Feel is getting close to releasing a rather svelte looking wristband that recognizes five basic emotions (happy, angry, sad, stressed and satisfied). The device is equipped with four bio-sensors, Bluetooth LE and is waterproof. The bio-sensors are:
HRV – Heart Rate Variability
GSR – Galvanic Skin Response (sweat)
ST – Skin Temperature
IMU – Inertial Measurement Unit (IMU)
The HRV is being accomplished with the use of a Blood Volume Pressure (BVP) sensor. Feel includes a companion app to help track emotions on a calendar level. The goal is to determine where, when and during what activities with whom cause patterns in emotion.
