📕 What is “Virtual Time”?

  • Analogy: Virtual Reality for Time, not Space
    • 🗺 Physical Space vs Virtual Space
      • imageimage
    • 🕑 Physical Time vs Virtual Time
      • (relativizing physical time)
  • Definition:
    • Definition of Virtual Reality:
      • An experience that seems different from reality on the surface, but has the same effect as reality (Hirose, 2019)

    • Then, the definition of Virtual Time:
      • An experience of “time” that seems different from real time on the surface, but has the same effect as time.

🛠 How is it possible?

  • In other words, how can we recreate the virtual effect of time?
  • Virtual Space:
    • Perception of space: Internal Sense of Space + External Stimuli
      • External Stimuli: Sight, Sound, Haptics, etc.
    • The experience of moving in virtual space can be created through artificial stimuli.
    • Virtual Space allows for more freedom:
      • Flying, Warping, Non-Euclidean space, etc.
  • Virtual Time:
    • Perception of time: Internal Sense + External Stimuli
      • External Stimuli: Sense of synchronization with other changing actors (clocks, people, etc.)
        • (hypothesis)
    • The experience of moving in virtual time can be created through artificial stimuli.
    • Virtual Time allows for more freedom:
      • Speed manipulation, Warping, Looping, etc.

🤔 What I want to do with this concept

  • I don’t want to force virtual reality/time, but rather provide an alternative choice of reality/time.

⚗️ Applications

- Interactive lecture video streaming platform
    - Student-generated content overlaid on lecture video
- Goal: Combine the benefits of real-time and on-demand lectures
    - Benefits of real-time lectures: Interactive communication between students
    - Benefits of on-demand lectures: Control of time
- Method: Virtual time through artificial stimuli
    - Pseudo Sync (擬似同期)
        - Gives a pseudo sense of synchronization with other students interacting in lectures
    - Elastic Sync (弾性同期)
        - Secretly control playback speed within the range of 0.9~1.2x
        - Synchronize unsynchronized students

- Issue with current voice communication: Only one thread available
    - Difficult to have branching discussions
- Applying ==Elastic Sync == to create multithreaded voice communication, where participants eventually receive content from every thread
  • 🔬What to research?
    • Some ideas:
      • Human-Computer Interaction, Computer Mediated Communication
      • Applying time-compression algorithms and knowledge from cognitive science
      • But I want to focus on engineering and applied science, not basic science
