Virtual Vehicle Auxiliary View for Simultaneous Front-Rear Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing virtual scene technologies, particularly in racing games, switching to a rear-view mirror function to display the virtual scene from the rear perspective can obstruct the user's view of the vehicle's front, reducing interaction efficiency and human-computer interaction effectiveness.
Innovation Solution
A method and apparatus that dynamically determine the target virtual vehicle based on relative distance and orientation, displaying an auxiliary picture with that vehicle as the focus using a virtual camera positioned relative to the first virtual vehicle, ensuring continuous and effective observation of both the vehicle's front and rear environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the virtual scene picture is directly switched to display from the rear perspective in full screen, then the user can observe the rear environment clearly, but the user cannot observe the picture in front of the virtual vehicle, reducing interaction efficiency
Solution Approach 1:
The display screen is segmented into multiple regions: a main display area showing the front view virtual scene picture, and an auxiliary display area showing the rear view auxiliary picture. This segmentation allows simultaneous display of both front and rear environments without fully switching perspectives, resolving the contradiction between observing rear environment and maintaining front view visibility.
Solution Approach 2:
Instead of switching between full-screen front view and full-screen rear view (temporal dimension), the solution displays both views simultaneously in different spatial regions of the screen. The auxiliary picture is positioned in a corner or edge region, creating a spatial arrangement that allows users to monitor rear environment while maintaining primary focus on front view, thus eliminating the need to switch perspectives.
2Loss of information
If the rear-view mirror function control is triggered to display auxiliary picture, then the rear environment becomes visible, but the complexity of the display system increases
Solution Approach 1:
The auxiliary picture is displayed in a localized region (auxiliary display area) rather than occupying the entire screen. This local display approach provides rear environment information where it is most needed (in the corner or edge of the screen) without complicating the overall display system architecture. The main display area remains unchanged, preserving simplicity while adding localized functionality.

AI summary
A method for displaying a picture in a virtual scene is provided. In the method, the virtual scene of a virtual environment is displayed. The virtual scene includes a first virtual vehicle. A target virtual vehicle of at least one second virtual vehicle is determined based on a distance between the first virtual vehicle and each of the at least one second virtual vehicle. Each of the at least one second virtual vehicle is located behind the first virtual vehicle in the virtual environment. An auxiliary picture is displayed in the virtual scene. The auxiliary picture of the target virtual vehicle is from a point of view associated with the first virtual vehicle.
