The position information receiving unit 110 is a processing unit that receives the position information transmitted by the IR transmitting units installed at various locations in the store using an IR receiver, writes it in the log-information storing unit 140 together with the date and time, and receives an IR number transmitted by the IR transmitting unit as the position information. FIG. 3 is a diagram showing a part of the layout of IR transmitting units in the store. In FIG. 3, “001”, “002”, etc. are IR numbers for identifying each IR transmitting unit, and in this layout, the IR transmitting units are disposed at equal intervals to the left and right of the aisle flanked by shelves along which the cart 70 passes.
For example, in the IR transmitting unit layout shown in FIG. 3, if the position information receiving unit 110 receives an IR number “002” after receiving an IR number “001”, the moving-direction determining unit 120 calculates the moving direction of the cart 70 as “001->002”.
For example, in the layout example of the IR transmitting unit shown in FIG. 3, the left side position information receiving unit a receives the IR number “001”, the right side position information receiving unit b receives the IR number “011”, and the moving direction calculation unit 120 calculates the moving direction of the cart 70 as “001->002”.
For example, in the IR transmitting unit layout shown in FIG. 3, the position information receiving unit 110 receives the IR number “002” 10 seconds after receiving the IR number “001”, and if the distance between the two IR transmitting units is 10 m, the moving speed calculation unit 130 calculates that the moving speed of the cart 70 is 10 m/10 sec=1 m/sec.
For example, the time at which the position information receiving unit 110 received IR number “001” is 14:30:00 on Oct. 12, 2006, and at this time, since there is only one position information, the moving direction and the moving speed are not calculated. The time at which the position information receiving unit 110 received IR number “002” is 14:30:10 on Oct. 12, 2006, and at this time, since the IR numbers were “001” and “002”, the moving direction is “001->002”, and the moving speed is calculated to be “1 m/sec”.
The display control unit 150 performs control such that, if the moving speed exceeds a predetermined danger speed (>threshold speed), the warning “Please Do Not Run in the Store” is displayed.
FIG. 7 is a diagram showing the relation between moving speeds and displayed messages. As shown in FIG. 7, when the cart 70 receives the IR number “001” at a point PA, since at this stage the moving speed of the cart 70 cannot be calculated, the display control unit 150 displays “Message 2” which is information registered as a low speed message for the IR number “001”.
When the cart 70 receives the IR number “002” at a point PB, the moving speed calculation unit 130 calculates a transit time TA-B between PA and PB, and calculates the moving speed VA-B of the cart 70 from a position information transmitting unit interval I and TA-B. The moving speed calculation unit 130 manages the position information transmitting unit interval I using a table. The display control unit 150 compares the moving speed VA-B with a predetermined threshold speed (cart low speed threshold VSLOW), and if it does not exceed VSLOW, it displays “Message 3” which is information registered as a low speed message for IR number “002”.
On the other hand, if it exceeds VSLOW, the display control unit 150 compares the moving speed VA-B with a predetermined danger speed (cart high speed threshold VHIGH) If it does not exceed VHIGH, it displays “Message 4” which is information registered as a high speed message for IR number “002,” but if it exceeds VHIGH, it displays a warning.
FIG. 8 is a diagram showing an example of threshold speeds. In this example, a speed of “less than 0.75 m/sec” is taken as a speed at which the shopper does his shopping while looking at the products in the store, a speed of “0.75 m/sec to 1.75 m/sec” is taken as a speed at which the shopper moves to the next sales floor area, and a speed of “1.75 m/sec or more” is taken as a danger speed. All these thresholds speeds can be set to proper values. The position information transmitting unit interval I is 3 meters, a position information transmitting unit arrival distance r is 1.5 meters, the cart low speed threshold VSLOW is 0.75 meter/second, and the cart high speed threshold VHIGH is 1.75 meter/second.
For example, in the IR transmitting unit layout shown in FIG. 3, when the cart 70 is moving from the position of IR number “002” in the direction “001->002”, if the moving speed does not exceed the predetermined threshold speed, “Message 3” which is information about products near IR number “003” is displayed, and if the moving speed exceeds the predetermined threshold speed, “Message 4” which is information about products near IR number “004” is displayed.
The warning-display-instruction receiving unit 180 is a processing unit that receives warning display instructions transmitted by the store server 200, and issues an instruction to display a warning on the display control unit 150. The store server 200, when the cart 70 moving at higher than the danger speed is approached by another cart 70 from the opposite direction which is also moving at higher than the danger speed, issues an instruction to display the warning “Beware of Collision” on both of the carts 70.
As a result, if the moving speed does not exceed the predetermined threshold speed, namely, when the moving speed is a low speed, the display control unit 150 reads and displays a low speed message corresponding to the IR number in the newest log information from the message storing unit 160, and the moving direction (step S105). When the moving speed exceeds the predetermined threshold speed (i.e., when the moving speed is a high speed), the display control unit 150 reads and displays a high speed message corresponding to the IR number in the newest log information from the message storing unit 160, and the moving direction (step S106). If the moving speed exceeds the predetermined danger speed, the display control unit 150 displays “Please Do Not Run in the Store” as a warning (Step S107).
