Remote Lecture Case Studies

  • Remote Lecture of Graduate School

–

  • ne or two Student(s) have presentation of
  • RFC or ID
  • Implementation application based on the documents
  • Q&A
  • Remote Lecture of Flesh man (B1)

– Flesh men(B1) came to my lab on every Tuesday for one semester. – They enjoyed talking with foreigner researchers/students with DVTS.

  • Both of these were done in regular classes
