  • Self Introduction

    • My name is Bluemo
      • I go by the ID @blu3mo and do various things
    • Surviving in New York
    • I like Scrapbox and The Mist of the World
      • Although recently I’ve been cheating on them with Obsidian
    • Among CS, I’m interested in fields with an ambiguous atmosphere
      • While there are risks, I think it would be interesting to combine humanities knowledge with engineering to create something interesting

  • What I’m going to talk about

    • First, I will talk about something I want to create recently (Proposal for Non-Turn-Based Communication with Voice)
    • Based on that, I will make a proposal for a more universal “world where computers generate reality”
      • It’s like half science fiction, but I hope you find it interesting
    • I didn’t have time to make slides, so please forgive me for using bullet points
    • If it’s interesting, I would like to write it down, so I would appreciate your feedback
      • What you found interesting, what you didn’t understand, etc.

  • Step 1. VR systems will become amazing

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

      • 

          - from [VRのための研究をしたい人へ　〜VR研究分野マップ〜｜yunoLv3｜note](https://note.com/yunolv3/n/n684f3bcb4e52) & VR学本
        

    • All of these will develop
      • Simulation systems
        • By using large-scale models, it becomes possible to generate complex information about reality
          • If you look at language (ChatGPT), images (StableDiffusion), etc., it becomes clear
        • The distinction between “real information” and “generated information” becomes difficult
      • Input systems and output systems
        • The interface between human perception and the computer’s “reality” will develop
        • Devices that provide information to perception, such as VR HMDs, headphones, and taste display, are evolving
    • These are recent buzzwords like “metaverse is amazing” and “AI is amazing,” and they are somewhat self-evident assumptions.

  • Step 2. As a result, “reality” becomes subjective

    • In the past, “real” reality and various “fictional” realities were distinguished
    • As a result of Step 1, it becomes difficult to distinguish between the experiences of “real” and “fictional,” and the two realities are treated in parallel.
      • Both are virtually real (Virtual Reality)
        • It’s like an experiential utilitarianism
        • Meaning of Virtual
    • In addition, “reality” becomes subjective (Phenomenological Reduction)
      • Phenomenologically, it is already subjective, but intersubjectivity (the state where multiple humans share the same perception of reality) becomes difficult to establish
    • 

  • Step 3. How people interact in this worldview / How reality is shared

    • A world where people can only choose between “completely sharing reality” or “not sharing reality at all” is problematic
      • It can be called a “dystopia”
      • Having more options is better
    • This is not a binary opposition between A and B, but there can be a spectrum between them (continuous)
      • It’s like a generalization of “Mixed Reality”

        • 

        • This assumes the dualism of “real reality” and “fictional reality” and considers this spectrum from the perspective of relative reality

          • It’s a loosely connected world where people can share their subjective realities to some extent
    • How can we achieve a gradual connection between the two?
      • We can consider the way reality is shared in terms of space and time
      • Sharing of space in a gradual manner- There are various examples that can be given here.

• For example, two people sharing a pizza, but it appears as a tomato pizza to person A and a seafood pizza to person B.

• For example, two people going out together, but person A thinks they are at an art museum and person B thinks they are in Harajuku.

• Sharing a loosely synchronized time ⭐️

• This is the main point I want to discuss.

• Here, the collection of subjective realities can be seen as a large-scale distributed system.

• When subjective realities are completely independent, they do not share time.

• When person A and person B interact, some kind of subjective timeline is assumed.

• Here, I want to consider not only complete synchronization, but also the sharing of loosely synchronized time.

• Being on the same timeline but at different timings, for example.

• Similar to the concept of Nico Nico Douga.

• To achieve this, I want to represent reality as a set of differences using data types like CRDT.

• If this can be done, the subjective realities of two people can be merged by setting a common timeline.

• In a rough sense, it is like a “reality that became git-like”.

• There are various mechanisms to deceive subjective sense of time, so various forms of loosely shared time can be considered using them.

• Elastic Synchronization, secretly changing the speed to eliminate time discrepancies, etc.

• MetaChron

• Control of Time Perception Using Virtual Space

• Interface that Coexists Real-Time and Slow Motion

• Concrete situations

• A voice communication environment where multiple things can be discussed in parallel while loosely sharing time.

• Proposal for Non-Turn-Based Communication with Voice

• 

• Could this be a solution to that?

• Lastly

• It would be interesting to discuss the specific implementation methods with the people here, I think.

• I want to know what is interesting or not interesting about this.

• I would like to hear your thoughts.

• I want to articulate the interesting parts in writing.

• Notes

• What was discussed afterwards.
