HMD Connection Device Dynamic Display Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices lack a method to set the on/off state of their functions, particularly for turning the display device on or off, which is not addressed in existing technologies.
Innovation Solution
A connection device and display device configuration that includes a control unit to manage display functions, such as displaying images from an information processing device and stopping the display, with storage for display conditions, allowing activation in specific modes based on stored settings when power is applied, including modes where the display can be enabled or disabled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device allows operation to turn on/off the display function, then user control capability is improved, but accidental shutdown or display interruption occurs reducing reliability
Solution Approach 1:
The patent applies dynamics by making the operational response of the display device context-dependent. The control unit dynamically adjusts its behavior based on the current display mode: in the first display mode, operation commands are ignored to prevent accidental shutdown; in the second display mode, operation commands are responded to normally. This dynamic adaptation resolves the contradiction between user control capability and continuous display operation reliability.
2Reliability
If the display device activates in a mode where display stop function is disabled, then accidental shutdown is prevented improving reliability, but user flexibility to manage display modes is reduced
Solution Approach 1:
The patent applies universality by designing the display device to support multiple display modes with different operational characteristics. The device can operate in a first display mode where the display stop function is disabled (preventing accidental shutdown) and a second display mode where the display stop function responds to operations (providing user flexibility). This multi-functionality allows the device to adapt to different user needs and contexts, resolving the contradiction between reliability and adaptability.
3Ease of operation
If the control unit responds to operating unit commands to stop display, then user control over display is improved, but continuous image viewing is interrupted reducing usability
Solution Approach 1:
The patent applies dynamics by making the control unit's response to operating unit commands dependent on the current display mode. In the first display mode, the control unit is configured not to execute the display stop function regardless of operating unit operations, ensuring continuous image viewing. In the second display mode, the control unit executes the display stop function in response to operating unit commands, providing user control. This dynamic behavior resolves the contradiction between display control responsiveness and continuous image viewing.
