Image control method and device

An image control device, comprising:

• a memory;
• and
• a processor coupled to the memory, the processor configured to:
• receive, using a display device displaying a plurality of items of selection option information, a selection operation by a user of an item of the selection option information, and store, in a first storage section, the selected item of the selection option information in association with a timing at which the selection operation for the selection option information is received;
• detect, using a detection device, detection information indicating at least one of a state of an area at which the display device is disposed or a state of a user present in the area at which the display device is disposed, and store, in a second storage section, the detection information in association with time information indicating a time at which the detection information is detected;
• extract, from the second storage section, time information that is associated with detection information indicating that at least one of the area or the user is in a predetermined state;
• identify an item of the selection option information stored at the first storage section in association with a timing that corresponds to the extracted time information from the second storage section;
• associate a change timing with the identified item of the selection option information, and store the identified item of the selection option information and the associated change timing in a third storage section;
• determine whether the change timing of any of the plurality of items of the selection option information displayed on the display device has arrived, by referencing the third storage section:
• and
• display, on the display device, the item of the selection option information having the change timing associated therewith determined to have arrived, using a different display mode from that of other displayed items of the selection option information.

An image control system comprising:

• a first display device that displays a plurality of items of selection option information and receives a selection operation by a user of an item of the selection option information;
• a management device including:
• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• store, in a first storage section, the selected item of the selection option information in association with a timing at which the selection operation for the selection option information is received;
• detect, using a detection device, detection information indicating at least one of a state of an area at which the first display device is disposed or a state of a user present in the area at which the first display device is disposed, and store, in a second storage section, the detection information in association with time information indicating a time at which the detection information is detected;
• extract, from the second storage section, time information that is associated with detection information indicating that at least one of the area or the user is in a predetermined state;
• identify an item of the selection option information stored at the first storage section in association with a timing that corresponds to the extracted time information from the second storage section;
• associate a change timing with the identified item of the selection option information, and store the identified item of the selection option information and the associated change timing in a third storage section;
• and
• determine whether the change timing of any of the plurality of items of the selection option information displayed on the display device has arrived, by referencing the third storage section;
• and
• a first control device including:
• a memory;
• and
• a processor coupled to the memory of the first control device, the processor being configured to display, on the first display device, the item of selection option information having the change timing associated therewith determined by the management device to have arrived, using a different display mode from that of other displayed items of the selection option information.
