Head-Mounted Display Content Positioning for Social Gaze Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-mounted displays, it is difficult for surrounding individuals to determine whether the wearer is viewing content or the real space, leading to an unpleasant feeling when the wearer appears to gaze at them.
Innovation Solution
An information processing device with a display control unit and a decision unit that displays content on a head-mounted display and moves the content image's position based on camera images to avoid aligning with surrounding people, thereby adjusting the wearer's line of sight to reduce perceived gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearer views content on the head-mounted display, then the content display function is improved, but the surrounding person experiences an unpleasant feeling due to perceived gaze
Solution Approach 1:
The display position of the content image is dynamically adjusted based on the detected position of surrounding persons. The system continuously monitors the environment and modifies the content display location in real-time to prevent the wearer's line of sight from aligning with surrounding persons, thereby eliminating the unpleasant feeling while maintaining content viewing functionality.
Solution Approach 2:
The system uses camera images to detect surrounding persons and provides feedback to the display control unit. This feedback loop enables the system to automatically adjust the content image position based on the detected spatial relationship between the wearer and surrounding persons, resolving the contradiction between content display and social comfort.
2Device complexity
If the content image position is fixed, then the display control is simplified, but the wearer may inadvertently gaze at surrounding persons
Solution Approach 1:
The content image position transitions from a fixed state to a dynamic state that automatically adjusts based on detected surrounding persons. This dynamic adjustment prevents the wearer from inadvertently gazing at surrounding persons while the system manages the complexity through automated detection and control algorithms.
3Reliability
If the head-mounted display blocks the field of view, then the content immersion is improved, but the surrounding person cannot determine what the wearer is viewing
Solution Approach 1:
By dynamically adjusting the content image position based on surrounding person detection, the system indirectly communicates the wearer's viewing focus to surrounding persons. The adjustment pattern provides visual cues about what the wearer is attending to, partially recovering the lost information while maintaining immersion.

AI summary
An information processing device (1) according to an embodiment includes a display control unit (34) and a decision unit (31). The display control unit (34) displays a content image on a head-mounted display. During display of the content image by the display control unit (34), the decision unit (31) decides whether or not a surrounding person exists in a front direction of the head-mounted display on the basis of a camera image obtained by capturing an image of a surrounding environment of the head-mounted display. In a case where the decision unit (31) decides that a surrounding person exists, the display control unit (34) moves a display position of the content image.
