What is Augmented Reality?


Augmented reality(AR) can be described as the use of technology to overlay information on the real world that we can see. It is akin to virtual reality, but it aims at replicating the real-life environment on a computer. For instance, it superimposes sounds and images over what a user hears or sees. A good example of augmented reality and its defining concept of interactivity is what can be observed in the ‘Ironman’ movies.


To many of us, augmented reality may appear to be very futuristic technology, but this may not be entirely true. Technology that applies some form of augmented reality has been with us for some years now. Looking back to the 90s,a lot of fighter aircraft were equipped with heads-up displays that displayed information pertaining to the plane’s altitude, speed and direction.Later, the displays were improved to show the pilot which objects appearing in the viewing field were to be considered targets.


Even further back in 1965,Ivan Sutherland of the University of Utah and a pioneering computer scientist gave a description of a wearable gadget that used a head-mounted display unit that employed half-silvered mirrors which allowed the wearer to view a virtual world that was overlaid on the real world. Three years later, he demonstrated his idea, and it was nicknamed the ‘Sword of Damocles’.

Over the last couple of years, a number of companies and tech labs have attempted to design devices that provide users with augmented reality. In 2009, Media Lab’s Fluid Interfaces Group of The Massachusetts Institute of Technology developed a device called the SixthSense. It hangs from the chest of the user and it uses a tiny projector, a mirror and a smartphone. There are four sensors on the fingers of the user through which they can manipulate the images that are projected by the device.

In 2013,Google Glass was rolled by Google, turn


ing the focus of augmented reality towards the more wearable interface of glasses. The device features a small screen on the lens through which a small projector displays images. It responds to voice commands and superimposes videos, images and sounds on the screen. However, the device was pulled from the market in December 2015- but plans are underway to design a new version.


In the recent past, various augmented reality applications have been developed for a number of industries. This has been helped by the increase in the popularity of smart devices and the general advancement in computing technology. This means the technology has immense potential in the consumer world of today. Education and gaming are two major areas that have experienced a lot of commercial growth in augmented reality. PlayStation and Xbox, the major video game consoles have incorporated augmented reality features in their last two generations of consoles.

In education and medicine,augmented reality using 3D models is being applied to enable better understand human anatomy or even help in surgery using infrared scanning imagery. In the military, heads-up displays can view information that is tagged onto real world objects.
Mobile phones like the iPhone have apps that enable users to view computer generated images that are overlaid on real life images. For instance there is an app that can help you locate a restaurant by displaying restaurant logos as you move in a specific direction.

The future

The cost and size of the basic apparatus needed for augmented reality such as computers, cameras and connectivity is reducing. At the same time their accuracy, resolution and speed is increasing rapidly. This means we are headed to an era where wearable computers will become a trendy accessory, helping to mediate our interaction between the digital and analog worlds.

Stress is a term used when you feel that everything is becoming too much on you. In the medical world, stress can be referred to as a reaction to a destabilization of both physical and mental equilibrium. When under duress or whatever stressing situation you are in; the body undergoes a ‘fight or flight’ mode triggering the release of hormones such cortisol and adrenaline. Well, that is a jargon for those who never did biology but simple enough to make you understand.

Mark you; stress is a normal part of life if managed well but can get out of hand and cause adverse effect to your health.

What causes stress?

There is no single collection of things that can be said to cause stress. Some people are stressed by small things in their life while it takes a tragic thing for others to be stressed. While stress can be caused by a myriad of things, here are a few common causes you should be aware of;

  • Poor health: conditions such as diabetes, heart diseases and arthritis among others are known to cause stress.
  • Tragic losses: the loss of a family member, a close friend or someone you know could trigger harmful stress.
  • Family problem: family especially for the married can be an endless source of stress
  • Emotional issues such anger, lack of self control and low self-esteem cause stress in many people
  • Work related problems. Having a hard time at the work place is not easy to take. Most working people get their stress from their working environment and that transcends into their daily life.
  • Social problems such as keeping bad company and rejection by friends would lead to considerable stress.

Effects of stress

  • Lack of mind clarity and making wrong decisions
  • Chest and back pain
  • Obesity in children. With stress comes the craving for food. This is a direct ticket to obesity.
  • Erectile dysfunction. For the worst, stress can kill sex desire in anyone. Your libido goes down and you never rise for the occasion.
  • Lack of sleep. It is hard to sleep when you are stressed and that would take a toll on anyone.

How to manage stress

  • Positive thinking: even at the middle of problems you should see yourself as a winner. Do not give in to fate.
  • Keep good company: those around you would either help you deal with stress or make it worse. A good company is a plus if you want to beat depression.
  • Lead a healthy lifestyle: eating balanced diet, exercising, avoiding alcohol and finding time for fun would go a long way to help you evade or deal with stress.
  • Staying away from what stresses you. If you do some soul searching you will definitely find the things that stress you up. The solution is simple: stay away from them.

Consider The Following When Looking For A Dentist

dentistThere are many things that should be taken into account as you look for a dentist. You need to start by finding a Dentist that is going to be able to provide you with incredible services at a cut cost. There are many things that need to be taken into consideration as you are looking at different dentists, in order to find the right one for yourself. A few of the things that you should be taking into account when you are evaluating dentists include price.

Start By examining the price. A large majority of people are going to have dental insurance, which means that their insurance is going to be paying for most of their dental procedures. However, this is not going to be the case for everyone. There is always going to be some people that are going to have a number of problems, and they especially need to be paying special attention to the price.

Dental procedures can be very expensive. If you are not going to be able to pay for dental procedures, you need to find a dentist that is going to allow you to pay for things with the cash discount. If you do not have insurance that covers dental, then there is a number of options available to you. Sometimes, you can purchase only dental insurance for a very low cost, or you can agree to cover amounts of two a few hundred dollars, with only the larger examinations and surgeries coming out of the insurance. This can help you to reduce your rate, and still get the dental care you need.


Also, take the availability of any dentist into account. Remember that if you are having an emergency, you will often need dental work right away. This means that your dentist needs to be willing to be on call at times, or have a very flexible schedule with his other appointments. For instance, some dental surgeons are not going to be able to move appointments, which means that you will not be able to see the dentist for quite some time. You need to make sure that you can always get access to them when you require it, and that they are always going to work to ensure that you are able to get the care that you need, whenever you need it.


You should also be looking for a dentist that has a lot of experience in the field, as well as a lot of satisfied customers that have been happy with their work. If they are unable to provide you with exactly what you are looking for, then you should always be willing to make changes to your schedule. Take your time, and make sure that you are looking at all available options, and are not jumping to any conclusions throughout the process. Finding the right dentist can save you a lot of headaches down the road, so make sure that you are taking your time to find the right one now.
