Wearable Video Device Dual Camera Angular Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable video devices with cameras protruded to provide a "see-what-I-see" view face challenges in size and stability when worn on the ear, as the camera position is easily altered by user movement, making it difficult to maintain the view.
Innovation Solution
A wearable video device with a first and second camera module, each rotated outward at a predetermined angle from the central axis, and a main circuit to process their images, allowing partial overlap of views to enhance stability and image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is protruded to a position near the user's eyes to provide a see-what-I-see view, then the camera can capture the user's field of view, but the camera size becomes large and difficult to fix stably on the ear
Solution Approach 1:
The patent divides the imaging function into multiple camera modules (first camera module and second camera module) positioned at different locations on the wearable device. Each camera module captures a portion of the field of view, and their combined views provide the complete see-what-I-see experience without requiring a single large protruding camera
Solution Approach 2:
Instead of positioning a single camera along the central axis (one-dimensional approach), the patent distributes camera modules across multiple spatial dimensions - placing them at different angular positions relative to the central axis. This multi-dimensional arrangement allows compact positioning while maintaining comprehensive field of view coverage
2Ease of operation
If the camera is positioned to capture the see-what-I-see view, then the user can see through the camera, but the camera position is easily altered by user movement
Solution Approach 1:
The patent combines multiple camera modules into a single integrated wearable device structure that is worn together on the user's head. The hanger and housing structure merges the support function for multiple cameras while maintaining ease of wearing as a single unit, preventing individual camera displacement through unified structural support
3Device complexity
If a single camera is used to provide the see-what-I-see view, then the device structure is simple, but the camera must be large and protruding to capture sufficient field of view
Solution Approach 1:
The imaging system is segmented into multiple smaller camera modules instead of one large camera. Each module has a smaller individual field of view, but collectively they cover the complete user field of view. This segmentation allows compact camera positioning without requiring large protruding structures
Solution Approach 2:
The patent transitions from a single-camera central-axis arrangement to a multi-camera distributed angular arrangement. By utilizing angular distribution in addition to radial positioning, the system achieves comprehensive coverage with smaller cameras positioned closer to the user's ear

AI summary
A wearable video device is provided. The video device wearable includes a first hanger and a second hanger by which the wearable video device is connected to a user, a first camera module that is installed in the first hanger, the first camera module having a first optical axis that is rotated outward at a predetermined first angle from a central axis of the wearable video device, and the first camera module being configured to generate a first image, a second camera module that is installed in the second hanger, the second camera module having a second optical axis that is rotated outward at a predetermined second angle from the central axis of the wearable video device, and the second camera module being configured to generate a second image, and a main circuit that controls the first camera module and the second camera module, and that processes at least a portion of the first and second images, wherein a first view of the first camera module and a second view of the second camera module partially overlap.
