• The following is about kineto.

• We have limited space for writing when it comes to class videos, right?

• We might connect with HakoScope (an insta360 distributor).

• How should we store video data? Maybe using AWS?

• The issue of having two different approaches

  • Is this really a separate axis?

• Are we aiming for a private tutor-like experience?

  • Is one-on-one tutoring ideal? No, we also want to have discussions with multiple people.
  • It should be possible to ask friends for help when we don’t understand.

• When multiple people are delayed at the same pace, it might be a good idea to connect those who are falling behind.

• “Social Note-taking”

  • Since everyone is drawing on the same timeline, we might be able to share notes in a Nico Nico-like fashion.

• It’s okay to naturally fall behind while taking notes, so a modeless approach is good.

• When it comes to that, “do we really want to manipulate time with kineto?”

• I wrote various things about it in What do you really want to manipulate with kineto, time?

• Interesting experience with drinami

  • When participating in a Zoom meeting and then entering a real room in the middle
  • The sensation of lag being resolved is interesting.

• Discussion about “Research-like Development”

• Using people for user studies

  • Professor Sakamoto from Hokkaido University seems to be good at it.

• The following are things that should not be exposed about others.

• Making emojis a universal language

• Emoji input method 1 - Select from categories

  • It’s good but difficult (3000 choices).

• Input method 2 - Conversion during input

  • The choices are narrowed down, there is no randomness.
  • It doesn’t exist in English-speaking countries.

• We want to provide options while showing the best candidates.

• We want to avoid bias.

• Representing emojis in the same space as Japanese using word2vec

  • Challenge: Not being able to understand sentences

• Building models using BERT and EmojiNet

• Emojis can be interpreted in multiple ways

  • Mapping multiple vectors

• Creating a graph and suggesting the emoji that best matches

• It would be nice to express emotions through continuous use of emojis.

• Umpire training system

• Distinguishing between strikes and balls

• The problem is the error rate

  • It’s especially a problem for amateurs
  • Machines that can determine whether it’s an error or not are expensive, and umpires can’t even practice

• There was a discussion about how spectators express dissatisfaction with incorrect calls. Based on what information do spectators determine whether it’s an incorrect call or not?

• I don’t know much about baseball, but personally, I was surprised that humans are making these judgments.

• The benefits of humans making judgments in baseball

  • The culture of framing would disappear, so machine judgments are not good.

• In fencing, humans can’t determine the outcome with their own eyes

  • If humans can’t determine the outcome, the value of cheering decreases
  • It’s an important point in sports.

• There is also a problem that hearing-impaired individuals have difficulty in sports development.

• The collar on the neck is suitable for haptics, so we can transmit sound through the neck.

• Question

  • One thing that caught my attention is whether there are any effects on hearing through the neck or if it makes able-bodied individuals even stronger.

• In the future, for sports as a whole

• Direction where able-bodied individuals can also enjoy

  • Inclusive
  • Good for business as well

• Issue of body orientation

  • If only the face is turned to the right, which is the “front” in terms of coordinates?

• In engineering, it has historically been only “militarily useful”

• You don’t have to worry so much about whether what you’re creating is “useful” in society.

Overall message

• We should delve into the moments that make us go “wow.”- Example: In a video delay demo, there are moments when the delayed video sticks together.
• Simply packing it logically may be sufficient for a paper, but it tends to become boring.
• Emotions are also important.
• They can also serve as a source of motivation for development.
