Summary of different methods of depth perception
| System of depth perception | Substrate |
| Binocular stereopsis/stereoacuity | Horizontal retinal image disparity |
| Motion parallax | Changing relations between objects with observer movement |
| Retinal image size | Increasing retinal image size with decreased viewing distance |
| Apparent size of similar objects | |
| Overlapping contours | The amount of tarmac between the car in front |
| Concealment of distant objects with near objects | |
| Brightness | Lights and shadows |
| Increased brightness with reduced viewing distance | |
| Aerial perspective | Distant objects appear indistinct and desaturated as a result of dust, haze, and smog |
| Convergence and accommodation | Increased convergence and accommodation with reduced viewing distance |
