Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with virtual and augmented reality environments are cumbersome, inefficient, and place a significant cognitive burden on users, often requiring multiple inputs and providing insufficient feedback, leading to energy wastage, particularly in battery-operated devices.
Innovation Solution
The system utilizes gaze and hand tracking to modify visual characteristics of displayed content, zoom based on user gaze, and differentiate media item display based on depth information, providing intuitive and efficient interaction through reduced inputs and improved visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input methods (touchscreen, keyboard, mouse) are used to interact with virtual objects, then users can control the system, but the interaction becomes cumbersome and requires multiple inputs increasing cognitive burden
Solution Approach 1:
The patent replaces mechanical input methods (touchscreen, keyboard, mouse) with gaze-based interaction. Users control virtual objects by looking at them rather than physically touching or clicking, eliminating the need for multiple sequential inputs and reducing cognitive burden while maintaining control capability
Solution Approach 2:
The system automatically selects and activates virtual objects based on user gaze direction. When a user looks at a virtual object, the system automatically brings it into focus or activates it without requiring manual selection, making the interaction self-service and more intuitive
2Productivity
If gaze tracking is implemented to reduce input requirements, then interaction efficiency improves, but energy consumption increases
Solution Approach 1:
Instead of continuously processing gaze data, the system employs periodic sampling of gaze positions at intervals. This allows the gaze tracking component to function while consuming significantly less energy than continuous processing would require, balancing interaction efficiency with power consumption
Solution Approach 2:
The system pre-loads virtual object information and maintains readiness to respond to gaze changes. By preparing the system state in advance, it can respond quickly to gaze-based commands without requiring continuous high-energy processing during actual interaction
3Reliability
If multiple inputs are required to achieve desired outcome, then system control is precise, but interaction time increases wasting energy
Solution Approach 1:
The patent merges multiple interaction steps into a single gaze-based action. Instead of requiring separate actions for selection, activation, and parameter adjustment, the system combines these functions so that a single gaze fixation can trigger the desired outcome, reducing interaction time while maintaining control precision
4Device complexity
If insufficient feedback is provided during interaction, then system response is simple, but user understanding of connection between inputs and responses deteriorates
Solution Approach 1:
The system provides visual feedback by highlighting or emphasizing the virtual object that the user is gazing at. This feedback mechanism helps users understand which object is currently selected or active, improving their comprehension of the input-output connection without requiring complex feedback systems
