Augmented Reality: The Perception Of The Purpose Of Augmented Reality

702 Words3 Pages
Augmented Reality (AR) is a real time direct or indirect view of the physical real world that is enhanced or augmented with computer generated information. AR is both interactive and registered in 3D, combining real and virtual objects. AR enhances a user’s perception of the real world and the way they interact with it. The augmented Reality’s main purpose is simplifying the user’s life, by bringing virtual information to their immediate surroundings through an indirect view of the real-world environment. Although augmented reality is like Virtual reality (VR), AR is an enhanced view of the real world, where VR is a pure virtual environment.

The information can also simply have an entertainment purpose, such as hands-free games or mobile augmented reality. There are many other classes of AR applications, such as medical visualization, entertainment, advertising, maintenance and repair, annotation, robot path planning, etc. There are three major types of displays used in Augmented Reality: head mounted displays (HMD), handheld displays and spatial displays. HMD is a display device worn on the head or as part of a helmet and that places computer generated images (CGI) over the real and virtual environment of the user’s view. This is accomplished by projecting CGI through a partially reflective mirror on the lens of the HMD, thus allowing the user to viewing the real world and at the same time see the augmented world too. Handheld displays are computing devices with a display that the user can hold in their hands. Video-see-through techniques overlay graphics onto the real environment and employ sensors, such as GPS units, Microelectromechanical systems (MEMS), and accelerometers for their six degrees of freedom tracking. Currently smart-phones and Tablet PCs are the most popular types of handheld device. Smart-phones and tablets are very portable and have many capabilities. They are becoming increasingly more powerful with advances in their hardware and software capabilities. This makes them a very
