Dynamic Touch Control for Electronic Musical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic musical instruments have complex control panels due to numerous functions, making it difficult for users to intuitively set and control various settings, and existing solutions either simplify the panel by frequent function changes or complicate it with more controls, neither of which is optimal.
Innovation Solution
A system comprising an information processing terminal that communicates with an electronic device, using positional and attitude detection to dynamically change settings on a touch-sensitive display, allowing users to control the device by moving the terminal across a detection area on the instrument, thereby simplifying the control panel configuration and enabling intuitive settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of controls is increased to provide all functions, then the number of times of changing functions assigned to controls is reduced, but the control panel configuration becomes complicated
Solution Approach 1:
The control panel uses a single control unit that can be dynamically assigned to different functions based on the detected position of the information processing terminal. This multi-functional approach allows one control to serve multiple purposes, eliminating the need for numerous dedicated controls while maintaining full functionality.
Solution Approach 2:
The control panel dynamically changes the function assigned to the control unit based on real-time detection of the terminal's position. This dynamic reassignment allows the same physical control to adapt to different functions, simplifying the panel structure while providing access to all electronic device functions.
2Device complexity
If the number of controls is decreased to simplify the control panel configuration, then the control panel becomes simpler, but the number of times of changing functions assigned to controls is increased
Solution Approach 1:
The system automatically and dynamically changes the function assigned to the control unit based on the terminal's position without requiring user intervention. This automated dynamic reassignment eliminates the time users would otherwise spend manually changing functions, while maintaining a simple control panel with fewer controls.
Solution Approach 2:
The control panel incorporates a detection unit that provides feedback about the terminal's position to the control unit. This feedback mechanism enables automatic function reassignment based on position, reducing the need for manual function changes and minimizing time loss.
3Ease of operation
If a screen corresponding to each control is provided to enable intuitive grasping of functions, then intuitive settings are enabled, but the control panel configuration becomes more complicated
Solution Approach 1:
A single display unit serves multiple functions by showing different setting screens corresponding to different functions assigned to the control unit. This multi-functional display approach provides intuitive visual feedback for each function without requiring separate displays for each control, maintaining simplicity while enabling intuitive operation.
