HMD Display Adjusting to PC Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems lack the ability to control the display state based on the positional relationship between an external device and a display device, specifically failing to adjust the display according to the external device's position and visibility within the display's field of view.
Innovation Solution
A display system comprising an electronic device with a first display unit and a display device featuring a second display unit that can visually recognize external scenery, where the second display unit adjusts its display based on data input from the electronic device, detecting the position of the first display unit and adjusting its display position, size, and shape to match the positional relationship, and can switch between different display states depending on the visibility of the first display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second display unit displays an image in an overlapping manner with external scenery, then the user can see both the display image and external environment, but the visibility of the display image decreases when the external device is within the visual field
Solution Approach 1:
The patent applies dynamics by making the display parameters (position, size, shape) of the second display unit changeable based on the detected position of the external device. When the external device is within the visual field, the display image parameters are dynamically adjusted to improve visibility, resolving the contradiction between maintaining external scenery visibility and ensuring display image visibility.
2Adaptability or versatility
If the display position and size of the second display unit are fixed, then the device structure is simple, but the display cannot adapt to different positions of external devices
Solution Approach 1:
The patent implements feedback by detecting the position of the external device relative to the visual field of the second display unit and using this information to adjust the display parameters. This feedback mechanism enables the display to adapt to different external device positions while maintaining a relatively simple control system.
Solution Approach 2:
The patent applies parameter changes by modifying the display parameters (position, size, shape) of the second display unit based on the detected position of the external device. This allows the display to adapt to different scenarios without requiring complex structural changes.
3Ease of operation
If the convergence angle is adjusted to match the position of the external device, then the user can focus on both displays, but the control complexity increases
Solution Approach 1:
The patent uses feedback by detecting the position of the external device and adjusting the convergence angle of the second display unit accordingly. This feedback-based adjustment allows the user to focus comfortably on both displays without manual intervention, while the control complexity is managed through automated detection and adjustment mechanisms.

AI summary
Provided is a display system including a PC and an HMD. The HMD includes an image display unit configured so that an external scenery is visually recognizable, the image display unit being configured to display an image in an overlapping manner with the external scenery and a display control unit configured to cause the image display unit to display an image based on data input from the PC. The display system detects a position of the display unit of the PC with respect to the HMD and adjusts the display in the image display unit when the position of the display unit with respect to the HMD is included in a range of the external scenery visually recognized by the image display unit.
