Abstract: An indoor location is mapped into a grid comprising grid cells, each cell associated with items or objects detected as being present in the corresponding cell. The grid, grid cells, and linked items and/or objects are generated and updated using an Augmented Reality (AR) algorithm that maps a physical environment into cells and measures distances and directions within the environment relative to each cell. Walking paths (routes) to the items within the indoor location are generated using the grid information. As a user walks a path, the user's position within the indoor location is mapped and tracked to the cells and the path revised based on the user's actual position. A user device provides video via an AR application to track the user's position; a rendering of the position and path are superimposed within the video being viewed by the user on the user-operated device.

Abstract: Embodiments described herein are directed to tracking objects using a cognitive heterogeneous ad hoc mesh network. A first participant receives a notification signal from a second participant. The first participant determines first positioning information from the notification signal and second positioning information from characteristics of the received signal. If the difference between the first and second positioning information is below a first threshold, then the second participant is within line-of-sight of the first participant. If the difference is above the first threshold and below a second threshold, then the second participant may have a malfunctioning sensor. But if the difference is above the second threshold, then the second participant is not within line-of-sight of the first participant and the received signal was reflected off another object. The positioning information can then be refined or transmitted to other participants.
