depth perception
the experience of perceiving a third dimension of depth into a computer screen. For instance, windows add a certain depth by having shadows, and buttons indicate their dimensionality by having beveled edges.
Many different graphical qualities can act as depth cues, including:
- size: larger objects are perceived as closer than smaller ones
- texture: larger textures are perceived as closer than smaller ones
- occlusion: objects that block other objects are perceived as closer
- focus: sharply-defined objects are perceived as closer than blurred ones
- saturation: high-saturation colors are perceived as closer than low-saturation colors
