Audio Reproducing Apparatus Visual Data Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in efficiently finding specific audio data among a large collection, as conventional methods rely solely on textual information, making it challenging to identify desired songs or data without specific titles or phrases.
Innovation Solution
An audio reproducing apparatus and method that displays images associated with audio data in a fixed array, allowing users to select and reproduce data based on position, with additional features like cursor trajectory display for reproduction history, enabling efficient data selection and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users search through audio data using only textual information (titles, names), then the system remains simple, but the efficiency of finding desired data decreases as the number of stored audio data increases
Solution Approach 1:
The patent transforms the one-dimensional textual search into a two-dimensional visual search space by displaying thumbnails of audio data in a grid array. Users can navigate this spatial arrangement using cursor control, enabling them to locate desired audio files by visual scanning and positional memory rather than linear text scanning, thereby significantly improving search efficiency for large datasets.
2Ease of operation
If the system displays images associated with audio data in a fixed array, then users can efficiently locate data using visual cues and position memory, but the system requires additional components for image display and cursor control
Solution Approach 1:
The patent introduces a cursor as an intermediary element that mediates between the user's input device and the array of audio data thumbnails. The cursor visually indicates the current selection position and enables precise navigation through the data array, making the interaction more intuitive and accurate while managing the complexity of the additional display components.
3Productivity
If the system allows ambiguous selections for sound zapping, then users can quickly browse through audio data, but the precision of data selection decreases
Solution Approach 1:
The patent implements dynamic selection behavior where the system responds differently based on the user's interaction pattern. For rapid browsing, the system allows ambiguous selections that enable quick navigation through multiple items. When the user pauses or makes a deliberate selection, the system transitions to precise selection mode, ensuring accurate data retrieval. This dynamic adaptation resolves the contradiction between browsing speed and selection precision.

AI summary
An image display field, a whole map display field, a cursor are displayed on the music data selection screen. In the image display field is displayed an array of images which belong to one partition that can be displayed at a time and which are included in an array of images which represent whole audio data and is defined fixedly in advance. In the whole map display field is displayed a whole map indicating a display-area guide which shows where a partition being displayed now is located in the whole array and indicating a trajectory line which represents the trajectory of the cursor in the past. A plurality of pieces of music data represented by an image, which the cursor indicates, and images located around the image are reproduced concurrently.
