VRSionUp!8: Meetup in Online WebVR events

About me

Hi, my name is Liudmila Bredikhina. I’m a virtual intern at GREE VR Studio Lab, and I’m a Master’s Degree student at the Geneva University. I’m currently majoring in Asian Studies, and I research Japanese Virtual Beings, such as VTubers.

Introduction

VRSionUp!8 was held on September 8th, 2020, from 7 pm — 9 pm JST. The title of this eight edition was “WebVR Online Event Development.” There is a rising demand for the technological development of online events during COVID-19. During this VRSionUp!, various researchers shared techniques for conducting such online events using WebVR. Simultaneously, there was a report on the GREE VR Studio Laboratory’s research and development, such as SIGGRAPH 2020 and VTech Challenge 2020. VRSionUp!8 took place in Mozilla Hubs, and the audience could watch the live stream on YouTube. Once the event was over, a URL of the Hubs Room was sent to the audience, and they could join the speakers for a casual meet-up in Hubs.

Live demonstration of Vibe Share technology with me and Yusuke Yamazaki

Me and Yusuke Yamazaki demonstrated VibeShare technology. We began with my real face: the audience could send “virtual clapping” by scanning a QR code and shaking their phones, which resulted in the HapBeat vibrating. I then demonstrated the vibrating HapBeat by holding the device with my finger. The whole process was filmed with my real face. Then I moved to Virtual Cast and appeared in front of the audience as my virtual self. I played a game developed by Yusuke: to shoot the enemy, the audience had to send me “kawaii,” and “moe” comments to reload my gun. At some point, I had an invisible enemy that the audience could see, but not me. So, the audience had to engage in “virtual clapping” to activate my HapBeat and feel (with vibrations) the enemy’s location.

The organizers then took everyone around the virtual venue. The background photo was virtual Roppongi Hillswith the Tokyo Tower. Such a change of view and “walk-around” can only be possible with a virtual environment that Hubs provided with.

“Hubs De Mokumoku Blender Event Report and Acoustic Design” by Toya Sakaguchi

Toya Sakaguchi presented the acoustic design technique in Hubs scheduled to be announced at the VTech Challenge 2020 and the Japan VR Society Conference. “Mokumoku kai”(もくもく会) is a sort of hack-a-thon events that focus on coding and creation. Toya talked about his internship and the audio environment design in Hubs. The goal of the audio experiment was to understand the different types of audio perceptions in Hubs. You can find more detail here in Japanese.

In our article about KIDS WORKSHOP for Web3D (https://2020.web3dconference.org/), we talk more about the Hubs’ spatial audio system. The conference will take place sometime between the 9th and 13th of November.

Conclusion

This 8th edition of VRSionUp! further discussed various aspects of online events developments. The spatial audio technique, virtual environment, and workshop organization were discussed. This event was perfect for students, as they could share their latest projects and creations. Social meetup creates a space where everyone can discuss different subjects and network.

While this event is not directly related to my research, it was interesting to see how individuals can gather in a virtual space and interact. Moreover, this a series of workshop events leading to VTechChallenge 2020, which will be held in Mozilla Hubs.
