Four-Dimensional Coordinate System for Scrollable Display User Intent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems face ambiguity in accurately capturing user intent due to the ambiguity in screen coordinates when scrolling occurs, leading to inaccurate business decisions as different pixels are confused as the same point on the display screen.
Innovation Solution
The implementation of four-dimensional (4D) coordinates, comprising an x coordinate, a y coordinate, a z coordinate representing the scroll factor, and a time coordinate, allows for unambiguous identification and recording of user navigation, enabling accurate prediction of user intent by analyzing these coordinates and historical data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional two-dimensional screen coordinates are used to track user input, then the system is simple to implement, but accuracy deteriorates when scrolling occurs because different pixels are confused as the same point
Solution Approach 1:
The patent extends the traditional two-dimensional screen coordinate system by adding a scrolling dimension (z-coordinate representing scroll offset) and a time dimension (t-coordinate representing event timing), transforming it into a four-dimensional coordinate system. This dimensional expansion allows unique identification of pixels even when scrolling occurs, as the same screen position at different scroll offsets or times can be distinguished through their additional coordinate values.
2Measurement precision
If four-dimensional coordinates are implemented to uniquely identify pixels during scrolling, then measurement precision improves, but device complexity increases due to additional coordinate tracking
Solution Approach 1:
The patent segments the coordinate tracking system into distinct components: two spatial coordinates (x, y) for screen position, one scrolling coordinate (z) for scroll offset, and one time coordinate (t) for event timing. This segmentation allows each dimension to be tracked and processed independently, simplifying the overall complexity management while maintaining high precision in user intent identification.
3Adaptability or versatility
If scrolling is enabled for displaying contiguous information, then adaptability improves for handling large content, but reliability deteriorates due to coordinate ambiguity
Solution Approach 1:
The patent introduces a scrolling coordinate (z-coordinate) as an intermediary element that mediates between the display content and the coordinate system. This intermediary tracks the scroll offset and allows the coordinate system to maintain reliability even when scrolling occurs, as the scroll coordinate serves as a reference that disambiguates pixel positions across different scroll states.

AI summary
An information handling system receives information from an input pointer, obtains a first coordinate from the information with respect to a first direction of a display, obtains a second coordinate from the information with respect to a second direction of a display screen, and obtains a third coordinate from a scrolling value representative of an amount of scrolling of a contiguous presentation of displayable information for display of a portion of the contiguous presentation of displayable information within the display. The system also obtains a fourth coordinate representative of a time at which the first coordinate and the second coordinate are obtained, and provides an unambiguous record of a user's navigation of the contiguous presentation of displayable information based on the first coordinate, the second coordinate, the third coordinate, and the fourth coordinate.
