Visualization of customer shopping-path using RFID techniques

Abstract

Recently, RFID techniques enable us to obtain enormous amount of information on positions of humans and objects in a building. This paper discusses the visualization method of customer shopping-paths in a Super-Market that are obtained by RFID techniques. For this, two different methods are applied to visualize the customer shopping-paths, which are Kernel Density Estimation method and Vector Field Visualization. By applying the Kernel Density Estimation method, it helps us to visually understand the customer existence probability density in sales floor, whereas the Vector Field Visualization enables us to grasp the customers' flow.
