44. Fundamentals - Possible Question
● Will Metaverse hype continue to drop off?
● What’s the relationship between impressive experience and used gears?
● Do you think events happening in the metaverse would replace the real world ones?
● Can we do analytics on centralized metaverse ?
● In your opinion, which is better centralized or decentralized metaverse ?

45. Fundamentals - Possible Question
● What is the difference between virtual reality and
Metaverse?
Methods and Challenges for Metaverse Analytics | SS 22
Page 44
46. Biometric data
● Malicious users can monitor and collect metaverse users behaviour (eg. interaction with other users, purchase
actions) and biometrics (eg. facial expressions, vocal inflections) in real time, which could be used to
recognize the user.
● Use eye tracking sensors
● Recordings of people’s faces and emotional states, and possibly bodily movements might be required to
create virtual avatars.
● Incorporate facial recognition technology and use it to identify random passers by and collect and transmit
their location data back to the developers.
● Users creates various data such as intimate information (eg. messages, voice, and video), corporate secrets
used for work, and the personal information needed for service to continue.
● Its not clear yet how companies would use such data, but history shows its unlikely that all of this new data is
going to be handled in a way that is good for user privacy
Methods and Challenges for Metaverse Analytics | SS 22
Page 45
47. High data volume
● Every person who enters the metaverse creates a data file, data continues to grow as a result of social
interaction
● Data labelling and data organization will be a challenge with huge amounts of data produced by metaverse
application
● Data produced will be huge, unstructured and real time
● Current computation is not yet powerful enough to host thousands, or millions, of people in a live, shared,
persistent, synchronous space, highlighting another hurdle for the metaverse to overcome
