Mobile Device Eye Tracking Auto-Start via Scenario Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it inconvenient to operate mobile devices manually in situations where their hands are occupied, such as during a meeting, leading to difficulties in starting the eye tracking function and using related services.
Innovation Solution
A method for a mobile device to automatically start the eye tracking function by determining if it is in a preset scenario, such as a meeting, and enabling the function when the user's eye enters a monitoring area, allowing the device to unlock the screen and trigger applications with gaze actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile device requires manual operation to start the eye tracking function, then the device can ensure secure control, but the ease of operation deteriorates when the user's hands are occupied
Solution Approach 1:
The mobile device automatically detects the preset scenario (meeting mode) and autonomously starts the eye tracking function without requiring manual user input. The device monitors for eye presence in the monitoring area and automatically initiates the eye tracking service, allowing the system to serve itself rather than requiring continuous manual control.
Solution Approach 2:
The system performs preliminary detection of the meeting scenario and prepares the eye tracking function in advance. When the user's eye enters the monitoring area, the device has already been configured to automatically start the eye tracking function, eliminating the need for manual activation at the moment of need.
2Ease of operation
If the mobile device automatically starts the eye tracking function in preset scenarios, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The automatic eye tracking activation is applied locally to specific preset scenarios (such as meeting mode) rather than being a universal feature across all device operations. This localized application reduces overall system complexity by enabling automation only where needed while maintaining manual control elsewhere.
Solution Approach 2:
The system introduces a scenario detection intermediary that mediates between manual operation and automatic eye tracking activation. The intermediary detects preset scenarios and conditions (eye presence in monitoring area) and triggers the appropriate mode, simplifying the control architecture by using a dedicated detection layer rather than complex integrated decision-making.
3Productivity
If the mobile device monitors eye actions continuously, then the productivity improves by enabling hands-free operation, but the energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic detection by checking for eye presence in the monitoring area at specific intervals or triggered events. The eye tracking function is activated periodically when conditions are met (eye detected in monitoring area during preset scenarios) rather than running continuously, reducing energy consumption while maintaining productivity benefits.
Solution Approach 2:
The system performs preliminary scenario detection and eye presence monitoring before activating the full eye tracking function. By detecting preset scenarios and eye position in advance, the system can activate eye tracking only when needed, avoiding continuous operation and associated energy consumption while still enabling hands-free productivity when conditions are appropriate.

AI summary
A method includes determining that a mobile device is in a preset scenario, starting at least one monitor, detecting that an eye of a user has entered a monitoring area of the at least one monitor, enabling an eye tracking mode, collecting a first gaze action of the eye whose duration is not less than a first preset threshold, and starting the eye tracking function.
