Iris Recognition Motion Trigger and Face Contour Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iris recognition technologies in mobile devices suffer from slow startup speed and poor user experience due to the need for a power button press to initiate the recognition process.
Innovation Solution
An iris recognition method that utilizes a motion sensor to detect device motion, triggering an infrared camera to capture a user's image and perform iris recognition when a face contour is detected, thereby eliminating the need for a power button press and reducing waiting time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the iris recognition module is activated only after pressing the power button, then the device maintains lower power consumption and simpler operation flow, but the startup speed is slow and user experience is poor
Solution Approach 1:
The motion sensor continuously monitors device motion in advance before the iris recognition process is initiated. When the device detects motion patterns indicating the user is bringing the device to their face, it pre-activates the iris recognition module, eliminating the delay caused by requiring a power button press and enabling faster startup.
2Productivity
If the iris recognition process is manually initiated by pressing the power button, then the device maintains simpler control logic, but the unlocking time is prolonged and efficiency is reduced
Solution Approach 1:
The system automatically initiates the iris recognition process by detecting device motion and face proximity without requiring manual user input. The motion sensor and control logic work together to autonomously determine when to activate the infrared camera and iris recognition module, eliminating the need for users to press the power button and significantly reducing unlocking time.
3Speed
If the infrared camera continuously captures images for iris recognition, then the recognition speed is maximized, but the power consumption increases significantly
Solution Approach 1:
Instead of continuous operation, the infrared camera and iris recognition module are activated periodically only when the motion sensor detects specific motion patterns indicating the user is bringing the device to their face. This on-demand activation maintains fast recognition capability while dramatically reducing overall power consumption compared to continuous operation.
