Head-Worn Image Display Input with Touch Regions and Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical systems in mixed reality (MR) devices, such as head-worn displays, struggle with effectively integrating user input methods that enhance immersion and interaction with virtual content, particularly in augmented reality (AR) scenarios where real-world and virtual objects are concurrently viewed.
Innovation Solution
A processing unit in the head-worn image display device assigns a specific area of the screen to sense finger-actions, generating electronic signals to change displayed content based on user interactions, including haptic feedback mechanisms to enhance user interaction and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a head-worn image display device uses traditional input methods (buttons, controllers), then device complexity is reduced, but user interaction and immersion in virtual content are insufficient
Solution Approach 1:
The patent combines the display screen with touch-sensitive capabilities, merging the output interface with the input interface. The screen serves dual purposes: displaying visual content and detecting finger actions through integrated sensors, thereby improving user interaction without adding separate input devices
Solution Approach 2:
The display device provides input capabilities through its own screen, eliminating the need for external controllers or buttons. The screen itself becomes the input device by detecting finger actions directly on its surface, allowing the device to serve its own input needs
2Ease of operation
If the entire screen is used for display, then display area is maximized, but finger-action sensing capability is lost
Solution Approach 1:
The patent implements local quality by making only specific regions of the screen touch-sensitive while other regions remain dedicated to display. This allows different areas of the screen to have different functions: some areas for finger-action detection and others for uninterrupted visual content display
Solution Approach 2:
The screen is segmented into multiple functional zones: touch-sensitive regions for detecting finger actions and non-touch regions for pure display. This segmentation allows the system to simultaneously maintain display area and input capability by dividing the screen's functionality across different spatial regions
