[About this application]
Without using any devices (e.g., Smart Watch, etc.), your heart(pulse) information (pulse beat, stress level, pulse rate variability) can be extracted from your pupil movement.
Your personal information will be securely protected. Only the size of your pupil will be measured to extract heart information. Therefore, no image or video will be stored.

- Measure your Pulse Rate using your smartphone.
- Measure your stress using your smartphone.
- Measure Pulse Rate Variability (PRV) using your smartphone.

※ What is Pulse Rate Variability (PRV)?
The inter-beat fluctuations in heart rate are generally known to reflect the interaction of sympathetic and parasympathetic nerves that adjust the cardiovascular function.
Heart rate is the result of the interaction between the parasympathetic nerve that slows the heart rate and the sympathetic nerve that speeds up the heart rate, which varies from time to time depending on the internal and external environment.
Healthy people are ready to respond sensitively to changes in their environment, be resilient, and respond quickly if necessary.
Heart rate can be checked by time series analysis(BPM, SDNN, RMSSD, etc.) and frequency series analysis (LF(%), HF(%), etc.).
Heart rate and pulse rate show a slight delay, but domestic and international studies have reported little difference between heart rate and pulse rate.
