In the envelope long common, the automotive manufacturer BMW relies on the so called head-up display: driving information, such as navigation, speed, various warning messages and move more for the actually the view of the on-board computer is necessary, in the truest sense of the word directly in the field of view of the events, namely on the windshield.

In the sense of security developed by the BMW Head-Up Display projecting a way to driving-related information onto the windshield. In air transport, this technology is nothing new in the automotive sector since 2004, but in the context of BMW ConnectedDrive is an innovation - the wheel was not invented then, but in terms of consumer developed.Head-up displays: the technology
An imaging unit works together with an optical module to access a screen - in which case the front window - map. A so-called organized collimator the beam path, while the projection must be reflective and translucent to allow the driver to review. The screen brightness is adjusted by a sensor to the ambient brightness and LEDs used as light source. The speed or engine speed indicator are always displayed as static information in the same place. Contact information is on the other hand so-called analog integrated into the environment - for example, the turn arrow is within the optical navigation on the road (see photo). These overlays fit thus to current situations - for example, collision warning with the BMW Head-Up Display with a red warning arrow will appear, as this would be on the road. BMW is all before which on its Web site in a Flash presentation.Safety aspects of head-up display
While riders throw Highway usual 100 km / h on glance at the speedometer, 27.78 feet pass, until the view is on the road again. That may sound a bit, but can have fatal consequences: Wild, a sudden traffic jam or even cyclists who are only now becoming visible, can lead to accidents. Is not considered yet an individual factor: the so-called accommodation, the time in which the eye is sharp, especially in the elderly which can take time.
While drivers in head-down display must lower their head, so to have the view from the road, the head-up display (HUD) is working directly in the field of view. By BMW 5 Series, the HUD system was in 2004 much more attention, but is now far more standard - many car manufacturers offer HUD to not and BMW lists this safety feature on many vehicles still within the special equipment, is only a few models BMW Head-Up Display, fitted as standard are included.
