In another example, an xR experience may warn a construction worker if they are digging too close to a live power line or sensitive equipment, if an action or plan violates a building code, if electrical is being placed too close to plumbing, etc.
In some cases, an xR system may identify distraction free zones and filter experiences accordingly. For examples, experiences may be filtered based on proximity to natural disasters (this is an example of time-based proximity). The xR system may also restrict or prohibit advertising in times crisis or ensure a focus on emergency messaging. The xR system may also be used to redirect traffic in the case of an emergency that impacts a traffic route, or trigger an emergency shutdown switch for systems that may be impacted by such an emergency.
Visibility of xR experiences may vary according to a location in space, a point in time, and who is observing. For example, if a child is nearby and observing an event, their experience may filter out content that is not appropriate for children. Hence, the definition of the xR object is based on space, time and proximity of person or even other non-person objects.
An xR system may utilize a wide spectrum of proximity-tracking technologies with varying degrees of precision that can help with identifying proximity. Examples include: GPS, Wi-Fi, beacons based on Bluetooth or other technology, carrier services, LIDAR, different cameras types, proximity sources and databases.
