1. System comprising a display rack (1), wherein the display rack comprises multiple shelves (2′, 2″, 2″″, 2″″) and a base (4) for supporting the shelves, wherein each of the shelves comprises a sensor mat (5) comprising a lattice of load sensors, wherein the base is configured for measuring a total weight, wherein the total weight includes weights of any objects positioned on the shelves, wherein, the system is configured for determining object addition or removal event data based on in time corresponding changes of:
total weight measured at the base; and
binary load status of multiple load sensors of a sensor mat of the display rack,
wherein a binary load status of a load sensor indicates whether the load sensor at least in part supports an object or not,
wherein the object addition or removal event data comprises:
an object weight based on said change of total weight measured at the base; and
an object support shape and an object location both based on said change of binary load status of multiple load sensors of said sensor mat of the display rack,
wherein the base comprises a base plate (6) comprising multiple weight sensors (7) for supporting the shelves, wherein the display rack is configured for determining a total weight based on signals from each of said weight sensors
wherein the shelves comprise a first shelf (2″″), wherein the display rack comprises base support elements (8″″), wherein each base support element is connected (9″″) to the base plate (6) and slideably attached (10″″) to the first shelf, wherein the base plate is configured for supporting the base support elements via the weight sensors; and
wherein the base support elements are telescopically extendable.
