Display System Aligning Operator Viewpoint for Accurate Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display systems where the position and direction of a display device relative to a user are not fixed, there is a high likelihood that the user may misunderstand the direction of the images and information displayed, leading to misinterpretation of guidance or instructions.
Innovation Solution
A system comprising a first and second display device, where the first display device receives guide information from the second, including operation detection data and line-of-sight direction, to accurately display images corresponding to the operation and viewpoint of the second device's operator, ensuring proper guidance and information alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is used without fixed position and direction relative to the user, then the display device has high flexibility and adaptability, but the user may misunderstand the direction of the displayed image and information
Solution Approach 1:
The system incorporates operation detection units in both the first and second display devices to continuously detect user operations and display device orientations. This feedback mechanism allows the control units to real-time adjust and transmit accurate directional information, ensuring that the displayed images and information maintain correct orientation regardless of device placement flexibility.
Solution Approach 2:
The patent replaces mechanical orientation constraints with electronic detection and communication systems. Instead of physically fixing the display device, the system uses operation detection units, communication units, and control units to electronically track and transmit directional information, achieving the same orientation accuracy without mechanical constraints.
2Adaptability or versatility
If the relative positions of the display device and user are not fixed, then the display system is more versatile, but the direction of displayed information cannot be accurately transmitted
Solution Approach 1:
The operation detection units continuously monitor user interactions and device orientation, providing real-time feedback to the control units. This feedback loop ensures that directional information is accurately detected and transmitted, maintaining measurement precision while preserving system versatility.
Solution Approach 2:
The communication units and control units are designed to handle multiple functions including position tracking, orientation detection, and directional information transmission. This multi-functionality allows the system to maintain accurate directional communication across various display configurations, supporting both versatility and precision simultaneously.

AI summary
In a display system, a projector detects an operation, generates guide information indicating the detected operation, and transmits the guide information to an HMD, and the HMD receives the guide information transmitted from the projector and displays an image corresponding to the operation of the projector and an image indicating a point of view or line-of-sight direction of an operator carrying out the operation, on the basis of the guide information.
