Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality devices face limitations in field of view (FoV) due to fixed camera placements, leading to reduced user experience and increased power consumption, while adding more cameras complicates algorithms and space/weight issues.
Innovation Solution
A wearable electronic device with a transceiver, multiple cameras, and a processor that adjusts camera movements to prioritize operations, changing combined FoV and overlapping areas based on context, allowing independent camera movement.

Engineering Contradiction Analysis
1Area of stationary object
If more cameras are added to extend field of view, then user experience is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making cameras movable rather than fixed. The system dynamically adjusts camera positions and orientations based on operation contexts (e.g., hand tracking, SLAM, 3D spatial modeling). This allows the device to extend field of view when needed while reducing power consumption by positioning cameras to capture required data with fewer active sensors.
Solution Approach 2:
The system changes operational parameters of cameras including position, orientation, and field of view settings based on different operation contexts. By adjusting these parameters dynamically, the device can achieve extended field of view coverage without continuously operating all cameras at maximum capacity, thereby reducing overall power consumption.
2Area of stationary object
If more cameras are added to extend field of view, then user experience is improved, but device complexity increases
Solution Approach 1:
The system dynamically configures which cameras are active and how they are positioned based on the current operation context. This dynamic approach allows the use of fewer cameras for specific tasks rather than requiring all cameras to be continuously active, thereby reducing algorithmic complexity while maintaining extended field of view capabilities when needed.
Solution Approach 2:
The patent segments the field of view coverage task across multiple cameras that can be independently positioned and controlled. Each camera handles specific spatial regions or operational requirements, allowing the system to achieve comprehensive coverage without requiring all cameras to process data simultaneously, thus reducing overall algorithmic complexity.
3Area of stationary object
If more cameras are added to extend field of view, then user experience is improved, but placement space and weight increase
Solution Approach 1:
The system uses movable camera modules that can be repositioned within the device structure. This dynamic positioning capability allows the device to achieve extended field of view without adding permanent weight for additional fixed cameras. The same physical cameras can serve multiple spatial positions through movement, reducing the total weight required.
Solution Approach 2:
The patent implements multi-functional camera modules that can serve multiple purposes and positions within the device. Each camera can be repositioned to fulfill different field of view requirements for various operations (hand tracking, SLAM, 3D modeling), eliminating the need for dedicated cameras for each function and thereby reducing overall device weight.
