Gesture Touch Inputs for Video Control on Touchscreens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices with touchscreens face challenges in providing intuitive controls for video playback, particularly in rewinding and fast forwarding, due to the difficulty in navigating small screens and interpreting touch inputs.
Innovation Solution
Implementing gesture touch inputs such as swiping gestures on the touchscreen to control video playback, where rightward or leftward swipes rewind or fast forward the video, with the speed of the swipe determining the frame interval and display of a frame carousel, allowing concurrent display of multiple frames in lateral motion.

Engineering Contradiction Analysis
1Length of moving object
If traditional touch controls are used on small touchscreen displays, then device portability is maintained, but video navigation precision deteriorates
Solution Approach 1:
The patent segments the video navigation process into distinct gesture types (tap, swipe, flick) with different functions. Taps pause/play, swipes navigate forward/backward, and flicks enable rapid scrolling. This segmentation allows each gesture to be optimized for its specific purpose, improving navigation precision without requiring a larger screen.
Solution Approach 2:
The patent introduces motion dynamics as an additional dimension to touch input interpretation. By detecting swipe distance, flick velocity, and gesture duration, the system transforms a two-dimensional touch surface into a multi-dimensional control interface, enabling precise video navigation despite the limited physical screen size.
2Adaptability or versatility
If more video control functions are added to touchscreen interface, then video playback functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically detects and interprets gesture intentions based on motion characteristics. A flick gesture automatically triggers rapid frame scrolling without requiring the user to manually select speed or duration parameters. The system self-adjusts navigation behavior based on the detected gesture type, maintaining ease of operation while providing comprehensive video control functionality.
Solution Approach 2:
The patent changes the parameter space of touch input by incorporating motion velocity, swipe distance, and gesture duration as control parameters. A hard swipe navigates to the next frame, while a flick gesture scrolls through multiple frames at variable speeds. This parameter expansion enables diverse video playback control functions while maintaining intuitive operation through natural hand movements.
3Ease of operation
If gesture motion detection is implemented for video control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The gesture detection system serves multiple functions: it detects tap positions for pausing, swipe directions for navigation, and flick velocities for rapid scrolling. A single motion detection mechanism handles all video control operations, avoiding the need for separate physical buttons or controls for each function. This universal approach improves ease of operation while minimizing the increase in device complexity.

AI summary
In general, this disclosure describes novel techniques for controlling video content on a computing device, such as a mobile computing device. For example, a computing device may execute a media application that provides a video output to a presence-sensitive screen of the computing device. During execution of the media application, the presence-sensitive screen may receive a gesture touch input that has motion with respect to the presence-sensitive screen. The computing device may then rewind or fast forward the video output based at least in part on the gesture touch input. The computing device may display, during the rewinding or fast forwarding of the video output, a plurality of frames of the video output concurrently on the presence-sensitive screen in lateral motion corresponding to the rewinding or fast forwarding.
