Slider Resolution Control via Two-Finger Gesture Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-based devices often present non-intuitive gestures for users, making it difficult for them to interact with devices via touch, particularly when precise selections are required, such as navigating through media content.
Innovation Solution
A method involving the detection of two-finger gestures to change the resolution of a slider element on a user interface, allowing users to switch between different resolution values for precise control, such as from 30 seconds to 1 second, enabling more accurate selection of time within media content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single finger gesture is used to interact with the slider, then the operation is simple, but the selection precision is insufficient
Solution Approach 1:
The interaction is segmented into two distinct phases: a first finger gesture for coarse selection and a second finger gesture for fine-tuning the selection. This segmentation allows the system to achieve high precision without requiring a single complex gesture, as the precision is accomplished through a simple second gesture that modifies the already-selected range.
Solution Approach 2:
The patent introduces a temporal dimension to the interaction by detecting a second finger gesture during a timeout period after the first gesture. This transforms the interaction from a single-dimensional (one gesture) to a multi-dimensional (sequence of gestures in time) approach, enabling precision enhancement without increasing the complexity of individual gestures.
2Measurement precision
If the slider resolution is increased for precise selection, then the selection accuracy improves, but the interaction time increases
Solution Approach 1:
The first finger gesture performs a preliminary action by selecting a initial time range or resolution level. This preliminary selection establishes a context that reduces the subsequent adjustment needed, allowing the second gesture to achieve precise selection quickly without requiring the user to perform a long, slow drag gesture from the beginning.
Solution Approach 2:
The slider resolution is made dynamic rather than static. The system automatically adjusts the resolution based on the detected finger gestures - using a first resolution for initial selection and switching to a second, higher resolution when a second gesture is detected. This dynamic adaptation allows the system to provide high precision only when needed, reducing overall interaction time.
3Adaptability or versatility
If multiple resolution values are provided for slider selection, then the precision control improves, but the device complexity increases
Solution Approach 1:
The second finger gesture serves multiple functions: it can be performed at any location on the display, works with any slider type, and can be executed regardless of the current slider position or resolution. This universal design allows the system to handle multiple resolution values and gesture variations without significantly increasing the complexity of the core gesture recognition mechanism.

AI summary
Methods and apparatus, including computer program products, are provided for finger gestures. In one aspect there is provided a method, which may include detecting a first finger gesture proximate to or making contact with a slider element presented on a user interface; detecting a second finger gesture proximate to or making contact with the user interface, the second finger gesture detected during a time period comprising a time when the first finger is proximate to or making contact with the slider; and changing a resolution of the slider from a first resolution value to a second resolution value, when the second finger gesture is detected.
