Abstract:From a very young age, we are told to brush our teeth for 2 minutes, 2 times a day. On the other hand, there is little guidance on how to spend those 2 minutes. In this work, we created an end-to-end ML solution that tracks the toothbrush inside the mouth to generate signals that can be used for user guidance. Our NN based solution takes 3D Accelerometer and 3D Gyroscope data as input and predicts probabilities for 12 (sub) segments at each timestamp. The solution was integrated into the Sonicare app (iOS + Android) and released as part of the Sonicare Prestige 9900 launch. The delivery was highlighted as a Grand Cru with 100M+ Euros business impact. Our contributions include: 1) Supervising a large digital clinical trial with 1500 participants. 2)Data Engineering from Video timelines to IMU with a novel approach to synchronize IMU and Video timestamps, 4)Training and evaluation of NNs, achieving 85% accuracy at 12 segment(s) 5)a continuous integration and delivery pipeline.
