XR User Interface Feedback for Intuitive Hand Interactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interacting with virtual objects in XR environments is complex due to limited haptic feedback and difficulty in determining interaction opportunities, leading to unsatisfactory user experiences.
Innovation Solution
An interaction facilitation system that provides visual and audio feedback to enhance user interface interactions by modifying UI elements based on hand gestures, accentuating edges and portions of the user's hand, and generating cues to signify interaction opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual and audio feedback are provided to enhance user interface interactions, then user interaction experience is improved, but device complexity increases
Solution Approach 1:
The patent implements multiple feedback mechanisms including visual feedback (modifying UI elements, accentuating edges and portions of the user's hand, generating cues) and audio feedback to enhance user interaction. This directly addresses the contradiction by providing comprehensive feedback that improves ease of operation while managing device complexity through systematic implementation of feedback loops.
Solution Approach 2:
The interaction facilitation system acts as an intermediary between the user and the virtual objects, providing feedback and enhancing interactions. This mediator approach improves user interaction experience by bridging the gap between user actions and system responses, while the complexity is contained within the intermediary layer rather than propagating throughout the entire system.
2Ease of operation
If UI elements are modified based on hand gestures, then interaction intuitiveness is improved, but processing requirements increase
Solution Approach 1:
The patent dynamically modifies UI elements based on detected hand gestures, creating an adaptive interaction system. The UI elements change their properties (such as accentuation, position, or appearance) in response to user gestures, improving interaction intuitiveness. The processing requirements are managed by implementing dynamic adjustments only when needed, rather than continuous processing.
Solution Approach 2:
The system prepares and modifies UI elements in advance based on predicted or detected hand gestures, making interactions more intuitive. By performing preliminary actions such as pre-positioning or pre-modifying UI elements based on gesture detection, the system reduces the processing burden during actual interaction while maintaining high intuitiveness.
3Loss of information
If representation of user's hand is modified to signify interaction, then interaction clarity is improved, but rendering complexity increases
Solution Approach 1:
The patent modifies the representation of the user's hand by changing color, shading, or visual properties to signify interaction with UI elements. This provides clear visual feedback about interaction state, improving interaction clarity. The rendering complexity is managed by applying visual changes only to specific portions of the hand representation rather than entire scene re-rendering.
Solution Approach 2:
The system applies modifications to specific local portions of the hand representation (such as accentuating edges or specific fingers) rather than the entire hand or scene. This localized approach improves interaction clarity by highlighting relevant interaction points while minimizing rendering complexity by avoiding global scene modifications.

AI summary
A computer implemented method for facilitating user interface interactions in an XR environment is provided. The method incudes rendering a system UI and tracking a position of user's hand. The method further includes signifying an interaction opportunity by generating first feedback that modifies a UI element based on position of user's hand being within first threshold distance of the UI element or by generating second feedback that accentuates an edge of the system UI based on the position of user's hand being within second threshold distance of the edge. Furthermore, the method includes updating the position of the user's hand. The method further includes signifying interaction with the UI element by modifying location of representation of the user's hand, when the user's hand has interacted with the UI element or signifying interaction with the edge by generating third feedback that accentuates the portion of the representation that grabs the edge.
