VIRTUAL REALITY
                 In Virtual Reality (VR), we create a virtual world that users can interact with. In this world, the

                 user cannot easily distinguish between what is real and what is virtual.
                 In both VR/AR, people must wear HMD (Head Mounted Displays) or
                 a VR Headset like Oculus Rift or the Google Cardboard. The headset
                 has two small video display screens one for each eye. This creates
                 a sense of three-dimension. You can also wear headphones and
                 gloves to experience VR and AR. The headphones play stereophonic

                 sound or even 3-D sound so that you can feel that you are hearing
                 sounds not only near the ears but also in various places around you. The gloves have sensors to
                 collect data about your hand movements. This equipment and the software give you interactive
                 sensory feelings, similar to real-world experiences.
                 Both AR and VR provide an immersive experience to the user. These technologies find the greatest
                 use  in entertainment,  sports/gaming,  close  interactive  eye-to-eye  communication  and aided
                 shopping experiences.

                 Imagine sitting at home and browsing through a store in London, where you can see and feel the
                 merchandise you wish to buy. This technology is also used in education. Imagine being an active
                 participant in a historical battle or a student of anatomy in medical school. You can really feel the
                 battle or touch the organs.
                 We must remember that the journey of VR started in the 90s with the Nintendo Virtual Boy, but it
                 really did not catch on. Now, the case seems different as the means of experiencing AR/VR has

                 become less expensive. Also, there is a lot more on offer and we are all connected all the time at
                 least via our smartphones.

                 VR Simulator devices represent the behaviour of physical or abstract
                 systems. VR Simulation technology is used in training. It is used to
                 train  bus  drivers and  pilots.  Surgeons  can  develop  their  surgical
                 skills through simulation on digital patients. Architects can create
                 a walk-through model of their projects. VR therapy is also used to
                 treat autistic children and phobias.




                           INTERNET OF THINGS

                 The Internet of Things (IoT) has become a buzzword nowadays throughout the world. It is a
                 system of connected computing devices, mechanical and digital machines that create a virtual
                 network where a monitoring centre ensures that everything is working smoothly. Each connected
                 device has a unique identifier and can transfer data over the network without any human
                 intervention. The connected devices gather and share data about their usage and their
                 operative environment. The devices can be your smartphones, refrigerators, televisions, washing
                 machines, etc. You must have heard about smart cities. They can be developed with the
                 optimised waste management systems, traffic systems and efficient energy use, enabled by IoT.
