Gesture-Based Video Clipping Control on Mobile Touchscreens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional button-based video controls are ineffective on mobile devices for navigating and creating video clips from live or pre-recorded video content, as they do not account for human factors and intuitive user interactions.
Innovation Solution
A gesture-based video clipping system using touch input components, where users can swipe with one, two, or three fingers to fast forward or rewind videos, with the direction and velocity of the swipe determining the interval and destination frame, allowing for intuitive selection and generation of video clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-based video controls are used on mobile devices, then the control interface is simple to implement, but the ease of operation deteriorates because small buttons do not work well on mobile devices
Solution Approach 1:
The patent replaces traditional mechanical button controls with gesture-based touch controls. Users swipe on the video player interface to navigate through video segments, eliminating the need for small physical or on-screen buttons. This substitution improves ease of operation on mobile devices while maintaining implementation feasibility through standard touch event handling.
2Ease of operation
If gesture-based controls are implemented to improve ease of operation, then the ease of operation improves, but the device complexity increases due to additional touch input handling
Solution Approach 1:
The video player interface serves multiple functions: it acts as both the video display area and the control interface. Gestures performed on the video area itself trigger navigation and clipping functions, eliminating the need for separate control buttons. This multi-functionality approach improves ease of operation while minimizing additional complexity by reusing the existing video display area for control purposes.
3Device complexity
If small buttons are used for video control on mobile devices, then the device complexity remains low, but the ease of operation worsens because small buttons are difficult to interact with
Solution Approach 1:
The patent transitions from zero-dimensional button presses to two-dimensional swipe gestures across the video interface. Users can swipe in different directions and distances to control video playback and create clips, providing more intuitive and easier operation on mobile devices while maintaining relatively low implementation complexity through standard touch event processing.

AI summary
System, method, and computer program product to generate a clip of a media file on a device having a touch input component, the media file comprising a plurality of segments, by outputting for display a first segment of the media file, responsive to receiving: (i) input indicating to generate the clip of the media file using the first segment, and (ii) a first swipe gesture on the touch input component: identifying a subset of segments, of the plurality, based on a direction of the first swipe gesture, the first subset of segments including a destination segment, and outputting for display each of the subset of segments, and responsive to receiving input selecting the destination segment as part of the clip of the media file, generating the clip of the media file, the media clip including each segment of the media file between the first and the destination segment.
