Artificial Reality Gesture Control for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artificial reality devices often pose challenges for individuals with audio and visual impairments, as they rely on visual and audio prompts for setup and interaction, which can be inaccessible to those with disabilities.
Innovation Solution
The implementation of gesture recognition capabilities in artificial reality devices using machine learning models to identify and execute user commands through hand gestures, allowing users to interact and set up devices without relying solely on visual or auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If artificial reality devices use visual and audio prompts for setup and interaction, then the user experience is enhanced for able-bodied users, but accessibility for users with visual or auditory impairments deteriorates
Solution Approach 1:
The system implements a universal control interface that works for all users regardless of ability. Gesture recognition serves as a universal input method that replaces or supplements traditional visual and audio-based interactions, allowing users with various impairments to operate the device effectively. The camera-based gesture system provides a common language for interaction that transcends sensory limitations.
Solution Approach 2:
The patent introduces gesture recognition as an intermediary interaction mode between the user and the artificial reality system. Instead of directly relying on visual or audio prompts that may be inaccessible, the system uses camera-captured hand gestures as a mediator to translate user intent into device commands. This intermediary layer bridges the gap for users with sensory impairments.
2Ease of operation
If gesture recognition is added to artificial reality devices, then accessibility for users with impairments is improved, but device complexity increases
Solution Approach 1:
The system uses the device's existing camera hardware to capture gestures, eliminating the need for specialized sensors or additional input devices. The camera, already present for other purposes, is repurposed for gesture recognition, allowing the system to serve itself and reducing overall system complexity despite adding functionality.
Solution Approach 2:
The camera serves multiple functions: traditional visual processing for augmented reality and gesture recognition for accessible control. By making the camera multi-functional, the system avoids adding dedicated hardware for gesture input, thereby managing complexity while expanding capability.
3Adaptability or versatility
If multiple interaction modes are provided, then adaptability for different user needs is improved, but ease of operation deteriorates due to increased complexity
Solution Approach 1:
The system dynamically adapts its interaction mode based on user needs and context. Users can switch between traditional visual/audio prompts and gesture-based control as needed. The system detects and responds to different input types flexibly, allowing simple operation in each mode while providing adaptability across modes.
Solution Approach 2:
The patent creates a universal control system where gestures serve as a common language that works across different scenarios and user types. This unified approach simplifies the user experience by providing consistent interaction patterns regardless of which sensory modality is used, making the system both adaptable and easy to operate.

AI summary
Systems and methods are provided for operating an artificial reality device using gestures. In various exemplary embodiments, an artificial reality device may receive information initiating a gesture recognition mode via the artificial reality device, and cause a camera associated with the artificial reality device to operate in the gesture recognition mode. The artificial reality device may further receive at least one image of a gesture captured by the camera and identify and evaluate the gesture. The gesture may be indicative of a user command. The artificial reality device may also execute the user command, and may generate feedback confirming execution of the user command.
