Touchscreen Persistent Field for Rapid Gesture Repetition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touchscreen devices face challenges in precision and efficiency when performing multiple swiping gestures due to limited screen size, requiring extensive finger movement and time for scrolling through content, and existing solutions like scroll bars compromise display space for information.
Innovation Solution
A method where a user can activate a persistent field on the touchscreen after completing a control movement, allowing for repeated transformations without re-executing the movement, enabling intuitive and rapid repetition of scrolling, zooming, or rotating actions by simply tapping the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple swipe gestures are performed to scroll through content on a limited-size display, then the user can access more information, but the time required and finger movement distance increase significantly
Solution Approach 1:
The system performs preliminary action by automatically returning the display to the starting position after each swipe gesture completes. This eliminates the need for the user to manually return their finger to the starting point, thereby reducing the time and effort required for subsequent swipe gestures while maintaining full access to the content area.
2Measurement precision
If the finger must return to the starting point after each swipe gesture, then precision can be maintained, but the distance covered becomes unnecessarily large
Solution Approach 1:
Instead of requiring the user's finger to return to the starting position, the system inverts the approach by automatically returning the display content to the starting position. This maintains measurement precision for the next gesture while dramatically reducing the physical distance the user's finger must travel.
3Measurement precision
If scroll bar is provided as an alternative to swiping, then precision and control are improved, but the display space for information is reduced
Solution Approach 1:
The invention extracts the precision control function from the traditional scroll bar interface and integrates it directly into the swipe gesture mechanism. By detecting swipe speed and automatically adjusting scroll behavior, the system maintains high scrolling precision while eliminating the need for separate scroll bar elements, thereby preserving maximum display area for information.

AI summary
The invention relates to a method for influencing the presentation of pictorial information (31-37) displayed on a display device (22) of an information technology device (20) by means of a transformation of the pictorial information (31-37), said transformation being specified by the user, wherein the transformation comprises at least one translation and/or rotation and/or compression and/or elongation of the pictorial information (31-37) and the method has the step of carrying out a first transformation according to a control movement which is carried out by the user and which triggers the transformation. The invention is characterized by the following steps: providing a field (F1-F7) on the display device (22) such that the field (F1-F7) remains activatable for at least one defined or definable period of time (TA) when the control movement is completed; and carrying out an additional transformation which is identical to the first transformation as soon as the field (F1-F7) is activated by the user. The invention further relates to a corresponding information technology device (20).
