Ema's basic senario

Based on Ema (ver1.0: Ema for the first Fing presentation.),
I am re-thinking about basic scenario of Ema.

Whatever interfacewe are going to choose, I think we have to
think about these 3 results in one senario. Because, with Ema
(ver1.0) people needs to make the 2 stages of choice.


Choice 1.Ema (ON/OFF)
-This is the switch for the choice, whether the user wants to hear
the music from others.


Choice 2.The status of each music in users play list
(Public mode/Private mode)
-With this switch, for each music, user can choose whether they
accept to share the music or not.
(※Because sometimes, people might have very personal sounds
on their play list or something embarrasing to let others hear.
For example, I have a stupid music file which my friends made
for my birthday...)

Considering these 2 stages of choice, when two people pass by,
there is 3 possibility. (Red is A's music/Blue is B's music)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Result 1.
When two people are passing by, one can hear the other's music
(but the other doesn't). So they hear the same music at the same time.



Result 2.
When two people are passing by, they swap their music.



Result 3.
When two people are passing by, nothing happens(for Ema ver1.0).



Each condition
3*-As for this situation(condition), the users do not hesitate to
share their song, but each of them does not listen to others.
So for this situation, we might be able to use idea of "Toy story"/
"wind effect"[link]
