Fortunately, Carnevali’s idea paralleled the rise of the computer-electronics industry, and faster processors, bigger and less-expensive memory, and enhanced graphics spurred marine-electronics companies to innovate. Over time, simple chart plotters evolved into a brain for yachts, a trend that quickened with the introduction of GPS and networked-data backbones. Still, user interfaces (UI) were problematic, because multifunction display (MFD) operating systems (OS) weren’t intuitive. Enter the iPhone, with its touch-screen UI and philosophy that software should be user-friendly. Almost instantaneously, users became touch screen savvy, and marine-electronics manufacturers started leveraging this technology in multifunction displays.
