C4DT’s lead developer, Linus Gasser, participated in last weekend’s LauzHack Against COVID-19, which is a 72h online hackathon dedicated to fighting the coronavirus crisis, to develop an app called Indie-Pocket. It uses various sensor data from the smartphone and a supervised classification technique to decipher in which pocket/body location the smartphone is located at that time. This inference will help measure distance between people’s phones via Bluetooth as part of EPFL’s privacy-preserving proximity tracking work, an EPFL project referred to as PEPP-PT.
