HMD Display Mode Switching for Intuitive Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) systems require users to perform operations while viewing a processing device's display, making intuitive operation challenging, especially when using multiple display units.
Innovation Solution
A display system comprising a head-mounted display device with a first display unit and a control device featuring a second display unit and a touch sensor, allowing for multiple display modes, including a common mode and a mode where displays differ, enabling states for operation, application execution, and transition between them, with the first display mode activated during state transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user wears the HMD and performs operations on the processing device display, then the operation can be performed, but the operation becomes less intuitive because the user cannot see the control device display
Solution Approach 1:
The patent copies the display content from the control device (second display unit) to the HMD (first display unit) during state transitions. This allows the user to see the same operational interface on both displays simultaneously, making operations intuitive while wearing the HMD without losing visibility of the control device display
Solution Approach 2:
The system introduces a display mode switching mechanism as an intermediary between the two display units. During specific state transitions, the system activates a common display mode where both displays show the same content, mediating the information flow between the HMD and control device to ensure the user can perform operations intuitively
2Adaptability or versatility
If multiple display units are used to improve usability, then more display information is available, but the system complexity increases
Solution Approach 1:
The patent implements dynamic display modes that automatically switch between common mode and different mode based on the operational state. The system transitions between displaying the same content on both units or different content, reducing the complexity of managing multiple display units while maintaining adaptability for various usage scenarios
Solution Approach 2:
The system provides universal functionality by enabling the same display content to be shown on both the HMD and control device during state transitions. This multi-functional approach allows the display system to serve both as a synchronized information display and as an independent operation interface, reducing the need for complex separate configurations
3Adaptability or versatility
If the display mode switches between common and different modes, then the display flexibility is improved, but the transition control complexity increases
Solution Approach 1:
The patent defines specific operational states (first state, second state, third state) in advance and pre-determines when display mode transitions should occur. By establishing clear state-based transition rules beforehand, the system achieves display flexibility while avoiding complex real-time decision-making logic during operation

AI summary
The display system includes an HMD and a control device. The display system includes a plurality of display modes including a first display mode in which display on an image display unit and display on a touch panel are common and a second display mode in which display on the image display unit and display on the touch panel are different from each other. A first state, a second state, and a third state are capable of being executed, the first state being a state in which at least any one of display on the image display unit and display on the touch panel is stopped, the second state being a state of requesting a specific operation, and the third state being a state in which an application is executable. During specific transition from the first state, the second state, or the third state to another state, the first display mode is set.
