public class FittsTaskTwoTrace
extends java.lang.Object

FittsTaskTwoTrace - an application to plot the trace data in the sd3 files created by FittsTaskTwo.

The sd3 data file processed by this application must be in a specific format. Each trace is encoded in three consecutive lines: (i) the timestamps, (ii) the x samples, and (iii) the y samples. The trace data are preceded with the following trial identifier data:

     block - block number
     A - target amplitude (distance in pixels to the target)
     W - target width (diameter of target circle in pixels)
     trial - trial number within block
     from_x - x coordinate of beginning of trial
     from_y - y coordinate of beginning of trial
     to_x - centre x coordinate of target circle
     to_y - centre y coordinate of target circle
