Corner Gesture UI Gating for Artificial Reality Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial reality systems lack intuitive and efficient methods for users to interact with user interface elements within virtual environments, often requiring physical buttons or complex gestures, which can be cumbersome and inaccessible for users with motor skill limitations.
Innovation Solution
The system generates and renders graphical user interface elements in response to specific gestures detected by image capture devices, such as hand movements forming defined angles or configurations, allowing users to invoke UI elements without physical buttons and accommodating single-handed or arm-based gestures, enhancing accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical buttons or complex gestures are used for UI interaction, then device functionality is achieved, but ease of operation deteriorates and accessibility is reduced
Solution Approach 1:
The patent replaces physical buttons and complex mechanical gesture systems with simple hand gesture recognition. The image capture device detects hand positions and configurations (such as corner-based gestures where fingers form specific angles) to trigger UI elements, eliminating the need for physical controls and simplifying the interaction mechanism while maintaining full device functionality.
2Ease of operation
If simple gestures are used for UI interaction, then ease of operation improves, but reliability of gesture detection may deteriorate
Solution Approach 1:
The patent enhances gesture detection reliability by focusing on specific local characteristics of hand gestures, particularly corner-based configurations where fingers form distinct angles. The system identifies unique geometric properties (such as right angles formed by index finger and thumb) and uses these localized features as reliable triggers for UI interactions, ensuring accurate detection even with simple overall gesture forms.
3Adaptability or versatility
If traditional UI interaction methods are used, then system stability is maintained, but adaptability to user needs deteriorates
Solution Approach 1:
The patent implements a universal gesture recognition system that can detect and respond to multiple different hand configurations (corner-based gestures, various finger arrangements) to trigger different UI elements. This multi-functional approach allows a single image capture and gesture detection system to handle diverse interaction needs, providing adaptability across different user requirements while maintaining a unified system architecture.

AI summary
An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. The artificial reality system includes an image capture device, a head-mounted display (HMD), a gesture detector, a user interface (UI) engine, and a rendering engine. The image capture device captures image data representative of a physical environment. The HMD outputs artificial reality content. The gesture detector identifies, from the image data, a gesture including a configuration of a hand that is substantially stationary for at least a threshold period of time and positioned such that an index finger and a thumb of the hand form approximately a right angle. The UI engine generates a UI element in response to the identified gesture. The rendering engine renders the UI element as an overlay to the artificial reality content.
