This is an example of an effective technique for using the continuous data from the sensors on the Snyderphonics Manta.
While it's possible to get useful data from the sensors when conceiving of them as a sort of psuedo-pressure sensor, they are actually sensing the total surface area covered by the finger. The technique demonstrated here is what we have found to be the most effective way to achieve a nice range of control over the sensors.
Placing your finger on the sensor with the flat part of the fingertip covering as much surface area as possible, and then rolling the finger up until only the tip is touching the top of the hexagon will produce a smooth decrease in sensor values.
Conversely, starting with the finger pointing straight down, and the fingernail just above the top of the sensor, then rolling the finger down to cover more surface area, will produce a smooth increase in sensor values.
