Touch Screen Content Playback Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices lack a user interface for playing back multiple contents simultaneously due to limited performance, making it difficult to manage and display multiple content playback on a small screen.
Innovation Solution
A content playback apparatus featuring a touch screen, memory, and processor that allows users to display, move, and magnify multiple contents through touch inputs, enabling easy arrangement and playback on a limited screen by using a user interface with thumbnail images and a main area for content display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple contents are played back simultaneously on a mobile device, then content playback capability is improved, but user interface complexity increases
Solution Approach 1:
The user interface is segmented into distinct functional areas: a thumbnail image area for selecting contents and a main area for playback. This segmentation allows multiple contents to be managed through organized visual representation without overwhelming the user interface
Solution Approach 2:
The interface transitions from traditional linear navigation to a two-dimensional spatial arrangement where thumbnail images are positioned in a grid layout. Users can visually locate and select contents across the screen space, adding a spatial dimension to content selection that simplifies multi-content management
2Adaptability or versatility
If multiple contents are displayed on a small screen, then content selection capability is improved, but screen space utilization deteriorates
Solution Approach 1:
The screen is divided into two functional zones: a thumbnail image area occupying a portion of the screen for content selection, and a main area for active playback. This segmentation allows efficient use of limited screen real estate by dedicating specific spaces to different functions
Solution Approach 2:
Thumbnail images serve as visual copies or representations of the actual content. These scaled-down copies allow users to browse and select multiple contents simultaneously without requiring full-screen display of each content, thus preserving screen space while maintaining selection capability
3Measurement precision
If content playback size is magnified for better visibility, then viewing quality is improved, but available screen area for other contents deteriorates
Solution Approach 1:
The interface maintains clear spatial separation between the thumbnail selection area and the main playback area. When a user selects a thumbnail, the content plays in the dedicated main area, preventing interference with thumbnail visibility and selection capability
Solution Approach 2:
The system provides enhanced viewing quality in the main playback area through full-size content display, while accepting that this comes at the cost of reduced thumbnail area. This partial action approach optimizes viewing quality for the selected content while maintaining adequate space for content selection

AI summary
A content playback apparatus comprises a touch screen, a memory and a processor. The touch screen is configured to play back a plurality of contents and to detect a touch input for the contents. The memory is configured to store instructions to control a playback of the contents. The processor is configured to control the playback of the contents according to the instructions. The instructions include a display instruction for displaying playbacks of the plurality of contents in a predetermined size, a move instruction for moving, among the plurality of contents, a content according to the touch input, and a magnification instruction for, in response to said moving, magnifying a playback size of the moved content according to the touch input and displaying a playback of the content on the touch screen at the magnified playback size of the content.
