       SUMMARY OF THE INVENTION  
       [0004]     The current invention provides augmented information on the go while reducing the hazards and risks that are related to using personal communication and computing devices while driving a vehicle. People are spending significant time within cars. In many cases using personal communicating and computing devices while driving force the driver&#39;s eyes off the road in order to watch information such as caller identification of a received cellular phone, viewing and flipping through a mobile address book before making a call, watch driving directions, view maps, or receive a textual, pictorial, or multimedia messages and information.  
         [0005]     The Head-up Display (HUD) systems are well known and are being used for various mobile applications. Current invention diminishes at least some of the disadvantages associated with methods and solutions for displaying mobile and cellular information in a mobile environment. It enables Head-up Display (HUD) systems to be easily and seamlessly utilized with mobile applications.  
         [0006]     Addressing the hazards of using cell phones while driving, modern car kits offer today wide remote LCD displays that are installed on the dashboard to enable the driver to view the cell phone parameters such as his address book with minimal diverting of his eyes. The large remote LCD display has not solved the need of the driver for changing his eyes focus from long to short range and visa versa, the need to view that data in a different light conditions and the additional eyes focus diversion all these components maintain the risk of using a cell phone while driving even with a large remote display.  
         [0007]     Some lucrative cars have built in HUD systems that are wired to built in car systems such as Infra red imaging and navigation systems. Most cars do not have such HUD systems. Adding a HUD to a car would require complicated hardware and software interface and expensive wiring that would enable the HUD system to communicate and display a personal communicator data.  
         [0008]     In one embodiment of present invention, a system that provides a vehicle&#39;s driver with, an augmented information and data within his Field-Of-View (FOV). The augmented information is wirelessly received from the driver&#39;s communicating or computing apparatus. Such a wireless apparatus can be a cell phone, a PDA, an infotainment (information-entertainment) system, a mobile computer, or a navigation system, or another infotainment (information-entertainment) system, such as satellite radio (i.e. XM-radio)  
         [0009]     It would be appreciated that current invention provides seamless connectivity between the personal, portable communicating or mobile computing apparatus and a wireless HUD, which enable vehicle&#39;s drivers to easily and safely utilize their handheld communicating and computing devices while in the car and without taking their eyes off the road.  
         [0010]     In another embodiment of present invention, a HUD that received image information from a portable computing or communicating apparatus and automatically reformats the images, text or video to match it to the HUD optical properties such as resolution and image size.  
         [0011]     It would be appreciated that current invention enables seamless ubiquitous connectivity of the wireless HUD of current invention to most personal wireless communicators and portable computers. As a result layman would easily be able to install the wireless HUD and safely use it and by doing so, would increase safety driving. The wireless installation requires no wires and will keep the driver space free of wires.  
         [0012]     In another embodiment of current invention is the HUD capabilities of getting into the drivers FOV on demand only and its ability to be dismissed on demand or on sever event such as a car collision. Yet in another embodiment of current invention is the HUD capability to automatically adjust the projected image intensity to match the visual conditions in the user&#39;s FOV  
         [0013]     In another embodiment of current invention is the wireless HUD is connected to personal portable GPS enabling these portable devices to safely display augmented data such as maps and driving directions to the driver within his FOV and without taking his eyes off the road.  
         [0014]     In another embodiment of current invention is the wireless HUD is wearable and is wirelessly connected to computing apparatuses such as personal computer, or infotainment (information-entertainment) system, or personal communicators or servers, enabling the user to wirelessly receive and augmented watch data and information that is received from these devices without the need to carry computers with him while performing his job and while enabling use both his hands for his tasks.

Such a wired link may be a USB, USB2Go, and serial link such as RS232, parallel link, optical, or a proprietary link.  
         [0043]     Processor unit  200  receives images data to be displayed on the HUD. The Processor unit  200  processes this data and prepares it to match the projector display  212  parameters, so it would fit the projector display and the optical system, which comprises the HUD. In some cases, the processor  200  will also compute the adjustments that are needed to correct optical HUD system optical distortions due to lenses, reflectors, and light waves propagation. The image that is generated by the Processor unit  200  is transferred to the Projector display  212 . The Projector display  212  may be of a transparent LCD type. A light source and a diffuser  210  radiate light waves  216  through the Projector display  212  and via the optical adaptor  214 , that may be only a covering protecting transparent material, or may also has optical transfer function. The projected image light waves  220  are directed to the reflector visor unit  232 . The reflector visor unit  232  preferably can be of polycarbonate, a glass, a plastic, acrylic, or other transparent materials. Preferably the visor will be coated with a partly reflecting material, or colored, so it will function as a semi-transparent reflector. The reflector visor unit  232  preferably is shaped with optical gain such as parabolic, aspheric, or other shapes that would provide optical gain. Though it may also have no optical gain. The reflector visor unit  232  is preferably used as a reflecting lens of the projected image while being transparent to the images that are within the Field of view (FOV) of the vehicle operator&#39;s eyes  103  of  FIG. 1 . Alternatively the reflector visor unit  232  may be a foil that is attached to the vehicle&#39;s windshield in order to prevent double image, in such implementation there is no optical gain at the visor unit  232 . The Visor reflector  232  may also be part of the windshield. It may be embedded within the windshield itself such by using optical materials such as DuPont&#39;s Butacite® wedged PVB interlayer. The projected images  108  that are reflected from the reflector visor unit  232  provides the vehicle&#39;s operator an augmented image of the images of the information as received from the Communicator  118  to be displayed overlaid with the images, which are within his FOV in front of the Vehicle.
