Infotainment, HMI (human-machine interface), and connectivity encompasses functions that allow the driver and passengers to interact with the vehicle. This delivers the convenience, information, and entertainment in a safe and seamless fashion. These are among the most readily-visible and highly-used functions in the vehicle. These functions provide the greatest opportunity for unique branding and differentiation. This includes traditional radio tuners on the low end all the way to complex infotainment systems controlled through large touch panel displays. Although the range of functions is quite broad, they share many common design challenges, among them. We test the software to ensure the complex technical functions are perfectly interlinked to one another. The applications interact with one another and are easy for the driver to operate.
