Video Playback Device Text List Hiding for Active Learning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for language learning, which display conversation texts and images with synchronized sounds, result in low learning effectiveness as users primarily listen and glance at answers, rather than actively engaging with the content.
Innovation Solution
A video playback device that stores sound-attached videos correlated with texts, allowing users to specify texts and hide the list to focus on playing the corresponding video segments, enabling separate study times for watching and listening, and offering repeat learning modes with silent intervals for text review.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users study by listening to sound while looking at its text simultaneously, then they can access both audio and visual information, but the learning effect is low because users primarily listen and glance at answers rather than actively engaging
Solution Approach 1:
The study process is divided into separate phases: first listening to the sound, then viewing the text. This segmentation prevents users from passively glancing at answers while listening, forcing active engagement during each phase and improving learning effectiveness.
Solution Approach 2:
The system implements periodic switching between sound playback and text display modes. Users first engage with audio content, then periodically switch to review text content, creating a rhythmic study pattern that enhances retention and active engagement compared to simultaneous passive consumption.
2Adaptability or versatility
If the list of texts is displayed during video playback, then users can reference texts while watching, but it distracts users and reduces focus on the video content
Solution Approach 1:
The text list is extracted from the video playback view and placed in a separate, switchable interface. During video playback, users can choose to hide the text list completely, eliminating visual distractions and enabling full focus on the video content while maintaining the option to access texts when needed.
Solution Approach 2:
The text list display is made dynamic and configurable during playback. Users can toggle the text list visibility on or off based on their current learning needs, allowing the interface to adapt between focused video viewing mode and reference mode without requiring full screen switches.
3Quantity of substance
If conventional devices display conversation texts and images with synchronized sounds, then they provide comprehensive learning materials, but users cannot separate study times for watching and listening
Solution Approach 1:
The learning materials are segmented into distinct audio and text components that can be accessed independently. Users can choose to study only audio, only text, or both in sequence, providing flexible study timing options while maintaining complete learning content availability.
Solution Approach 2:
The system provides multiple study modes within a single platform: audio-only mode, text-only mode, and sequential audio-then-text mode. This multi-functionality allows users to adapt the same comprehensive learning materials to different study schedules and preferences without requiring separate resources.

AI summary
A video playback device includes a sound-attached video storage unit, a text storage unit, a text list display control unit, a text specification unit and a sound-attached video portion playback control unit. In the sound-attached video storage unit, a sound-attached video is stored. In the text storage unit, texts for sounds of sound-attached video portions of the sound-attached video are stored in such a way as to be correlated with the respective sound-attached video portions. The text list display control unit controls to display the texts as a list. The text specification unit specifies a text in the displayed list as a specific text on the basis of a user operation. The sound-attached video portion playback control unit controls to hide the list and play a sound-attached video portion for the specific text.
