We have developed a mobile phone app to connect with the E4 wristband. It presents the biosignals changes and detected emotion. The wristband connects to a Mobile phone, iPhone or Android through Bluetooth. The mobile phone reads the sensor data from the wristband and sends it to a web server via the internet. The web server runs the machine learning model that makes a prediction of the users’ emotional state and returns it to the mobile phone to be displayed on the app. Users can view their emotional history data on the app for a particular date. The app also allows for active learning for continuous improvement of the machine learning model. The learning mode can be enabled or disabled by the user.
When learning mode is enabled, the app will run in the background and occasionally prompt the user to confirm or correct an emotional prediction. Corrections are added to the dataset and the model is re-learned with the new data, improving its ability to predict emotions based on real data.
