3D Display Gesture Sensitivity Control for Z-Axis Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional display devices struggle to effectively sense and respond to user gestures along the z-axis, limiting user interaction and convenience, especially when dealing with applications having varying depth ranges and multiple objects in a single display.
Innovation Solution
The implementation of a sensor and controller system in electronic devices that adjusts gesture sensitivity based on the type of application, position, or attributes of objects, allowing for dynamic movement distances of pointers and objects in three-dimensional space, enabling more intuitive user interface interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture sensitivity is increased to allow larger movement distances for gestures, then user convenience is improved and extensive hand movement is reduced, but the precision of gesture control deteriorates
Solution Approach 1:
The patent applies dynamics by making the gesture sensitivity adjustable rather than fixed. The controller dynamically changes the gesture sensitivity based on the detected gesture type, allowing the system to optimize between user convenience and control precision for different interaction scenarios. This is achieved through the controller's ability to select from multiple sensitivity levels and apply them in real-time during gesture recognition.
Solution Approach 2:
The patent implements parameter changes by varying the gesture sensitivity parameter according to the specific gesture being performed. The system detects different gesture types (e.g., hand orientation, movement pattern) and adjusts the sensitivity parameter accordingly, transforming a static control system into one that adapts its parameters based on operational conditions to resolve the contradiction between ease of operation and precision.
2Adaptability or versatility
If gesture sensitivity is adjusted according to application type and object attributes, then the variety of user interfaces is increased and contextual accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a gesture recognition system that serves multiple applications and contexts through a single unified controller. The controller is capable of handling various gesture types and adjusting sensitivity for different application scenarios (e.g., 3D navigation, image processing, video playback) without requiring separate dedicated systems for each function, thus increasing adaptability while managing complexity.
Solution Approach 2:
The system implements self-service by automatically detecting the current application context and object attributes, then autonomously selecting the appropriate gesture sensitivity level without requiring manual user configuration. The controller monitors the operational state and adjusts parameters automatically, allowing the system to serve itself in optimizing its own performance across different contexts.
3Ease of operation
If the movement distance of pointer and objects is increased in proportion to gesture movement, then user convenience is improved, but the precision of object selection deteriorates
Solution Approach 1:
The patent resolves this contradiction by dynamically adjusting the proportionality factor between gesture movement distance and pointer/object movement distance. Rather than using a fixed ratio, the controller adaptively changes this scaling factor based on the gesture type, target object distance, and contextual parameters, allowing large movements for navigation while maintaining precision for selection tasks.
Solution Approach 2:
The system applies local quality by implementing different movement proportionality rules for different spatial regions and interaction contexts. When the pointer is far from the target, a larger movement proportion is applied for convenience; when approaching the target, the proportion is reduced to enhance selection precision. This localized adjustment of movement characteristics resolves the contradiction between ease of operation and selection precision.

AI summary
According to the present invention, disclosed is an electronic device having a three-dimensional display, comprising a sensor obtaining information about a gesture's motion; a three-dimensional display displaying a pointer and/or an object moving in three-dimensional space according to the gesture's motion; and a controller checking applications in execution, determining a movement distance of the pointer and/or the object in proportion to a movement distance of the gesture by taking account of gesture sensitivity selected according to the type of the checked application, and controlling the display to move the pointer and/or the object as much as the determined movement distance.
