HMD Display Information Processing for Third-Party Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) create a situation where only the user can view the virtual image, leading to unnatural reflections of operations like gestures or sounds when viewed by a third person, as existing technologies do not consider the perspective of the third person.
Innovation Solution
A head-mounted display system that transmits processed display information to an image display apparatus, allowing a third person to perceive the user's actions naturally by reducing the detail and clarity of the information, and adjusting processing methods based on the type of information and user authority, thereby reducing artificiality and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display information is transmitted to an image display apparatus for third-person viewing, then the artificiality of operations is reduced, but information security may be compromised
Solution Approach 1:
The patent applies local quality by differentiating the display information into two versions: one for the user (full detail) and one for third-party viewing (processed with reduced detail). The processing unit selectively modifies specific portions of the display information based on the intended audience, maintaining high quality for the user while providing anonymized versions to third parties, thus resolving the contradiction between naturalness and security.
Solution Approach 2:
The patent creates a copy of the display information that is processed differently from the original. Instead of transmitting the actual display information directly to the image display apparatus, the system generates a processed copy that preserves the operational context for third-person understanding while removing sensitive details, thereby maintaining both naturalness and information security.
2Loss of information
If detailed display information is transmitted to the image display apparatus, then information clarity is improved, but security is reduced
Solution Approach 1:
The processing unit applies local quality by selectively processing different portions of the display information with different levels of detail. Sensitive information is anonymized or obscured while non-sensitive operational context is preserved in full detail, allowing third parties to understand operations without accessing confidential data, thus balancing clarity and security.
Solution Approach 2:
The patent employs parameter changes by modifying the display information through processing operations that alter its characteristics. The processing unit changes parameters such as detail level, resolution, or anonymity degree of the transmitted information, creating a version that maintains sufficient clarity for operational understanding while reducing security risks through controlled parameter modification.
3Reliability
If the processing unit processes display information to reduce detail and clarity, then security is improved, but information utility for third-person understanding may be reduced
Solution Approach 1:
The processing unit applies partial action by selectively processing only the portions of display information that require security protection. Instead of overly processing the entire information set, the system identifies and processes only sensitive elements while leaving non-sensitive operational context unchanged, maintaining sufficient utility for third-person understanding without compromising security-critical data.
Solution Approach 2:
The patent inverts the traditional approach by not filtering out sensitive information but rather selectively preserving it while transforming non-sensitive information into a shareable format. The processing unit works backwards from the security requirement, identifying what must remain protected and allowing everything else to be processed for third-party viewing, thus maintaining both security and utility.

AI summary
A head mounted display which enables a user to visually recognize a virtual image includes: an image display unit that causes the user to visually recognize the virtual image; a processing unit that processes display information, which is information displayed to the user as the virtual image, in the image display unit; and a transmission unit that transmits the processed display information to an image display apparatus which is connected to the head mounted display.
