Track hand/object position using 2 web cams. One from top and one from side.
Ask user to move to a target.
Create a reward either as they begin to move towards the target, or when they get to the target (sound, graphic).
The software should store x,y,z position during each trial as well as when the reward was provided.
The data should be stored in a Matlab file and a backed up comma deliminated text file.
