Like many people expected, this year's MWC Shanghai show did not have much surprise. The VR field is still slow, hardware iteration speeds slow, yet the content has once again raise everyone's attention.
With the advent of Apple ARKit and Google ARCore, mobile AR has been making rapid progress this year. Both hardware vendors and content providers are following suit. In the following we will review the MWC Shanghai show this year on VR/AR and related issues.
This year, MWC Shanghai has opened 7 exhibition halls for N1-N5, W4, and W5. Among them, N1-N4 focuses on industrial fields. For example, IoT, Smart City, and robots are basically all around 5G, and AR/ Exhibition areas such as VR/MR are concentrated in Hall W5.
HTC Vive showcases a lot Apps and new features of Vive Focus
A large part of the W5 zone was packaged by the HTC Vive. This HTC Vive showcased almost all the products including Vive Pro, Vive Focus and U12+ mobile phones. Last month, HTC released the Vive Focus 2.0 system, bringing new waves. Functions, such as linkage with mobile phones, mobile phones as 6DoF accessories, look-around modes, etc., several of which are not open.
HTC Vive displayed a large number of application cases. For example, the Vive Pro baseball experience announced at the HTC New Ecology Conference last time, Vive Focus's mobile phone linkage experience, and of course, some will not be introduced before. Here we take a look at the new Applications.
At the MWCS Shanghai show today, HTC made the first public demonstration of a mobile screen projected to VR head-up (Vive Focus), such as seeing Weibo, Wechat and so on in VR. And of course it still uses 2D screen, but you can adjust the position and size of the window, but now and not support the handle to replace the finger to slide the screen content. HTC said it will support this feature soon. This function is still based on Miracast. Although it is not a new technology, the game mode that is linked with the mobile phone is constantly refreshing.
Thanks to the ability of Vive Focus to support 6DoF tracking, the mobile space game "Floating Island" is also a focus. This is a fun game. It should follow its fixed trajectory. There are various obstacles (such as broken bricks on the ground, laser bars in the air, etc.). The game is very interesting, easy style, suitable for all ages.
In addition, a large space game "Project Ghost" based on Vive Pro is also shown this time. This game is made by ifgames and is a double battle mode. During the experience process, the left hand wears VR gloves, and both lower legs also have a Vive Tracker. The right hand is a handle. In the game, the opponent can be killed, but it does not score. The points are completed by grabbing the baby in the game map. The overall trial down feels good, rich interaction and interesting.
Vivo Brings ToF 3D Super Sensing Technology
Vivo has long been out of the troubles of the cottage through years of technology accumulation. For example, the pop-up camera design in the recently released NEX mobile phone was a prototype launched in Spain's MWC earlier this year. Domestic manufacturers are increasingly focusing on the design experience. This release of ToF 3D super-sensing technology is to prepare for future applications such as AR.
At the press conference, Vivo talked about the difference between ToF 3D technology and structured light. Vivo product manager Wang Zhaofeng spoke at the scene that ToF is 10 times more efficient than the latter in terms of effective depth information, and the working distance is 3 times that of the latter. Relying on TOF 3D super-sensing technology, mobile phones can realize such functions as face recognition, gesture and body recognition, and 3D photographing.
The Vivo conference also showed some prototypes based on ToF, which provided modeling of faces and heads, and supported further adjustments. Vivo's ToF solution is still ideally suited for control of battery life and heat generation, and these technologies may be applied to the front-end and back-end of mobile phones, front-end for face modeling, and back-end for AR applications such as long-distance ranging. Next step is to wait for Vivo's new device.
Lochn Optic, energy produced AR optical guide
According to the experience of reporters at the scene, it is not only a relatively advanced parameter, but also a very real practical effect. It can be regarded as the leading optical manufacturer in the current domestic scheme.
In addition, Lochn Optic also displayed a hologram glass. It will display different images depending on the viewing angle. The actual viewing effect is ideal (there are reflections). But the premise needs an external light source to shine, otherwise the effect may not be ideal. It is understood that this's done through a special hologram glass and is completed through special printing.
Lenovo DaystAR, full-featured AR all-in-one
Before long Lenovo released the DaystAR All-in-One, a fully functional AR device. Yes, it is an integrated all-in-one, similar to HoloLens.
DaystAR uses a free-standing surface prism optics solution with a resolution of 720p and a field of view of 43 degrees. It also supports SLAM, gesture recognition, and voice interaction. The weight of the entire device is 470g.
As expected, DaystAR wearing experience was slightly worse, mainly due to its heavy weight. According to the staff, the current DaystAR has not yet been sold, and the price may be within 2,300 dollars. At the same time, it also revealed that a split version is currently under development. The optics and functions are consistent with this version, mainly to solve the wear experience problem.
DaystAR project is affiliated to the Lenovo Shanghai Research Institute. The project was born for many years, and most of the SLAM, gestures, and voice technologies are self-developed. Meanwhile, a remote collaborative application case is also demonstrated on the spot. The back end can be passed through devices such as tablet PC, providing guidance on AR equipment.
Qualcomm: Bringing a Frontal Face Unlocking Solution for Mobile Phones
Qualcomm is a leader in the field of mobile chips, and it is doing great jobs in other fields such as VR. Now with the recent increase in 3D structured light in smart phones or other similar face unlocking programs, Qualcomm is also participating.
The live demonstration of a circular mobile phone has two sensors on the top, an infrared transmitter on the top, and an infrared capture camera on the bottom. The overall solution is not structured light, similar to the infrared face unlocking program in Xiaomi 8. Staff said that the program is still in its infancy, and this solution is not limited to the chip. They will provide an overall hardware and software solution.
China Telecom: Bringing 5G VR Video, 5G Cloud VR Game, 5G 8K Video Demonstration
When it comes to 5G, there are naturally three major operators. At the zone of China Telecom, we found a demonstration of 5G cloud VR games, 5G VR video, and 5G 8K video in one corner.
The live demonstration of 5G cloud VR video is done through an edge cloud server. The device is a Pico Neo version with dual 6DoF controllers. Through its demonstration of game Beat Saber, the overall delay effect is ideal and there is no Caton. The staff introduced that this was done by Nokia and China Telecom, with a delay of less than 20ms.
In the 5G VR video, the real-time image is also demonstrated. The panoramic camera was set up on the top of a district in Pudong, Shanghai.
China Unicom: Stereo Mixed Reality Solution
China Unicom demonstrated that its station is a three-dimensional mixed reality solution. One of them is a 3D video transmission scheme based on its own IPTV set-top box, and the other is a multi-interaction scene screen through eyeball tracking, gesture recognition and the like.
It is understood that China Unicom is planning to bring this type of interaction based on eye tracking and gesture tracking into the home through the set-top box or other customized services. In the future, these interactive scenarios may be directly applied to the cloud without downloading.
Senso: Wear gloves that support Steam VR
This is a company from California, USA, which has wear gloves and wear vests and tracking devices. It wears 7 IMUs and 5 vibrating electronics built into its glove, with a battery life of approximately 10 hours, a built-in vest containing 15 IMU sensors and 15 vibration electronics, both of which support Steam VR base stations.
It is understood that Senso's VR gloves and two-handed suits are priced at US$600 and are currently mainly used in industrial and other B-end related fields.
