HMD Reality Image Recording for Surroundings Safety Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) hinder users from checking their surroundings, making them defenseless in crowded areas, and existing recording techniques do not ensure user safety.
Innovation Solution
An image processing apparatus that captures and saves reality images of the user's surroundings while wearing an HMD, allowing for later review and providing a sense of security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a head-mounted display is worn to view virtual reality videos, then the user can experience immersive virtual content, but the user cannot check their real-world surroundings and becomes vulnerable in crowded areas
Solution Approach 1:
The patent captures reality images using cameras and stores them for later review. This creates a visual copy of the real-world surroundings that the user can examine after removing the HMD, allowing safety verification without compromising the immersive virtual experience during usage
Solution Approach 2:
The system proactively captures and stores reality images before the user potentially encounters danger. By recording the surroundings in advance during HMD usage, the user can later review whether they missed important real-world events or safety concerns
2Reliability
If cameras are installed to record videos for crime prevention, then safety monitoring is improved, but the device complexity and power consumption increase
Solution Approach 1:
The HMD device performs multiple functions: it provides immersive virtual reality display while simultaneously capturing reality images for safety monitoring. The existing camera hardware in the HMD is utilized for dual purposes, avoiding the need for separate dedicated monitoring devices and reducing overall system complexity
Solution Approach 2:
The HMD system automatically captures and stores reality images without requiring external dedicated monitoring equipment. The device serves its own safety monitoring needs using its built-in cameras and processing capabilities, eliminating the need for additional complex external systems

AI summary
An image processing apparatus controls a display device wearable on a head of a user and includes: an obtainment unit configured to obtain a reality image which is an image captured of an actual space around the user and a saving unit configured to save the reality image obtained by the obtainment unit, in a state when the display device is being worn by the user.
