Abstract
A user undertakes an event, such as adding, removing, or otherwise interacting with an item stowed at a fixture. Using successive samples of weight data that occur during an event, a plurality of vectors are generated that are indicative of a weight change and a location associated with the fixture. The vectors are processed to determine where within the fixture the event took place. Hypotheses are generated that describe predicted interactions involving predicted locations that correspond to those indicated by the vectors. The hypotheses are ranked and then one is selected as a solution. The predicted values associated with the selected hypothesis are then used to generate interaction data that indicates one or more types of item and quantities of the items that were added, removed, or otherwise handled by the user.
