Head-Mounted Display Line-of-Sight Object Information Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality display systems using head mount displays face challenges in maintaining user immersion while providing necessary game information, such as character details, which can diminish the sense of immersion if not displayed effectively.
Innovation Solution
A display system with a virtual camera specifier that aligns a virtual camera's visual axis and position based on the user's head-mounted display device's direction and position, allowing information associated with objects in the virtual space to be displayed only when the user's line of sight intersects with those objects, thereby enhancing immersion without cluttering the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If game information is displayed on the virtual space image in the head mount display, then the user can access game details conveniently, but the sense of immersion in the game is diminished
Solution Approach 1:
The patent applies local quality by displaying game information only in the specific local area where the user's line of sight intersects with game characters or objects, rather than displaying information globally across the entire field of view. This localized display approach provides game information exactly where the user is looking, maintaining immersion in the virtual environment while still delivering necessary information when needed.
Solution Approach 2:
The patent implements dynamics by making the display of game information dynamic and conditional based on the user's line of sight direction and position. The information display automatically adjusts - appearing when the line of sight intersects with targets and disappearing when it doesn't - creating a dynamic interaction between the user's viewing behavior and the information presentation, rather than using static continuous display.
2Reliability
If game information is not displayed, then the sense of immersion is maintained, but the user feels inconvenient
Solution Approach 1:
The patent applies preliminary action by pre-positioning information display capabilities in the virtual space that are ready to activate when conditions are met. The system continuously monitors line of sight intersection with game objects and automatically presents information in advance of the user's need, without requiring explicit requests or menu navigation, thus maintaining immersion while ensuring information availability.
Solution Approach 2:
The patent implements feedback by creating a closed-loop system where the display of game information responds to the user's line of sight behavior. The system detects when the line of sight intersects with game characters or objects and provides relevant information as feedback, then stops displaying when the intersection ends, creating an adaptive information presentation that responds to user interaction patterns.
3Loss of information
If information is displayed continuously, then the user has constant access to game details, but the virtual reality experience is cluttered and distracting
Solution Approach 1:
The patent applies the taking out principle by extracting the information display function from continuous presence and making it conditional and selective. Instead of having information constantly visible throughout the virtual environment, the system extracts and presents information only in the specific spatial and temporal context where it is relevant - when the line of sight intersects with the corresponding game objects - thereby reducing visual clutter while maintaining information availability.

AI summary
A display system including a display device which is used by being mounted on the head of a player, comprising: a virtual camera specifier that specifies a visual axis and/or a position of a virtual camera in a virtual space, according to a direction and/or a position of the display device; and a displayer that displays an object present in the virtual space, on the display device, according to the visual axis and/or the position of the virtual camera, wherein in a case where there is an object on the visual axis specified by the virtual camera specifier, the displayer additionally displays information associated with the object.
