Jason Kottke, nel 2005:

Pings would be perfect for situations when texting or a phone call is too time consuming, distracting, or takes you out of the flow of your present experience. If you call your husband on the way home from work every night and say the same thing each time, perhaps a ping would be better…you wouldn’t have to call and your husband wouldn’t have to stop what he was doing to answer the phone. You could even call it the “sweetheart ping” or “sweethearting”…in the absence of a prearranged “ping me when you’re leaving”, you could ping someone to let them know you’re thinking about them.

L’Apple Watch, e la Haptic Engine, promettono bene sotto questo punto di vista. Come si scriveva settimane fa, l’Apple Watch potrebbe trasformare le notifiche, da portatrici di messaggio a messaggio stesso, sfruttate come una sorta di codice morse privato.
