We monitor subjects' eye, head, and hand movements while they
perform a block-copying task. In this photo, I am wearing the headband
mounted ASL eyetracker which monitors eye-in-head position using an infrared
illuminator and a small video camera visible at the front of the
headband. The eye's image is reflected by the visor (which reflects IR
while passing visible light). Movements of the head and hand
are monitored by magnetic coils on the headband and hand, respectively.
The video monitor in the background shows the image captured by the 'scene
camera' mounted on the headband (visible on the near
side of the headband) The crosshair cursor on the monitor indicates
where in the scene the subject is looking (in this case, I am fixating
the area on the board where I am placing a block).
