Mercedes-Benz’s latest autonomous concept car, the Vision AVTR, boasts a ‘brain-computer interface’ that allows passengers to control various features with their thoughts. To operate, users focus on lights on the digital dashboard and the car’s artificial intelligence recognizes their choice and begins a preset function. This could include changing a radio station, opening a window, answering a phone call, or, eventually, sending the car on a predetermined route. ‘The BCI device measures the neuronal activity at the cortex in real-time. It analyzes the measured brainwaves and recognizes on which light points the user directs [their] focus and full attention,’ Mercedes said in a release. Daily Mail
