Screen Soccer System Using Footstep and Gravity Center Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen soccer systems fail to simulate the actual experience of running, which is a significant aspect of soccer, making it difficult to provide a realistic game experience, especially in indoor settings where space is limited and weather conditions require indoor physical education activities.
Innovation Solution
A screen soccer system that includes a system server with a data transceiver, running information processor, image output part, and kicking information processor, which receives and analyzes footstep and gravity center movement information from sensing devices to convert it into running and kicking image information, providing a realistic running and kicking experience by displaying this information on an image output device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If screen soccer system only simulates kicking motion, then device complexity is reduced, but realism of soccer game experience deteriorates
Solution Approach 1:
The system divides soccer game simulation into separate functional modules: kicking motion detection (via pressure sensors and cameras), running motion detection (via footstep sensors), ball trajectory calculation, and image generation. Each module handles specific aspects independently, reducing overall system complexity while maintaining comprehensive realism.
Solution Approach 2:
The system uses multiple sensing devices (pressure sensors, footstep sensors, cameras) that can detect various types of motions (kicking, running, jumping). These multi-functional sensors capture different aspects of soccer gameplay, enabling realistic simulation without requiring separate specialized devices for each action.
2Reliability
If running motion is added to screen soccer system, then realism of soccer game experience is improved, but device complexity increases
Solution Approach 1:
The system merges running motion detection (footstep sensors) with kicking motion detection (pressure sensors and cameras) into a unified simulation framework. Both types of motion data are integrated into the same image generation process, creating a comprehensive running-kicking simulation without requiring entirely separate systems.
Solution Approach 2:
The system introduces an intermediary processing layer that receives data from multiple sensing devices (footstep sensors, pressure sensors, cameras), processes running and kicking motions separately, and then integrates them into unified game images. This intermediary layer manages complexity by handling different motion types through a standardized interface.
3Adaptability or versatility
If indoor space is used for physical education, then weather dependency is reduced, but available activity space is reduced
Solution Approach 1:
The system creates a virtual copy of outdoor soccer gameplay through generated images showing ball trajectories, running paths, and kicking actions. This virtual representation replicates the outdoor soccer experience within the limited indoor space, allowing students to engage in soccer-like activities without requiring actual outdoor场地.
Solution Approach 2:
The system transitions the soccer game from physical three-dimensional space to two-dimensional visual representation through generated images. By displaying top-down views, side views, and trajectory visualizations, the system provides comprehensive soccer gameplay information in a compressed spatial format suitable for indoor environments.
Data Source
AI summary
A screen soccer system and method are disclosed. The screen soccer system includes a system server including a data transceiver, a running information processor, an image output part, and a kicking information processor. The running information processor receives footstep information of user in real time from a first footstep sensing device. The image output part transmits the running image information to an image output device through the data transceiver. The data transceiver receives gravity center movement information of the user transmitted from a second footstep sensing device. The kicking information processor analyzes and converts the gravity center movement information, the kicking motion information, and the soccer ball kicking information into kicked ball image information regarding a kicked ball path. The image output part transmits the kicked ball image information to the image output device through the data transceiver.
