Musical Instrument Audio Signal Processing for Cursor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Musicians face the challenge of needing to remove their hands from musical instruments to interact with computer interfaces, such as keyboards or mice, which disrupts their playing experience.
Innovation Solution
A system that uses a musical instrument, like a guitar, to generate audio signals that control a cursor or indicator on a graphical user interface, allowing musicians to manipulate digital elements without physically interacting with a separate input device by processing specific musical phrases and pitch changes to direct cursor movements and selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If musicians use traditional computer input devices (keyboard or mouse) to control graphical user interface, then the computer interface can be manipulated, but the musicians must remove their hands from the musical instrument which disrupts the playing experience
Solution Approach 1:
The musical instrument is equipped with both traditional musical functions and computer interface control functions. The processor detects musical phrases, pitch changes, and playing techniques to generate control signals that manipulate the graphical user interface, allowing the instrument to serve dual purposes without requiring separate input devices
Solution Approach 2:
The patent combines the musical instrument with computer input control capabilities by integrating a processor that translates musical performance into interface control commands. This merging eliminates the need for musicians to switch between instruments and input devices, as both functions are unified in a single system
2Adaptability or versatility
If the electrical device processes musical audio signals to control cursor movement, then hand position on the instrument is maintained, but the system complexity increases
Solution Approach 1:
The patent replaces mechanical input devices (mouse, keyboard) with an acoustic signal processing system. The processor analyzes musical audio signals, detects phrases and pitch changes, and converts these acoustic patterns into digital control commands, substituting physical manipulation with acoustic-based control
Solution Approach 2:
The processor acts as an intermediary that translates musical performance into interface control signals. It receives audio signals from the instrument, processes them to detect musical phrases and characteristics, and generates corresponding control signals for the graphical user interface, bridging the gap between musical expression and digital control
Data Source
AI summary
A musical instrument system is described to operate as a human to machine input device. The musical instrument outputs an audio signal that is processed to control the movement of an indicator in a computer.
