3D Image Navigation via Device Orientation and Center of Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems for navigating through three-dimensional image data do not allow users to obtain desired views in a sufficiently convenient manner.
Innovation Solution
An image processing system that includes an image device with a display and an orientation sensor, which measures the device's orientation and provides rotation data to an image processor. The processor establishes a center of rotation within the image data, allowing users to navigate by generating current views based on device rotation relative to a reference view, enabling convenient selection of image data views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users navigate through three-dimensional image data using conventional methods (mouse, keyboard, touch screen), then navigation functionality is provided, but user convenience and ease of operation are insufficient
Solution Approach 1:
The system automatically captures the device's orientation data from the orientation sensor and uses it to determine the current view of the three-dimensional image data without requiring manual input from the user. The device serves itself by converting its physical orientation directly into navigation commands, eliminating the need for complex manual navigation interfaces.
Solution Approach 2:
The patent replaces manual mechanical navigation methods (mouse movements, keyboard inputs, touch screen gestures) with an automated sensor-based system. The orientation sensor detects the device's physical orientation in space and automatically translates it into view navigation, substituting mechanical user interactions with automatic sensor-driven navigation.
2Measurement precision
If the system establishes views based on device rotation without a defined center of rotation, then navigation is possible, but the navigation accuracy and precision are insufficient
Solution Approach 1:
The system performs preliminary action by establishing a center of rotation within the three-dimensional image data before processing orientation data. This pre-established reference point enables accurate calculation of view rotations based on device orientation, improving navigation precision without requiring complex real-time computations.
Solution Approach 2:
The center of rotation acts as an intermediary element between the device's physical orientation and the virtual view navigation. It serves as a fixed reference point that mediates the transformation from physical device rotation to virtual image data rotation, enabling precise and consistent navigation throughout the three-dimensional space.
