Touchscreen Scrolling Control via Continuous Cursor Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scrolling methods on touchscreen devices cause user fatigue due to frequent swiping and tapping, which can lead to discomfort and soreness, especially when consuming content like digital comic books or graphic novels on small screens.
Innovation Solution
A method and apparatus that allow users to control scrolling by sensing continuous cursor movement along a first axis, enabling progression through graphical content in panel mode without lifting their finger, and switching between page and panel modes using distinct user inputs, such as double-taps or prolonged touches, to reduce repetitive gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional swipe and tap gestures are used for scrolling on touchscreen devices, then content navigation is achieved, but user fatigue and discomfort occur due to frequent repetitive gestures
Solution Approach 1:
The system detects a prolonged touch gesture ( exceeding threshold duration) as a preliminary action to switch from page mode to panel mode. This preliminary gesture sets up a state where subsequent scrolling requires fewer and larger gestures, reducing the frequency of repetitive finger movements and thereby addressing user fatigue while maintaining navigation efficiency
Solution Approach 2:
The system dynamically switches between two operational modes: page mode for general navigation and panel mode for detailed viewing. This dynamic adaptation allows the interface to optimize scrolling behavior based on user needs, reducing the frequency of repetitive gestures in panel mode where content is already magnified and fewer scroll events are needed
2Productivity
If page mode is used to display multiple panels per screen, then navigation speed is improved, but detail visibility in individual panels is reduced
Solution Approach 1:
The system implements dynamic mode switching between page mode and panel mode based on user gesture patterns. In page mode, multiple panels are visible for fast navigation. When a prolonged touch is detected, the system transitions to panel mode, displaying a single enlarged panel for detailed viewing. This dynamic adaptation resolves the contradiction by allowing the user to switch between navigation speed and detail visibility as needed
Solution Approach 2:
The system adds a temporal dimension to the interaction model by using gesture duration as a distinguishing factor. Short swipes trigger page-level navigation, while prolonged touches trigger panel-level magnification. This temporal differentiation allows the same physical space to serve dual purposes: fast navigation when needed and detailed inspection when needed, resolving the speed versus detail visibility contradiction

AI summary
Methods and apparatus control scrolling of graphical content arranged in a sequence of panels by a computer responsive to a user input device. A method includes sensing, by the computer, a direction and length of continuous cursor movement along a first axis of the user input device. The method further includes progressing display of the graphical content through the sequence of panels based on the direction and length of the continuous cursor movement. The user input device may be a touchscreen or a touchpad and the computer may determine the cursor location based on a one-finger touch registered by the user input device. The method enables the user to scroll through panels of graphical content using a reduced number of finger taps and smaller movements, reducing hand and finger fatigue.
