Pitch frequencies to be respectively Fa, Fb, and a key to the angular displacement of b key be Lab, when glide from
When b point starts the h point sliding between ab two key, its angular displacement is Lbh, then h point frequency
The computing formula of rate Fh is:
Fh=Fb+Lbh* (Fb-Fa)/Lab
As shown in Figure 7, it is generally the case that Fa, Fb and Lab are known (by micro-sense palm
Upper musical instrument sets), only Lbh gradually changes with playing procedure, and passes through data acquisition in real time
Collect and obtain.During performance, when pressing the finger upward sliding of b key, often move one small
Step pitch, all measured by gyro sensor, and obtained real-time displacement by microprocessor samples
Lbh, then it is calculated corresponding frequency Fh by formula (4), simply it is noted that angular displacement is moved
Direction, if by b point upward sliding, be then negative after displacement acquisition, if downward by b point
Slide, then the displacement gathered be positive number, i.e. upward sliding be negative, slide downward is just, and
Being determined by sampling, the pitch frequencies that thus have followed button is the highest
