The mirrors on the driver's side of every modern car have a field of view of about 15 to 17 degrees wide -- the angle between two adjacent numbers on a clock face -- offering a narrow slice of what's going on behind the car. It's easy enough to make a mirror that curves for a wider field of view, as passenger-side mirrors do, but that curve distorts the image, which is why passenger side mirrors always warn riders that objects are closer than they appear.
There are many researches going on this Blind spot detector using costly sensors installed on the car rear view mirrors that could tell the driver of the car crossing so that he becomes aware. The phenomenon is believed to work like a blinker with a sound installed with sensors and thus intimate the driver about the vehicle crossing on its side in time. Company like Motherson Sumi are working on this one.
Professor Hicks has invented a slightly curved mirrors which does not distort the image like other curved mirrors while offering a whopping 45 degree view of the happenings on the rear of the car. This mirror features a surface that has many smaller mirrors that function like disco balls to work together through an algorithm that allows the mirror to display a significantly wider angle than conventional rear view mirrors. The mirror that Professor Hicks has invented has already been patented with many companies showing interest in this technology.
The technology if proves to be an efficient one will save lots of money, at least of the end users as the Blind spot detector's gonna be a costly phenomenon.
