AUGMENTED REALITY

Augmented Reality

Introduction

Augmented Reality (AR) is becoming a vital key for museums. Several artists have adopted this technique and expressed in semi permanent exhibitions. Industries are also taking advantage of augmented reality. These efforts are also limited to use the off-the- shelf- head worn displays. There are certain new techniques developed in augmented reality with new features, characteristics and flexibility. The terms cyberspace and virtual reality have become popular throughout current decade. The fiction movies such as Star Trek have aware the public about this concept. Most people see this world beyond their imaginations. This is also referred to as virtual environment in which people dive into the computer world with technological aspects.

Discussion

The virtual environment can control our senses such as hearing, smell, taste and haptics. There are various definitions of augmented reality according to different authors. Many authors consider Augmented Reality as a special case of Virtual Reality. Few authors argue that VR is more special case than Augmented Reality and Augmented Reality is the overall concept. In Augmented Reality, the physical environment is not fully suppressed as it is not the case in VR. The real environment is not easy to control as compare to the virtual environment. That is why there is always a difficulty in case of AR.

There are questions that cartoon display on TV screens and music play on the radio is Augmented Reality displays or not. Many people answer this as this is not an Augmented Reality display. There is a depth to understand this phenomenon. The augmented information should be strong in order to link with a real environment. The link should be a spatial relation between augmentations and real environments. The popular example of Augmented Reality science fiction is Princess Leia in Star Wars (Lion & Barfield, 1993, Pp. 483-486).

According to Ivan Sutherland, the ultimate display can control a room. A chair in this room would be liked to sit in, and bullet in such a room look likes a fatal. The programming makes this Wonderland on display in which Alice could walk. The technical Virtual Reality was proposed earlier in 1950s.

There are several technical difficulties and challenges related with Augmented Reality. A right and consistent registration between synthetic augmentations, which include three dimensions graphical elements and real environment, are the most important task to perform in Augmented Reality. The system has to determine the position of user in a moving environment ...
