XR Avatar Interfaces Using Eye and Hand Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces for interacting with virtual and augmented reality environments are cumbersome, inefficient, and create a significant cognitive burden, often requiring multiple inputs and providing insufficient feedback, leading to errors and increased energy consumption in battery-operated devices.
Innovation Solution
The development of improved user interfaces that utilize a computer system with a display generation component, eye-tracking, hand-tracking, and tactile output generators to provide intuitive interactions, reducing the number of inputs needed and enhancing feedback, allowing for more efficient human-machine interaction by synchronizing user inputs with device responses.

Engineering Contradiction Analysis
1Ease of operation
If conventional user interfaces are used in virtual/augmented reality environments, then basic interaction functionality is provided, but the interfaces become cumbersome and create significant cognitive burden on users
Solution Approach 1:
The system provides immediate visual feedback by displaying a representation of the user's hand within the virtual environment, showing exactly which object is being manipulated and what actions are available. This real-time feedback eliminates cognitive burden by making the system state transparent and reducing the mental effort required to understand interaction possibilities.
Solution Approach 2:
The patent creates a virtual copy of the user's hand that exists within the augmented reality environment. This digital twin mirrors the physical hand's position and movements, allowing users to interact with virtual objects through natural hand gestures while receiving intuitive visual confirmation of their actions.
2Productivity
If multiple inputs are required to achieve desired outcomes, then precise control is possible, but the number of inputs increases and interaction becomes inefficient
Solution Approach 1:
The system combines multiple interaction functions into a single unified interface - the virtual hand representation. This single visual element provides simultaneous information about hand position, object selection, and available actions, eliminating the need for separate controls and reducing the number of inputs required to achieve desired outcomes.
Solution Approach 2:
The virtual hand representation serves multiple functions simultaneously: it acts as a positional indicator, an object selector, and an action trigger. This multi-functional design allows users to perform complex interactions through simple natural gestures, dramatically improving productivity while reducing interaction time.
3Loss of information
If detailed feedback is provided for user actions, then user understanding improves, but system processing requirements and energy consumption increase
Solution Approach 1:
The system provides feedback locally and contextually - displaying the virtual hand representation only in the relevant region of the augmented reality environment where interaction is occurring. This localized approach delivers comprehensive feedback information without requiring system-wide processing overhead, maintaining low energy consumption while preventing information loss.
