Biometric Sensor Gesture Trigger and Skin Contact Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices face challenges in accurately and conveniently measuring biometric information in real-time, as they struggle to determine whether the current state is suitable for measurement and require specific applications to operate effectively.
Innovation Solution
An electronic device equipped with a first sensor module for detecting gestures and a second sensor module for measuring biometric information, which acquires first biometric information and determines if the user's skin contacts the module, allowing for the acquisition of second biometric information based on this determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a particular application is executed to measure biometric information, then measurement accuracy is improved, but measurement convenience deteriorates due to the requirement of specific application execution
Solution Approach 1:
The electronic device automatically detects gestures through the first sensor module and initiates biometric information measurement without requiring the user to manually open or execute a specific application. The processor autonomously determines whether to perform measurement based on detected gestures, making the system self-activating and eliminating the need for user intervention to start the measurement process.
2Productivity
If biometric information is measured continuously, then real-time monitoring capability is improved, but power consumption increases
Solution Approach 1:
Instead of continuous measurement, the system uses periodic action triggered by gesture detection. The processor monitors for specific gestures (such as picking up the device or specific hand movements) and only activates the biometric sensor module when these gestures are detected. This allows the system to maintain real-time monitoring capability while consuming power only when measurement is actually needed, rather than continuously.
3Speed
If the sensor module measures biometric information without determining contact state, then measurement speed is improved, but measurement reliability deteriorates
Solution Approach 1:
The system performs preliminary action by detecting gestures and determining skin contact state before initiating biometric information measurement. The processor first detects whether the user's skin is in contact with the sensor module through the first sensor module, and only then activates the second sensor module for measurement. This preliminary check ensures measurement reliability by confirming proper contact before measurement begins, while maintaining speed through automated gesture-based triggering.

AI summary
A method of operating an electronic device is provided. The method includes detecting a gesture through a first sensor module, acquiring first biometric information through a second sensor module in response to the gesture, determining whether a user's skin contacts the second sensor module based on the first biometric information, and acquiring second biometric information from the user's skin through the second sensor module according to a result of the determination.
