NFC Terminal Position Tracking via Touch Panel Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Near Field Communication (NFC) displays struggle to recognize the location of an NFC terminal after it has been moved and are limited in the range of movement for process selection, failing to effectively link communication information with position information.
Innovation Solution
An information processing device that includes a terminal information acquisition unit, a position information acquisition unit, and an association unit to acquire and associate terminal information and position information via Near Field Radio Communication, enabling processes to be performed by linking communication information with the client device's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If NFC communication is performed with a client device, then terminal information can be acquired, but the display cannot recognize the location of the NFC terminal when it is moved
Solution Approach 1:
The patent combines NFC communication information with touch panel position information into a unified data structure. The association unit merges terminal information acquired through NFC with position information from the touch panel, creating comprehensive tracking data that maintains both communication details and location data even when the device is moved.
Solution Approach 2:
The system continuously monitors and updates the position of the client device on the touch panel as it moves. The association unit receives ongoing position information and updates the stored association between terminal information and position information, providing continuous feedback about the device's location throughout the interaction.
2Adaptability or versatility
If the range of movement is limited for process selection, then process selection can be simplified, but the functionality is insufficient for performing processes by linking communication information with position information
Solution Approach 1:
The touch panel serves multiple functions: it acts as both the display interface and the position detection surface for NFC terminals. The same touch panel that displays information also detects the position and movement of the client device, eliminating the need for separate sensing hardware and reducing overall system complexity.
Solution Approach 2:
The system uses the existing touch panel infrastructure to provide position detection functionality. The touch panel's inherent ability to detect touch and position is leveraged to track NFC terminal movement, allowing the system to serve multiple purposes with existing components rather than requiring additional specialized hardware.
3Measurement precision
If position information is continuously tracked, then location recognition is improved, but information processing complexity increases
Solution Approach 1:
The association unit is pre-configured to automatically associate terminal information with position information as the client device is placed on the touch panel. This preliminary association is established before movement occurs, and the system is set up to automatically update this association as position changes are detected, reducing the need for complex real-time processing decisions.

AI summary
A process is performed by linking communication information acquired by Near field radio communication from a client device with position information of the client device. An information processing device (1) includes an association unit (211) configured to: acquire via an NFC unit (112) configured to perform Near field radio communication, terminal information held by an NFC terminal; acquire touch information including information on a position on the touch panel (111), the NFC terminal coming into contact with the position; and associate the terminal information and the touch information and store a result of the association.
