Announcement!!

We are excited to announce that PsychoPy will be hosting a 3-day in-person code-sprint at the University of Nottingham from 15-17 April 2024. The code sprint will be an opportunity for us to get together in person and improve PsychoPy/JS. Anyone who would like to attend will need to fill out the online application by 31 January 2024. Those selected will be notified by the end of February.

PsychoPy is an open-source package for creating experiments in behavioral science. It aims to provide a single package that is:

• precise enough for psychophysics
• easy enough for teaching
• flexible enough for everything else
• able to run experiments in a local Python script or online in JavaScript

To meet these goals PsychoPy provides a choice of interface - you can use a simple graphical user interface called Builder, or write your experiments in Python code. The entire application and library are written in Python and is platform independent.

There is a range of documentation at:

• PsychoPy Homepage
• Youtube
• The textbook, Building Experiments in PsychoPy
• The discourse user forum

psychopy-eyetracker-gazepoint's Issues

Gazepoint plugin not working

This does not work. I have been trying to make it work with the current distribution of psychopy (2023.2) and nothing makes sense been trying to fix it without success, and not being able to narrow it down.

My basic code:

`from psychopy import core, visual
from psychopy.iohub import launchHubServer

# Configure the eyetracker devicepip
iohub_config = {
    "eyetracker.hw.gazepoint.gp3.EyeTracker": {
        "name": "tracker",
        "enable": True,
        "save_events": True,
        "stream_events": True,
        "event_buffer_length": 1024,
        "monitor_event_types": ['BinocularEyeSampleEvent', 'FixationStartEvent', 'FixationEndEvent'],
        "calibration": {
            "target_duration": 1.25,
            "target_delay": 0.5
        },
        "model_name": "GP3",
        "manufacturer_name": "GazePoint"
    }
}

# Start the ioHub server with the configuration
io = launchHubServer(**iohub_config)
tracker = io.devices.tracker

# Setup a window for calibration
win = visual.Window(fullscr=True)

# Start the calibration process
tracker.runSetupProcedure(win)

# Main experiment code goes here

# Cleanup
win.close()
io.quit()
`

This is the error:

*** iohub warning: Display / Monitor unit type has not been set.
