Head-Mounted Display Overlay Placement Outside Terminal Imagery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HMDs require a separate video additional information display control device to prevent additional information from overlapping with the main image, which complicates the system and user experience.
Innovation Solution
The HMD includes an image capturing part to acquire the field of view range image, an additional information presence/absence analysis part to detect superimposed information, and a display controller to position additional information non-overlapping with the information terminal's visual recognition area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information is superimposed on the main image via transparent display, then information display capability is improved, but main image visibility deteriorates
Solution Approach 1:
The patent divides the display area into multiple regions: a first display region for the main image and a second display region for additional information. This spatial segmentation allows both the main image and additional information to be displayed simultaneously without mutual interference, resolving the contradiction between information display capability and main image visibility.
2Ease of operation
If a separate video additional information display control device is used, then additional information display control is improved, but device complexity increases
Solution Approach 1:
The patent integrates the additional information display control functionality directly into the HMD's display controller. The display controller receives the main image signal and additional information signal, then controls their respective display regions independently. This merging of functions eliminates the need for a separate control device while maintaining effective display control.
3Loss of information
If additional information is displayed on the HMD, then information accessibility is improved, but user attention distraction increases
Solution Approach 1:
The patent applies different display characteristics to different regions: the first display region displays the main image with normal transparency, while the second display region displays additional information with adjusted transparency and positioning. This local differentiation ensures that additional information is accessible without excessively distracting the user from the main image.

AI summary
A head mounted display includes a transmissive display, an image capturing part acquires field of view range image, and an additional information presence/absence analysis part that analyzes the acquired field of view range image, confirms whether there is an information terminal included in the field of view range of user and whether a display image of an information terminal included in the field of view range of the user is one in which additional information is superimposed on the main image. An additional information acquisition part requests the information terminal to send additional information, and receives the additional information. A display controller detects an information terminal visual recognition area that is an area where the information terminal is viewed in the transmissive display, and displays the received additional information in a position that does not overlap with the information terminal visual recognition area of the transmissive display.
