Body relative direction

"Upright" redirects here. For other uses, see Upright (disambiguation).

Body relative directions (also known as egocentric coordinates) are geometrical directions relative to a body such as a human person's body or a road sign.

The most common ones are: left and right; forward and backward; up and down. These six directions form three pairs of orthogonal coordinate axes (the two horizontal coordinate axes left-right and forward-backward and the vertical coordinate axis up-down).
