Variable Scrubbing Rate Navigation for Touch Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for navigating through content on electronic devices with touch-sensitive surfaces are cumbersome and inefficient, leading to a significant cognitive burden and increased energy consumption, particularly in battery-operated devices.
Innovation Solution
A computer-implemented method and graphical user interface that utilizes a progress icon to move within content at a variable scrubbing rate, where the scrubbing rate decreases as the user moves their finger across the touch-sensitive surface in a direction perpendicular to the progress icon, allowing for faster and more efficient navigation through content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fixed-rate scrubbing methods are used, then the interface is simple to implement, but the navigation efficiency is low and cognitive burden is high
Solution Approach 1:
The patent implements dynamic scrubbing rate adjustment based on the user's finger movement speed across the touch-sensitive surface. As the user drags their finger faster, the content playback speed increases proportionally, allowing efficient navigation through large portions of content. This dynamic adaptation resolves the contradiction by making the system responsive to user intent without requiring complex menu selections or fixed-rate limitations.
Solution Approach 2:
The system changes the scrubbing rate parameter in real-time based on the velocity of the user's finger movement. By mapping finger movement speed to content playback speed, the system enables fast navigation when needed while maintaining simplicity in the interaction model. The parameter transformation from physical movement velocity to digital playback rate directly addresses the efficiency-complexity tradeoff.
2Loss of time
If conventional fixed-rate scrubbing methods are used, then energy consumption is predictable, but the navigation time is excessive and battery life is reduced
Solution Approach 1:
The system dynamically adjusts energy consumption patterns by matching playback speed to user urgency. When users need to scan through content quickly, the system consumes more energy to enable higher scrubbing rates. This dynamic energy allocation reduces overall navigation time and extends battery life by avoiding prolonged low-speed scrubbing, resolving the time-energy tradeoff in favor of user productivity.
3Ease of operation
If conventional fixed-rate scrubbing methods are used, then the system is easy to control, but the user experience is tedious and satisfaction is low
Solution Approach 1:
The system serves itself by automatically determining the appropriate scrubbing rate based on the user's finger movement characteristics. No additional controls or settings are needed - the system observes the drag velocity and self-adjusts the playback speed accordingly. This self-service approach maintains ease of operation while dramatically improving scrubbing speed and user satisfaction.

AI summary
A method is performed by an electronic device with a display and a touch-sensitive surface. The method includes: displaying a progress icon that indicates a current position within a first piece of content, displaying a multi-purpose content navigation icon; while providing the first piece of content: detecting a first contact at a first location that corresponds to the multi-purpose content navigation icon; while continuing to detect the contact at the first location, moving the current position within the first piece of content at a predefined scrubbing rate; and, in response to detecting movement of the contact that includes a first component of movement in a direction that corresponds to movement on the display parallel to the first predefined direction, moving the current position within the first piece of content at a variable scrubbing rate that varies monotonically as the first component of movement increases.
