Abstract: A system and a method are provided for selecting a site for displaying information to a user in a geographical area including a plurality of sites at which information may be displayed. Position, orientation and optionally gaze direction data are received from headsets worn by a plurality of users in the geographical area. The data is analyzed to determine for each site a probability of the site being viewed by users in said geographical area. A request is received for a selection of a site at which to display information to a particular user wearing a headset. The request identifies the headset and includes position of said particular user. In response to a request, a site is selected based on the analysis and signal identifying the selected site is output.

Abstract: A system for tracking wearable user devices is provided herein. The system may include a tracking environment, comprising: one or more scene light sources, wherein the location of the scene light sources is known within said tracking environment; one or more scene detectors operable to detect light within the tracking environment, wherein the location and orientation of said one or more scene detectors is known within said tracking environment; one or more scene reflectors operable to reflect light originating from said one or more scene light sources, wherein the location of said one or more scene reflectors is known within said tracking environment; and, one or more wearable user devices comprising a curved reflective surface with known geometry; and, a computer processor operable to analyse light readings detected by said one or more scene detectors, and to calculate a position of the one or more wearable user devices.

Abstract: A method of pedestrian navigation based on an external positioning system and a Dead Reckoning (DR) system, us provided.

Abstract: A method of pedestrian navigation, based on an external positioning system and a Dead Reckoning (DR) system, is provided herein. The method may employ the following steps: obtaining external positioning readings from an external positioning source and DR position readings from a pedestrian-carried platform; estimating an external positioning error, based at least partially on the external positioning and the DR position readings; and applying an estimation function to the external position readings, the DR position readings, and the external positioning errors, to yield a corrected estimated position.
