Camera-Based Game Input Using Figure Size Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports games, such as golf games, fail to accurately replicate the actions of real players due to reliance on touch operations, which are not truly representative of actual golfing actions, and require specialized hardware like gyro sensors, making them less accessible.
Innovation Solution
A program and system that utilize a player terminal with a camera to recognize and track a player's movements, determining operation inputs based on changes in the size and shape of the player within the image, allowing for more realistic game interactions without the need for specialized hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch operations are used for game input, then the operation method is simple and accessible, but the action does not truly reproduce real player movements
Solution Approach 1:
The patent replaces the mechanical touch operation system with an optical recognition system using a camera to capture and analyze player movements. The camera detects the player's figure in real-time and converts physical movements into operation inputs, substituting direct touch interaction with vision-based motion recognition.
Solution Approach 2:
The patent creates a visual copy of the player's physical movements through camera imaging and processes this copied visual information to generate game operations. By tracking the figure's position, size, and movement in the captured image, the system reproduces real player actions without requiring direct touch input.
2Measurement precision
If a game pad with gyro sensor is used, then the player actions are closer to real golf actions, but specialized hardware is required reducing accessibility
Solution Approach 1:
The patent makes the player terminal itself multi-functional by integrating camera-based motion recognition capabilities into a standard device. The terminal serves both as a display device and as a motion sensing device, eliminating the need for specialized game pads with gyro sensors while maintaining the ability to detect real player movements.
Solution Approach 2:
The patent substitutes the mechanical gyro sensor system with an optical camera-based detection system. Instead of using physical orientation sensing, the system captures visual information of the player's movements and derives operation inputs from changes in the figure's position and size in the image, achieving similar functionality with more accessible hardware.
3Measurement precision
If camera-based figure recognition is used, then real player actions are reproduced, but processing complexity increases
Solution Approach 1:
The patent extracts only the essential features needed for game operation from the full image data - specifically the figure's position, size, and movement trajectory. By focusing on these key parameters rather than processing complete image information, the system achieves accurate motion recognition while keeping processing complexity manageable.
Solution Approach 2:
The patent implements partial action by using only the necessary portion of image processing - tracking the figure's basic movement parameters - rather than performing complete image analysis. This selective approach provides sufficient accuracy for game operations without the computational burden of full image processing.

AI summary
A player terminal pertaining to an embodiment of the present invention functions as a device that provides a game to a player. Since the player terminal is configured to determine a player's operation input on the basis of the change in the size of a figure that is moved by the player in an image inputted via an in-camera, it is possible to determine the player's operation input on the basis of a player action in which the figure is moved farther away from or closer to the in-camera.
