Researchers and engineers from BMW are working at IBM's Munich headquarters for its Watson Internet of Things (IoT) technology. They'll help develop IBM's Watson cognitive system, which can learn from and pass back intelligence into the physical world, for integration into automotive products. BMW is providing the IBM site with four i8s to be used as prototypes for these new artificial intelligence systems. The systems will run on IBM's Bluemix cloud platform, which IBM said will enable Watson technology to heighten a driver's connection with their car. The technology uses machine learning to enable a car to improve its understanding of its driver, so it can cater its systems and cabin experience to suit their preferences.
