Line-of-sight-based content-sharing dynamic ad-hoc networks

A wearable device, associated with a user being a member of at least one communicating group of users with respective wearable devices, the wearable device comprising:

• a position and orientation (P&O) module which receives or derives a position of the wearable device, and calculates:
• a device axis orientation of the wearable device with respect to an axis of a reference frame, and
• a line of sight (LOS) of at least one component with specified P&O, associated with the wearable device, the LOS calculation being carried out with respect to a scene, and based on the calculated device axis orientation of the wearable device and on the specified P&O of the at least one component, and
• a communication module which delivers specified data to at least one other wearable device of a respective at least one other user of the at least one communicating group,
• wherein the communication module delivers the specified data conditionally upon predefined rules and entering of the LOS of at least one of the other wearable devices to a region that was previously or is currently covered by a sector defined by a specified angle with respect to the calculated LOS and/or by a specified distance with respect to a position of the wearable device, and
• wherein said specified angle and/or said specified distance defining said sector are dynamically adjustable the calculated LOS and predefined rules.
