In this post I would like to take a look backward and talk about how Augmented Reality began. Nowadays a lot of people know what is Augmented reality but, do they know how it was born?
Although Virtual Reality is much older than the 1980s or 1970s, older or nearly as old as the entire computer graphics field itself (in fact in 1956, Morton Heilig began designing the first multisensory virtual experiences), it wasn´t until late 1960s when it is considered as the beginnings. In 1968, Ivan Sutherland, an American computer scientist and Internet pioneer,and with the help of his student Bob Sproull, created the first virtual reality and augmented reality head-mounted display system, which was named The Sword of Damocles. This system used an optical see-through head-mounted display that was tracked by one of two different 6DOF trackers: a mechanical tracker and an ultrasonic tracker. Due to the limited processing power of computers at that time, only very simple wireframe drawings could be displayed in real time. So we can state that the field we now know as virtual reality (promoter of Augmented Reality), a highly multidisciplinary field of computing, emerged from research on three-dimensional interactive graphics and vehicle simulation in the 1960s and 1970s.
The term “augmented reality” was coined in 1992 to refer to overlaying computer-presented material on top of the real world. Tom Caudell and David Mizell discussed the advantages of Augmented Reality versus Virtual Reality such as requiring less processing power since less pixels had to be rendered.
From earliest 1990s to present, there have been a lot of new advances and significant improvements in the augmented reality field, not only for desktop solutions but also for mobile devices. Here we will show a short list that shows some of these advances:
