Abstract
An apparatus for use at an inventory location stowing items comprises an array of sensor elements. Each sensor element comprises a plurality of conductive elements that may be driven as a self-capacitance sensor. A set of one or more sensor elements may be associated with a particular lane. Based on the changes in self-capacitance values and the association, the lane a user interacted with may be determined. The determination of the set of sensor elements associated with a particular lane may be determined during a setup process. During operation, the conductive elements may be driven to compensate for changes in the self-capacitance resulting from temperature changes resulting from changes in ambient temperature or the items. Compensated capacitance data may be used to determine interaction data, count of items in the lane, and so forth. Sensor elements at one or both ends of a lane may be used to disambiguate interactions.
