Gesture-Controlled Video Playback Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to follow movements in video content, such as home training or dance lessons, as existing display devices do not automatically adjust playback to synchronize with the user's actions, leading to difficulties in maintaining pace and accuracy.
Innovation Solution
A display device equipped with sensors and a processor that detects user gestures and adjusts the video content playback, pausing, speeding up, or moving the reproduction point to match the user's movements, allowing for real-time synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video content is reproduced at fixed speed without automatic adjustment, then device complexity is reduced, but user satisfaction and ability to follow movements deteriorates
Solution Approach 1:
The system continuously detects user gestures via sensors and uses this feedback to automatically adjust video playback speed and position, creating a closed-loop control system that adapts to user needs in real-time
Solution Approach 2:
The display device autonomously monitors user performance through gesture detection and self-adjusts playback parameters without requiring manual intervention from the user
2Ease of operation
If manual control devices are used to pause or resume video, then reproduction control flexibility is improved, but ease of operation deteriorates due to additional equipment and steps
Solution Approach 1:
The gesture detection and video control functions are merged into a single integrated system, eliminating the need for separate control devices by using the display device's own sensors to capture gestures and control playback
3Adaptability or versatility
If video playback speed is fixed, then device complexity is reduced, but adaptability to user needs deteriorates
Solution Approach 1:
The video playback system transitions from a static fixed-speed mode to a dynamic adaptive mode where playback speed and position automatically adjust based on real-time gesture detection results
Solution Approach 2:
The system dynamically changes playback parameters (speed, position) based on detected user gestures, allowing flexible adaptation to different user paces and needs

AI summary
A display device may include: a display; an image input unit configured to obtain video content; a detector including at least one sensor; and a processor which may be configured to execute at least one instruction. The processor may be configured to, by executing the at least one instruction, detect a gesture of a user based on a result of detection by the at least one sensor while the video content is reproduced, and control the reproduction of the video content such that at least one frame corresponding to the detected gesture among a plurality of frames included in the video content is displayed on the display.
