title_body: Alternate direction systems for spatial reference What are some alternative direction systems besides egocentric direction systems (left, right, &amp;c)?
  Some natural languages use {north, south, east, west} like Guugu Yimithirr and Tzeltal (Maya) (source for Tzeltal). The situation in Tzeltal is probably more complex, since there's references to an uphill/downhill distinction too, but I'm having trouble locating a free resource for it.
  Ithkuil uses the position of the sunrise and sunset. It does not appear to use the current position of the sun.
upvoted_answer: Okay. How about instead of an egocentric direction system, employing a listener-centric or &quot;you&quot;-centric system? We do this in natural language when we say &quot;On your left&quot; or &quot;At your 3:00&quot;. Probably such a system would be developed among speakers from a highly empathetic and listener-oriented culture, where the individual's reference is considered secondary to the listener's.
