Wearable Camera Image Switching via Positional Icon Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring with wearable cameras lack an intuitive method for selecting and switching between cameras, increasing operator burden due to the need to consider camera positions and orientations, and do not efficiently manage image selection from multiple cameras.
Innovation Solution
A display image switching apparatus and method that includes an image selection section, object selection section, camera extraction section, and camera position calculation section to display camera position information, allowing operators to intuitively select and switch between camera images by identifying the position of wearable cameras on a monitoring screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators select cameras by considering position and orientation on a planar map, then camera selection capability is achieved, but operator burden increases
Solution Approach 1:
The patent introduces an intermediary element (camera icon displayed on the monitoring screen) that mediates between the operator and the actual camera selection. Instead of directly selecting cameras through complex position and orientation parameters on a planar map, the operator interacts with simplified visual icons that represent cameras, making the selection process more intuitive and easier to operate
Solution Approach 2:
The patent creates a visual copy or representation of cameras in the form of icons displayed on the monitoring screen. These icons replicate the essential information needed for camera selection without requiring operators to interpret complex spatial data, thereby simplifying the interaction while maintaining accurate camera identification
2Measurement precision
If operators frequently move line of sight between planar map and picked-up images, then camera selection accuracy is improved, but operator burden increases
Solution Approach 1:
The patent merges the camera selection interface with the monitoring screen by displaying camera icons directly on the same screen where picked-up images are shown. This integration eliminates the need for operators to switch between separate planar map and image display, allowing them to maintain a consistent visual context while accurately selecting cameras
Solution Approach 2:
The patent transitions from a two-dimensional planar map navigation to a superimposed display where camera icons are positioned directly on the monitoring screen in the same spatial context as the picked-up images. This dimensional integration allows operators to select cameras based on visual position correspondence without moving their line of sight between separate displays
3Adaptability or versatility
If wearable cameras are used instead of stationary cameras, then monitoring flexibility is improved, but camera selection complexity increases
Solution Approach 1:
The patent enables wearable cameras to automatically provide their position and orientation information, which is then used to generate and display appropriate camera icons on the monitoring screen. The system self-manages the complexity of tracking multiple moving cameras, allowing operators to simply interact with the displayed icons without dealing with the underlying complexity of camera positioning and orientation data

AI summary
A display image switching device lightens the burden imposed upon an operator, when selecting a particular camera from a plurality of cameras accompanying movement, by providing an intuitive and easy to understand selecting method. When an operator selects an object from an image picked-up and displayed on a display by a camera selected from a plurality of cameras by a camera, selector, a camera extractor extracts all other cameras picking-up the selected object. A camera icon generator arranges camera icons at positions on the displayed image where the extracted cameras are located. When a camera icon displayed on the display is selected, an image picked-up by the camera at the position of the selected camera icon is displayed on the display.
