List Preview Box Plot for Space-Constrained Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Space-constrained display devices limit the amount and type of data that can be legibly displayed, requiring users to scroll through lists to access details, which hides off-screen data and restricts understanding of the data distribution.
Innovation Solution
A computer-implemented method analyzes lists to generate previews or summaries by calculating statistical distribution data, such as quartile values, and visual representations like box plots, which are displayed alongside visible list items to provide a comprehensive overview of both on-screen and off-screen data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display device size is reduced to improve portability and energy efficiency, then the device becomes more portable and energy efficient, but the available display area is constrained limiting the amount of data that can be legibly displayed
Solution Approach 1:
A preview mechanism acts as an intermediary between the full data list and the limited display area. The preview provides statistical summaries (mean, median, mode, standard deviation) and visual representations (box plots, histograms) of off-screen data, allowing users to understand data distributions without viewing every individual item. This mediator enables effective data consumption within constrained space.
Solution Approach 2:
The system transforms raw data into different parameter representations suitable for compact display. Instead of showing all individual data points, it calculates and displays statistical parameters (mean, median, mode, standard deviation) and visual summaries. This parameter transformation allows comprehensive data understanding within limited display area.
2Loss of information
If scrolling is implemented to allow access to hidden list items, then users can access more data details, but the majority of data remains hidden off-screen limiting understanding of data distribution
Solution Approach 1:
The system performs preliminary analysis of the complete data list before display, calculating statistical parameters and generating visual previews of off-screen data. This preliminary action provides users with immediate insight into data distributions and patterns without requiring them to scroll through all items, making data comprehension easier while maintaining full data accessibility.
Solution Approach 2:
Statistical summaries and visual representations serve as intermediaries between the hidden off-screen data and the user's understanding. These previews bridge the gap by providing meaningful insights into data distributions without requiring direct viewing of all individual items, thus improving data comprehension while preserving access to complete data through scrolling when needed.
3Area of stationary object
If only segments of the list are displayed to fit space limitations, then the display device can show visible data, but the nature and distribution of off-screen data is occluded
Solution Approach 1:
Statistical previews act as intermediaries that reveal the nature and distribution of off-screen data without requiring additional display area. By calculating and displaying statistical parameters (mean, median, mode, standard deviation) and visual representations (box plots, histograms), the system communicates data distribution characteristics within the constrained display area, preventing information loss about off-screen data.
Solution Approach 2:
The system changes the representation parameters of off-screen data from individual item listings to statistical summaries and visual aggregations. This parameter transformation allows the display of comprehensive data distribution information within limited space, as statistical parameters convey essential distribution characteristics more efficiently than individual item listings.
Data Source
AI summary
Systems and methods for generating previews of list data in space constrained user interfaces are disclosed. In the available display area of a particular display device or user interface, a segment of a list of items are displayed. Values in the on-screen and off-screen portions of the list are analyzed and processed to generate previews of the list. One preview includes generating a box plot of the distribution of values in the list. An adaptively sized slider can then be generated relative to the box plot to indicate which part of the distribution is displayed in the list items that fit in the available display area. Another preview includes generating a composite row in the available display area that summarizes the data in one or more of the off-screen portions of the list. Such previews can include the sum or average of the values in the off-screen list items.
