Head-Mounted Display Multisensory Feedback Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted devices (HMDs) for augmented and virtual reality cause eye fatigue and strain due to the constant fusional effort required for binocular systems, especially for users with weak binocular vision or preexisting visual disorders, and struggle with accurate superposition of digital content onto a 3D real-world environment.
Innovation Solution
The HMD system incorporates sensors, illumination devices, and operational components to provide multisensory stimuli, monitor environmental conditions, and adjust for user comfort, including temperature, humidity, and air quality, while enabling real-time diagnostics and treatments, and features such as progressive optical lenses and a visual balancing software module to reduce eye strain and improve content superposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional binocular HMD systems are used to provide immersive augmented or virtual reality content, then the user experience is enhanced, but eye fatigue and strain increase due to constant fusional effort
Solution Approach 1:
The patent divides the visual field into discrete depth layers (first depth plane, second depth plane, etc.) and presents content at different depths to each eye independently. This segmentation of depth perception allows the system to provide immersive 3D content without requiring constant binocular fusion, thereby reducing eye fatigue while maintaining immersive experience.
Solution Approach 2:
The patent introduces depth as an additional dimension beyond traditional 2D display, creating a multi-planar visual experience. By presenting content at multiple depth planes simultaneously to each eye, the system enhances immersion through true 3D perception without relying on stereoscopic fusion that causes strain.
2Adaptability or versatility
If binocular HMD systems are used for augmented reality, then digital content can be overlaid on the real world, but accurate superposition of digital content onto the 3D real-world environment is difficult
Solution Approach 1:
The patent incorporates sensors to detect the user's head position, eye position, and environmental features in real-time. This feedback is used to dynamically adjust the presentation of digital content across multiple depth planes, ensuring accurate superposition of augmented reality content onto the real-world environment while accounting for user movement and perspective.
Solution Approach 2:
The system dynamically adjusts the depth plane configurations and content positioning based on real-time sensor data. The multi-planar display adapts to changing viewing conditions, head movements, and environmental factors, maintaining accurate superposition of digital content with the real world through continuous dynamic recalibration.

AI summary
This application is related to a head-mounted display system and related methods for entertainment, diagnostics, and treatment. The HMD includes various sensors and tools to take physical measurements, perform physical procedures, adjust physical conditions, or manipulate digital data. In some embodiments, the HMD produces different types of sensory stimuli, such as releasing or filtering certain compounds in liquid or aqueous forms in the space near the HMD, or adjusting different physical features of the space near the HMD, such as temperature and flow, to enhance the augmented or virtual reality environment being displayed. In some embodiments, the HMD performs regular monitoring, a specific examination, a surgical intervention, or other care procedures on the eyes automatically or in conjunction with a device of an eye care professional across a computer network to care for the user's eyes in real time or on an ongoing basis.
