As far as technology goes, we live in the best times in the history of mankind. We live in a time where things we see on TV are increasingly becoming real. Some of our favorite sci-fi concepts have found their way from the TV screens to the real world. One of our favourite fictional ideas is virtual reality. Well the enthusiast, virtual reality is no longer a thing of fiction. A lot of top tech companies have been toying with virtual reality technology for a while now.
This article is meant for virtual reality fans and those that do not know what it’s all about. Read on to the very end, you are guaranteed to learn a lot about what virtual reality is.
What Is Virtual Reality?
So, what is virtual reality, and what is it all about?
Virtual Reality (VR) is a computer-generated environment with scenes and objects that appear to be real, making the user feel they are immersed in their surroundings. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences are the availability of content and cheap computing power.
Is There a Difference Between Virtual Reality and Augmented Reality?
While both these concepts are built around simulation, there is indeed a difference between the two. Think of augmented reality as an inverted virtual reality. Are you still having trouble picturing it? Let’s take it a step further.
Augmented reality involves the simulation of virtual objects in the real world, your physical environment while virtual reality simulates an environment for you to inhabit.
In Augmented Reality, the computer uses sensors and algorithms to determine the position and orientation of a camera. AR technology then renders the 3D graphics as they would appear from the viewpoint of the camera, superimposing the computer-generated images over a user’s view of the real world.
In Virtual Reality, the computer uses similar sensors and math. However, rather than locating a real camera within a physical environment, the position of the user’s eyes is located within the simulated environment. If the user’s head turns, the graphics react accordingly. Rather than compositing virtual objects and a real scene, VR technology creates a convincing, interactive world for the user.
What Are Some of the Ways Virtual Reality Is Applied?
1. Virtual Reality in Sports
Professional sports teams, in particular, are investing in virtual reality to obtain a competitive advantage. Coaches in the NFL and collegiate football are introducing virtual reality technology into their workouts to prepare for games. Virtual reality is being used by NASCAR drivers and soccer teams to retrace their steps and learn from their mistakes.
When it comes to fans, virtual reality is all about new experiences. Users can view highlights from the perspective of a player in the NBA.
2. Virtual Reality in Retail
Online purchasing is convenient, but it frequently requires us to buy first and then try. However, virtual reality allows you to preview furnishings in your own home and test on makeup on your actual skin. Customers will have a better experience as a result of this, and returns will be reduced.
Retailers can deepen engagement with current and potential customers by bringing VR to the next level. They can collect data to sell and customize each user’s buying experience.
3. Virtual Reality in Automotive
In the automotive industry, virtual reality encourages experimentation over a pricey prototype. Ford is utilizing virtual reality technology to bypass the 2D drawing step and go into a 3D model. When creating and redesigning external and interior components, saves time.
Audi and Tesla, for example, are taking this a step further with their virtual showrooms. Users can use their headsets to explore new features and adjustments while driving.
4. Virtual Reality in Healthcare
Virtual reality technology has been widely adopted in the healthcare industry. It aids in the training and preparation of their specialists for real-world scenarios, such as surgery. Complex operations can be planned out by groups. They can even diagnose and cure patients created by computers.
Virtual reality is also being utilized to investigate mental health therapy options. It’s been used to cure a variety of conditions, including alcoholism, claustrophobia, depression, and more. Because headsets may be used in the comfort of one’s own home, they can be a safer and more cost-effective solution for many clients.
5. Virtual Reality in Education/Training
Students were compelled to learn online due to the pandemic. While technologies such as Zoom can help with collaboration, they frequently fall short. Virtual reality can be beneficial. It has the potential to increase student involvement and attentiveness.
But virtual reality isn’t just for academics. Retailers, IT firms, and even the military are utilizing tools to assist in the training of their employees.
What companies are heavily involved with the production of virtual reality technology?

Have you ever looked at a digital photo and felt like bringing it to life? A lot of us have. What if I told you this idea is no longer fantasy, and that it is in fact now a reality? That’s right; you can turn two-dimensional images into 3D, all with the help of 3D printing.
So what exactly is 3D printing?
3D printing is the process of making 3D objects from digital files, this is also known as additive manufacturing. It is called additive manufacturing because it employs additive processing to create the 3D objects. It involves layering materials, like plastics, composites, or bio-materials to create objects that range in shape, size, rigidity, and color. Of course, all of this is done by using a 3D printer. It’s amazing that the world has gone from printing papers and magazines to printing 3D objects.
What is a 3D Printer?
3D printers are part of the additive manufacturing family and use similar methods to a traditional inkjet printer- albeit in 3D. It takes a combination of top-of-the-line software, powder-like materials, and precision tools to create a three-dimensional object from scratch.
These printers have extreme flexibility in what can be printed. They can use plastics to print rigid materials, like sunglasses. They can also create flexible objects, like phone cases or bike handles, using a hybrid rubber/plastic powder. Some 3D printers even have the ability to print with carbon fiber and metallic powders for extremely strong industrial products.
What is 3D Printing Used For?
So we know what 3D printing is and what it is used for, now we move to the uses of 3D printing. This glorious piece of technology is slowly reshaping a lot of heavy-weight industries around. It is clear that this tech is here to stay and will only get bigger and better with time. Here are some of the top uses of 3D printing:
1. Rapid Manufacturing and Prototyping
One major use of 3D printing is rapid manufacturing and prototyping. A lot of industries use it to create prototypes at little to no cost whatsoever. The process of creating prototypes in a very short amount of time is called rapid prototyping.
3D printing provides companies with a low-risk, low-cost and fast method of producing prototypes that allows them to test a new product’s efficiency and increase development without the need for expensive models or proprietary tools.
2. Aviation
Another use of 3D printing can be found in the aviation sector. The aviation sector is also part of the heavy sectors that have used 3D printing technology to increase efficiency and cut costs. GE Aviation has 3D-printed 30,000 Cobalt-chrome fuel nozzles for its LEAP aircraft engines. They achieved that milestone in October of 2018 and considering that they produce 600 per week on forty 3D printers. By 3D printing fuel nozzles, GE Aviation saves a whopping $3million per aircraft.
3. Construction
I know what you might be thinking; “is it even possible to 3D print a whole building?” the answer is a resounding yes! This is already being employed by a number of construction companies. Some companies 3D print parts prefabrication while some do it right there on site.
The first fully completed residential building was constructed in Yaroslavl, Russia in 2017. 600 elements of the walls were printed in a shop and assembled on-site, followed by completion of the roof structure and interior decoration for a total area of 298.5 sq meters (3213 sq ft). The project represents the first time in the world the entire technological cycle had passed building requirements, from design, building permit, registration, to connection of all engineering systems. The building was not built just for presentation, today a real, normal family lives in it.
4. Medicine
The healthcare center is probably the sector that has been the most affected by 3D printing. 3D printed prosthetics exemplify 3D printing’s versatility. It is difficult and expensive to produce prosthetics that fit a patient. With 3D printing, measured prosthetics can be modeled and printed at a significantly lower cost. Children in need of a prosthetic formerly had to wait to get one to be sure they would not outgrow it. Now, a new prosthetic can be 3D printed for them every few months. In some third-world countries, prosthetics are not even an option, they can now take advantage of 3D printed ones.
5. Education
You know a piece of technology has groundbreaking positive effects if it makes its way into the educational sector. Educators and students have long been using 3D printers in the classroom. 3D printing enables students to materialize their ideas in a fast and affordable way.
3D printers are now commonly found in classrooms and public libraries. Universities have 3D printers available for students to use in classes and projects. Companies such as MakerBot offer certification courses in 3D printing applications for both educators and students.
Graphic design students can easily construct models with complex working parts. Students in the sciences can create and study cross-sections of organs in the human body as well as other biological specimens. Chemistry students can make 3D models of molecules and chemical compounds.
Types of 3D Printing
There are several types of additive manufacturing, although The American Society for Testing and Materials (ASTM), developed a set of standards that classify additive manufacturing processes into 7 categories.

Big data is a field that treats ways to analyze, systematically extract information from, or otherwise, deal with data sets that are too large or complex to be dealt with by traditional data-processing application software. Sounds too techie and complicated, does it not? Worry not, in this article we shall break down what Big Data is in simpler, easier terms that could be easily understood for none-techies.
First off, you have to understand what data is. It might sound a bit weird seeing as you use that word so many times in the space of 24 hours, but you’ll be surprised. Also, if you defined data as information, guess what! You got it wrong.
Data and information are in fact not the same as there is a fine line between the two.
What Is Data?
Data is an individual unit that contains raw materials which do not carry any logical meaning. The symbol ‘!’ Is an example of data, but you see on its own, it carries no meaning.
Information is a group of data that collectively carries a logical meaning. What’s more? Data doesn’t depend on information, but information depends on data.
Remember, we’ll break it down into very simple terms and leave out the overly complex parts.
So, data is unorganized and unrefined facts. Information comprises processed, organized data presented in a meaningful and logical context. So it’s safe to say that without data, there will be no information, but without information we can still have data, which is the raw material.
Think about it like raw material and finished products.
Let’s take Wood and Paper for instance. Wood from trees is the raw material (data) and paper gotten from the processed wood is the finished product (information). You see, the paper (information) depends heavily on the raw material, wood (data) in order to exist. Basically, that’s the relationship between data and information.
What Is Big Data?
Big data is simply a collection of data that is too huge and yet continues to grow with time. It is data that is so large and complex that none of the typical data management tools can store it or process it properly.
Do not be confused, Big data is also data but with huge size.
Why Is Big Data Important?
Now that we know what Big Data is, the next question would be “Why is Big Data important”? You want to know what the big deal about big data is.
Firms use big data analysis to improve operations, provide better customer service, create personalized marketing strategies and take other actions that can increase revenue and profits. More so, businesses that use it effectively have a potential competitive advantage over those that don’t see as they’re able to make faster and more informed business decisions based on the data analysis.
Simply put, companies that use big data have access to more vital information and can make smarter business moves compared to companies that don’t use big data.
Big Data isn’t only used in the financial sector, it is used in a variety of fields such as medicine, energy industries, manufacturing and transportation services, and other government uses which include emergency response and crime prevention.
Types of Big Data
There are three types of Big Data and they’re:
- Structured big data
- Unstructured big data
- Semi-structured big data
1. Structured Data
Structured data, just as the name implies, is a set of data that is organized. It is quite easy to work with because all its dimensions are defined by set parameters. A typical example is what you see on a spreadsheet but on a much larger scale.
So, essentially any data that can be stored, accessed, and processed in a fixed format is called structured data.
2. Unstructured Data
Unlike structured data, this type of big data is not organized and sorted with instructions on how to use it. There is a general consensus that only 20% of all data is structured. So, if only 20% of all data is structured, does that mean the remaining 80% of data is unstructured? The answer to that question is yes.
Nearly everything you do with your computers and phones generates unstructured data. A typical example of unstructured data is a data source containing simple text files, images, and videos.
3. Semi-Structured Data
Semi-structured data is like a hybrid of structured and unstructured data, it toes the line between the two types of data. So, semi-structured data can contain both forms of data.
Characteristics of Big Data
Big data has four characteristics:
1. Volume
Just like the name ‘big data’, one of its primary characteristics is volume. Big data is primarily defined by its sheer size. The size of data plays an important role in determining the value out of data. Also, the volume of data is what ultimately determines if a data set is big data or not.
2. Variety
During earlier days, spreadsheets and databases were the only sources of data considered by most of the applications. Nowadays, data in the form of emails, photos, videos, monitoring devices, PDFs, audio, etc. are also considered in the data-processing applications. This variety of unstructured data poses certain issues for storage, mining, and analyzing data.
3. Velocity
Velocity here, just like in our Physics classes simply implies the speed with which data is generated. The speed with which the data is generated and processed shows real potential in the data – the greater the speed, the better.
4. Variability
This has to do with the inconsistency which is portrayed by the data sometimes. This inconsistency hinders the ability to handle and manage the data efficiently.
There are a couple of big data management technologies out there, here are a few:
- Cloudera Data Platform
- Google Cloud Dataproc
- Amazon EMR
- Microsoft Azure HDInsight
Conclusion
Now that you know what big data is all about, you will not be taken aback next time you hear your colleagues talking about it. Big data is something we can see all around us, especially in this day and age where everything is digital. Furthermore, the bigger the digital footprint we make, the bigger the size of data. That is big data analysis is so crucial. Most of the top apps that you use on a daily basis to help make your day better and easier all rely on big data analysis.
