Antenna Control for Near Field Communication Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing near field communication systems fail to prevent unwanted communication when a tag reader is mistakenly brought into proximity with an unintended tag, leading to undesired information transmission or processes, particularly in configurations where different information types are transmitted based on tag positions.
Innovation Solution
An information processing device controls a plurality of antennas on a display device to be either in a communication state or a non-communication state, determining regions based on element images displayed on the screen, allowing only intended near field communication to occur by controlling specific antennas to be active or inactive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tag reader is activated when a tag is brought into proximity, then near field communication can be performed, but unwanted communication occurs when the tag reader is mistakenly brought into proximity to an unintended tag
Solution Approach 1:
The display region is divided into multiple regions, with each region associated with a specific antenna. The region determining section identifies which region the tag reader is positioned over, and the antenna control section activates only the corresponding antenna for that region. This segmentation prevents unwanted communication by ensuring that only the antenna corresponding to the intended tag position is activated, while other antennas remain inactive even if tags are present in their respective regions.
2Adaptability or versatility
If multiple antennas are activated for near field communication, then communication flexibility is improved, but the risk of mistaken communication with unintended tags increases
Solution Approach 1:
Each antenna is assigned to a specific region of the display, and the system activates only the antenna corresponding to the region where the tag reader is currently positioned. This local quality approach maintains communication flexibility by allowing different antennas to be activated depending on the tag reader's position, while simultaneously preventing mistaken communication by ensuring that only the locally appropriate antenna is active at any given time.

Function Achieved in This Case
This solution effectively prevents unwanted communication by ensuring that only intended near field communication takes place, even if a tag reader is mistakenly brought into proximity with an unintended tag, thereby reducing undesired information transmission or processes.
Implementation Method 1
a near field communication section which is provided on the display section so as to be stacked on the display section and which includes a plurality of antennas via each of which the external near field communication is performed
