Motion Effect Generation Apparatus for 4D Cinema

Solution Overview

Problem

Generating motion effects for 4D movies and similar experiences is time-consuming and costly, as it typically requires manual production by professional producers.

Innovation Solution

An apparatus and computer-readable medium that automatically generate optimal motion effects by processing raw motion information into segments, scaling, merging, and adding additional effects, using modules for segment generation, scaling, merging, and sustainment time calculation to produce continuous and irregular motion paths, and outputting control signals for motion apparatuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If motion effects are generated manually by professional producers, then the quality and realism of motion effects are improved, but the time and cost of production increase

Engineering Contradiction:

Improvequality of motion effectsVSAvoidproduction time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent uses camera motion information from video content as a template or copy to generate motion effects. Instead of manually creating motion effects from scratch, the system copies the camera's movement trajectory, velocity, and acceleration data and applies it to control motion apparatuses, thereby automatically reproducing realistic motion effects while significantly reducing production time and cost

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system enables motion effects to be generated automatically using the video content's own camera motion data. The camera motion information extracted from the video serves as the direct input for controlling the motion apparatuses, allowing the content to generate its own motion effects without requiring separate manual production processes

Inventive Principle:

Principle #25Self-service

3Reliability

If camera motion information is directly applied to motion apparatuses, then the realism of motion effects is improved, but the complexity of processing increases due to segmentation, scaling, and merging requirements

Engineering Contradiction:

Improverealism of motion effectsVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the continuous camera motion information into discrete segments based on motion characteristics such as velocity and acceleration changes. This segmentation allows the system to process different motion phases separately, applying appropriate scaling and merging operations to each segment, thereby maintaining motion realism while making the processing manageable through systematic breakdown

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transforms camera motion parameters (position, velocity, acceleration) into scaled motion apparatus control parameters. By changing the parameter representation and applying scaling factors based on the motion apparatus driving range, the system adapts the complex camera motion data to the specific requirements of motion apparatuses while preserving the essential motion characteristics

Inventive Principle:

Principle #35Parameter changes

AI summary

Disclosed are motion effect generation apparatuses and a computer-readable recording medium for program codes for implementing the motion effect generation apparatuses. The apparatus for generating a motion effect may comprise a segment generation part configured to divide a moving path of a camera or an object obtained from raw motion information into a plurality of segments; a scaling part configured to adjust a size of each of the plurality of segments according to a driving range of a motion apparatus; and a merging part configured to generate a motion path of the motion apparatus by merging the plurality of segments sizes of which are adjusted. Therefore, time and costs for producing 4D movies to which motion effects are applied can be reduced. In addition, they can be easily applied to 4D movie theaters, 4D rides, home theater equipment, and home game machines.
