External Device Search Priority for Faster Connection Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting external devices to electronic devices, such as personal computers, often require users to wait for extensive searches of all interfaces before presenting high-priority devices, reducing operability and productivity.
Innovation Solution
An electronic device that immediately presents a high-priority external device upon discovery and displays a search-in-progress screen during secondary searches, ensuring users can connect to high-priority devices without waiting for lower-priority searches to complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device waits for the search of all interfaces to complete before presenting external devices to the user, then all external devices including high-priority ones can be found, but the user experience deteriorates due to excessive waiting time
Solution Approach 1:
The system performs preliminary search actions on high-priority interfaces first, presenting found devices to the user before completing searches on lower-priority interfaces. This allows the user to connect to high-priority devices without waiting for the entire multi-interface search to complete, while still maintaining the option to search all interfaces if needed.
Solution Approach 2:
The search process is segmented into priority-based phases. High-priority interfaces are searched and presented first, then lower-priority interfaces are searched subsequently. This segmentation allows the system to provide immediate value to the user while continuing background searches, resolving the contradiction between completeness and speed.
2Productivity
If the electronic device presents external devices in sequence as they are found, then the user can quickly access devices, but there is a risk that users may select low-priority devices instead of high-priority ones
Solution Approach 1:
The system performs preliminary identification and prioritization of high-priority external devices before presenting them to the user. By pre-processing the search results to identify which devices should be presented first based on interface priority levels, the system ensures that users are guided toward the most appropriate devices while maintaining fast access.
Solution Approach 2:
The system provides feedback to the user about device priority and search status. By indicating which devices are high-priority and continuing to search for additional devices in the background, the system helps users make informed decisions about which devices to connect to, improving selection accuracy without sacrificing connection speed.
3Measurement precision
If the electronic device displays a search-in-progress screen until all interface searches are complete, then no high-priority devices are missed, but operability deteriorates due to forced waiting
Solution Approach 1:
The search-in-progress screen is made dynamic by allowing it to transition to device presentation screens when high-priority devices are found, while continuing background searches. The interface adapts its state based on search results, providing immediate interactivity for high-priority devices while maintaining the option to discover additional devices, thus improving operability without sacrificing completeness.

AI summary
An electronic device is controlled such that a search-in-progress screen is displayed when search is started by the search unit. The electronic device is controlled such that, in a case where a first external device is found by search using a first method and a predetermined condition regarding a first access point to be connected with the electronic device is satisfied, a first screen for connecting to the first external device is displayed before elapse of a predetermined time since the start of the search, without setting the second external device as a candidate for a connection destination. The electronic device is controlled such that, even if the second external device is found by a second method, a second screen indicating that search is in progress is displayed at least until the elapse of the predetermined time, unless a user operation is performed.
