3D Gesture Interface State Transition via Spatial Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces rely on tactile methods, which can be limiting in terms of engagement and disengagement, particularly in three-dimensional spaces, and lack efficient non-tactile interaction mechanisms for controlling devices.
Innovation Solution
A non-tactile three-dimensional user interface system utilizing 3D sensing technology to recognize gestures, such as push and wave motions, to transition between states, enabling users to engage and disengage control of the interface through 3D coordinates captured by a sensing device, with visual feedback for user interaction and disengagement cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tactile interface devices (keyboard, mouse, joystick) are used, then device control functionality is achieved, but user engagement and disengagement efficiency deteriorates
Solution Approach 1:
The patent replaces tactile mechanical input devices (keyboard, mouse, joystick) with a non-tactile 3D sensing system that captures hand gestures in three-dimensional space. The sensing device detects hand position, orientation, and motion trajectories to recognize gestures such as pushing motions for engagement and specific hand movements for disengagement, eliminating the need for physical contact with traditional input devices.
Solution Approach 2:
The patent transitions from two-dimensional tactile interfaces to three-dimensional gesture recognition. The sensing device captures hand gestures in 3D space, analyzing position, orientation, and motion trajectories across multiple dimensions. This dimensional expansion enables more intuitive and efficient user engagement and disengagement through natural hand movements rather than confined tactile interactions.
2Productivity
If traditional tactile interfaces are used, then device control is achieved, but interaction efficiency in three-dimensional spaces deteriorates
Solution Approach 1:
The patent replaces traditional tactile interfaces with a 3D sensing-based gesture recognition system that operates in three-dimensional space. The sensing device captures hand gestures and the system recognizes patterns such as pushing motions along motion trajectories, enabling efficient interaction without physical contact and with full three-dimensional movement capability.
3Reliability
If gesture recognition based on body part shape and position is used, then gesture classification is achieved, but false positive recognition increases
Solution Approach 1:
The patent establishes predefined engagement and disengagement regions in three-dimensional space before gesture recognition occurs. The system determines whether a detected hand gesture originates from within the engagement region to validate it as a genuine engagement gesture, and similarly checks if disengagement gestures originate from the disengagement region. This preliminary spatial validation reduces false positives by ensuring gestures occur in contextually appropriate locations.
4Ease of operation
If non-tactile 3D user interface is implemented, then user experience is enhanced, but system complexity increases
Solution Approach 1:
The patent extracts and separates distinct functional regions (engagement region and disengagement region) within the three-dimensional sensing space. By defining these separate regions and associating them with specific gestures, the system simplifies the interpretation of complex 3D gesture data. The sensing device captures comprehensive hand motion information, but the system processes it by focusing on whether gestures occur in predefined regions, reducing processing complexity while maintaining enhanced user experience.

AI summary
A method, including receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture including a first motion in a first direction along a selected axis in space, followed by a second motion in a second direction, opposite to the first direction, along the selected axis. Upon detecting completion of the gesture, the non-tactile 3D user interface is transitioned from a first state to a second state.
