keywords:
logfile:
desc: |
A logfile name (string value); path may be included in the
file name for SMI and for Tobii; SMI will create a `.idf`

DO NOT USE THIS: use `data_file` instead, see below for
explanation.
type: [unicode, str]
eventdetection:
desc: |
A string specifying the type of event detection, either
'native' for system default functions (not always
available!), of 'pygaze' for Dalmaijer et al. (2013)

for SMI and Tobii).

desc: |
Calibrates the eye tracking system. The actual behavior of this
function depends on the type of eye tracker and is described below.
__EyeLink:__
This function will activate the camera-setup screen, which allows
you to adjust the camera, and peform a calibration/ validation
procedure. Pressing 'q' will exit the setup routine. Pressing
'escape' will first trigger a confirmation dialog and then, upon
confirmation, raises an Exception.
__EyeTribe:__
Activates a simple calibration routine.
returns:
desc: |
Returns True if calibration succeeded, or False if not; in
addition a calibration log is added to the log file and some
properties are updated (i.e. the thresholds for detection
algorithms).
