Wireless Motion Capture for Real-Time Film Pre-Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pre-visualization methods for films are inefficient and costly, as they often require multiple attempts to capture a director's vision, involving extensive resources and time, and motion capture technologies are cumbersome and expensive, limiting artistic freedom and incurring significant financial and time expenses.
Innovation Solution
A system combining motion capture sensors, virtual digital rendering, and a controller for real-time navigation within a three-dimensional virtual space, allowing directors to generate pre-visualizations according to their preferences, using components like MAYA and CRYENGINE 3 for detailed rendering and wireless motion capture suits for on-set choreography.

Engineering Contradiction Analysis
1Manufacturing precision
If traditional pre-visualization methods (comics, storyboards, frame sketches) are used, then the process is simple and requires minimal equipment, but the accuracy and ability to capture director's vision is poor, requiring multiple iterations
Solution Approach 1:
The patent uses motion capture technology to capture real actor movements and performances, creating accurate digital copies of physical actions. This allows directors to see realistic pre-visualizations that accurately represent the final film product, eliminating the need for multiple iterative attempts with traditional storyboards and sketches.
Solution Approach 2:
The patent replaces traditional manual pre-visualization methods (artists drawing comics and storyboards) with automated motion capture and computer-generated imagery systems. This substitution enables rapid generation of accurate pre-visualizations without requiring multiple manual iteration cycles.
2Manufacturing precision
If motion capture technology is used, then the accuracy and realism of pre-visualization improves, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts only the essential motion capture functionality needed for pre-visualization, separating it from full-scale production motion capture systems. By using wireless sensors and simplified capture volumes, the system removes unnecessary complexity while maintaining the core capability of capturing realistic human movement for pre-visualization purposes.
Solution Approach 2:
The patent employs cost-effective wireless motion capture sensors instead of expensive tethered systems with reflective suits. These simpler, more affordable sensors provide sufficient accuracy for pre-visualization work, reducing both equipment cost and system complexity while maintaining realistic motion capture capability.
3Measurement precision
If tethered motion capture systems are used, then measurement precision is high, but ease of operation and artistic freedom are reduced due to physical constraints
Solution Approach 1:
The patent transitions from static, tethered motion capture systems to dynamic, wireless systems that allow free movement. The wireless sensors enable actors and directors to move without physical constraints, maintaining high measurement precision while significantly improving ease of operation and artistic freedom during pre-visualization sessions.
Solution Approach 2:
The patent changes the fundamental parameter of motion capture from tethered to wireless operation. This parameter change eliminates physical constraints on movement while maintaining measurement precision through advanced sensor technology and signal processing, thereby enhancing artistic freedom and operational ease.
4Manufacturing precision
If extensive motion capture equipment and facilities are deployed, then the quality of captured footage improves, but the cost and setup time increase dramatically
Solution Approach 1:
The patent segments the motion capture system into portable, modular wireless sensor units that can be quickly deployed and configured. This segmentation allows the system to be set up rapidly in various locations without requiring extensive facility preparation, reducing both setup time and on-set expenses while maintaining pre-visualization quality.
Solution Approach 2:
The patent replaces complex, facility-intensive motion capture infrastructure with portable wireless sensor systems. This substitution eliminates the need for extensive equipment deployment and facility setup, dramatically reducing setup time and on-set expenses while maintaining the quality necessary for accurate pre-visualization.
