📕 What is "Virtual Time"?
Analogy: Virtual Reality for Time, not Space
🗺 Physical Space vs Virtual Space

🕑 Physical Time vs Virtual Time
(relativizing physical time)
Definition:
Def. of Virtual Reality:
Experience that superfically seems different from reality, but virtually has the same effect as reality (Hirose, 2019)
Then, def. of Virtual Time:
Experience of "time" that superfically seems different from real time, but virtually has the same effect as time.
🛠 How is it possible?
i.e. How could we reconstruct the virtual effect of time?
Virtual Space:
Perception of space: Internal Sense of Space + External Stimulis
External Stimulis: Sight, Sound, Haptics, etc
Experience to move in virtual space can be constructed by artificial stimulis
Virtual Space has more freedom
Fly, Warp, Non-euclidian space, etc
Virtual Time:
Perception of time: Internal Sense + External Stimulis
External Stimulis: Sense of sync with other changing actors (clocks, people, etc)
(hypothesis)
Experience to move in virtual time can be constructed by artificial stimuli
Virtual Time has more freedom
Speed manipulation, Warp, Loop, etc
🤔 What I want to do with this concept
1. Relativize the absolute "physical time"
2. Apply the most suitable style of "time" in different situations.
Not forcing virtual reality/time, but giving an alternative choice of reality/time.
⚗️ Applications
1. Virtual Time in Classroom Environment (2020)
https://gyazo.com/aa4aa6d64e61224f2d038972922c98e9
Interactive lecture video streaming platform
Student-generated content overlayed on lecture video
Goal: Combine merits of real-time and on-demand lectures
Merits of real-time lectures: Interactive communication between students
Merits of on-demand lectures: Control of time
Method: Virtual time by giving artificial stimuli
1. Psuedo Sync 擬似同期
Gives pseudo sense of sync with other students interacting on lectures
2. Elastic Sync 弾性同期
Secretly control playback speed within range of 0.9~1.2x
Sync unsynchronized students

2. Multi-threaded Voice Communication (WIP)
Issue of current voice communication: Only one thread available
Difficult to have branches of discussion
Applying Elastic Sync to create multithreaded voice communcation, where participants eventually receive content of every threads
🔬What to research?
some ideas:
1. Applying the concept: Multi-threaded Voice Communication
Human-Computer Interaction, Computer Mediated Communication
Applying time-compression algorithms & knowledges from cognitive science
2. Psychology / Neuroscience research?
but I want to do engineering & applied science, not basic science
3. Philosophical study of time being virtual
Prof. Jenann Ismael @ Columbia, philosophy of mind, metaphysics, time
