What is virtual reality? 

Virtual reality (VR) typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real world environment or create an imaginary setting. 

VR also simulates a user's physical presence in this environment. VR has been defined as "a realistic and immersive simulation of a three-dimensional 360-degree environment, created using interactive software and hardware, and experienced or controlled by movement of the body”

We know the world through our senses and perception systems. In school we all learned that we have five senses: taste, touch, smell, sight and hearing. 

These are, however, only our most obvious sense organs. The truth is that humans have many more senses than this, such as a sense of balance for example. These other sensory inputs, plus some special processing of sensory information by our brains ensure that we have a rich flow of information from the environment to our minds.

How to get awesome virtual reality experiences?

Virtual Reality is used in wide range of systems such as headsets, omni-directional treadmills, special gloves and other hardware devices.  These are used to actually stimulate our senses together in order to create the illusion of reality.
This is more difficult than it sounds since our senses and brains are finely tuned to provide us with an absorbing experience.  If anything is even a little off we can usually tell. . And if you’re using virtual reality, you’ll listen to terms such as immersiveness and realism at different times. The problems in virtual reality experiences are partly technical and also partly conceptual. Virtual reality technology needs to take our physiology into account. For example, the human visual field does not look like a video frame. The peripheral vision is outside your vision, if it were gone you’d notice. Similarly when what your eyes and the vestibular system in your ears tell you are in conflict it can cause motion sickness. This is what happens to some people on boats or when they read while in a car.

Getting the best of VR apps

This may seem like a lot of effort, and it is! What makes the development of virtual reality worthwhile? The potential entertainment value is clear. Immersive films and video games are good examples. Media and the entertainment industry is trillion dollar one and consumers are always looking for innovation.  Virtual reality has many other, more serious, applications as well.

There are a wide variety of applications for virtual reality which include:

  • Architecture
  • Sport
  • Medicine
  • Arts
  • Entertainment

Wherever it is too dangerous, expensive or impractical to do something in reality, virtual reality is the answer. There are a wide variety of applications available for virtual reality from aviation to healthcare to take virtual risks in order to gain real world experience.

One of the most exciting parts for a iPhone app developer and Android app developer is being able to build your virtual reality mobile apps and then experience it for yourself for the first time

Experience virtual reality with mind-blowing features 

There are many different types of virtual reality systems, but they all share the same characteristics such as the ability to allow the person to view three-dimensional images. These images look life-sized to the person.

A virtual environment should provide the appropriate responses in real time, as the person explores their surroundings. The problems arise when there is a delay between the person’s actions and system response or latency which then disrupts their experience. The person realizes that they are not in a real-world environment and adapt their activities accordingly which results in an artificial, mechanized way of interaction.

In summary

Virtual reality is the creation of a virtual environment presented to our senses in such a way that we experience it as if we were really there. It uses an array of technologies to achieve this goal and is a technically complex accomplishment that has to account for our perception and cognition.

VR is used in games, entertainment and many other serious applications. The technology is becoming cheaper and more widespread. We can expect to see many more innovative uses for the technology in the future and perhaps a fundamental way in which we communicate and work thanks to the possibilities of virtual reality.


Realm data is compatible with Android mobile devices. It uses very little disk space, realm file perform better than SQLite or JSON. Here are the features of Realm database:


  • Realm is light weight database designed for mobile devices.
  • Replacement for SQLITE in mobile devices
  • It is a kind of No-SQL database
  • Fully Object Oriented.
  • Mobile-first written in C++
  • Cross platform support

Given below are the advantages of Realm 

  • 10X faster than SQLite
  • Easy to use - no need of query knowledge
  • Auto casting as a particular type

Given below are some of the disadvantages of using Realm

  • Still under development. However, Android app developers can proceed with released stable versions
  • Concurrent issue not handled    
  • No null support
  • No auto increment IDs
  • No mapping support - no foreign key
  • Migration is difficult

Integrating data in Realm

  1. Configuration
  2. Initialization
  3. CRUD operations
  1. Configuration
    • Single Module support
      • add the following to your app build.gradle file
      • compile 'io.realm:realm-android:2.3.1’ in your dependency
    • Multiple module support
      • add the following to your Project build.gradle file
        classpath "io.realm:realm-gradle-plugin:2.3.1" in your dependency
      • add the following to your app build.gradle file
        apply plugin: 'realm-android'

    thats it RealM configured in your project.

  2. Initialization
    • Init the Realm in your Application class and its custom configuration
      public class MyApplication extends Application {
            public void onCreate() {
            RealmConfiguration realmConfiguration = new                             
    • If you want can add database encryption by using application keystore file.
  3. CRUD Operations.
    1. A class can act as a table - query is not needed.
      Class Dog extends RealmObject{
              String key = "abc";
              int key = 123;
                  private int sessionId;
      • All the fields inside the class act as a column.
      • The field with @PrimaryKey annotation act as primary key for the table.
      • The field with @Ignore annotation can not be considered as a column - this filed ignored and no column is created for the filed
    2. Creating Entry.
      1. prepare UNMANAGED entries - does not having default entry in the table.
        Dog dog = new Dog();
      2. prepare MANAGED entries - can have its default entry in the table
        Dog dog = realm.createObject(Dog.class);;
    3. inserting into db
      • Get a Realm instance for this thread
        Realm realm = Realm.getDefaultInstance();
      • Before doing any write operation we must call
      • Do your write operation after beginTransaction.
        // Persist unmanaged objects
        final Dog managedDog = realm.copyToRealm(dog);
        // Create managed objects directly
        Person person = realm.createObject(Person.class);
      • After your write operation commit your updates into corresponding table

Examples :

  • Write operation
    Dog dog = new Dog();
    final Dog insertedRow = realm.copyToRealm(dog); 
  • Update operation
    dog.setName(“another name”);
    final Dog insertedRow = realm.copyToRealmOrUpdate(dog); 
  • Read Operation
  • Read Operation with conditions
    realm.where(Book.class).equalTo("id", id).findFirst();
                    .contains("author", "an")
                    .contains("title", "re")
  • Delete Operation
    // remove a single object
        Dog dog;
  • Truncate operation

Most of the densely populated cities all over the world have a high level of insurance exposure. These events resulted in the death of people and had significant economic effects on the areas impacted. The good news is cutting-edge mobile technology have not only made it easier for us to track and survive natural disasters, but salvage our property as well. Smartphone is not only a “lifesaver”, but the current crop of insurance-related apps can actually settle your claims as well. Insurance solutions can easily and quickly manage key claims processes and reduce claim costs significantly. Insurance app is designed to automate and digitize core claims processes in order to widen its reach and increase customer satisfaction.

An example of natural disaster happened in 2013 St. Jude Storm. The hurricane blasted Europe with wind speed of 120.8 mph (194.4 km/h) on 28th October, 2013. It devastated Britain, Germany, Netherlands, and Denmark resulting in several deaths and causing extensive damages to the infrastructure. These densely populated regions of Europe have a high level of insurance exposure. The insurance industry would have incurred costs of £370 million, according to a data from the Association of British Insurers.

A leading insurance claims management company based in Copenhagen turned to Anubavam to devise a mobile solution for natural disasters, which was certainly a challenge to the company. Anubavam identified the need to modernize its existing mobile app development process and create an app which could maximize the sharing of information among insurance assessors and craftsmen for processing claims. As a result, the insurance app was successfully used during the St.Jude storm to manage the insurance claim process. Using the in-built camera within the mobile app, all-in-all 100,000 photos were taken and 30,000 photos during cyclone were taken by assessors and craftsmen for processing claims from the scene of the incident to estimate lost or damaged items and attach it to the report. During the calamity, 2000 users downloaded the mobile app and got their insured claims settled easily. Now, the app has more than 5000 downloads. The key features of the app includes pencil-drawing sketch on photos, image editing tools, unique URL to web application and video editing. Mobile app solutions enables users to access content offline with the option to automatically sync your files when you have network connectivity. The insurance app is a perfect tool for handling major disasters with the simple and user-friendly claims management solution. Here are some of the important features of the insurance claim handling app:


  • Separate login for insurance handler and claimant
  • Login & edit details of the claim
  • View assignment of tasks 
  • Take pictures with camera and/or from archive in phone
  • View reports created by agents, craftsmen and other participants
  • View settlement overview
  • View participants on the claim
  • Send messages and call participants
  • Search claim address using Google Map
  • Offline storage
  • Video trimming while uploading the video of damaged property 

Once you’ve got your mobile app, you may actually be able to safeguard your home and property during emergency and non-emergency situations with the tools and instant alerts to keep you well prepared until the big one hits.
