TY - Type of reference TI - Automatic classification of emotions using motion sensors and keystroke dynamics on smartphones AU - Nicolas Simonazzi AU - Jean-Marc Salotti AU - Caroline Dubois AU - Philippe Le Goff AB - We present the results of a study on a binary classification of emotions, based on data collected through motion sensors and keystrokes of a smartphone and a connected bracelet. To this end, we developed a mobile application to induce emotions through videos and record user interactions. A specific digital self-assessment system was developed based on the Geneva Emotion Wheel to help participants express their emotions. The sensor recordings were labelled according to participants’ statements and video conditions. A method is thus proposed to process the collected temporal data and automatically classify the valence of the declared emotions using machine learning techniques. We tested a general valence classification using all emotions from all individuals and a personalized classification using a subset of emotions from a single individual. The most promising result was obtained with a personalized model, for which we were able to obtain, on average across all participants, two-thirds of correct valence classification, using fused data from different modalities.
