Abstract: A method for positional analysis, comprising the steps of: receiving, from a user device, location information indicating a location of the user device; identifying a location of at least one reference target; determining at least one intended location of the user device by applying a structure model to the location of the, or each, reference target; determining a difference between the, or each, intended location and the location of the user device; determining a first result indicating whether the difference meets a threshold distance of a predefined threshold rule; determining a second result indicating whether the predefined threshold rule is satisfied based at least in part on the first result; and in response, communicating an instruction to the user device indicating that the predefined threshold rule is satisfied, and associated system and device.
