Volumetric Zone Gesture Tracking for Interactive Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive display systems rely on two-dimensional cameras, which struggle to reliably isolate and track user hand movements, leading to poor data quality and limiting the ability to provide gesture-based interactions, forcing users to rely on physical input methods.
Innovation Solution
The system processes three-dimensional information to identify user hand movements within a defined space, displaying on-screen icons that can interact with digital objects, using volumetric zones to determine interaction capabilities and activation levels, allowing for accurate gesture-based control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional cameras are used to capture user interactions, then the device complexity is reduced, but the measurement precision of hand movements deteriorates
Solution Approach 1:
The patent transitions from two-dimensional camera capture to three-dimensional depth mapping by introducing volumetric zones. The system divides space into foreground and background regions using depth thresholds, enabling accurate separation of user hands from the background and precise tracking of hand movements in three-dimensional space.
2Measurement precision
If three-dimensional depth mapping is implemented to improve hand isolation, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent segments the three-dimensional space into distinct volumetric zones (foreground zone and background zone) based on depth thresholds. This segmentation allows the system to isolate hand movements from the background by assigning pixels to different zones, simplifying the processing of depth data while maintaining high measurement precision.
3Reliability
If volumetric zones are used to determine interaction capabilities, then the reliability of gesture recognition improves, but the loss of information increases
Solution Approach 1:
The patent implements feedback by continuously monitoring hand position relative to volumetric zones and providing real-time visual indicators on the display. The system adjusts interaction states based on hand presence in specific zones, creating a feedback loop that enhances gesture recognition reliability while preserving spatial information through dynamic visual feedback.

AI summary
Systems and methods for processing gesture-based user interactions within an interactive display area are provided. The display of one or more virtual objects and user interactions with the one or more virtual objects may be further provided. Multiple interactive areas may be created by partitioning an area proximate a display into multiple volumetric spaces or zones. The zones may be associated with respective user interaction capabilities. A representation of a user on the display may change as the ability of the user to interact with one or more virtual object changes.
