Electronic Device Biometric Output with Color-Coded Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices that measure biometric information, such as pulse rate, suffer from reliability issues due to improper wearing, leading to potential errors and user anxiety when unreliable information is displayed without clear indication of its reliability.
Innovation Solution
An electronic device that integrates a processor to calculate the reliability of biometric information and output it in a mode that correlates with the calculated reliability, using visual and vibrational cues to indicate both the biometric data and its reliability simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information is displayed without reliability indication, then the display is simple and clear, but the user cannot ascertain the reliability of the information leading to unnecessary anxiety
Solution Approach 1:
The patent applies color changes to indicate reliability levels of biometric information. Different colors represent different reliability degrees, allowing users to quickly assess information quality without complex displays. This resolves the contradiction by providing clear reliability indication through intuitive visual cues while maintaining display simplicity.
Solution Approach 2:
The patent adds a visual dimension (color) to the display output to encode reliability information. Instead of adding complex text or numerical reliability metrics, the solution uses color as an additional dimension to convey reliability, thereby providing comprehensive information without increasing operational complexity.
2Reliability
If reliability calculation and multi-mode output are implemented, then the reliability of biometric information can be ascertained, but the processing complexity increases
Solution Approach 1:
The patent changes the output parameter (color) based on the calculated reliability of biometric information. The processor calculates reliability and maps it to different color parameters for display. This approach provides comprehensive reliability information while keeping processing relatively simple by using straightforward parameter mapping rather than complex multi-step processing.
Data Source
AI summary
An electronic device includes a first outputter and a processor. The processor is configured to acquire biometric information that is information about a living body, calculate a reliability of the biometric information based on the acquired biometric information, and output the biometric information to the first outputter in an output mode associated with the calculated reliability.
