TECHNICAL FIELD
[0001] The present disclosure relates generally to an augmented reality based training system. More specifically, it pertains to an augmented reality based training system which provides a simulator environment for providing training to defence personnel.
BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Training is enhancing knowledge, practical skills, capability, capacity, productivity, and performance of individual or group in a specific area. Moreover, the training required for a profession, trade can continue beyond competence to update and upgrade skills of a particular field. For training various type of colleges, technical institute, and professional schools hire experts from same field and provide training to the interested individual or group. Training in specific areas such as military application, sports, job instruction training, vestibule training, refresher training, apprenticeship training, induction training, martial art training etc. are provided for skill development.
[0004] There is not a single organization on earth that can survive without well-trained members. A training program allows to strengthen skills that each employee needs to improve; the training session brings all employees to a level so they all have similar skills and knowledge in their respective domains.
[0005] Military or Police training is a process which intends to establish and improve the
capabilities of personnel in their respective roles. There are many technical tasks in military
training that are too dangerous, many of which carry life or death risks in real world learning.
Workplace training accidents are, unfortunately, common occurrences in defence, they may
even be fatal or injurious to life. As novices are the most likely to make mistakes, the novices
need safe and secure training methods to practice their skills for gaining confidence.
[0006] Traditional training practices are expensive since lots of resources like guns,
bullets, and targets are required for the training of military people. Many scenarios and real time war like situations are also inconvenient to practice in real life. For example training of troops for situations like world wars, training the troops for Line of Control (LOC)

operations, or the like. Twenty-first century military challenges are both conventional and asymmetric in nature demanding evolution of innovative digital technologies for training. [0007] There is, therefore, a need in the art to provide a simple, convenient and cost effective augmented reality based training system for safe and secure training. [0008] As used in the description herein and throughout the claims that follow, the meaning of "a," "an," and "the" includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of "in" includes "in" and "on" unless the context clearly dictates otherwise.
[0009] The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. "such as") provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.
[0010] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all groups used in the appended claims.
