Head-Mounted Display Dominant Eye Detection Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with head-mounted displays for virtual and augmented reality experience high power consumption and heat generation due to simultaneous output on both eyes, reducing usage time and increasing temperature.
Innovation Solution
An electronic device that identifies the dominant and non-dominant eye of the user and adjusts the display settings for the non-dominant eye to reduce power consumption, including lowering resolution, frame rate, or display area, using cameras to track eye movements and ambient conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device outputs screens through both the first panel and second panel simultaneously, then the stereoscopic effect is provided, but power consumption increases and usage time is reduced
Solution Approach 1:
The patent applies partial action by disabling the display panel corresponding to the non-dominant eye while maintaining full functionality on the dominant eye side. This allows the device to provide stereoscopic effect through the dominant eye without the excessive power consumption of driving both panels at full performance, directly resolving the contradiction between reliability and energy use.
Solution Approach 2:
The patent implements local quality by applying different display settings to different eyes based on dominance detection. The dominant eye receives full-quality display output while the non-dominant eye has reduced or disabled output, creating localized quality differentiation that reduces overall power consumption while preserving the essential stereoscopic experience through the dominant channel.
2Reliability
If the electronic device outputs screens through both the first panel and second panel simultaneously, then the stereoscopic effect is provided, but temperature increases due to generated heat
Solution Approach 1:
By disabling the display panel for the non-dominant eye, the patent reduces the total computational load and heat generation from the display subsystem. This partial action approach maintains the stereoscopic effect through the dominant eye while preventing excessive temperature rise that would occur if both panels operated at full capacity simultaneously.
3Use of energy by moving object
If the display settings are changed to reduce power consumption, then usage time is extended, but display quality may be affected
Solution Approach 1:
The patent applies local quality differentiation by maintaining high display quality settings for the dominant eye while reducing or disabling display output for the non-dominant eye. This localized approach extends usage time through reduced power consumption while preserving perceived display quality, as the dominant eye receives the full-quality output necessary for optimal visual experience.

AI summary
An electronic device and method are disclosed. The electronic device includes a first camera configured to capture a frontal external environment of the electronic device, a second camera oriented opposite to the first camera and configured to capture gaze directions of a user's left eye and right eye, a first display panel corresponding to the left eye, a second display panel corresponding to the right eye, a memory, and a processor that implements the method, including: identifying, using the second camera, a dominant eye and a non-dominant eye among the left eye and right eye, identifying a dominant display panel from among the first and second display panels corresponding to the dominant eye, and a non-dominant display panel from among the first and second display panels corresponding to the non-dominant eye, and changing settings of the dominant display panel to be different from settings of the non-dominant display panel.
