Navigation Visual Indicators for Context Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in navigating through display data on small screens with limited user input, such as mobile devices, as they struggle to maintain context while panning and zooming, often losing track of their location within the data due to limited movement and lack of visual feedback.
Innovation Solution
A navigation application that overlays visual indicators like grid lines and shading on the display to divide the data into sections, providing animated movements that indicate navigation operations and help users understand their location within the data, even when navigating to areas not currently visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display size is reduced for portability, then the device becomes more portable, but the user cannot see enough context to understand their location within the data
Solution Approach 1:
The display is divided into multiple sections using visual indicators (grid lines, shaded regions, highlighted areas). These sections represent different portions of the data, allowing users to understand their current location relative to the overall data structure even when viewing only a small portion on a portable device
Solution Approach 2:
Visual indicators serve as intermediaries between the limited display area and the larger data set. These indicators (grid lines, shaded regions, highlighted areas) provide contextual information about the user's location without requiring the entire data set to be visible on the small screen
2Measurement precision
If the user pans and zooms multiple times to see details, then the user can see detailed information, but the user loses track of their location within the overall data
Solution Approach 1:
The system provides continuous visual feedback during navigation operations. When the user pans or zooms, the visual indicators (grid lines, shaded regions) move and transform to show the user's new location relative to the overall data structure, preventing loss of context during detailed viewing
Solution Approach 2:
Visual indicators are established before the user begins navigation. The grid lines and shaded regions are pre-configured to divide the display into sections that correspond to portions of the data, so that as the user pans or zooms, the indicators automatically update to maintain location context without requiring additional user actions
3Device complexity
If the user interface provides limited input options for navigation, then the device remains simple, but the user cannot efficiently navigate through large amounts of data
Solution Approach 1:
The visual indicators automatically update and reconfigure themselves based on the user's navigation actions. When the user pans or zooms, the system self-adjusts the grid lines and shaded regions to reflect the new view, eliminating the need for complex interface elements to manually manage context

AI summary
Navigating display data (e.g., large documents) on an electronic display is described in which a first set of visual indicators are layered over the portion of the portion of data displayed on the electronic display. The user selects a particular navigation task, which selection signal is received by the navigation application. The navigation application determines a section of interest based on the particular navigation task selected and layers a second set of visual indicators over the portion of the display data defined by all of the sections other than the section of interest. The navigation application then animates movement of the display data and both sets of visual indicators on the electronic display according to the particular navigation task selected.
