FOV on HMD
Posted: Wed Jun 18, 2014 10:10 pm
Hi All,
Crazy thing that I'm wondering about.
If I understand correctly from what I have read so far (and I may not have seeing I'm new to this) one of the limiting factors that determine the FOV with a rift style HMD is due to the border where the left eye and right eye image meet. This pretty much determined the maximum distance the LCD screen can be and limits its FOV. If you would widen the FOV the left eye would start seeing part of the right eyes screen and visa versa.
But what if you would use a parallax filter to stop this from happening? Not too practical with an LCD screen but possible with an HMD where you use two picoprojectors that project the image on a screen. Each picoprojector would have a parallax barrier and each lens would have one to ensure the left eye sees the image the left projector produces and the right the right.
It would also mean the weight of the HMD could be concentrated to the sides of the HMD and a lightweight simply screen would take the place of a 'heavy' LCD.
Stupid idea?
Cheers,
