Virtual reality technology (VR) is mature enough to be widely used and long-lived, while another immersive technology, Mixed Reality (MR), is closer to functional applications.
When you stroll through the Dangjie Street in Sham Shui Po, Hong Kong, or wander around the crowded electronics shops in Shenzhen, you will find something about virtual reality. Every store sells VR glasses and even VR glasses cases. VR seems to be the next big thing in the tech world, but so far it's all low-end devices.
For now, VR is exactly the same as a smartphone; plug the smartphone into a big, stupid, head-mounted device like the Samsung Gear VR or Google (Cibo) Cardboard, then turn your head and enjoy YouTube. 360-degree video from Facebook, Facebook or various VR apps.
Specialized VR game headsets such as Oculus Rift, HTC Vive and PlayStaTIon VR will eventually prove their epoch-making significance in games, but for now, these devices are expensive and take a while to get into the general public.
At the same time, there are other immersive technologies that are emerging that may also affect the future of gaming, entertainment and even communications.

From holographic phones, to retina displays, to cinemaTIc reality and 3D projection, a new era of technology is on the horizon, and perhaps this area is more successful than VR.
The most widely publicized in MR may be Alibaba and Google's Magic Leap.
Open the Magic Leap website, and the on-the-spot video of a killer whale rushing out of the floor and splashing is so fascinating. This kind of video is as easy to overlay as the user interface in the real world. Some people comment that the technology of American company Magic Leap can replace mobile phones, laptops and other hardware, and finally make computing a hybrid of virtual and reality.
“The technology is able to place objects precisely and make them look right in your environment,†says creative technician Karl Woolley, who works with the London visual effects company Framestore in collaboration with Magic Leap.

Magic Leap uses dynamic digiTIsed lightfield signal technology, which breaks through the limitations of the touchscreen user interface and creates a virtual interface controlled by gestures and voice. Although the details of how it works are rarely published, some believe that the company's market capitalization has reached $3.7 billion.
“Magic Leap has a huge amount of money to develop retina display technology... Maybe we will have real-life video games, and Magic Leap can bring us all kinds of surprises,†said Principal Analyst, information and analysis company HIS. Researcher Paul Gray said.
Despite Magic Leap's heavy software and light hardware, the company's fascinating "film-realistic" vision requires the use of a head-mounted virtual retina display to successfully overlay 3D graphics into the real world.
This form of augmented reality is difficult to achieve in realizing such a large real holographic image.
“Technically, the concept of holographic images is physically impossible because you need to stop the light somewhere in space,†explains Woolley, the light is only reflected when something touches the human eye. Color and brightness are recognized.
Microsoft's HoloLens
This did not prevent humans from trying to develop holographic phones, but early prototypes used a glass pyramid on the screen to reflect light. This solution is not ideal.
"It looks like the object will rotate in the air, but it's not. The light is just projected and reflected," Woolley explained the principle of this miniature palm holographic image.
Researchers at the Human Media Lab at Queen's University in Ontario, Canada, have developed a technology called HoloFlex that produces small holographic images without pyramids or holographic glass, but with low resolution.
The London company Virtual Presence has designed another solution that puts the phone in a small box called Virtual Mobile, using small projection technology to project light onto nearly invisible material.
After the viewer downloads the holographic content on the phone and puts the phone into the box, the hologram will appear in front of you. This is a smart solution that Virtual Presence has promoted as a new advertising platform that can even be used for religious activities and political campaigns, but who will put the phone in a box? The problem that plagues virtual reality also occurs in mobile holographic solutions.

Another groundbreaking technology, dynamic holography, almost completely eliminates hardware, but because it is too complex, the performance of smartphones is not enough.
At the same time, holography is destined to make computing a hybrid experience, making the desktop a virtual touchscreen that allows a wide variety of digital elements to be covered in the real world.
In a recent demonstration, Microsoft let the audience see that through two Hololens headsets and a tablet with a camera, the plumber can not only advise the customer, but also draw a virtual one at the joint that needs to be fastened. Circle.
Holloxica's holographic display in Scotland converts computer 3D images into digital holographic images. Users can touch the icons in the space, interact with them, and draw patterns with their fingers in midair.
Mitsubishi's holographic display can project 56-inch images in mid-air, and the company hopes to release it before the 2020 Tokyo Olympics.
"The key difference between VR and MR is that VR allows you to enter the world of Game of Thrones," Woolley said. "And MR allows you to see the characters in Game of Thrones in your existing environment."
Virtual reality may now attract everyone's attention, but in this increasingly personal digital age, mixed reality may be the most promising form of interaction. (Autumn participated in the compilation)
