VR tabloid line salon guest Xiaohuaxiu VR marketing director Li Shihui speech dried goods - VR live alone rely on technology, the anchor must also be trained to create a sense of depth.
"The VR tabloid series Salon V: The exploration of different manifestations of VR video" was successfully held. At the meeting, Xiaohuaxiu VR marketing director Li Shihui made a comparison between traditional live broadcast and VR live broadcast, and conducted an in-depth analysis of the characteristics of VR live broadcast.

Do users really need 360-degree broadcast?
The greatest advantage of VR live streaming is the strong sense of immersion that allows viewers and anchors
"0 distance" is its biggest bright spot. But blindly pursuing immersion rather than considering the nature of live broadcasting, Li Shihui thinks that this is often not worth the candle.

“For users, the purpose of entering the room is very clear. It is to interact with the anchor. Their focus is on the anchor.†Li Shihui added that if a 360-degree live broadcasting solution is used, it means that the user will be the first one after entering the room. The task is to find where the anchor is, and it is necessary to continuously adjust the posture as the anchor moves. This does not meet the normal people's perception of the live broadcast.
Therefore, Li Shihui believes that using a 180-degree content broadcast scene is sufficient. In addition, this can also reduce the vertigo phenomenon caused by the current erroneous VR devices, and the 180-degree transmission requirements also greatly reduce the live broadcast software configuration requirements for VR models.

According to the tabloid monarch, the immersive feeling of VR live broadcasting is not entirely from the display of the environment. Whether there is depth of field will become an important factor in measuring the strength of immersion. At present, the 3D panoramic camera used by Xiaohuaxiu VR can shoot the binocular 3D display in real time, which greatly enhances the authenticity of VR live broadcast.
The anchor should learn to use the depth of field
Currently, 3D technology plus VR's panoramic imaging method can make live broadcasts immersive. However, Li Shihui believes that technical compliance is only the first step, and a more important step is to teach the anchor to match the technical advantages to achieve the best immersive VR live streaming effect.

Here, Li Shihui explained in detail the requirements of VR live broadcasting on the anchor and environment layout through two contrast maps of traditional live broadcast and VR live broadcast.
As shown in the figure, the traditional live broadcast can generally only see the upper part of the anchor, and it is difficult to see the whole body in dancing. VR broadcast requires the host to try to enter the whole country as far as possible, and to do more actions that can give the user a strong three-dimensional effect in such interactive stages as dancing and singing. Second, the correct placement and color matching of room items will enhance the user's experience of immersion.
When the tabloid monarch actually experienced Xiao Huaxiu's VR live APP, he really felt a strong sense of depth due to the anchor's action and room decoration. But for every first-time VR broadcaster to master such skills, Li Shihui said that special training is still required, which to a certain extent reduces the popularity of VR live broadcasting.
What is the future of VR broadcast?
Finally, Li Shihui simply shared a few new features that VR Live can add in the future with the current research and development project of Xiaohuaxiu VR:
(From top to bottom: technical overlay of object overlay, MR and face detection)
Green Screen Keys - Using Green Screen technology to achieve the integration of anchor and virtual backgrounds to achieve MR live broadcasting;
Object overlay - real-time object overlay through face detection, can be applied to the VR live filter function;
Face detection - monitoring through depth recognition, feature information can be transmitted simultaneously with the video stream;
Virtual anchor - to do a virtual image through motion capture, which is more suitable for people with different looks, for secondary enthusiasts is his food;
At present, the realization of these technologies faces a common problem, namely how to enable these functions to recognize and automatically generate 3D models to achieve the same immersive effects as live streaming. In this regard, Li Shihui also said that this is a technical problem that Xiaohuaxiu VR has done its best to break through.
to sum up
In general, VR live broadcast, as a new branch of traditional live broadcast and emerging technologies, will have more promising development prospects.
