The afternoon will be focused time allowing researchers to start creating their own eye tracking experiment- with the PsychoPy and Tobii team on hand to assist! Attendees can either bring their own Tobii or use Tobii equipment available in the session. The workshop will be divided into two goals the morning session will be tailored towards a general introduction to PsychoPy, making experiments and getting started with inbuilt eye tracking functionality. This workshop is designed to equip researchers with the skills needed to make an eye tracking experiment in PsychoPy using Tobii eye tracking equipment. The latter file is a small script which automatically checks and downloads required packages.This event is now sold out please register interest hereĬome and learn PsychoPy AND make your Tobii eye tracking experiment with us! Open a new R script file with ( then save it the same location that and getpk.R files are. To process the HDF5 output files make sure that you follow the PsychoPy method described above, then: The output file may be quite big as it collects all trials for each participant if your tracker is sampling at 300Hz that means that you can expect around 300 lines per second of tracking. Having RStudio installed would make this process much less painful.Īll the R function needs is the location of hdf5 files it will get all the trials epoched and save output into a csv file, optionally it will save all required data into your R environment. You should know how to open an R script file and execute code. To process the data you need to have R installed on your machine, and have some very basic knowledge of R. Thanks to the codes we were sending to the IOHUB on each trial, we are able to epoch the eye tracking data based on related time vales. The etDemo.psyexp is a simple experiment in which subjects are asked to look at the dots, it has been designed with PsychoPy 1.82.01 (Mac). If instead you see the events.hdf5 file in the experiment folder then this means that either you have not included the End Experiment code or the experiment was terminated before it run was meant to finish. Upon completion of the experiment you should see a new hdf5 file being added to the root directory this will be named hdf5_et_X_YYYY.hdf5 where X is your participant's id and YYYY is a date and time. sendMessageEvent( text = "tEnd %i" %( trials. We also need some code to be executed in the End Experiment part: An example Tobii TX300 tobii_std.yaml file is included in this repo and should be in the same directory as the PsychoPy file. Please note that the above code uses a hardware configuration file tobii_std.yaml which is specific to your tobii device. Import sys print "!! Error starting ioHub: ", e, " Exiting." sys. sendMessageEvent( text = "SSID: %s" %( expInfo)) sendMessageEvent( text = "DATE: %s" %( expInfo)) sendMessageEvent( text = "%s" %( expInfo)) # Send some info about the experiment to the IOHUB io. ![]() # Create an ioHubConnection instance, which starts the ioHubProcess, and informs it of the requested devices and their configurations. Here we use the psychopy getDateStr() function for session code generation session_info = io_config. # Add / Update the session code to be unique. io_config = load( file( 'tobii_std.yaml', 'r'), Loader = Loader) data import getDateStr # Load the specified iohub configuration file converting it to a python dict. ![]() util import NumPyRingBuffer from psychopy. iohub import EventConstants, ioHubConnection, load, Loader from psychopy. ![]()
