  • Self-Introduction

    • I go by the name Bluemo
      • Engaging in various activities under the ID @blu3mo
    • Surviving in New York
    • Fond of Scrapbox and The Mist of the World
      • Though recently, I’ve been cheating on them with Obsidian
    • Within the realm of CS, I am interested in ambiguous fields
      • While acknowledging the risks, I believe combining humanities knowledge with engineering can lead to interesting outcomes

  • Discussion Topics

    • Firstly, I will talk about something I want to create recently (Proposal for Non-Turn-Based Communication with Voice)
    • Then, I will propose a more universal idea of “Wouldn’t it be nice if computers generating reality became like this”
      • It’s somewhat like a sci-fi concept, but I hope you find it intriguing
    • Apologies for not having time to create slides, so please bear with the bulleted notes
    • If the content is engaging, I would like to document it, so I’m looking forward to hearing your feedback
      • Whether you found it interesting, had trouble understanding some parts, etc.

  • Step 1. Advancement of VR Systems

    • As a representation of VR systems, there is a diagram like this

    • All aspects of this are evolving
      • Simulation systems
        • Capable of generating complex real-world information through large-scale models
          • If you look at language (ChatGPT), images (StableDiffusion), it becomes apparent
        • Distinguishing between “real information” and “generated information” becomes challenging
      • Input systems, output systems
        • Human perception and the interface of the computer’s “reality” are advancing
        • Devices providing information to perception, such as VR HMDs, headphones, taste display, are evolving
    • These discussions are currently revolving around buzzwords like “Metaverse is amazing” and “AI is amazing,” to some extent, considered obvious assumptions

  • Step 2. Consequently, Reality Becomes Subjective

    • Traditionally, a distinction was made between the “real” reality and various “fictional” realities
    • As a result of Step 1, the distinction between experiences of “real” and “fictional” realities becomes blurred, and both realities are treated in parallel.
      • Both are virtually/effectively real (= Virtual Reality)
        • A kind of experiential utilitarianism
        • Meaning of Virtual
    • Subsequently, “reality” becomes subjective (Phenomenological Reduction)
      • Phenomenologically, it was subjective from the start, but intersubjectivity (the state where multiple humans share the same perception of reality) becomes harder to establish
    • 

  • Step 3. How People Interact in This Perspective / Ways of Sharing Reality

    • In a world where people can only choose between “completely sharing reality” or “not sharing reality at all,” it feels awkward
      • It can be described as somewhat dystopian
      • More choices are better
    • Rather than a binary opposition of A or B, I want to suggest the existence of a Spectrum between them (continuous)
      • A concept generalized from so-called “Mixed Reality”

        • 

        • This assumes a Spectrum based on the dichotomy of “real reality” and “fictional reality”

        • Considering relative perspectives, this Spectrum can be envisioned between each person’s subjective realities

          • The extent to which one shares reality with others creates a gentle world
    • How can we realize a gentle connection between these two extremes?
      • Considering the sharing of reality in terms of space and time
      • Sharing of reality in a gentle space- This is a place where various examples can be given.

• For instance, imagine two people sharing a pizza: Person A sees a tomato pizza, while Person B sees a seafood pizza.

• Another example could be two people going out together: Person A thinks they are at an art museum, while Person B believes they are in Harajuku.

• Sharing a relaxed time together ⭐️

  • This is the main point of discussion.
  • Here, the gathering of subjective realities can be seen as a large-scale distributed system.
    • When subjective realities are completely independent, they do not share time.
      • A’s time and B’s time are completely unrelated.
    • When A and B interact, some form of shared subjective timeline is assumed.
      • Here, not just perfect synchronization, but also considering sharing a relaxed time is desired.
      • Being on the same timeline but at different timings, like the concept of NicoNico Douga.
      • To achieve this, expressing reality as a set of differences is desired.
        • Want to represent “reality” with a data type like CRDT.
        • If this can be done, by setting a common timeline, the subjective realities of two people can be merged.
          • Roughly speaking, a “world that has become git-like reality.”
    • There are various mechanisms to deceive subjective time perception, which can lead to various forms of sharing relaxed time.
      • Elastic Synchronization, secretly adjusting speeds to eliminate time discrepancies.
      • MetaChron
      • Control of Time Perception Using Virtual Space
      • Interface that Coexists Real-Time and Slow Motion
  • Specific situations
    • A voice communication environment where multiple things can be discussed in parallel while sharing time loosely.
      • Proposal for Non-Turn-Based Communication with Voice
    • 
      • Could this be the solution to this?

• In conclusion

  • Discussing the specific implementation of this, it would be interesting if the people here discussed it.
    • Want to talk about it.
  • Want to know what’s interesting/not interesting about it.
    • Want feedback.
    • Want to articulate the interesting parts in writing.

• Notes

  • Things discussed later.
