Wireless Pairing Accuracy via Distance Measurement Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems often establish connections with unintended terminal apparatuses, leading to inaccurate pairing with the user's device, especially when multiple devices are present, causing undesired connections with devices that are simply close or closest to the processing apparatus rather than the actively operated one.
Innovation Solution
An information processing apparatus that measures distances to terminal apparatuses before and after a user's operation, determining which device has approached and remains within a close range, allowing for accurate pairing with the user's terminal apparatus through a processor-controlled method using threshold values and timing criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If connection is established with the terminal apparatus closest to the processing apparatus, then connection speed is improved, but connection accuracy deteriorates (connecting with wrong device)
Solution Approach 1:
The system performs preliminary actions by measuring distances multiple times during a first period before the user operation to establish baseline positions of terminal apparatuses. This preliminary distance measurement allows the system to distinguish between terminals that are merely close versus those that are actively approached by the user, resolving the contradiction by preparing accurate identification data before connection is attempted.
Solution Approach 2:
The system implements feedback by continuously monitoring distance changes during both the first period (before user operation) and second period (after user operation). By comparing distance measurements across these periods and detecting approach behavior, the system receives feedback about which terminal is being actively approached, enabling accurate connection selection while maintaining fast connection speed.
2Ease of operation
If automatic connection is implemented without user intervention, then ease of operation is improved, but reliability deteriorates (undesired connections)
Solution Approach 1:
The system performs preliminary distance measurements during the first period before the user operation to establish which terminal apparatuses are present and their positions. This preliminary information gathering enables the system to make reliable automatic connection decisions based on objective approach detection, rather than random or purely proximity-based selection, thus maintaining both ease of operation and connection reliability.
Solution Approach 2:
The system implements self-service by automatically detecting which terminal apparatus is being approached by the user through distance measurement analysis and establishing connection without requiring user intervention. The system serves itself by using its own sensing capabilities to identify the correct terminal, eliminating the need for manual selection while ensuring reliable connections through objective approach detection.

AI summary
An information processing apparatus includes a processor configured to measure a distance to a terminal apparatus around the information processing apparatus plural times during a first period before receipt of an operation of a user and during a second period after the receipt of the operation, and establish connection for wireless communication with the terminal apparatus in a case where the measured distances indicate that the terminal apparatus has approached the information processing apparatus during the first period and is within a close range from the information processing apparatus during the second period.
