Example without GUI

This is an example for running SightLab without the GUI. For additional atributes and methods see this page. Find this under ExampleScripts- SampleCode- SightLabVR_NonGUI

Note: Make sure to schedule the experiment function after you’ve initialized all the other objects in the scene

Simple example with instructions and rating:

import sightlab_utils.sightlab as sl

from sightlab_utils.settings import *

# Setup SightLab without GUI

sightlab = sl.SightLab(gui=False)

# Setup the virtual environment

env = vizfx.addChild('sightlab_resources/environments/dojo2.osgb')

sightlab.setEnvironment(env)

# Add food item objects

item1 = env.getChild('basketball')  # Adjust the model name as needed

item2 = env.getChild('volleyball')

sightlab.addSceneObject('basketball', item1, gaze=True, grab=False)

sightlab.addSceneObject('volleyball', item2, gaze=True, grab=False)

# Number of trials (adjust as needed)

sightlab.setTrialCount(5)  # For example, 5 trials

def sightLabExperiment():

for i in range(sightlab.getTrialCount()):

# Display instructions at the start of each trial

if i == 0:

# Wait for an event to start the experiment only on the first trial

yield viztask.waitEvent(EXPERIMENT_START)

# Start trial (optionally add trial length, conditions, etc.)

yield sightlab.startTrial(startExperimentText = "Look at the two items and rate which one you like by using the rating scale at the end of each trial. Press trigger to begin")

# Run the trial for the specified amount of time

yield viztask.waitTime(4)

# Show rating scale and wait for participant input

yield sightlab.showRatings('Rate your preference', ratingScale=["1", "2", "3", "4", "5"], pauseTimer=True)

# End the trial

yield sightlab.endTrial(endExperimentText="Thank you for participating")

yield viztask.waitTime(2)  # Optional cooldown time between trials

viztask.schedule(sightlab.runExperiment)

viztask.schedule(sightLabExperiment)

viz.callback(viz.getEventID('ResetPosition'), sightlab.resetViewPoint)
