Head-Mounted Display Preview Interface Positioning for Detached Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) lack an effective method to determine the position of an image preview interface when the camera unit is detached, affecting user experience and functionality.
Innovation Solution
A head-mounted display system comprising a first body with a display unit and a second body with a camera unit, where the processor determines the position of the image preview interface based on the position and orientation of the second body relative to the first body, even when detached, to ensure intuitive and accurate image capture and preview.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera unit is made detachable from the head-mounted display, then the adaptability and versatility of the device is improved, but the ability to accurately determine the position of the image preview interface deteriorates
Solution Approach 1:
The system pre-stores multiple candidate positions for the image preview interface corresponding to different camera positions. When the camera is detached, the processor quickly retrieves the appropriate preview position from pre-stored data based on the detected camera position, avoiding complex real-time calculations and ensuring accurate preview positioning despite the detachable configuration
Solution Approach 2:
The system continuously detects the position of the detached camera unit and uses this feedback information to dynamically adjust and determine the correct position of the image preview interface on the display. This closed-loop feedback mechanism ensures that the preview interface accurately reflects the actual camera position regardless of attachment status
2Ease of operation
If the camera unit is detached from the head-mounted display, then the ease of operation is improved, but the reliability of image capture functionality deteriorates
Solution Approach 1:
The system detects whether the camera unit is attached or detached and uses this feedback to automatically adjust the image preview interface position and configuration. This ensures that the image capture functionality remains reliable and intuitive regardless of the camera's attachment status, as the interface adapts to the current operational state
Solution Approach 2:
The image preview interface position is made dynamic rather than fixed. The system can switch between different preview positions depending on whether the camera is attached or detached, allowing the interface to adapt to different operational modes and maintain reliability across various usage scenarios
