Virtual Reality and Augmented reality concepts are interrelated to each other. Virtual reality deals with the creation of an artificial world that can be experienced by a person through feedbacks such as sense of vision, through audio and illusion of tangibility. Rather creating artificial world around us completely, it focuses on supplementing the real world. Augmented reality as the system combines real and computer generated information in a real environment.
It is capable of merging physical environment with the information which apprehends to be real by all human senses. For Visual reality computer generated graphics are overlaid on real objects with the help of display and tracking technologies.
Location based AR (Using GPS etc.)
The latest mobile and computing devices have made location based computing and location based services more effective. These have paved ways to new possibilities in the way information is gathered for doing business. It has opened up new horizons in the way people interact with the electronically enriched world around us. But in order to achieve this it demands higher accuracy with precise orientation tracking.
Usually these days we use GPS installed in our mobile and advanced prototypes in outdoors for tracking positions. Indoors we use ceiling-mounted trackers and several hybrid schemes.
The scope of such futuristic scheme is enormous. It can be observed that the MARS (Mobile Augmented Reality Systems) scheme can be applied to determine the position of important things that are to be virtually annotated.
The MARS and Windows Icons in Augmented Reality
There is a substantial difference in the interfaces possible in mobile advanced systems and Windows icons. Windows icons are studied well, and understood. On the other hand, it is essential to develop UIs in MARS that makes the interaction more useful under different circumstances. There are many issues which need to be addressed such as incoming messages or varying tracking accuracy which makes it even more complicated to maintain a usable composition.
With reference to the issues addressed above, many research steps have been taken:
- All the possible UIs and a set of interfaces were researched
- On the basis of research and other explorations, a classification of its interface was developed
- To make the UI user friendly and keep it simple, UI management techniques were developed
- In order to allow AR views to adjust itself in the dynamic situations, a rule based reasoning architecture was designed and developed
Attributes of MARS Interfaces
There are many differences in which augmented reality presents itself when it comes to interacting with people. In addition, it also differs majorly from other styles of computer interaction, such as virtual reality and other computing interfaces.
One peculiar characteristic about MARS is its existence in the real world. This raises several issues -such as the control which is unlike a desktop UI wherein the only way of interacting is with its well defined techniques. Scene dynamics is another aspect and a major concern because of the unpredictable dynamics. Consistency also needs to be addressed as the physical and virtual world needs to be consistent with each other. A concrete semantic relationship must be established between physical and virtual objects in order to classify the UI behaviors. And finally display space should be sufficient which would satisfy or match the need of the user.
There are high constraints when it comes to the management of MARS UI. Keeping in mind the dynamic nature and constraints it is necessary to react efficiently to the changing context of user situations.
