HMD Overlaying Work Lists on Real-World Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require operators to move their visual line significantly to view both a work list and a target object, making it cumbersome to display information related to a person's motion targeting a place or object effectively.
Innovation Solution
A display device with a control section that displays information and changes the display based on user input, allowing operators to view targets and motion information without large visual line movements, using a Head-Mounted Display (HMD) that overlays images on the real world, with features like item lists, checkboxes for completion, and color-coded targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information related to motion is displayed on a separate screen, then the information can be clearly shown, but the operator needs to move visual line significantly to view both the target object and the screen
Solution Approach 1:
The patent combines the display of motion information with the view of the target object by superimposing the work list and motion information over the real-world scene through the HMD. This allows the operator to view both the target object and motion information simultaneously without moving the visual line, resolving the contradiction between information display clarity and ease of operation.
Solution Approach 2:
The patent transitions from a two-dimensional screen display to a three-dimensional augmented reality display where information is overlaid on the real-world scene. This dimensional change allows the operator to view information and target objects in the same spatial plane, eliminating the need for visual line movement between separate screens and the target.
2Loss of information
If a work list is displayed on a screen, then the work procedure information can be provided, but the operator cannot view the target object and the work list simultaneously
Solution Approach 1:
The patent merges the work list display with the target object view by superimposing the work list over the real-world scene. This allows the operator to view both the target object and work procedure information simultaneously without time loss for visual line movement, resolving the contradiction between information provision and time efficiency.
3Loss of information
If the display shows detailed motion information, then the operator can understand the work procedure, but the display becomes complex and distracting from the target object
Solution Approach 1:
The patent applies local quality by displaying different types of information in different visual regions or with different visual weights. The target object remains the primary focus while motion information is displayed in a complementary manner, ensuring information completeness without creating overall display complexity that would distract from the target.

AI summary
An HMD includes an image display section configured to display an image to be visually recognizable through an outside scene. The HMD includes a position detecting section configured to recognize an input and a control section configured to cause the image display section to display information and change the display in the image display section according to the input recognized by the position detecting section.
