Interpolate from two sensor values (gyrox,gyroy) into mouse (x,y) space.

See: Youtube Demo

Background

Allows arbitrary positions to be set by a user with accessibility issues, whereby they choose the positions they desire for Up, Down, Left, Right, and Center (rest).

The interpolation then is effectively a mapping or piecewise transform from those positions into mouse movement values.

Caveats

• Currently the calls to the on-screen preview use Linux. The interpolation code is not actually dependent on this, but for now main.c utilizes it so this probably won't build in, say, Windows. I make calls to ioctl(), tcgetattr(), etc. Stripping out use of termstuff.c and .h would get rid of that dependency.
• Please ignore that main.c is not .cpp
• The classes will end up being moved out of main.c
• This code does not deal with the sensors, which is a different project (an Arduino .ino project). This was just to develop the mapping/interpolation library.

Running

• Type make. It should just run (in Linux)

Using in your own project

• Copy radterpolate.cpp and .h to your project folder, for now.
• See main.cpp for example use
