Solution Overview
Problem
Conventional techniques lack specific control mechanisms for handling changes in detection targets detected through short-range communication, particularly when multiple targets are proximate to each other, and fail to execute processes associated with these changes.
Innovation Solution
A control device connected to a detection device with multiple detecting sections, which obtains and analyzes the locations of detection targets over time, determines movement or proximity of targets, and executes processes based on these determinations, including displaying information relevant to the state of the targets.

Engineering Contradiction Analysis
1Quantity of substance
If multiple detection targets are detected through short range communication, then the system can identify multiple objects (e.g., users), but the conventional techniques fail to execute specific control processes for each case
Solution Approach 1:
The patent divides the detection area into multiple regions (first region, second region, third region) corresponding to different users or detection targets. Each region has specific NFC antennas assigned to it, allowing the system to independently identify and process each detection target. This segmentation enables the system to handle multiple objects simultaneously while executing specific control processes for each region, resolving the contradiction between detecting multiple targets and providing adaptive control.
2Loss of information
If the system displays information for multiple detection targets in separate regions, then location-specific information can be provided, but no specific control is executed based on the state changes of detection targets
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the state of detection targets (such as whether an NFC tag is detected or not) and automatically executes control processes based on state changes. For example, when a detection target moves from one region to another or when the presence/absence of NFC tags changes, the system receives feedback about these changes and automatically adjusts the display content and control actions accordingly. This feedback loop enables automatic control execution while maintaining location-specific information display.
3Device complexity
If conventional techniques only display information without executing specific control processes, then the system is simpler to implement, but it cannot respond to state changes of detection targets
Solution Approach 1:
The patent introduces dynamic control mechanisms that automatically adjust system behavior based on real-time detection results. The control device executes different processes depending on the state of detection targets, such as displaying different information when NFC tags are present or absent, or when detection targets move between regions. This dynamic adaptation allows the system to respond to state changes without requiring complex manual intervention, achieving versatility while maintaining reasonable system complexity through automated decision-making algorithms.

AI summary
A predetermined process is executed in accordance with a state of a detection target which has been detected through short range communication with the detection target. In a case where a control device (100) has determined that a location of an NFC tag (30) detected by a display device (10) had changed, the control device (100) causes the display device (10) to transmit predetermined information to the communication terminal (20) via an NFC antenna (11).
