3D Content Sharing Through Gaze And Hand Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with augmented and virtual reality environments are cumbersome, inefficient, and create a significant cognitive burden on users, often requiring multiple inputs and providing insufficient feedback, leading to errors and energy wastage, particularly in battery-operated devices.
Innovation Solution
The system employs improved user interfaces that reduce the number and nature of user inputs by using gaze and hand tracking, blurring or darkening the three-dimensional environment when not in focus, modifying content boundaries based on playback state, and enabling content sharing through movement towards other users, enhancing user-device interaction efficiency and reducing power consumption.

Engineering Contradiction Analysis
1Ease of operation
If conventional user interfaces are used in augmented reality environments, then users can interact with virtual elements, but the interaction becomes cumbersome and creates significant cognitive burden
Solution Approach 1:
The system automatically detects user gaze direction and hand gestures to identify intended interactions, eliminating the need for users to manually select or navigate through complex interface elements. The interface serves itself by interpreting natural human behaviors as commands, reducing cognitive burden while maintaining interaction capability.
Solution Approach 2:
The patent replaces traditional mechanical input devices (buttons, switches, keyboards) with optical sensing systems that detect gaze direction and hand gestures. This substitution allows users to interact with virtual elements through natural movements rather than manipulating physical controls, significantly improving ease of operation.
2Productivity
If multiple inputs are required to achieve desired outcomes, then precise control is possible, but interaction time increases and energy is wasted
Solution Approach 1:
The system continuously tracks user gaze and hand positions in advance, so when a user looks at a virtual element and performs a gesture, the interaction is already prepared and can be executed immediately. This eliminates the need for multiple sequential inputs and reduces the time users spend interacting, thereby conserving battery power.
Solution Approach 2:
The patent maintains continuous tracking of user gaze and hand gestures throughout the interaction process, ensuring that the system is always ready to respond to user intent. This continuous monitoring eliminates gaps between inputs and reduces total interaction time, improving productivity while managing energy consumption efficiently.
3Reliability
If insufficient feedback is provided for performing actions, then the interface remains simple, but user errors increase
Solution Approach 1:
The system provides real-time visual feedback by highlighting virtual elements when the user gazes at them and showing hand gesture recognition status. This feedback mechanism confirms to users that their actions are being detected and interpreted correctly, reducing errors while maintaining intuitive interaction. The feedback is integrated seamlessly into the augmented reality display, not adding extra complexity.
