Image Generation System Movement Boundary Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Game devices using image sensors for motion-based inputs face issues with unintended object movement when extracting operator motion, leading to uncomfortable and frustrating gameplay experiences.
Innovation Solution
An image generation system that acquires image and motion information from an image sensor, controls an object's movement within a defined area, and limits the object's movement to prevent unintended motion beyond set boundaries, ensuring intuitive and smooth gameplay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion information is used to control object movement, then operation intuitiveness is improved, but object may move beyond intended area causing unintended motion
Solution Approach 1:
The patent applies preliminary anti-action by establishing a movement limiting boundary before object movement occurs. The object control section proactively prevents the object from moving beyond the designated area by comparing the object's position with the boundary and correcting any excessive movement, thereby counteracting the potential harmful effect of unintended motion while preserving intuitive operation control
2Ease of operation
If motion-based control is implemented, then operation simplicity is improved, but unintended object motion occurs
Solution Approach 1:
The patent converts the potentially harmful effect of excessive motion input into a beneficial feature by using the movement limiting boundary as a corrective mechanism. When the object tends to move beyond the intended area, the boundary acts as a virtual wall that reflects or stops the object, transforming what would be an error into a controlled feature that maintains operation simplicity while preventing harmful unintended motion

AI summary
An image generation system includes an image information acquisition section that acquires image information from an image sensor, a motion information acquisition section that acquires motion information about an operator based on the image information from the image sensor, an object control section that moves an object in a movement area based on the motion information about the operator, and an image generation section that generates an image displayed on a display section. The object control section limits movement of the object so that the object does not move beyond a movement limiting boundary set in the movement area even when it has been determined that the object has moved beyond the movement limiting boundary based on the motion information.
