Augmented Reality - Project One - History

I have continued to do research on my Augmented Reality assignment throughout the week.
Here is some information I found on the history of invisibility technology.
The following information has been typed by me and is included in a .pdf I will be placing into drop box and providing a link to the file.

History of Invisibility Technology

Ever since humans have used stealth, we have been on a quest to become invisible. The idea of being invisible stretches back centuries, before today’s technology existed. Histories greatest assassins could make themselves disappear, without really disappearing.

These assassins were called ninjas, and began developing the art of invisibility as far back as the 6th century. Ninjas used their ability to hide in the blind spots of human sight in order to assassinate their targets.




Ninjas are able to exploit weaknesses in the human eye. The normal field of vision in each eye extends to 60 degrees ahead, and peripherally up to 100 degrees outward, but when we focus on something, the brain moves the centre of vision toward that area of interest, shrinking the overall field of vision to as little as 6 degrees and making us blind to most of our surroundings.

A ninja would wait until the time when their victim would focus their gaze on something, leaving them blind to their surroundings and giving the ninja that split second to attack.











This was an early way to achieve invisibility. 500 years later the British became closer to achieving true invisibility, with Deception Camouflage. In 1942, during World War 2, Winston Churchhill managed to make the Suez Canal and the Port of Alexandria appear invisible from the skies.

They did this by constructing a fake harbour 3 miles away from the Port of Alexandria. The fake harbour even included a fake lighthouse, fake buildings and fake anti air guns with light flashes to simulate gunfire. They then blacked out the real Port of Alexandria and light up the fake harbour in order to trick the Germans into bombing the false target.

During World War 2, the Americans also allegedly carried out an invisibility experiment. Codenamed Project Rainbow, the experiment would come to be known as the Philadelphia Experiment. The Philadelphia Experiment was an investigation into Albert Einstein’s theory on how to somehow create an electro magnetic envelope around a ship in order to make it radar invisible.
