Mercedes-Benz is presenting another particularly user-friendly innovation in the F 800 Style in the form of a new human-machine interface (HMI) equipped with a cam touchpad. The feature is a well-conceived system expansion for COMAND. The HMI unit here consists of a touchpad on the centre console and a camera that records video images of the user’s hand as it works the pad. The live image of the hand is presented in transparent form in the central display above the console. The key advantage of this solution is that icons that would be covered by the hand with conventional cell phones, for example, remain visible.

Users see their hands glide across the touchscreen as a “transparent” contour, allowing them to operate the functions of the current menu by applying a slight pressure. The touchpad can be operated with several fingers at the same time, and operating it feels similar to touching the keys of a notebook computer. Because the user interface is depressed by a few millimetres when touched, the activities carried out with the fingers are physically confirmed by the sense of touch.
