Map Orientation Alignment with Live Camera Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices that provide map information struggle to help users navigate in environments where distinguishing directions is difficult, as they only offer map information or route guidance without visual context.
Innovation Solution
An electronic device and method that simultaneously displays map information and live video, aligning the orientation of the map with the direction information sensed by the device's camera, allowing for intuitive navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If map information is displayed alone, then the device complexity is low, but the ease of operation deteriorates in environments where direction distinction is difficult
Solution Approach 1:
The patent combines map information display with camera-based live video feed into a single integrated navigation interface. The map and camera view are merged such that the map orientation aligns with the camera's real-world viewing direction, allowing users to navigate by looking at the screen rather than interpreting separate map and camera displays.
Solution Approach 2:
The patent transitions from a traditional 2D top-down map view to a 3D perspective that aligns the map with the camera's field of view. This dimensional transformation creates an immersive navigation experience where the map represents the real-world environment as seen through the camera, improving directional understanding.
2Loss of information
If only route information is provided, then the information processing is simple, but the loss of information increases in environments where direction is hard to distinguish
Solution Approach 1:
The patent merges route guidance information with the camera's live view, overlaying navigation instructions on the real-time camera feed. This integration ensures that directional information is not lost but rather enhanced by combining it with the user's current visual perspective.
Solution Approach 2:
The camera acts as an intermediary between the physical environment and the navigation system. By using the camera's view as the reference frame for displaying map information and route guidance, the system preserves and enhances directional information without requiring complex separate processing of map and camera data.
Data Source
AI summary
An electronic device is provided and includes a camera configured to obtain an image, and a location information sensor configured to obtain (or sense) a current location of the electronic device. The electronic device further includes a direction information sensor configured to obtain (or sense) direction information about a direction in which the camera obtains the image and a memory configured to store information about the current location. A processor configured to operatively connect with the location information sensor, the direction information sensor, and the memory, may be further configured to obtain map information corresponding to the current location and arrange and display an orientation of the obtained map information with an orientation corresponding to the direction information. The processor may be configured to output the obtained map information together with a live video obtained by the camera.
