In-Vehicle Natural Interaction Based on Electromyography

In this paper, we describe a natural interface based on microgestures performed on a steering wheel and recognized through the driver’s electrical muscular activity. This approach is based on a wearable paradigm of interaction, in which the sensors are placed on the user’s arm. The wearable system communicates with the infotainment system of our prototype through Bluetooth. We designed the gesture vocabulary in order to facilitate the driver interaction with the infotainment system while holding the steering wheel with both hands. We tested our approach with eight users showing the possibility to recognize four microgestures with an average accuracy of 94.55%.
