Goggle-Based Virtual Camera Control to Keep Objects in View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems require manual operation to direct the line of sight of a virtual camera to an object, leading to suboptimal operability in virtual spaces.
Innovation Solution
An image display system that includes a goggle apparatus with object placement, orientation acquisition, camera rotation, and detection means to automatically adjust the virtual camera or object position based on changes in the user's line of sight, ensuring the object remains within the camera's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to direct the line of sight of the virtual camera to the object, then the system structure remains simple, but the ease of operation deteriorates
Solution Approach 1:
The system automatically tracks and follows the user's head orientation to adjust the virtual camera's line of sight, eliminating the need for manual camera direction operations. The detection means detects head orientation changes and the control means automatically adjusts the camera angle, making the system self-adjusting based on user behavior.
Solution Approach 2:
The patent replaces manual mechanical camera control with an automated detection and control system that uses sensors to detect head orientation and automatically adjusts the virtual camera parameters, substituting manual operation with an automated sensing and control mechanism.
2Ease of operation
If automated camera rotation based on head orientation is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system continuously detects the user's head orientation using the detection means and uses this feedback to automatically adjust the virtual camera's line of sight. The control means receives real-time orientation data and dynamically adjusts camera parameters to maintain the object within the field of view, creating a closed-loop feedback system.
Solution Approach 2:
The goggle apparatus integrates multiple functions including head orientation detection, virtual camera control, and object tracking within a single device. The detection means serves multiple purposes by detecting both head orientation and object position, while the control means manages both camera rotation and object placement.

AI summary
An example of an image display system includes a goggle apparatus including a display section. A virtual camera and a user interface are placed in a virtual space. In accordance with the orientation of the goggle apparatus, the orientation of the virtual camera in the virtual space is controlled. For example, in a case where the line of sight of the virtual camera rotates in a left direction in a yaw direction and then reverses in a right direction, and when the amount of change in the right direction is greater than or equal to a threshold, the user interface is moved to the front of the virtual camera.
