Focused Card Navigation for Interactive TV Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces for modern information systems, such as interactive television and personal computers, are inefficient due to the need for users to repeatedly navigate through numerous options, often by pressing buttons or scanning icons, which is slow and inconvenient.
Innovation Solution
A focused navigation system where cards representing options are displayed successively in a central area of the user interface, allowing rapid recognition and selection without the need for repeated button presses, using a remote control or other input devices, and enabling high-speed display of options within the user's recognition threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users navigate through numerous options by repeatedly pressing buttons or scanning icons, then the user interface can display all available options, but the navigation speed becomes slow and operation becomes inconvenient
Solution Approach 1:
The system dynamically transitions from a static grid of icons to a dynamic sequential display of cards. Instead of requiring users to manually scan and select from multiple static icons, the system automatically cycles through options in sequence, making the navigation process adaptive and responsive to user needs.
Solution Approach 2:
The system maintains continuous display of navigation options through sequential card presentation. Rather than requiring discrete button presses for each option, the system continuously cycles through available options in a smooth sequence, eliminating gaps in the navigation process and reducing user effort.
2Adaptability or versatility
If the user interface displays all available options, then users have access to numerous choices, but the time required to locate and select desired options increases
Solution Approach 1:
The system segments the navigation process into discrete sequential steps, with each step presenting a specific option as a card. This segmentation allows the system to manage numerous options in an organized, manageable sequence rather than displaying all options simultaneously, reducing the time required to locate desired options.
Solution Approach 2:
The system performs preliminary action by pre-organizing and pre-displaying options in a sequential sequence before the user needs to make a selection. This allows the system to prepare and present options in an optimized order, reducing the time users need to spend locating and selecting desired options.
3Device complexity
If conventional interfaces display options as icons in rows and columns, then the interface structure remains simple, but the complexity of navigating through numerous identical icons increases
Solution Approach 1:
The system applies local quality by transforming the uniform grid of identical icons into a sequential presentation where each option is displayed as a distinct card with unique visual characteristics. This local differentiation makes each option easily distinguishable and selectable, reducing the complexity of navigation while maintaining simple overall interface structure.
Data Source
AI summary
A sequence of cards is stored that graphically represents available options within an information system. In addition, supplemental information related to at least one card may be obtained. In response to a single user action, the sequence of cards is successively displayed within a focus area of the user interface. When a card having supplemental information is displayed, the supplemental information is also displayed, either on or near the card. In response to a subsequent user action, the successive display is discontinued to display a particular card representing a selected option.
