UNMASKED is an Arduino-powered biometric experiment that studies involuntary emotional responses to visual stimuli. Participants watch a curated sequence of videos while physical sensors record what their body cannot hide.
a Heart-rate pulse sensor is connected to the participant before the experiment begins.
A difficulty level is selected. The video sequence plays automatically on screen, the participant cannot control playback.
The Arduino reads sensor data in real time throughout the sequence, logging in changes and monitoring face movements.
The participant wins by showing no reaction through spike pulse sensor, even the smallest spike captured by the sensor leads to loss.
The microcontroller at the core. Reads analog sensor values and transmits data in real time.
Tracks heart rate via optical sensing. Spikes reveal moments of fear, surprise, or excitement.
A small screen on the Arduino rig shows live readings to the experimenter during the session.
This is a student research project. All participants consent before taking part. No personal data is stored. Video stimuli are selected responsibly and are not intended to cause lasting distress.
