The equation solved is f(x, y, z, u) = x + y * y + z * z * z + u * u * u * u = o.

I was administered a VVF Test on Wednesday, January 15, at Dr. Brent Brown and Associates Inc office in LaGrange, Georgia. The test consists of using a headset that has an orange circle in the center of the display. The examinee has a trigger device to click each time a white flash occurs. I decided to write a C/C++ Win32 application to simulate the VVF Test. The following two pictures are from a simulated test of one minute in duration. The white flashes are separated by 1000 millisecond (1 second) and their durations are also 1000 milliseconds (1 second).
