Emotion

What is emotion? Current psychological science suggests that the experience of emotion is constructed out of at least three key “ingredients”: a) Internal sensations from our body; b) Information we collect from the external world (e.g. Where am I? What is happening around me? What is that smell?);

Biology

How do our bodies process emotions? A look at the Sympathetic and Parasympathetic nerve systems provides insight. Imagine that you’re taking a stroll in the park when suddenly, an angry bear appears. Your heart starts to beat faster, while blood pressure may rise. The palms and feet start to sweat and your muscles tense.

Computer Science

So, how does it work? 
By leveraging four embedded sensors via the wristband, Feel collects these indicators and analyses them using cutting-edge methods of computer science. Heart Rate Variability (HRV) is measured through a photoplethysmogram (PPG) sensor that captures slight differences in heart rate as one lives through emotional experiences.

Processing & Regulating your Emotions

Feel helps you become more aware of your emotions so you can gain a deeper understanding of their internal and external triggers. Based on information collected by the Feel wristband and your input on the Feel app, you’ll receive tailored guidance on how to better regulate and optimize your emotional experience.
