This multifunctional, holographic head-up display combines hands-free telephoning for mobile devices with an intelligent navigation device and extended safety functions such as lane monitoring, distance warning and facial recognition. Equipped with a transparent LCD screen, the holographic display of the Carrobot C2 projects virtual images about 2.5 metres beyond the windscreen. A very bright, thin film transistor, which adjusts automatically to its ambient light, serves as the imaging source.
