Motion parallax on a 2D display?
Can a window on a computer monitor look like a real window?
There has been a lot of discussion about the sense of immersion produced when viewing High Fidelity with Head Mounted Displays (HMDs). There may be a way to increase the sense of immersion when viewing High Fidelity on a standard 2D computer monitor.
What if the High Fidelity Interface on a computer monitor could act like a window into another world? At present, it looks like more the video display from a security camera in another world. You can move the camera around, and point it in various directions. It gives a view of the 3D world of High Fidelity, but it doesn’t make you feel that you’re actually there in that world.
When you look through a real window, you lean a bit to the left to see things off to the right, or you lean to the right to see things off to the left. As you lean back and forth, the apparent shift in position of the objects outside the window allow you to determine their relative positions through motion parallax.
HMDs produce 3D perception by using stereopsis (each eye receiving a slightly different view) and motion parallax (altering the view based on the position of the head). Stereopsis probably can’t be produced on a standard computer monitor. Motion parallax, on the other hand can be produced on a computer monitor if:
1) the monitor is being used by only one person at a time, and
2) the position of that person’s head can be tracked.
The High Fidelity Interface already offers face tracking. Could this face tracking data be used to control the camera position and direction, to allow motion parallax? This might result in a vast increase in the sense of immersion when visiting a High Fidelity space with only a standard computer monitor.
