History of Virtual and Augmented Reality

Virtual and Augmented Reality have come a long way since the first use of a head-mounted display in 1968. Today, these technologies are being used to create immersive experiences in fields such as gaming, education, and healthcare.

In this article, we’ll explore the history of VR and AR, the current and future uses of the technology, and its impact on different industries and everyday life.

Early VR and AR development

In the 1950s and 60s, the first prototypes and experiments with virtual reality started to appear. Scientists at various universities and research labs began experimenting with primitive head mounted displays (HMDs) to simulate the experience of immersion in a 3D environment. As technology progressed, HMDs became more sophisticated and affordable, and saw their first commercial use in training military pilots in the 1980s.

In parallel with developments in VR, researchers were also exploring similar ideas with AR. In 1968, pioneering computer scientist Ivan Sutherland created a prototype optical see-through display that superimposed primitive 3D graphics over real-world objects in a room. Other people like Tom Caudell and David Mizell later coined the term “augmented reality” after their work on creating systems that would help workers efficiently assemble airplanes.

By 1992, AR had applications beyond industrial use as British engineer Louis Rosenberg showcased the use of it for virtual television set design. It wasn’t until 2018 that AR feasibly gained mainstream traction with Apple’s iOS11 launch of ARKit for its mobile devices.

Today, virtual reality is still mostly focused on gaming experiences but has applications for education, mental health therapy (including diagnosing phobias), sports training, rehabilitation therapy (for stroke victims), automation tutorials, shopping experiences along with many lesser known uses like telemedicine which make use of immersive remote environments in order to access medical care anytime anywhere!

Augmented reality is being used across different areas including:

  • Architecture where designers are able to bring their blueprints to life while before they have been sketched or made out of cardboard models;
  • Automotive design exploring more efficient ways for clients to customize their cars;
  • Medical science to poke around organs during surgery or help diagnose complex issues inside patients;
  • Military allowing soldiers to carry less gear on them by projecting visuals through lenses onto a solider’s eye gear;
  • Retail creating an interactive online shopping experience way beyond what online stores can currently offer – such as getting instant feedback right trying out clothes / appliances right away!

Recent advances in VR and AR technology

The past few years have seen rapid advances in virtual and augmented reality technology. Improvements in computer processing power, digital memory storage, sensors, and displays have enabled these technologies to deliver increasingly realistic experiences.

Virtual reality devices have become smaller and more affordable since 2018, when standalone VR headsets such as the Oculus Quest hit the market. This portability has enabled VR applications for niche use cases such as virtual field trips, training simulations, team planning sessions (also known as whiteboarding), sports viewing experiences and immersive videogames.

Augmented reality technology has also made major strides with the rise of Apple’s ARKit (Apple’s software development framework for building augmented reality apps) and Google’s ARCore (Google’s software development kit for mobile devices aimed at developing augmented reality apps). As these tools make it easier to create iPhone-compatible AR apps using existing content developers are now beginning to explore novel applications of this technology in fields like education, gaming, training simulations and healthcare.

These improvements mean that users can now experience a range of immersive environments –whether they are designed virtually or augmented upon a real life environment– with higher levels of realism. Virtual and augmented reality is changing how we interact with data through visual tools that allow us to engage in immersive activities that was once impossible before their invention.

VR is the most immersive type of gaming technology available, putting users “inside” their game world by simulating all five senses in a realistic surrounding. As players wear a VR headset, they can turn their head in any direction to look closer at objects within the simulated environment. Many incredible gaming experiences are now able to be created with VR such as shooter games, fighting games and horror themed games.

Augmented reality (AR) gaming combines real-world objects with virtual ones displayed on top using advanced graphics technology. While still maintaining a physical connection with the real world around them, AR gamers are able to play through games while interacting with digital elements that appear in one’s environment instead of just being limited to playing on artificial environments such as PC or console games. Popular AR Games such as Pokemon Go and Harry Potter Wizards Unite are just examples of what can be created with this exciting technology.


The healthcare sector is one of the promising areas leveraging virtual and augmented reality technology. It is revolutionizing the way healthcare professionals are training, diagnose and treat patients.

VR in Healthcare: VR has been applied in medical fields in three distinct ways:

  • Education and Training – The goal of using VR in medical education is to improve learning by creating a virtual environment, where students can interact with 3D models or stimuli that imagine realistic clinical scenarios. This enables medical students to practice their skills without putting the patient’s health at risk.
  • Treatment – VR offers therapeutic options such as cognitive therapy, exposure therapy and pain management that helps patients cope with anxiety, depression, and chronic pain issues.
  • Surgery Preparation – VR can provide surgeons with a 3D view of their patient’s anatomy for accurate preoperative planning before performing surgery reducing time spent on surgical procedures.

AR in Healthcare: AR also plays an important role bringing additional advantages such as being able to present visual information from instruments, CT scans or X-rays integrated into the patient’s natural environment instead of just reading from a 2D image or abstract diagnostic system display. By utilizing AR clinicians are able to visualize actual injuries or diagnose medical conditions faster and more accurately while simultaneously providing better healthcare outcomes for their patients. In addition, AR devices enable clinicians provide remote diagnosis without having to be physically present at the site thus offering an opportunity for cost savings while providing early care when needed most.

Immersive experiences

Immersive experiences are those that completely envelop users in a virtual world, making them feel as if they are part of the environment itself. This type of experience is possible through virtual reality (VR) and augmented reality (AR) technologies.

Virtual reality can take users to entire, computer-generated worlds and allow them to interact with them and other players within the same environment. It’s typically used for gaming or entertainment purposes, but it can also be used for recreation or athletic training instruction.

Augmented reality devices offer similar capabilities, but slightly differently from virtual reality—overlaying digital data onto a live image of the real world, thus creating a hybrid immersive experience combining elements from both environments. This technology has been used in many fields such as education, gaming, healthcare and more recently, retail shopping for customers to try clothes on virtually before purchase.

Both VR and AR technologies have greatly enhanced user experiences by providing lifelike digital visualizations which can be manipulated interactively using motion sensors or voice commands. As these technologies continue to evolve over time, they will provide even more engaging ways for users to experience their desired realities without ever leaving their homes or offices.

Improved access to information

Virtual and Augmented Reality (AR/VR) technologies can provide improved access to information and improve the way people learn. By utilizing these technologies, students and teachers are able to access a vast world of knowledge without leaving their classrooms. For example, medical professionals are able to use AR/VR to view 3D scans of patient anatomy or use simulations to practice in scenarios that would otherwise be impossible.

In addition, AR/VR has revolutionized the gaming sector, allowing for more realistic and immersive experiences for gamers. It has also captured the interest of medical researchers who are looking for ways to make surgery less invasive by conducting simulations in a virtual environment before performing an operation on a patient. Further applications include using these technologies in museums and other educational centers so visitors can get more hands-on interactive experiences with artifacts or historical sites.

In short, Virtual and Augmented Reality offers individuals many opportunities to experience information in new ways. By leveraging this technology, students and educators alike can get access to invaluable resources while also greatly increasing their learning capabilities when compared with traditional learning methods.

Challenges of Virtual and Augmented Reality

Virtual and Augmented Reality (VR/AR) have revolutionized the way we experience and learn about the world. As these technologies have advanced, they have been used for applications ranging from gaming to education, to healthcare. However, these technologies present their own unique set of challenges that have to be addressed.

Let’s take a closer look at these challenges:


Cost is a major challenge associated with the adoption and implementation of virtual and augmented reality. VR/AR technology requires cutting-edge hardware, which can be expensive. On top of the initial expense, continued maintenance and updates can also add up over time.

For example, headsets, motion controllers, motion tracking systems, haptic feedback mechanisms, etc. are all necessary elements that must be purchased in order to get a complete and immersive experience out of either system. Thankfully, the cost to access this technology is declining as more affordable options enter the market.

In addition to hardware costs associated with VR/AR experiences, there are certain licensing fees that may have to be paid for certain applications or software used in conjunction with either platform. Licensing fees may be compounded when hardware requirements also come into play; for example if you’re creating an engagement program for mobile phones using augmented reality technology then you may require additional licenses for each device being used during the event.

Furthermore, implementation costs can add up if companies need to hire personnel or agencies specifically dedicated towards development and maintenance of interactive experiences using virtual or augmented reality platforms like creating 360-degree videos or developing custom applications from scratch. Depending on their size and complexity these development costs can range from hundreds to thousands of dollars in some extreme cases even reaching into six figures.

Limited hardware

One of the biggest challenges to adoption and implementation of virtual and augmented reality technologies is the hardware required for use.

Privacy concerns

Privacy concerns are among the most worrisome considerations when evaluating virtual and augmented reality technologies. Since these technologies rely on gathering large amounts of data, they present significant risks to users’ privacy, including collection and processing of both explicit and implicit user data, unauthorized sharing or selling of that data to third parties, as well as risks of cyber-attacks through malicious programs such as malware.

In order to protect users’ privacy, developers of various applications that use virtual and augmented reality need to take steps such as:

  • Providing clear enough instructions for users about the usage of the application.
  • Giving them details about the kinds of data collected by it.
  • Obtain their consent prior to collecting any personal information from them.
  • Protecting sensitive user data from unauthorised access by third parties.

As users become more technologically savvy with respect to their technological rights and needs, it is even more important for companies building these platforms to create tight security protocols with respect to user data storage and access.

Furthermore, web browsers playing an important role in protecting consumer privacy should partner with developers in order to help ensure that private information isn’t sent out automatically during certain interactions. Finally, distributors should also ensure that all pre-installed applications adhere strictly to consumer privacy laws established in various international jurisdictions.
