Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation methods for digital content in virtual reality and augmented reality environments, such as grid-based Electronic Program Guides, become cumbersome and inefficient as the volume of digital content increases, due to limited space and the need for precise control, leading to frustration in accessing desired content.
Innovation Solution
A method of mapping objects to locations in a virtual space based on prominence values assigned according to distance from a reference location and physiological characteristics of the user, with priority levels determining the placement and visibility of objects, allowing for improved navigation and access to digital content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If grid-based EPG is used to display digital content, then the structure is simple and easy to implement, but the amount of information that can be displayed becomes very restricted and navigation becomes slow and cumbersome
Solution Approach 1:
The patent transitions from a two-dimensional grid-based EPG interface to a three-dimensional virtual space where content items are distributed in spatial dimensions. This allows significantly more content to be displayed simultaneously without increasing interface complexity, as the third dimension provides additional display real estate while maintaining simple navigation through natural movement.
Solution Approach 2:
The patent implements nested information display where detailed information about content items can be accessed through multiple levels of detail. Users can view an overview of content in the virtual space, then drill down into specific items for detailed information, similar to nested dolls. This allows the interface to display both summary information and detailed information without increasing the overall display complexity.
2Device complexity
If grid-based EPG is used to display digital content, then the layout is straightforward, but the number of items that must be displayed becomes very large and navigation becomes increasingly slow and cumbersome
Solution Approach 1:
By moving content from a two-dimensional grid to a three-dimensional virtual space, the system can accommodate a much larger number of content items while maintaining fast navigation. Users can pan, rotate, and zoom through the virtual space to quickly locate and access desired content, significantly improving navigation productivity.
Solution Approach 2:
The patent introduces dynamic navigation capabilities where the virtual space can respond to user actions in real-time. The camera can automatically pan to follow user movement, and the interface can dynamically adjust based on user interactions, making navigation faster and more adaptive compared to static grid-based systems.
3Device complexity
If traditional EPG navigation methods are used in virtual reality environment, then the method is simple to implement, but the precise level of control required becomes difficult to achieve and user frustration increases
Solution Approach 1:
The patent implements self-service navigation where the system automatically adapts to user actions and adjusts the display accordingly. The virtual camera automatically pans and zooms based on user movement, and the interface automatically highlights relevant content, reducing the need for precise manual control and improving ease of operation.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors user actions and adjusts the navigation and display in response. This feedback loop allows the system to learn user preferences and behaviors, providing increasingly precise and intuitive control over time, thereby reducing user frustration.

AI summary
A method of mapping an object to a location in a virtual space includes acquiring objects which are to be mapped to respective locations in a virtual space and assigning each respective location in the virtual space a prominence value representing the prominence of an object at the location when the virtual space is viewed by a user. The prominence value is assigned according to a distance of each location from a reference location in the virtual space and at least one physiological characteristic of a user. The method also includes mapping each object to a respective location in the virtual space according to a priority level associated with at least some of the objects and the prominence value assigned to each respective location in the virtual space.
