Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with virtual and augmented 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 waste, particularly in battery-operated devices.
Innovation Solution
Implementing computer systems with improved interfaces that utilize gaze tracking, hand tracking, and touch-sensitive displays to reduce the number and complexity of user inputs, providing enhanced visual and tactile feedback, and enabling direct touch interactions in three-dimensional environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional user interfaces are used for virtual and augmented reality environments, then the system can provide basic interaction functionality, but the interface becomes cumbersome, inefficient, and error-prone requiring excessive inputs
Solution Approach 1:
The system provides real-time visual feedback by displaying a gaze indicator that shows the user where the system detects their attention is directed. This feedback loop allows users to understand the connection between their inputs (gaze) and system responses, reducing the cognitive burden and number of inputs needed to achieve desired outcomes in virtual and augmented reality environments
Solution Approach 2:
The patent introduces a gaze indicator as an intermediary element that mediates between the user's attention and the virtual/augmented reality interface. This intermediary visual element bridges the gap by showing users what the system perceives as their focus point, enabling more intuitive and efficient interaction without requiring multiple complex inputs
2Adaptability or versatility
If multiple inputs are required to achieve desired outcomes, then the system can perform complex operations, but the cognitive burden on the user increases significantly
Solution Approach 1:
By providing visual feedback through the gaze indicator, the system reduces cognitive burden by making the interaction model transparent. Users can see exactly where their gaze input is registered and what actions are available, eliminating the need to mentally track complex input sequences and reducing cognitive load while maintaining operation versatility
3Productivity
If conventional interaction methods are used, then the system can process user inputs, but the interaction takes longer than necessary wasting energy
Solution Approach 1:
The system continuously tracks and displays the user's gaze position in advance, preparing the interface state before explicit selection actions are taken. This preliminary visualization of attention and available actions allows users to make faster decisions and reduce interaction time, thereby reducing energy consumption in battery-operated devices
