Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interacting with augmented and virtual reality environments are cumbersome, inefficient, and place a significant cognitive burden on users, requiring multiple inputs and lacking sufficient feedback, leading to energy wastage in battery-operated devices.
Innovation Solution
The system employs enhanced user interfaces that utilize hand and eye tracking, along with tactile and audio output, to reduce the number and complexity of user inputs by providing manipulation indicators, contextual menus, and distance-based object movement, enabling more intuitive interaction with three-dimensional environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input methods are used to interact with virtual objects, then basic functionality is achieved, but user interaction becomes cumbersome and inefficient
Solution Approach 1:
The system displays manipulation indicators that provide real-time feedback to users about how to manipulate virtual objects. These indicators show the type of manipulation possible and guide user actions, reducing cognitive burden while maintaining simple interaction patterns.
Solution Approach 2:
The patent introduces an intermediary indicator system between the user and the virtual object manipulation. This mediator translates complex manipulation concepts into simple visual cues that guide users through the interaction process without requiring them to understand the underlying complexity.
2Ease of operation
If multiple inputs are required to achieve desired outcomes, then precise control is achieved, but cognitive burden increases and interaction becomes tedious
Solution Approach 1:
The system performs preliminary actions by automatically determining the type of manipulation based on the virtual object's properties and the user's gaze direction. This eliminates the need for users to explicitly specify manipulation parameters, reducing cognitive burden while maintaining precise control.
Solution Approach 2:
The system serves itself by automatically selecting appropriate manipulation types and parameters based on the virtual object's characteristics and the user's intent. This self-service capability reduces the number of inputs required from users while maintaining interaction precision.
3Measurement precision
If detailed manipulation control is provided, then precision is achieved, but interaction becomes complex and error-prone
Solution Approach 1:
The system applies different levels of manipulation detail based on the specific virtual object and context. Simple objects receive basic manipulation indicators, while complex objects receive more detailed guidance. This localized approach maintains precision without universally increasing complexity.
4Use of energy by moving object
If traditional interaction methods are used, then basic functionality is achieved, but energy consumption increases due to extended interaction time
Solution Approach 1:
The system maintains continuous useful action by providing uninterrupted manipulation guidance through visual indicators. Users can continuously interact with virtual objects without pausing to figure out manipulation methods, reducing total interaction time and energy consumption.
