Motion Controller Time Synchronization for 4D Cinema
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motion code transmission techniques in 4D cinemas struggle with accurate synchronization of multiple seat motions with picture timing, leading to errors and disruptions due to high data requirements and network instability, resulting in low-resolution and imprecise motion experiences for users.
Innovation Solution
A system and method where a motion code corresponding to a time code is prestored before picture showing, and synchronized with a reference time from a central server, allowing the motion controlling device to adjust and maintain high-resolution motion control even during network instability, ensuring continuous and precise motion synchronization with the picture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion codes are transmitted in real-time streaming scheme, then motion can be synchronized with picture, but data transmission rate decreases and high-resolution motion cannot be transmitted
Solution Approach 1:
The motion code corresponding to each time code is prestored in the motion controller before picture showing starts. This preliminary storage of motion codes allows the system to avoid real-time transmission during picture showing, thereby maintaining high data transmission rates while ensuring accurate motion synchronization with the picture through pre-synchronized time codes.
2Productivity
If motion codes are transmitted in real-time streaming scheme, then motion control can be updated continuously, but network instability causes motion control to stop
Solution Approach 1:
Motion codes are prestored before picture showing starts, creating a buffer that continues operating even if network transmission fails during picture showing. This ensures motion control continuity and reliability without depending on real-time network stability.
Solution Approach 2:
The motion controller continues to execute prestored motion codes throughout the picture showing period, maintaining continuous motion control action even when network transmission is interrupted. This ensures the useful action of motion control never stops during the picture showing.
3Adaptability or versatility
If motion codes are transmitted in real-time streaming scheme, then motion can be adjusted dynamically, but synchronization error occurs between multiple motion controllers
Solution Approach 1:
Motion codes corresponding to specific time codes are prestored in each motion controller before picture showing. Since all controllers receive the same time-coded motion codes in advance, they execute synchronized motion without requiring real-time communication, eliminating synchronization errors between multiple controllers while maintaining adaptability through time-based coordination.

AI summary
Provided are a system and a method for controlling a motion using time synchronization between a picture and the motion, and more particularly, a motion code corresponding to a time code is prestored before showing the picture and the motion is controlled according to the prestored motion code when the picture showing starts while a current motion driving time is compared with a reference time of the picture and then synchronized to provide a high-resolution precision motion to a user while achieving accurate synchronization with the picture.
