visigoth.eyetracker.EyeTracker

class visigoth.eyetracker.EyeTracker(exp, edf_stem='eyedat')

Interface to EyeLink eyetracker.

The main reason for the additional layer of complexity is to allow simple eyetracker simulation with the mouse in a way that is transparent to the experiment code. This object also has some helpful interface functions, allows for dynamic offset values, and it maintains a log of samples.

__init__(exp, edf_stem='eyedat')

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(exp[, edf_stem])	Initialize self.
check_eye_open([new_sample, log])	Return True if we get a valid sample of the eye position.
check_fixation([pos, radius, new_sample, log])	Return True if eye is in the fixation window.
close_connection()	Close down the connection to Eyelink and save the eye data.
last_valid_sample([apply_offsets])	Return the timestamp and position of the last valid gaze sample.
read_gaze([log, apply_offsets])	Return the position of gaze in degrees, subject to offsets.
run_calibration()	Execute the eyetracker setup (principally calibration) procedure.
send_message(msg)	Send a message to the eyetracker, or no-op in simulation mode.
setup_eyelink()	Connect to the EyeLink box at given host address and run setup.
shutdown()	Handle all of the things that need to happen when ending a run.
start_run()	Turn on recording mode and sync with the eyelink log.
update_params()	Update params by reading data from client.
write_log_data()	Save the low temporal resolution eye tracking data.
