5 . The registration device according to claim 4 , further comprising:
a display configured to display an error screen when the warning signal is issued.
6 . The registration device according to claim 4 , further comprising:
a speaker configured to output a sound when the warning signal is issued.
7 . The registration device according to claim 1 , further comprising:
one or more wheels attached under the shelf.
8 . The registration device according to claim 1 , further comprising:
an input device through which identification information about the customer can be input.
9 . The registration device according to claim 1 , further comprising:
a projector configured to project an image on a floor, the image indicating an area including the first and second areas.
10 . The registration device according to claim 1 , further comprising:
a handle on each of side surfaces of the shelf.
11 . A method carried out by a registration device for registering a commodity to be purchased by a customer, the method comprising:
capturing an image of a first area and a second area outside the first area;
starting tracking of a customer who has entered the second area from outside the first and second areas based on the captured image;
determining whether a commodity is taken from a shelf based on changes in weight measured by a sensor;
upon determining that the commodity has been taken, determining whether the tracked customer has performed a particular action within the first area;
upon determining that the tracked customer has performed the particular action, determining whether the customer has entered the second area; and
upon determining that the customer has entered the second area from the first area, registering the taken commodity as a commodity being purchased by the customer.
12 . The method according to claim 11 , further comprising:
identifying the customer as a registered customer of a store based on the image captured by the camera.
13 . The method according to claim 12 , further comprising:
performing settlement processing on the taken commodity when the identified customer enters the second area from the first area.
14 . The method according to claim 11 , further comprising:
upon determining that a customer who is not being tracked performs the particular action, issuing a warning signal.
15 . The method according to claim 14 , further comprising:
displaying an error screen on a display when the warning signal is issued.
16 . The method according to claim 14 , further comprising:
outputting a sound when the warning signal is issued.
17 . The method according to claim 11 , wherein one or more wheels are attached under the shelf.
18 . The method according to claim 11 , further comprising:
receiving identification information about the customer via an input device.
19 . The method according to claim 11 , further comprising:
projecting an image on a floor, the image indicating an area including the first and second areas.
20 . A non-transitory computer readable medium storing a program causing a computer to execute a method for registering a commodity to be purchased by a customer, the method comprising:
capturing an image of a first area and a second area outside the first area;
starting tracking of a customer who has entered the second area from outside the first and second areas based on the captured image;
determining whether a commodity is taken from a shelf based on changes in weight measured by a sensor;
upon determining that the commodity has been taken, determining whether the tracked customer has performed a particular action within the first area;
upon determining that the tracked customer has performed the particular action, determining whether the customer has entered the second area from the first area; and
upon determining that the customer has entered the second area from the first area, registering the taken commodity as a commodity being purchased by the customer.
