Abstract: Methods, systems and wearable devices are provided, which are associated with users in communicating group(s). Devices receive or derive their position, calculate their device axis orientation with respect to an axis of a reference frame and a line of sight (LOS) of associated component(s) or user, and deliver specified data to other users according to their position with respect to the LOS and predefined rules.
