This subway car hosts a Drum and bass rave.
I wish every car on the subway had an unwritten and unenforced, but well-understood theme. For example: If you’re with small children, take car #2. If you have pets, car #3. If you’re single and looking to mingle, car #4.
How would you get the message out, and what would be the best way to signify this to newcomers?
Similar to the “signals” (i.e., discoverability and feedback) inherent in good interaction design, how might we signal choices or a desired behavior to others?
