Authentication Screen Display Timing for BLE Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User convenience is compromised during the pairing process between devices due to the need for user input and time-out settings in Bluetooth Low Energy (BLE) standard communication, particularly when devices lack a display function and require printing or have long output times for pairing information.
Innovation Solution
An information processing apparatus that confirms the completion of predetermined information output by a communication apparatus and displays a screen to initiate processing only after the output is confirmed, preventing premature authentication and ensuring user input is facilitated within the necessary time frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication apparatus prints authentication information and waits for user input, then user convenience is improved by providing sufficient time for input, but the processing time increases and time-out may occur
Solution Approach 1:
The information processing apparatus displays a message on the display unit before initiating authentication processing, informing the user that authentication information will be printed and providing advance notice. This preliminary action allows the user to prepare for the upcoming authentication process without experiencing time-outs, as the apparatus waits for the print completion before starting authentication.
Solution Approach 2:
The system provides feedback to the user by displaying a message that indicates authentication information is being printed and will be available soon. This feedback mechanism keeps the user informed about the processing status and manages expectations about the time required for authentication, preventing premature time-out while maintaining user convenience.
2Productivity
If the authentication processing starts immediately after printing instruction, then processing speed is improved, but user input cannot be facilitated within necessary time frame
Solution Approach 1:
The display unit displays a message before authentication processing starts, indicating that authentication information will be printed shortly. This preliminary display allows the system to maintain productivity by preparing the authentication flow while giving the user adequate time to receive and read the printed authentication information before the actual authentication begins.
Solution Approach 2:
The system dynamically adjusts the timing between printing authentication information and initiating authentication processing. Instead of a fixed immediate transition, the system waits for the print completion event to occur before starting authentication, creating a flexible timing mechanism that accommodates both speed and user input requirements.
3Reliability
If time-out time is set for user input, then authentication security is improved by preventing unauthorized access, but user convenience lowers due to potential time-outs
Solution Approach 1:
The system displays a preliminary message before authentication starts, informing users that authentication information will be printed and providing advance notice. This allows users to prepare for the authentication process knowing exactly what to expect, reducing anxiety about time-outs while maintaining security through proper authentication flow control.
Solution Approach 2:
By providing continuous feedback about the authentication status and print completion, the system helps users understand the current state of authentication processing. This feedback mechanism reduces unnecessary time-outs caused by user confusion while maintaining security by ensuring authentication only proceeds when appropriate conditions are met.

AI summary
An information processing apparatus confirms whether a communication apparatus has completed output of predetermined information used to execute predetermined processing between the information processing apparatus and the communication apparatus, and causes a display to display a screen used to start the predetermined processing based on confirming that the communication apparatus has completed the output of the predetermined information.
