I would say…this is cool for communication in general, but it doesn’t seem to help at all with flirting. Even the comments seem kind of like how I feel after watching.

Sure, knowing is important, but how do you get to the knowing part? How do you understand that it even is flirting, how do you “get on the same wavelength”? How do you communicate subtly without being misunderstood? How can you be confident that your message was received, what are the signs?

Video is a good first note: consent in communication is key, but it doesn’t really offer much more.
