3D Environment Model Integration for Real-Time Motion Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaming systems lack the ability to seamlessly integrate real-world environments into interactive applications, limiting user interaction and immersion by relying on separate virtual game environments rather than actual user spaces.
Innovation Solution
A mobile depth camera captures a series of depth images to generate a dense 3D model of the environment, which is then incorporated into an interactive application, allowing for real-time user motion tracking and object recognition, enabling dynamic interaction within the game or application based on the real-world environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate virtual game environment is used, then the game can be fully controlled and standardized, but user immersion and interaction with real-world elements are reduced
Solution Approach 1:
The patent merges the virtual game environment with the real-world physical environment by projecting game elements onto the actual room and using the room's physical features as game boundaries and objects. This combines two previously separate environments into a unified hybrid system, allowing users to interact with virtual elements in their actual physical space.
Solution Approach 2:
The system uses cameras and projection devices as intermediaries to bridge the virtual and real worlds. The camera captures the real environment and feeds it to the game system, while the projector displays virtual game elements onto the physical space, acting as mediators that enable interaction between the two domains.
2Measurement precision
If a mobile depth camera is used to capture environment, then a dense 3D model can be generated, but the system complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary 3D modeling of the environment before the actual game play. The mobile depth camera captures and processes the room geometry in advance to create a stored 3D model, which is then used during gameplay for rapid object recognition and interaction without requiring real-time complex processing during the game itself.
Solution Approach 2:
The system segments the environment modeling process into distinct phases: initial scanning phase where the mobile camera captures comprehensive 3D data, and gameplay phase where the pre-built model is used for quick reference. This segmentation allows complex processing to occur only when necessary, reducing overall system complexity during active use.
3Ease of operation
If real-time motion tracking is implemented, then user interaction capability is improved, but processing time and computational resources increase
Solution Approach 1:
The system implements real-time feedback loops where the depth camera continuously tracks user motion, the game system processes this data to determine game actions, and the results are immediately projected back to the user. This closed-loop feedback enables natural interaction while maintaining real-time responsiveness through optimized processing of only essential motion parameters.

AI summary
Use of a 3D environment model in gameplay is described. In an embodiment, a mobile depth camera is used to capture a series of depth images as it is moved around and a dense 3D model of the environment is generated from this series of depth images. This dense 3D model is incorporated within an interactive application, such as a game. The mobile depth camera is then placed in a static position for an interactive phase, which in some examples is gameplay, and the system detects motion of a user within a part of the environment from a second series of depth images captured by the camera. This motion provides a user input to the interactive application, such as a game. In further embodiments, automatic recognition and identification of objects within the 3D model may be performed and these identified objects then change the way that the interactive application operates.
