Eye-Tracking Display Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic displays in devices like near-eye display systems consume excessive power, particularly in battery-powered devices where power is limited, leading to inefficient energy management.
Innovation Solution
Implementing an image segmentation system that uses eye-tracking technology to determine the user's gaze direction, allowing the display to adjust its power consumption based on whether the user is looking at the display or not, thereby optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is kept on continuously to ensure availability, then user convenience is improved, but power consumption increases
Solution Approach 1:
The display system dynamically adjusts its operational state between active and inactive based on real-time eye-tracking detection. The display transitions from a continuously on state to a conditional state where it activates only when the user's gaze is detected, thereby reducing unnecessary power consumption while maintaining availability when needed.
Solution Approach 2:
The system uses eye-tracking technology to provide feedback about user attention state to the display control mechanism. This feedback loop enables the display to respond adaptively to user presence, activating when the user looks at it and remaining inactive otherwise, thus resolving the contradiction between availability and power consumption.
2Adaptability or versatility
If eye-tracking technology is implemented to detect user gaze, then power management capability is improved, but device complexity increases
Solution Approach 1:
The eye-tracking system serves multiple functions: it detects user gaze for power management purposes, potentially tracks user attention patterns, and provides input for display activation decisions. By making this single component multi-functional, the patent reduces the need for additional separate systems, thereby limiting the increase in overall device complexity while achieving improved power management adaptability.
Data Source
AI summary
A display system is disclosed. The display system includes a display, an eye-tracking sensor, and a processor communicatively coupled to the display and the eye-tracking sensor. The computing device receives data from the eye-tracking sensor, determines, based on the eye-tracking data, whether a user's eye is looking at a display in the display system, and based on whether the eye is determined to be looking at the display, controls a power consumption of the display.
