Playlist Graphic Objects for Intuitive Music Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices lack intuitive methods for alerting users to music reproduction information and controlling multimedia playback, making it difficult for users to navigate and interact with music playlists effectively.
Innovation Solution
An electronic apparatus with an audio output unit, a display unit, and a controller that outputs audio information and graphic objects linked to songs, allowing for intuitive display of playlist information and control through graphical representations, including gradual blurring and transparency changes to indicate song reproduction progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional text-based or simple icon-based interfaces are used for music playback control, then device complexity is reduced, but ease of operation deteriorates due to lack of intuitive visual feedback
Solution Approach 1:
The patent applies color changes by displaying different colored graphic objects (e.g., album artwork) corresponding to different songs in the playlist. The currently reproduced song is indicated through distinct visual properties such as color highlighting or animation, providing intuitive visual feedback about playback status without requiring complex text-based interfaces or additional controls.
Solution Approach 2:
The patent transitions from traditional one-dimensional linear playlist displays to a two-dimensional graphical interface where album artwork is arranged in a grid or list format. This dimensional change allows users to visually scan and select songs more efficiently, with the currently playing song highlighted through visual cues such as borders, color changes, or position indicators.
2Loss of information
If detailed text information is displayed for each song in the playlist, then loss of information is reduced, but ease of operation deteriorates due to cluttered interface
Solution Approach 1:
The patent segments song information into distinct visual elements: graphic objects (album artwork) serve as primary identifiers, while song titles, artist names, and other metadata are displayed as separate text elements. This segmentation allows users to quickly scan visual identifiers and only read detailed information for songs of interest, reducing cognitive load while preserving complete information availability.
Solution Approach 2:
The patent uses graphic objects (album artwork images) as visual copies or representations of songs in the playlist. These graphical representations provide immediate visual recognition and aesthetic appeal, replacing the need for users to read through text-based song information for every item in the playlist, thus easing navigation while maintaining information accessibility.
3Loss of information
If static graphical objects are used to represent songs, then device complexity is reduced, but loss of information deteriorates regarding playback progress
Solution Approach 1:
The patent implements dynamic visual effects where graphic objects change appearance based on playback progress. The currently reproduced song's graphic object undergoes transformations such as gradual blurring, transparency changes, or animation sequences that visually indicate the song is playing and its progress. These dynamic effects provide intuitive feedback without requiring complex data structures or additional display elements.
Solution Approach 2:
The patent uses color and transparency changes as visual indicators of playback status. The graphic object of the currently playing song changes its visual properties (e.g., becomes semi-transparent, changes hue, or applies a blur effect) to distinguish it from other songs in the playlist. This provides clear visual feedback about which song is reproducing and its progress, using simple color manipulation rather than complex dynamic graphics.

AI summary
An electronic apparatus including an audio output unit configured to output audio information on a song being reproduced; a display unit; and a controller configured to arrange graphic objects linked to songs on one region of the display unit, respectively, that are included in a playlist, and display information on the reproduced song using a corresponding graphic object of the reproduced song among the graphic objects.
