In one aspect, a method of classifying a plurality of objects includes receiving, from a sensor mat, a pressure indication and a capacitance indication, corresponding to the plurality of objects placed on the sensor mat. The method includes determining an object location for each object from the plurality of objects from the pressure and/or capacitance indication. The method includes determining an object profile which includes an object pressure profile and an object capacitance profile for each object. The method includes determining, by one or more processors, the identity of a first object based on a correlation of the determined object profile matching with a first stored object profile from a plurality of first stored object profiles in a data store. The method includes performing at least one action based on the determined identity of the first object.
