Obviously, there is little interest drawn to direction awareness compared to location awareness. It is weird since information about direction could be of interest in numerous contexts. Perhaps direction-based information could be a way to add value to location-based services : the next big thing ?
In both my literature reviews about both socio-cognitive roles of space and awareness tool, I found no paper concerning the topic of direction. However, direction is closely related to position since it is possible to calculate a direction thanks to the two last positions .
