📕 Overview

• An iPad app for watching class videos

  • Combines synchronous and asynchronous student dialogue

• Background

  • Synchronous Interactive Classes: Individual playback control is not possible
  • On-demand Classes: Difficult to maintain student dialogue

Combining Synchronous and Asynchronous Student Dialogue

• “Synchronous” means: “Synchronization of Information” & “Synchronization Feeling”

  • “Synchronization of Information”
    • Exchange of two-way information/emotions
  • “Synchronization Feeling”
    • Feeling of sharing time synchronously
    • High temporal resolution creates a “synchronization feeling”

• “Synchronization of Information”

  • 
  • 
    • (The slope of the graph represents the playback speed)

• “Synchronization Feeling”

  • Pseudo-synchronization
  • Communication through handwritten characters
    • Sharing the process of writing characters creates a synchronization feeling

🕰 Student Synchronization

• Each device adjusts its speed by observing the playback position of other devices
• DBSCAN-like clustering
  • Strong attraction within the same cluster, weak attraction between different clusters
• Simulation
  • (Left: Changes in playback position, Right: Changes in speed)

👆 User Testing

• December 25th, 20:00-20:30

• For Apple Pencil owners

• Monitoring changes in playback position

  • (1s ~ 100s)

  • (1s ~ 250s)

• Manipulation of playback position is not observed much (unexpected)

• Reasons:

  • Because it’s just a test? 👍
  • Because they feel a synchronization? 👍
  • Is the relative operation UI difficult to use? 😢

💻 Miscellaneous

• Video Player https://youtu.be/PoyINyOhwLI

🖋 Users without Apple Pencil

• Dialogue methods with a synchronization feeling other than handwritten characters
• Honk: https://twitter.com/kenichiro_hara/status/1341575809127989248
  • Shared characters being typed in real-time
• Taking inspiration from Honk, a form of dialogue where the input process is shared through characters

🤔 Macro Discussion

• 

• This form of synchronization seems applicable beyond classes

  • Names like “Elastic Synchronization⭐️” or “Curved Synchronization”?

• Historical Progression

  • In the past: Asynchronous and vague time in each town
  • ➡️ Present: Physical distances have been shortened by transportation and the internet, leading to synchronous time
  • ➡︎ Future: Elastic Synchronization

🧭 Future Plans

• User testing/experiments
  • Testing at school after eliminating the need for Apple Pencil
  • Testing outside of school
• Final presentation
  • Distributing the app through App Store/Test Flight for presentation viewing- After explaining the overview and usage examples of the project, we will explain the future expansion of elastic synchronization.
