HMD Touch Pad Input for Immersive Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display systems lack user-friendly input techniques, making it difficult for a wider demographic to enjoy games, as users struggle with navigating inputs while wearing the device, which can lead to immersion issues and operational challenges.
Innovation Solution
A head-mounted display system with an input device on the outer surface that detects user contact or proximity, allowing intuitive touch input and eliminating the need for external input devices, enabling users to interact with games through touch pads or a mobile information terminal connected to the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a head-mounted display is used to enhance immersion, then the sense of immersion is improved, but the ease of operation deteriorates due to lack of external input devices
Solution Approach 1:
The patent merges the input device with the head-mounted display structure by providing touch-sensitive panels on the outer surface of the HMD. This integration allows users to interact with the display through direct touch while maintaining immersion, eliminating the need for separate external controllers and resolving the contradiction between immersion and ease of operation.
2Ease of operation
If an input device is integrated on the head-mounted display, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The touch-sensitive panel serves multiple functions: it acts as both the display interface and the input device. Users can touch the display screen to input commands, making the system more versatile and reducing the need for separate input hardware, thereby managing device complexity while improving ease of operation.
3Ease of operation
If touch input is enabled on the display surface, then the ease of operation is improved, but the area available for display content decreases
Solution Approach 1:
The touch-sensitive functionality is implemented in specific regions of the display surface rather than the entire area. This allows touch input capability in certain zones while preserving full display content area in other zones, resolving the contradiction between operational ease and display area availability.

AI summary
A head-mounted display 100 wearable on the head of a user includes: a display device disposed on an inner surface of the head-mounted display 100 worn by the user on the head; a touch pad 140 disposed on an outer surface of the head-mounted display 100 worn by the user on the head, the touch pad 140 being able to detect contact with or proximity of a body part of the user; and a display controlling unit acquiring data of an image generated on the basis of input information indicative of the touch pad 140 detecting the contact with or the proximity of the body part of the user, the display controlling unit further causing a display device to display the acquired image data.
