Content Scrubbing Gesture Recognition on Touchscreens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices require multiple steps for users to initiate scrubbing through content items, which can be inefficient and increase power consumption.
Innovation Solution
Implementing a content item scrubbing technique that allows scrubbing through a content item by detecting a swipe input on a touch-sensitive surface, enabling scrubbing even outside the scrubber bar and continuing after liftoff, while maintaining consistent presentation and animation size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with the scrubber bar to scrub through content items, then scrubbing functionality is achieved, but the number of interaction steps increases and power consumption rises
Solution Approach 1:
The patent extracts the scrubbing functionality from the constrained scrubber bar region and enables it across the entire display area. Users can now perform scrubbing gestures anywhere on the screen, not just within the scrubber bar bounds, thereby reducing interaction steps and improving ease of operation
Solution Approach 2:
The display area is given multiple functions: it serves both as the content display region and as the input region for scrubbing gestures. This multi-functionality eliminates the need for a separate scrubber bar interaction, reducing the steps required to initiate scrubbing
2Measurement precision
If the scrubber bar is made more prominent for easier scrubbing, then scrubbing precision improves, but the display area for content is reduced
Solution Approach 1:
The patent applies different qualities to different regions: the entire display area responds to scrubbing gestures with appropriate precision, while the content display area remains maximized. The system detects gesture position and duration to determine scrubbing intent, providing accurate scrubbing control without requiring a prominent scrubber bar
Solution Approach 2:
The patent adds temporal dimension to the scrubbing interaction by using gesture duration and movement patterns to disambiguate between scrolling and scrubbing gestures. This allows the system to achieve scrubbing precision without requiring additional spatial elements like a larger scrubber bar
3Ease of operation
If scrubbing requires touchdown outside the scrubber bar, then ease of operation improves, but risk of unintended activation increases
Solution Approach 1:
The system provides feedback through gesture analysis, using touch duration, movement speed, and gesture pattern to determine whether the user intends to scroll or scrub. This feedback mechanism allows touchdown anywhere on the display while maintaining reliable discrimination between different gesture intents
Solution Approach 2:
The system dynamically adjusts its interpretation of gestures based on real-time characteristics such as touch duration and movement patterns. By making the gesture recognition dynamic rather than static, the system can accommodate flexible input locations while maintaining activation accuracy

AI summary
In some embodiments, a content item scrubbing technique includes, while displaying a user interface including a content item, receiving, via one or more input devices, an input for scrubbing through the content item, wherein the input for scrubbing through the content item includes a first part directed to a region corresponding to a portion of the user interface that does not include a scrubber bar, and a second part including movement in the region, and in response to receiving the input for scrubbing through the content item, and in accordance with a determination that the input for scrubbing through the content item satisfies one or more first criteria, scrubbing through the content item in accordance with the movement in the region.
