Content Playback Apparatus Priority-Based Key Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with physical operation keys face operability issues when designating a partial region for expanded display of content during content sharing services, leading to user confusion and disrupted communication due to cumbersome key operations.
Innovation Solution
A contents playback apparatus that generates association information by prioritizing characteristic portions of a content and assigns operation keys to these portions, allowing for quick and accurate expansion of desired content regions during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical operation keys are used for designating characteristic portions in content sharing service, then the terminal can provide basic operation functionality, but the operability deteriorates due to cumbersome key operations and user confusion
Solution Approach 1:
The patent replaces physical operation keys with a touch panel interface that allows direct touching and sliding operations on the display screen. Users can directly touch the characteristic portion they want to expand on the screen, eliminating the need for complex physical key combinations and providing more intuitive operation.
Solution Approach 2:
The patent introduces a sliding operation mechanism as an intermediary between the user and the characteristic portion selection. By sliding along the boundary of the characteristic portion, the system provides visual feedback and precise selection control, reducing user confusion while maintaining ease of operation.
2Productivity
If repeated key operations are required to designate characteristic portions, then basic terminal functionality is maintained, but the time required for operation increases significantly
Solution Approach 1:
The patent performs preliminary identification of characteristic portions on the display screen before user selection. The system预先 marks or highlights characteristic portions, so users only need to touch or slide along the already-identified regions, eliminating the need for repeated exploration and reducing operation time.
Solution Approach 2:
The touch panel interface allows users to directly touch the characteristic portion they want to select, eliminating the need for repeated physical key operations. This direct manipulation significantly reduces the number of operations required and speeds up the selection process.
3Device complexity
If physical operation keys are used for expansion designation, then the terminal structure remains simple, but user confusion increases due to unclear positional relationships
Solution Approach 1:
The patent uses visual changes such as color highlighting or boundary line display to indicate the characteristic portion that will be expanded. When users slide or touch the screen, the system provides visual feedback showing which region will be expanded, making the positional relationship clear and reducing user confusion.
Solution Approach 2:
The sliding operation serves as an intermediary that provides continuous visual feedback during the selection process. As users slide along the boundary, the system displays information about the selected region, maintaining clarity of positional relationship while keeping the interface simple.

AI summary
A contents playback apparatus and the like are provided which allow a user to promptly designate a desired portion when displaying a part of a content in an expanded manner, and are thus excellent in operability. A contents playback apparatus includes an associating unit and a playback unit. The associating unit generates association information for a plurality of characteristic portions contained in a content by referring to priority orders of the respective characteristic portions relative to each other, the association information associating each of the characteristic portions individually with a predetermined operation key of an input device included in the apparatus in accordance with the priority orders. The playback unit plays back, in response to detecting an operation of an operation key during display of the content, the characteristic portion corresponding to the operation key in an expanded display mode, in accordance with the association information.
