Graphical user interface(GUI), a synthesiser and a computer system including a GUI
View Patent ↗The present invention relates to a graphical user interface (GUI), a synthesizer and a computer system including such a graphical user interface. In the prior art, input signals may be modified using a variety of controls including rotatable knobs or levers or switches or effected via software controls. Hitherto, the value of each signal has been represented in a dedicated manner even when signals are being combined and this adds to the complexity for a user. The present invention thus relates to a graphical user interface for displaying three or more input signals; comprising a geometric display having the number of dimensions equal to one less than the number of signals whereby each signal represents an apex of the geometric display and a cursor is disposed within the geometric display and represents the combination of the signals.
1. A computer system having a display for displaying a graphical user interface for displaying three or more input signals, an input device for enabling a user to interact with the displayed graphical user interface, the graphical user interface comprising a geometric display having the number of dimensions equal to one less than the number of signals whereby each signal represents an apex of the geometric display and a cursor is disposed within the geometric display and represents the combination of the signals.
2. A graphical user interface as claimed in claim 1 , in which there are three signals and the geometric display comprises an isosceles triangle in a two dimensions.
3. A graphical user interface as claimed in claim 1 , in which there four signals and the geometric display comprises a triangular pyramid.
4. A graphical user interface as claimed in claim 1 , further comprising a primary control for each input signal.
5. A graphical user interface as claimed in claim 4 , in which said primary control controls the frequency of the input signal.
6. A graphical user interface as claimed in claim 4 , further comprising a secondary control for each input signal.
7. A graphical user interface as claimed in claim 6 , in which said secondary control controls the amplitude of the input signal.
8. A synthesiser including a graphical user interface as claimed in claim 1 .
9. A synthesiser as claimed in claim 8 , in which said input signals are each generated using an oscillator.
10. A synthesiser as claimed in claim 8 , further comprising a memory for recording the input signals varying with time.
11. A computer system including a graphical user interface as claimed in claim 1 .
