Task-Based MRU Interface with Temporal Icon Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional user interfaces (UIs) that display a list of most recently used (MRU) objects are cumbersome and inefficient when dealing with applications that allow multiple tasks or types of files, as they either consume too much screen real estate or combine non-intuitive tasks, particularly in task-based UIs that handle diverse file types.
Innovation Solution
A graphical user interface featuring a primary icon representing a selected file with a temporal axis and secondary icons arranged in temporal order, allowing users to easily navigate and perform functions on recently used objects by selecting either the primary or secondary icons, with the UI maintaining a sequential ordering and intuitive task-based navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional menu-based MRU system is used to display recently used objects, then users can access recently used files, but the interface becomes cumbersome and inefficient when dealing with multiple file types and tasks
Solution Approach 1:
The interface is segmented into task-based categories (e.g., text documents, spreadsheets, presentations) with separate MRU lists for each task type. This allows users to access recently used objects within specific task contexts without being overwhelmed by a single comprehensive list, reducing interface complexity while maintaining ease of access.
Solution Approach 2:
The patent introduces a hierarchical dimension to the MRU interface, organizing recently used objects not just by recency but by task type and category. This multi-dimensional organization allows users to navigate to specific task areas and access relevant MRU objects, transforming the flat list into a structured, category-based system that reduces cognitive load.
2Ease of operation
If a task-based UI displays icons for each task type, then users can quickly identify tasks, but the interface consumes too much screen real estate
Solution Approach 1:
The patent merges the task identification function with the MRU object display by integrating task icons directly into the MRU list headers or section dividers. This consolidation allows users to identify task types and access recently used objects within the same visual space, eliminating the need for separate icon rows and reducing overall screen real estate consumption.
Solution Approach 2:
The task icons serve multiple functions simultaneously: they identify the task type, organize the MRU lists, and provide direct access to recently used objects within that task category. This multi-functionality reduces the need for separate UI elements, allowing comprehensive task identification without increasing screen real estate requirements.
3Adaptability or versatility
If multiple MRU lists for different task types are displayed separately, then users can access task-specific objects, but the interface becomes more complex and harder to navigate
Solution Approach 1:
The patent implements a nested structure where task-specific MRU lists are nested within a unified task-based interface framework. Each task category contains its own MRU list, but all categories are organized under a single navigable interface with consistent controls and layout patterns. This nesting allows task-specific access while maintaining overall interface simplicity through repetition of familiar interface patterns.
Solution Approach 2:
Each task category within the multi-task MRU interface employs locally optimized display and interaction patterns tailored to that task type, while maintaining consistency with the overall interface design language. This local quality allows each section to be optimized for its specific purpose without increasing global interface complexity, as users can apply the same interaction mental model across all task areas.

AI summary
A computing device includes a processor executing instructions to provide a graphical user interface displayed on a display device and for facilitating navigation through a collection of files stored in a storage device, the user interface including a primary icon displayed on the display device and representing a selected file, a temporal axis defined across at least a portion of the primary icon, and one or more secondary icons displayed on the display device, each representing a respective additional file, the secondary icons being positioned separate from the primary icon, wherein the secondary icons are arranged along the temporal axis in temporal order of each additional file represented by the secondary icons.
