Sampling Device Auto-Playback for Intuitive Novice Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sampling keyboards are difficult for novice users to understand and utilize, as they lack intuitive guidance on how to operate the sampling feature, leading to underutilization of this feature.
Innovation Solution
A sampling device with a sound wave receiver and processor that converts external sound wave data into digitized tone data, allowing for playback of rhythm patterns or musical phrases, and includes a user-friendly interface with message displays and auto-start sampling to facilitate intuitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sampling keyboards provide sampling features, then the feature can be used for professional or expert users, but novice users cannot intuitively understand how to operate the feature
Solution Approach 1:
The patent applies preliminary action by automatically playing back sampled data as a tone immediately after the sampling process completes. This automatic playback serves as an intuitive feedback mechanism that guides novice users through the sampling feature without requiring additional manual instructions, thereby resolving the contradiction between ease of operation and information loss.
Solution Approach 2:
The patent implements feedback by providing automatic playback of the sampled data as a tone to the user. This feedback loop allows novice users to hear the result of their sampling action immediately, reinforcing their understanding of how the sampling feature works without requiring complex user manuals or additional guidance.
2Reliability
If sampling keyboards include detailed guidance systems, then expert users can operate the feature effectively, but the device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the sampling keyboard to automatically play back sampled data without requiring additional user intervention or complex control mechanisms. The system serves itself by providing intuitive feedback through automatic playback, eliminating the need for separate guidance systems or complex user interfaces while maintaining reliable operation of the sampling feature.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables novice users to intuitively understand and effectively use the sampling feature by automatically playing back sampled data as a tone, making the feature more accessible and appealing, especially for children and non-experts.
Implementation Method 1
The sampling keyboard performs A/D (analog-digital) conversion to the external sound wave data that is received and then stores the converted data in an internal memory
Implementation Method 2
playing back the play data that have been read out using the digitized tone data as a tone
Data Source
AI summary
The present invention receives sound wave data from a sound inputted into a microphone and samples the sound wave data received using a CPU to obtain sampled data as a digitized tone data, which is then stored in a sampling memory. The CPU performs auto-play of a sound using the digitized tone data sampled by the sampling and stored in the sampling memory. Thus, a result of the sampling is automatically provided to the user after the sampling takes place and the user can intuitively understand what can be done through sampling.
