COMPUTER-GENERATED WORLDS Augmented and virtual reality are often part of the same conversation, though there are significant differences between the two technologies. It provides textual, symbolic, or graphical information that holds a real-time relationship with a situation or surrounding. other provides a complete replacement to our visual world. Augmented reality ( AR ) is an enhanced version of the real physical world that is achieved through the use of digital visual elements, sound, or other sensory stimuli delivered via technology. Although the term Augmented reality is relatively new, early developments in the technology can be traced as far as 1900s. Howard Grub, an Irish telescope maker patented a device called the collimating reflector. It’s main purpose was to enable greater accuracy when shooting firearms by augmenting the crosshair view exactly at the user’s target vision. It tried to solve a pertinent challenge of the human eye of being able to focus only at one object at a time. Grubb’s invention inspired the development of a number of military gun sights

Head up displays (HUD) As the onboard controllers on flights became more complex, the information processing tasks for pilots increased with added number of sensors, avionics and flight controls. It is important for pilots to focus on what is happening outside rather than looking at the array of information inside the cockpit. Heads up displays were mainly invented for mission critical applications like flight controllers and weapons system dashboards. Critical information is projected on transparent screens mounted in front of the pilot. This enables pilots to look forward outside rather than looking down inside the cockpit. Like Grub’s collimating reflector, HUDs tried to solve the problem of shifting focus by using a type of collimating projector. The information projected is collimated (parallel light rays) focused on infinity so that the pilot’s eyes do not need to refocus to view outside the cockpit.
A regular HUD contains three main components; a projector unit, a viewing glass (combiner) and a computer (symbol generator). HUDs help increase situational awareness by reducing the shift of focus for pilots. Increasingly heads up displays have been finding ways into new automobile designs.
Helmet mounted displays
The next logical step for heads up displays was to move from the windshield to the helmet. Increasingly helmet mounted displays which use the same underlying principles of heads up displays are being used in aviation and other industries. Holographic displays Popularized in the Star wars series, Minority report and the Iron man series in the recent times, these type of displays use light diffraction to generate three dimensional forms of objects in real space. The fact that holographic displays do not require users to wear any gear to view them is one of their greatest advantages. These type of displays have always been in the realm of science fiction and have recently started gaining traction with products like Looking Glass and Holovect. Get started Open in app Open in app
