• Oh, this looks really interesting (blu3mo)(blu3mo)

• Is this the same lab as RealityCheck: Blending Virtual Environments with Situated Physical Reality?

• SIPLAB

• The basic concept is in the lineage of Remixed Reality: Manipulating Space and Time in Augmented Reality.

  • It’s interesting that they record what happened in a causality graph structure, enabling playback.

What is it?

• From asynchronous messages to an asynchronous reality.
  • Nice phrase.
• The contributions of our work are two-fold. First, we present Asynchronous Reality as a general concept. Second, we implemented a system called AsyncReality as an instance of our concept.
  • I want to write a paper like this (blu3mo)(blu3mo)(blu3mo)
• There is No Need to Always Be in Sync

• It feels like a summary of the previous research on 2.1.2, Virtual Time.

  • The following might not be relevant. They do a simple Pseudo-Synchronization, but that’s not the key.

    • Oh, this is interesting (blu3mo)(blu3mo)
    • I was curious about how to model causality.
    • It seems to discuss in the context of a 2D editor.
  • This paper aims to create a reality that follows causal relationships, even though it is purely asynchronous.
    • I see? (blu3mo)

What are the key techniques or methods?

• The processing of resynchronizing from an asynchronous state is the key technique.
  • Resynchronizing from an Asynchronous State
  • It is implemented assuming a situation called focus mode, but it is a technology that can be used more generally for resynchronizing from async to sync cases.
    • Like Elastic Synchronization
  • Very good (blu3mo)(blu3mo)(blu3mo)(blu3mo)(blu3mo)
• Let’s understand causality graphs (blu3mo)
• Non-uniformity of Spacetime is also interesting.

How did they validate its effectiveness? Are there any discussions? What papers should I read next?

• RealityCheck: Blending Virtual Environments with Situated Physical Reality
• Technologies that generate real-time 3D space from RGB-D cameras

They mention the Space Groupware Matrix.
