Here, in order to prevent the driver's vision from the "main visual perception zone" too much toward the center console, Audi will be integrated into the dashboard navigation. However, based on the previous list of driver needs, the driver's perceived need for vehicle information is higher than for road navigation. Therefore, on this screen, even with navigation, speed and speed still cover the front of the map, with a higher display priority. For the driver, this design appears to be casual, but they are all considered a careful driving logic and design. In summary, the car is not installed on the wheels of the smart phone, and then those suitable for mobile phone use UI design, are not necessarily suitable for car driving environment. The development of the onboard VR product must be based on the driver's perception of the actual road condition and not allow the driver to indulge in the virtual world built up by the VR product. In this sense, AR is more suitable for automotive environment technology, it can not affect the driver's perception of the external world under the premise of information collection and enhancements. But it must be noted that, whether AR or VR, can not be too much distraction driver's attention, must give way to the display of vehicle information, and then their own operating environment in the car to keep a low profile, you can always be easily shut down. At the same time, in the human-computer interaction design, the use of more traditional knob-type knob control, the tactile feedback, compared to the seemingly tall and actually not practical touch screen control is more in line with the car center console Engineering design principles.
