Reference Display Device for Karaoke Note Connection Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Karaoke systems and display devices fail to intuitively represent the connection and breathing timing between notes, making it difficult for users to recognize and perform smoothly.
Innovation Solution
A reference display device with an image generator that connects notes in a guide image and disconnects them at breathing timings, along with additional visual cues for geminate consonants, volume, and singing techniques, to enhance user recognition and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If notes are displayed as separate linear images in a piano roll, then start timing and pause timing can be recognized, but connection and breathing timing between notes cannot be intuitively recognized
Solution Approach 1:
The display is segmented into two distinct modes: a piano roll view for precise timing identification and a guide image view for intuitive connection recognition. This segmentation allows users to switch between detailed timing information and overall performance guidance without confusion
Solution Approach 2:
A guide image is introduced as an intermediary visual element that overlays or accompanies the piano roll display. This guide image uses connected lines to represent note connections and breathing timings, bridging the gap between precise timing data and intuitive performance understanding
2Measurement precision
If detailed timing information is provided for each note, then precise timing can be identified, but the overall connection and breathing structure becomes less visible
Solution Approach 1:
The piano roll display and guide image are merged into a unified interface where both detailed timing information and overall connection structure are simultaneously visible. The guide image overlays key performance structures onto the detailed note timing display, ensuring neither level of information is lost
3Device complexity
If a simple piano roll display is used, then the interface remains simple, but additional performance guidance such as breathing and connection cues are lost
Solution Approach 1:
Performance guidance information is added in a visual dimension rather than increasing textual or numerical data. The guide image uses spatial relationships, line connections, and visual markers to convey breathing and connection cues without adding complex controls or interfaces

AI summary
Provided are a display device and a program which allow a user to intuitively recognize a connection and a breathing timing between respective notes. A CPU (11) generates a guide image, based on information about a sound-producing timing and a sound length of each note, which are included in a guide melody track. The CPU (11) smoothly connects respective notes. Thereafter, the CPU (11) disconnects the notes at the breathing timing indicated in a breath position track.
