Head-Mounted Display Controller Input Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display systems require users to look at an information processing terminal for input operations, limiting efficiency and convenience.
Innovation Solution
A head-mounted display system with a controller that includes a first display unit for visual recognition of outside scenes and a second display unit for input, allowing input modes to be set based on the display mode of the first unit, enabling intuitive and efficient input operations without needing to look away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users perform input operations on an information processing terminal, then input functionality is achieved, but users must look away from the outside scene displayed on the head-mounted display
Solution Approach 1:
The patent merges the input unit and second display unit into the controller, integrating input functionality with the head-mounted display system. This allows users to perform input operations while maintaining visibility of the outside scene through the first display unit, resolving the contradiction between input convenience and scene visibility.
Solution Approach 2:
The controller serves multiple functions by incorporating both the second display unit for showing input interfaces and the input unit for receiving inputs. This multi-functional design enables users to access input capabilities without sacrificing the primary function of viewing the outside scene, thus addressing the technical contradiction.
2Adaptability or versatility
If the head-mounted display shows a portion of the information processing device image, then coordination between devices is achieved, but input operations still require looking at the information processing terminal
Solution Approach 1:
By merging the input unit and second display unit into the controller, the patent creates an integrated system where input operations can be performed directly through the head-mounted display interface. This eliminates the need to switch attention to a separate information processing terminal, thereby improving ease of operation while preserving device coordination capabilities.
3Adaptability or versatility
If the first display unit displays in multiple modes based on head state, then display adaptability is improved, but system complexity increases
Solution Approach 1:
The display control unit dynamically adjusts the display mode of the first display unit based on the detected head state. This dynamic adaptation allows the system to automatically switch between different display modes (e.g., normal mode, input mode) according to user needs, achieving high adaptability without requiring complex manual configuration.
Solution Approach 2:
The system uses feedback from head state detection to automatically adjust display modes. The detection unit monitors head movements and states, and the display control unit responds by switching to appropriate display modes, creating a closed-loop control system that achieves adaptability through simple feedback mechanisms rather than complex control logic.

AI summary
A method for controlling a display system including a head-mounted display device and a controller coupled to the display device is provided. A first display unit provided in the display device constituting the display system enables an outside scene to be visually recognized. The first display unit is caused to perform display in any mode of a plurality of modes in accordance with a state of the head of a user wearing the display device. At this time, one input mode of a plurality of input modes is set in accordance with a display mode of the first display unit, and input corresponding to each of the plurality of input modes is enabled in coordination with display on a second display unit provided in the controller, and input is received in the input mode.
