Gyro-Controlled Virtual Camera Auto-Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional video game software environments, players face frustration when objects of interest move out of the virtual camera's field-of-view due to camera movements, requiring constant repositioning of the gaming device to maintain the object in view.
Innovation Solution
A system that uses angular velocity sensors to automatically center the virtual camera on an object of interest, adjusting its position and orientation based on device movements, ensuring the object remains at the center of the field-of-view even as the camera changes position and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion sensing technology is used to move the virtual camera based on device movement, then the player can control the camera position and direction, but the object of interest moves out of the field-of-view requiring constant repositioning
Solution Approach 1:
The system continuously monitors the virtual camera's position and the object of interest's position, calculates the offset between them, and automatically adjusts the camera to maintain the object in the center of the field-of-view. This closed-loop feedback mechanism resolves the contradiction by automatically compensating for camera movements without requiring manual intervention.
Solution Approach 2:
The virtual camera system automatically centers itself on the object of interest without requiring the player to manually reposition the device. The system serves itself by detecting when the object moves out of view and autonomously adjusting the camera position, eliminating the need for constant player intervention.
2Adaptability or versatility
If the virtual camera moves relative to the device movement, then the player can explore the game environment, but the object of interest moves entirely out of the field-of-view
Solution Approach 1:
The system dynamically adjusts the virtual camera's position and orientation based on real-time detection of the object of interest's location. The camera automatically repositions itself to maintain the object in the center of the field-of-view, providing adaptive camera control that responds to changing game conditions without requiring manual player input.
3Adaptability or versatility
If the player moves the device to change viewpoint, then the player can see different parts of the game world, but must constantly reposition the device to keep the object in view
Solution Approach 1:
The system continuously monitors the relationship between the virtual camera position and the object of interest position, calculating the offset and automatically adjusting the camera to maintain the object in the center. This feedback loop eliminates the need for manual device repositioning, resolving the time loss associated with constantly adjusting the device.
Solution Approach 2:
The system proactively adjusts the virtual camera position before the object completely moves out of the field-of-view. By continuously monitoring the object's position and predicting its movement, the camera preemptively repositions itself to maintain optimal viewing, eliminating the need for reactive manual adjustments.

AI summary
An apparatus and method is provided for gyro-controlled gaming viewpoint with auto-centering. A virtual camera is positioned at a first position while the virtual camera views a first object at a first direction. Once the system moves, the virtual camera moves to a second position based on a measurement by an angular velocity sensor. While the virtual camera moves to the second position, the viewing direction of the virtual camera simultaneously so as to keep the first object positioned in a same position of a viewing direction of the virtual camera. The apparatus and method allow the system to move a virtual camera based on a measurement of a gyroscope while keeping an object of importance in the center of the field-of-view of the virtual camera.
