Immersive technologies include virtual reality, augmented reality, and mixed reality

Virtual and augmented realities are paving the way for a more immersive future

Tech companies like Apple, Meta, and Microsoft invest heavily in immersive technologies such as virtual, augmented, and mixed reality. While VR transports users to a fully digital space and AR adds digital elements to the real world, mixed reality allows interaction with both at once.

What is mixed reality?

Mixed reality is a technology that blends the physical and digital worlds, allowing virtual and real objects to coexist and interact in real-time. It combines elements of both virtual reality and augmented reality, enabling users to perceive and manipulate digital content as if it were part of their physical environment.

Immersive technologies are increasingly being used in medicine, retail, and education

More accessible devices and user-friendly tools have increased the adoption of these technologies, which provide interactive, 3D environments that facilitate natural human learning. In 2018, Walmart purchased 17,000 VR headsets to train over a million employees in areas such as customer service and Black Friday preparation.

The technology enables presenters to step into virtual environments that incorporate 3D models and real-time data, providing more engaging and interactive forecasting. They have also facilitated the development of educational segments where meteorologists use virtual models to explain complex weather phenomena.

Mixed reality devices can turn digital information into 3D experiences

Described as "wearing a theme park on your face," devices like Microsoft's HoloLens project images into users' eyes so that their brains believe virtual objects are actually there. The bulkiness and physical limitations of existing headsets are expected to lessen over time, mimicking the evolution of early headphones.

Integrating mixed reality has made art galleries and museums more interactive and accessible

The technology bridges the gap between history and modernity in such spaces by attracting new, younger audiences while preserving cultural heritage through risk-free immersion. Mixed reality experiences, such as visiting reconstructed historical scenes or seeing virtual twins of lost paintings, can be programmed with software features for visitors with disabilities.

The virtual reality era has finally arrived

The smartphone era has driven a large share of the consumer electronics market for almost 20 years now. But what comes next? Dominant computing platforms come and go over time, and there’s reason to believe that mixed reality devices like headsets and glasses might be the form factor that eventually replaces smartphones. This article presents a snapshot of where we are right now in the VR era, and what the future holds.
