HMD Focus Space Segmentation for Visual Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted display (HMD) devices face difficulty concentrating on content within a congested environment due to the display of both internal and external objects simultaneously, making it hard to focus on a specific object.
Innovation Solution
An HMD device with a transparent member, display, and sensors that obtain environmental information to set a focus space, allowing users to see objects inside the focus space clearly while blurring or obscuring objects outside, using a processor to manage the display of virtual images on the transparent member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the HMD device displays all objects in the surrounding environment through the transparent member, then the user can see the actual environment clearly, but the user cannot concentrate on a specific object due to visual distractions from other objects
Solution Approach 1:
The patent segments the visual field into a focus space (where the user wants to concentrate) and a non-focus space (surrounding environment). Objects within the focus space are displayed clearly, while objects outside are blurred or obscured. This spatial segmentation allows users to concentrate on specific objects without being distracted by the surrounding environment, resolving the contradiction between seeing the actual environment and concentrating on a specific object.
2Ease of operation
If the HMD device obscures objects outside the focus space to help concentration, then the user can focus better on internal objects, but the user loses awareness of the external environment
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics within different spatial zones. Objects inside the focus space are rendered with high clarity and detail to aid concentration, while objects outside the focus space are rendered with reduced clarity or obscured. This localized differentiation of visual quality allows selective attention without complete environmental isolation, balancing focus and awareness.

AI summary
A head-mounted display (HMD) device is provided. The HMD device includes a transparent member, a display, at least one sensor, and at least one processor functionally connected to the display and the at least one sensor. The at least one processor is configured to obtain information on a surrounding environment of the HMD device via the at least one sensor, set a focus space generated based on a designated location, determine at least one first object positioned inside the focus space and at least one second object positioned outside the focus space, based on the information on the surrounding environment and the focus space, and display, via the display, a virtual image in an area of the transparent member, wherein the at least one second object is seen in the area.
