Dual Screen Head Mounted Display External Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted displays (HMDs) impede interaction with individuals other than the user by not allowing for effective communication or information exchange, as they primarily focus on the user's experience without consideration for external interaction.
Innovation Solution
Incorporating an external display and controller system within the HMD that allows for the display of user information and host system information to others, enabling communication and interaction through internal and external displays, sensors, and touch-sensitive devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an HMD displays only internal information for the user, then the user's visual experience is optimized, but interaction with external persons is impeded
Solution Approach 1:
The HMD display system is segmented into two distinct displays: an internal display for the user and an external display for external persons. This segmentation allows each display to serve its specific function independently, resolving the contradiction between optimizing user experience and enabling external interaction.
Solution Approach 2:
The external display acts as an intermediary between the user inside the HMD and external persons. It mediates communication by displaying external information (such as contact information, availability status, or messages) that enables interaction without requiring the user to remove or adjust the HMD.
2Manufacturing precision
If the HMD focuses solely on user experience, then display quality for the user is improved, but communication capability with others deteriorates
Solution Approach 1:
The HMD system is designed with multi-functionality by incorporating both an internal display for user-centric functions and an external display for communication functions. This universal design allows the single device to serve multiple purposes: maintaining high display quality for the user while simultaneously providing communication capabilities with external persons.
3Device complexity
If no external display is provided, then the HMD structure remains simple, but information exchange with external persons is limited
Solution Approach 1:
The solution adds a new dimension to the HMD by incorporating an external display that faces outward toward external persons, rather than only inward toward the user. This dimensional addition enables information exchange in a previously unavailable direction, allowing the HMD to display information to external persons without significantly complicating the overall device structure.
Data Source
AI summary
An apparatus and method are presented for displaying information on a head mounted display (HMD). The HMD includes an internal display, visible to a user of the HMD, and an external display, visible to a person other than the user. The method includes displaying internal information on the internal display and displaying external information on the external display, where the external information relates to host system information received from the host system or user information relating to the user.
