You're out and about and you get a new email on your phone. Instead of a single notification from the device to alert you that you have a new message, the area on the floor around you begins to glow a bright blue, indicating that you have a new message. You see this, and pull out your phone. It's a message from your sister. You enter a quick reply, send it away, and you're done, free to go about your day knowing that you haven't missed out on any important messages.
