Empatica E4 realtime

E4 realtime is a research application that allows you to visualize live physiological signal data from the Empatica E4 wristband. E4 realtime stores streamed data and automatically backs up data to your Empatica Connect account after the streaming session is completed.

In order to use this app, you need a compatible Empatica E4 wristband research device. The E4 realtime app does not work with the Embrace watch. If you want to know more, please contact Empatica at sales@empatica.com or check our website www.empatica.com/research/e4/.

The E4 realtime app allows you to visualize the following physiological parameters from the E4's onboard sensors:

• Blood-volume Pulse (BVP) waveform and current heat-rate
• Electrodermal Activity (EDA) waveform and current skin conductance level
• Accelerometer state
• Peripheral temperature
