1. A head-up display system for representing an object in a space external to a vehicle, comprising:
- a position system for recording a position of at least one of the passengers of the vehicle;
a projection unit for projecting a correct-location representation of the object, the correct-location representation including a marking configured to surround and be spaced apart from the actual object as seen by the at least one of the passengers of the vehicle, and for fading in a symbol into a direct viewing range of a driver of the vehicle in a location different than that of the projection of the correct-location representation, the symbol representing the object;
a sensing arrangement to sense the object in the space external to the vehicle; and
a computing unit for receiving sensed object data from the sensing arrangement and recognizing a pattern in the sensed object data to generate the symbol representing the object as a function of the sensed object data and symbol data stored in a databank,wherein the computing unit can recognize patterns associated with traffic signs, pedestrians and vehicles to generate corresponding symbols.
