Location-Aware Media Player Selection via Signal Profile Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices require users to manually search and select Digital Media Players or Renderers within a local network to share media content, which is inconvenient, especially when the user moves to a different location, as they need to reset the playback device each time.
Innovation Solution
A location-aware method and device that uses a signal detecting module to automatically select a peripheral player by comparing detected signal sources and strengths with pre-recorded system profiles, allowing for seamless media content sharing without repetitive user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual search and selection of Digital Media Players is implemented, then device compatibility and network control are improved, but user operation convenience deteriorates
Solution Approach 1:
The system pre-establishes location information and associated media player configurations in advance. When a user moves to a location, the system automatically retrieves and applies the pre-configured player settings for that location, eliminating the need for manual search and selection while ensuring compatible device connection.
Solution Approach 2:
The system automatically detects user location through signal strength measurement and autonomously selects and configures the appropriate Digital Media Player without requiring user intervention. The system serves itself by matching location data with pre-configured player profiles and executing the corresponding settings automatically.
2Reliability
If manual device selection is required at each location, then precise device control is improved, but time efficiency deteriorates
Solution Approach 1:
Location-specific media player configurations are established in advance during system setup. When the user arrives at a location, the system automatically retrieves the pre-configured player settings for that specific location, ensuring precise device control while eliminating the time-consuming manual selection process.
Solution Approach 2:
The system continuously monitors signal strength and location information, providing feedback to automatically determine which Digital Media Player should be active. This feedback mechanism ensures the correct device is selected based on current location while maintaining precise control over media playback.
3Ease of operation
If location-aware automatic selection is implemented, then user operation convenience is improved, but system complexity increases
Solution Approach 1:
Location information serves as an intermediary that connects the user to the appropriate Digital Media Player. The system uses location data as a key to automatically retrieve and apply the correct player configuration, simplifying user interaction while managing system complexity through structured data organization.
4Measurement precision
If signal detection and profile matching is implemented, then automatic device selection accuracy is improved, but processing time increases
Solution Approach 1:
Signal strength thresholds and device matching criteria are pre-calculated and stored during system configuration. When location detection occurs, the system compares current signal measurements against pre-established profiles using predetermined matching algorithms, ensuring accurate device selection while minimizing processing time through预先 prepared reference data.
Data Source
AI summary
A method, a mobile device, and a computer-readable recording medium for a location-aware application are provided. In the method, at least one signal source around the mobile device and a signal strength thereof are detected by using a signal detecting module. Then, each detected signal source and the signal strength thereof are compared with a signal source and a signal strength thereof recorded in multiple system profiles, so as to find a system profile having matched signal source and signal strength, in which the system profiles include signal sources and signal strengths thereof which are recorded and detected by the mobile device at multiple different locations and a system setting of the mobile device applicable to each location. Finally, a system setting of a matched system profile is executed.
