on something an inch in front of them. I suspect this is roughly what OP was intending to ask about. However, this mechanic is only relevant to stereoscopic or other 3D displays, not to the plain LED/LCD displays used by the vast majority of handheld devices. Also, putting the focal point "beyond" the device implies, at least to me, that the device uses a transparent display plate and projects an image onto the display which appears to exist in the space behind the device; I am not aware of any handheld devices with such a display, even just as a flat HUD. -- Dave Sherohman
