Dynamic Camera Control for Multi-Display Gaming Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems that display images on multiple devices do not effectively utilize the multiple display devices, limiting player engagement and interaction.
Innovation Solution
A computer-readable storage medium with an information processing program that sets virtual cameras in a virtual space to display images on a stationary and portable display device, adjusting the visibility of objects based on the user's attitude, using methods such as zooming, blurring, or making objects transparent, to enhance player interaction between the devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If game space images are displayed on multiple display devices, then the player can view different character perspectives, but the multiple display devices are not effectively utilized and player engagement is limited
Solution Approach 1:
The patent implements dynamic image switching between display devices based on detected user gaze direction. The system transitions from static display assignment to dynamic adaptation, where the portable device display content changes according to whether the user is looking at the stationary or portable device, thereby effectively utilizing multiple displays and enhancing player engagement
2Loss of information
If the user is allowed to view images on both stationary and portable display devices simultaneously, then more game information is available, but the user cannot effectively interact with both devices at once
Solution Approach 1:
The patent implements periodic switching of display content based on user gaze detection. The system alternates between displaying different game space ranges on the portable device depending on whether the user is looking at the stationary or portable device, creating a rhythmic interaction pattern that allows full information access while maintaining effective interaction through sequential viewing
3Weight of moving object
If the portable display device is made smaller for portability, then it is easier to carry, but the display area is reduced limiting game space visibility
Solution Approach 1:
The patent divides the overall game space display across two devices: the stationary device displays one game space range while the portable device displays another range. This segmentation allows the small portable screen to show meaningful game information without requiring large display area, complementing the stationary device to provide complete game space coverage

AI summary
A pirate ship is displayed on a television being a stationary display device and on a terminal device being a portable display device. When the terminal device is held in a second attitude, the position and the angle of view of a first virtual camera are adjusted, and the pirate ship displayed on the television is zoomed out. When the terminal device is held in a first attitude, the position and the angle of view of the first virtual camera are adjusted and the pirate ship displayed on the television is zoomed in.
