Abstract: In a cart terminal device, a goods-layout-information storage unit stores goods layout information, having information indicating a layout region within a shop related to a goods classification indicating goods laid out in the layout region, and a contents-position-information storage unit stores contents position information, having a transmitter number related to the goods classification. When a user assigns an optional position and an optional transmitter within the shop, a transmitter-position-information creating unit obtains a goods classification corresponding to the position by referencing the goods layout information, and obtains a goods classification corresponding to the transmitter by referencing the contents position information. When the obtained goods classifications coincide with each other, the transmitter-position-information creating unit creates transmitter position information, having position information related to a transmitter number for identifying the transmitter.

Abstract: A movement information determining unit determines a moving direction and a moving speed of a user using position information detected by a position information detecting unit. A moving-speed determining unit determines whether the moving speed exceeds a predetermined threshold speed. An information display unit displays high-speed movement information corresponding to the position information and the moving direction when the moving speed is determined to exceed the threshold speed, and low-speed movement information corresponding to the position information and the moving direction when the moving speed is determined not to exceed the threshold speed.
