System for determining user interactions with items on a fixture

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.
