• Configuration: Import multiple images or videos, and configure the resolution to match your study requirements.

2. Audio Stimuli

• Supported Formats: MP3, WAV.
• Usage: Perfect for auditory experiments or scenarios where sound is a key element. Can be combined with images for audiovisual presentations.
• Configuration: Import sound files and optionally pair them with images to display while the audio is playing.

3. Web Stimuli

• Browser Support: Chrome, Microsoft Edge.
• Usage: Conduct web-based studies where participants interact with websites. Useful for usability testing and digital content evaluation.
• Configuration: Set up web stimuli by entering URLs, and use integrated webdrivers to capture web interactions without additional software.

4. Screen Recording

• Usage: Capture participants’ interactions with applications or websites directly from their screen. This is particularly useful for usability studies and software testing.
• Configuration: Record the stimulus presentation screen into a video and overlay eye-tracking data for detailed analysis.

5. Face Recording

• Usage: Record participants’ facial expressions using a USB camera without displaying any stimuli. Ideal for post-processing facial expression analysis.
• Configuration: Set up face recording in the study settings and use it to capture facial data during interactions.

6. Scene Recording

• Usage: Record physical scenes using external video sources such as USB cameras or frame grabbers. Suitable for studies involving physical interactions or product testing.
• Configuration: Integrate scene recordings with biometric data for a comprehensive view of participant behavior.

7. Survey Slides

• Usage: Create survey slides with various question types such as multiple choice, Likert scales, and text inputs. Combine with images and formatted text for enhanced presentation.
• Configuration: Design and integrate surveys into your study to collect self-reported data alongside biometric measurements.

8. Qualtrics Survey Integration

• Usage: Direct participants to Qualtrics surveys while measuring their biometric responses. Useful for combining survey data with physiological measurements.
• Configuration: Set up Qualtrics surveys to work seamlessly with iMotions, ensuring synchronized data collection.

9. Advanced Synchronization Options

• API and TTL Integration: Use the API to receive marker events from devices like the Cedrus StimTracker, or synchronize data with third-party devices using TTL pulses.
• Usage: Essential for studies requiring precise timing and synchronization, such as EEG/ERP studies or motion capture research.
• Configuration: Configure synchronization settings in the global settings and ensure accurate data alignment across devices.
