This disclosure proposed the idea of applying a rules based policy to determining grouping by velocity and position. Specifically, a method to define a policy that influences how objects with similar velocity are grouped.

Method to use Velocity information to group devices

How can someone usefully group people using local information from their mobile devices? Proximity is not enough to determine association, so other methods must be used. As one method, history of proximity (such as, these individuals have a history of being within 10 feet of each other) may be used. But this does not help to determine subgroups within the group. For instance, two people may have a history of colocation due to working in adjacent cubicles, but may be total strangers. Additional factors such as communications (history of text exchanges or phone calls), similar physical characteristics (gender or age), interests (hobbies, job, education) or even positive confirmation of a relationship may be recorded and used.

This is especially vexing given the dynamic nature of groups and subgroups. As an example, take a group of people who are attending an event and will travel to and from the event in a convoy of vehicles (each vehicle containing a subgroup of the larger group). It is important, yet difficult, to determine who is riding with whom. Furthermore, these subgroups may change dynamically(passengers switch vehicles during rest stops) and each subgroup may deviate from an expected behavior (get lost, take an alternate route, stop for unforeseen reasons). Knowing the composition and location of these subgroups provides advantages -- they can account for all members, and in case of a change in route or conditions, the ability to send messages to multiple members of that subgroup can provide redundant routes of communication (example: A driver may not answer a call or read a text sent, but a passenger or passengers would) to increase the chance of successful receipt of the message.

This invention is an application that combines velocity and position information (and historical velocity and position) to dynamically determine the composition and status of these subgroups with a higher reliability. So within a group of 100 people, if they are within 10 feet of each other and travelling at 2 miles per hour, they may or may not be be part of the same subgroup. If they are within 20 feet of each other and travelling at 60 miles per hour, the chance that they are part of the same subgroup (in the same vehicle or bus) is quite high. When historical velocity is added in as a factor, the probability increases. That is, two vehicles may be within 20 feet of each other, at the same speed, and thus it may appear that the occupants of the two vehicles share the same subgroup. Yet it is very unlikely that the two vehicles will maintain the same close proximity and...
