Touchscreen Video Playback Control via Gesture Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video playback controls on touchscreens are not as precise as those using pointing devices, making it difficult to navigate and control video playback efficiently, especially for tasks like pausing, skipping forward or backward, and navigating to specific times.
Innovation Solution
A method and system for controlling video playback on touchscreens using tap, swipe, and press-and-hold gestures within a player window, allowing for pausing, skipping forward or backward, and navigating to specific times within a video by mapping gestures to video playback actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional video playback controls (progress bar, icons) are used on touchscreen, then video playback can be controlled, but the control precision and ease of operation deteriorate compared to pointing devices
Solution Approach 1:
The patent merges multiple control functions (play/pause, skip forward, skip backward, seek to position) into a unified gesture-based control system. Different gestures (tap, swipe left, swipe right, long press) are mapped to different playback actions, eliminating the need for separate icons and progress bar interactions. This integration maintains control precision while significantly improving ease of operation on touchscreen devices.
Solution Approach 2:
The patent replaces the mechanical pointing device system (mouse with cursor movement) with a touchscreen gesture system. Instead of requiring precise pointer movement to interact with small UI elements, users can perform intuitive gestures directly on the video display area. This substitution maintains control precision through gesture recognition while dramatically improving ease of operation by eliminating the need for separate control interfaces.
2Adaptability or versatility
If progress bar with draggable indicator is used, then video navigation is possible, but the operation becomes complex and less convenient on touchscreen
Solution Approach 1:
The patent extracts the navigation functionality from the traditional progress bar interface and integrates it directly into the video playback area through gesture recognition. Instead of requiring users to interact with a separate progress bar element, the video display itself becomes the control surface. Swipe gestures anywhere on the video area trigger navigation, simplifying the interface while maintaining full navigation capability.
Solution Approach 2:
The patent makes the video playback area universal by enabling multiple control functions within the same space. The same video display area responds to different gestures (tap for play/pause, swipe for skipping, long press for seeking) to provide comprehensive video navigation. This eliminates the need for separate control regions and icons, making the interface both adaptable and easy to operate.
3Adaptability or versatility
If multiple separate control icons are provided for playback functions, then comprehensive control is achieved, but the interface complexity increases
Solution Approach 1:
The patent merges multiple separate control icons and functions into a unified gesture-based system. Instead of displaying separate icons for play/pause, skip forward, skip backward, and seeking, the system uses gesture recognition on the video area itself to provide all these functions. This significantly reduces interface complexity while maintaining comprehensive playback control functionality.
Solution Approach 2:
The patent enables the video playback interface to serve itself by using the video display area as both the content area and the control surface. The video area automatically responds to gestures without requiring separate control regions or icons. This self-service approach eliminates unnecessary interface elements while providing comprehensive control functionality through intuitive gestures.

AI summary
Methods, systems and media for controlling playback of video using a touchscreen are provided. In some embodiments, the method comprises: causing video content to be presented in a player window of a screen of a touchscreen; detecting a first tap gesture within the player window; causing presentation of the video content to be paused; detecting a second tap gesture via the touchscreen; causing presentation of the video content to continue; detecting a left to right swipe gesture; causing a first portion of the video content that is later in time to be presented; detecting a right to left swipe gesture; causing a second portion of the video content that is earlier in time the video content that is currently being presented to be presented.
