Two people on the car surely have different concerns in mind; more particularly when they’re respectively sitting on the front and the back; For instance, when driving your car, you need information from the GPS navigation system which of course your children on the back don’t care about; all they need is watching DVD cartoon movie.
And now, the new device by LAND ROVER is to indulge both the driver and passengers as it provides completely different images simultaneously. Unlike the SPLITVIEW of Mercedes Benz S Class Summer 2009… which splits the screen, this 12-inch touchscreen infotainment system incorporates the patented PARALLAX BARRIER TECHNOLOGY to displays two images in the same screen depending on the viewing angle. The technology alternately hides and reveals columns of pixels to the left and right hand views of the screen.
Well, I think Wikipedia’s explanation can help you understand how the technology works. This image will give a simplified illustration of the parallax of an object against a distant background due to a perspective shift. When viewed from “Viewpoint A”, the object appears to be in front of the blue square. When the viewpoint is changed to “Viewpoint B”, the object appears to have moved in front of the red square.
Unveiled at the NEW YORK AUTO SHOW, this World first ‘dual view’ screen technology is to first being installed on the next 2010 RANGE ROVER. The display comes with a specially designed agar coating to help prevent sunlight bleaching. This HDD-based navigation system is also equipped with voice command system to complements the touch screen technology in controlling all the functions such as satellite navigation, DVD video, audio system and climate control. It also provides the must-installed features of USB socket and a dedicated iPod port.
If you cross on this device but not the RANGE ROVER (for certain conditions), then you might need to wait for the aftermarket products soon enough. You just have to be patient. Anyway, it’s worth waiting for.
Little more about parallax by Wikipedia
Parallax is an apparent displacement or difference of orientation of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. The term is derived from the Greek παράλλαξις (parallaxis), meaning “alteration”. Nearby objects have a larger parallax than more distant objects when observed from different positions, so parallax can be used to determine distances. In astronomy, parallax is the only direct method by which distances to objects (typically stars) beyond the Solar System can be measured. Here, the term “parallax” is the angle or semi-angle of inclination between two sightlines to the star.
