IBM has announced a collaboration with the BMW group to develop new potential interfaces for its Watson AI product into vehicles. The agreement will see the car manufacturer relocating a group of its researchers and engineers to the IBM headquarters for Watson IoT in Munich, with the scope of exploring new'intelligent assistant' functions for the BMW range. Four BMW i8 hybrid sports cars will also take up residence at the Munich centre, as lab fodder prototype Watson-based experiments to run on IBM's Bluemix cloud platform. According to today's release, the objective is the development of new'conversational interfaces' between cars and drivers. The i8's manual will be integrated into Watson's database for the purpose of the experiments, allowing drivers to ask natural language questions and hope to receive a better response than the commonly-lamented AI offer to'look it up on the web for you'.
