Abstract
Fixtures can hold one or more items. Load cells may be used to measure the weight of the items on the fixture. In cases where items are added to or removed from the fixture, the load cells will detect a weight change at the fixture. Data reflecting the weight change is then used to determine interactions with the items on the fixture. However, vibrations to the fixture can introduce noise which can lead to inaccuracies in weight data acquired from the load cells. A vibration sensor can be used to measure the level of vibration detected at the fixture. Weight data acquired during a time interval when vibrations exceed a vibration threshold value is deemed invalid weight data. By contrast, weight data acquired when vibrations do not exceed the vibration threshold value will be deemed valid weight data that can be used for determining interactions with items at the fixture.
