Title:
POSITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/139003
Kind Code:
A1
Abstract:
The present invention relates to a positioning device, comprising a main terminal and a plurality of sub-terminals which wirelessly communicate with the main terminal in a certain distance range. The main terminal comprises a plurality of display units for indicating each sub-terminal, and each of the sub-terminals comprises a unit for outputting a warning sound output. When a sub-terminal is beyond a certain distance range from the main terminal, which is set so as to be maintained, the sub-terminal beyond the boundary of the said specific set distance range is immediately displayed on the main terminal, and a warning sound is outputted in the sub-terminal which is beyond the boundary of the specific set distance range. Accordingly, in a group outdoor activity (for example, a domestic/overseas trip, a hike, a picnic, etc.), a leader can easily recognize whether participants are within the boundary to prevent participants from deviating from the group gathering. In addition, a schedule for the group gathering, information on the schedule (for example, visiting tourist spots), and participant lists are stored in the main terminal and sub-terminals so as to be viewable, and thus the leader and participants can all easily obtain the schedule of the group activity, and also feel a greater sense of camaraderie by reading information on the other participants.
