Mobile Apparatus Rubbing Gesture Video Preview Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices require multiple touches to preview video content, making the process inconvenient and inefficient.
Innovation Solution
A mobile apparatus and control method that detects a rubbing gesture on a thumbnail to display a preview of video content, adjusting the time interval and positional spacing of preview images based on the gesture's speed and direction, allowing for seamless preview functionality with minimal user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple touches are required to preview video content, then the preview function can be activated, but the ease of operation deteriorates due to the need for multiple steps
Solution Approach 1:
The system dynamically responds to different touch gestures (single touch, rubbing gesture, scrolling gesture) to activate preview functionality. By detecting the specific motion pattern and velocity of the touch, the system determines whether to display preview images, thereby reducing the need for multiple discrete touches while maintaining reliable preview activation
Solution Approach 2:
The rubbing gesture detection mechanism serves as an intermediary between the user's touch input and the preview display. By introducing this intermediate gesture recognition layer, the system can trigger preview functionality through a single continuous rubbing motion rather than requiring multiple separate touches, thus improving ease of operation while preserving the reliability of preview activation
2Device complexity
If preview images are displayed with fixed time interval and positional spacing, then the display is simple, but the adaptability deteriorates as it cannot respond to different user interaction speeds
Solution Approach 1:
The system dynamically adjusts the time interval between preview images and their positional spacing based on the detected rubbing gesture velocity. When the user rubs faster, the system increases the time interval and spacing to match the quicker interaction pace. This dynamic adaptation allows the display to respond flexibly to different user interaction speeds while maintaining manageable control complexity through automated parameter adjustment
Solution Approach 2:
The system implements feedback by continuously monitoring the rubbing gesture velocity and using this information to adjust display parameters in real-time. The detected gesture speed feeds back into the display control logic, which then modifies the time interval and positional spacing of preview images accordingly, creating an adaptive system that responds to user interaction patterns

AI summary
A mobile apparatus control method that detects a gesture to provide a preview is provided. The method includes displaying a thumb-nail of video contents on a touch screen, detecting a rubbing gesture on the thumb-nail of the video contents displayed on the touch screen, and displaying the preview of the video contents on the touch screen when the rubbing gesture is detected.
