Mobile Audio Device Screen Transition for DJ Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face limitations in screen size, leading to reduced operability and visibility when performing DJ preparation work, which involves complex music data manipulation and playback control, as they cannot display the same amount of information as computers.
Innovation Solution
An audio device with multiple playback units and a display controller that transitions between different screens for playback settings and controls, allowing users to manage both music data and output levels on a mobile terminal with intuitive operation elements, enhancing usability and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the amount of information displayed on the mobile terminal screen is reduced to accommodate the small screen size, then the visibility and operability are improved, but the functionality and completeness of DJ preparation work are deteriorated
Solution Approach 1:
The patent divides the DJ preparation work interface into multiple distinct screens: a first screen for playback settings of first music data, a second screen for playback settings of second music data, and a third screen for mixed playback control. This segmentation allows each screen to focus on specific functions with appropriate detail, making the interface more manageable on mobile devices while maintaining complete functionality across all operations.
Solution Approach 2:
The patent introduces a dimensional transition from displaying all information simultaneously on a single screen to navigating through multiple screens in sequence. By adding the dimension of screen transitions and contextual switching, the system provides comprehensive information and control options without requiring all data to be visible at once, thus adapting to mobile screen constraints while preserving full functionality.
2Area of stationary object
If the size of operation elements is reduced to fit the mobile terminal display, then the visibility and screen utilization are improved, but the ease of operation and accuracy of user input are deteriorated
Solution Approach 1:
The patent implements dynamic adjustment of operation element sizes based on the current screen context. When viewing detailed playback settings on the first or second screens, operation elements are displayed at normal size for ease of operation. When transitioning to the third screen for mixed playback control, the system automatically adjusts element sizes to accommodate the different operational requirements, ensuring optimal usability across all interfaces.
Solution Approach 2:
The patent applies different operation element characteristics to different regions and contexts within the interface. Critical operation elements on the first and second screens maintain larger sizes for precise input, while elements on the third screen are adapted to the mixed playback context. This local differentiation ensures that operation elements are appropriately sized for their specific functional requirements rather than using a uniform size throughout.
3Adaptability or versatility
If multiple screens are implemented to provide comprehensive DJ preparation functionality, then the completeness of playback control is improved, but the device complexity and interface complexity are deteriorated
Solution Approach 1:
The patent segments the complex DJ preparation interface into three distinct functional screens: a first screen for independent playback settings of first music data, a second screen for independent playback settings of second music data, and a third screen for coordinated mixed playback control. This segmentation organizes complexity by grouping related functions together, making the overall system more manageable while preserving complete functionality.
Solution Approach 2:
The patent introduces a screen transition mechanism as an intermediary between the individual playback screens and the mixed playback control. This transition system acts as a mediator that coordinates information and control between different screens, allowing users to navigate between contexts smoothly without experiencing the full complexity of all functions simultaneously, thus reducing perceived interface complexity.

AI summary
An audio device being a mobile terminal includes: first and second playback units; and a display controller that causes a display to display a screen including an operation element for accepting a user operation. The display controller includes: a first display controller to display a first screen including an operation element for the first music data; a second display controller to display a second screen including an operation element for the second music data; a third display controller to display a third screen including a third operation element including one of an operation element for both the first and second music data or an operation element for adjusting an audio output ratio, the third screen not including an operation element related to the playback setting; and a display transition controller to display the first-third screens so as to make transition between the first-third screens based on the user operation.
