Abstract: A surface within a facility, such as a floor, is equipped with electromagnetic sensors that generate data indicative of the presence of objects, such as the feet of users, at or close to the floor. The data may also be indicative of cross-coupling resulting from a transfer of an electromagnetic signal by the object, such as from one foot to another of a user. The data is processed to determine presence of individual object representations, such as representing a foot. Information about object representations such as their movement, cross-coupling, physical distance between, or features of the object representation may be determined. This data may be used to maintain the identity of particular object representations, track object representations over time, determine that particular object representations are associated with a single user and so forth. Adjacent object representations may avoid merging by using a top-down cross sectioning technique.

Abstract: A floor device generates output data indicative of the presence of objects, such as feet of users, on the floor device. The output data from the floor device is processed to determine an object representation at a given time. The object representation may then be associated with a user identifier based on characteristics or features of the object representation. If a location of a user associated with the user identifier is determined to be near a fixture that stores one or more items, changes in quantity of items at the fixture may be associated with the user. For example, sensors on the fixture may generate fixture data indicative of a pick or place of items on the fixture. Based on the location of the user being near the fixture and the fixture data, interaction data may be generated indicating the user interacting with the items at the fixture.
