Machine Learning for Touch Localization on an Ultrasonic Lamb Wave Touchscreen
Sensors, 2022 Classification and regression employing a simple Deep Neural Network (DNN) are investigated to perform touch localization on a tactile surface using ultrasonic guided waves. A robotic finger first simulates the touch action and captures the data to train a model. The model is then validated with data from experiments conducted with human fingers.
