Card-Based Game Camera Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional video games face challenges in providing intuitive control over the position and direction of both characters and virtual cameras, leading to difficulties in achieving natural and desired camera angles during gameplay.
Innovation Solution
A game apparatus and method that utilize a card disposition system, card detector, character controller, and virtual camera controller to allow players to intuitively control the position and direction of characters and virtual cameras by detecting card movements, enabling circular movement of the camera around the character and changing camera angles based on card operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the virtual camera control is automatically carried out by causing it to exactly follow a behavior of the player character or by switching to any one of a plurality of points in accordance with a position of the player character, then the control system is simple, but the player cannot achieve natural and desired camera angles during gameplay
Solution Approach 1:
The patent introduces a card as an intermediary object between the player and the camera control system. The player operates the card on a card disposition system, and the card detector detects the card's position and direction to control both the character and the virtual camera. This intermediary card-based interface provides intuitive control while maintaining system manageability through dedicated detection and control modules.
2Ease of operation
If the control of the virtual camera is performed by an operation of a joystick, a button or the like disposed on a game pad, then the control system is straightforward, but it is difficult to perform the control of the virtual camera by an intuitive operation of a player
Solution Approach 1:
The patent replaces the traditional mechanical joystick and button system with a card-based operation system. Instead of using physical mechanical inputs on a game pad, the player manipulates a card on a card disposition system, and the card detector (using optical or other detection methods) translates the card's position and direction into control signals for the virtual camera and character, providing a more intuitive interface.
3Ease of operation
If the position and direction of the character is controlled by card position and direction, then the character control is intuitive, but the camera control becomes complex when trying to achieve natural camera angles
Solution Approach 1:
The patent segments the control system into distinct functional modules: a card detector that detects card position and direction, a character controller that controls character position and direction based on card input, and a virtual camera controller that independently controls camera position and direction based on card input and character position. This segmentation allows differential control where the same card input can produce different control outcomes for character and camera, enabling natural camera angles while maintaining intuitive character control.

AI summary
To apply a certain change to a displayed image while controlling a position and direction of a character and a virtual camera. In changing a direction of a character card without changing its position, when the direction changes slowly a direction of a character changes according to change direction of the character card, and a visual point of a virtual camera moves circularly according to the change direction of the character. When the direction of the character card is changed fast only the visual point moves circularly and the direction of the character does not change.
