If you watched the new iPhone 4S commercials that Apple released last night, the ones that feature John Malkovich asking Siri for jokes and about the meaning of life, you might have noticed the way in which he was asking. In short, it was short. David Chartier certainly noticed:
Joke features him speaking a series of one-word commands to Siri that practically feel like verbal equivalents of tapping on a particular app to get a particular piece of information. "Weather." "Evening." "Linguica." "Joke." Apple seems to want to remind us that, underneath the clever responses and artificial personality, Siri is a tool meant to help us get more done with less.
Talking to Siri like it's a Pixar character certainly makes it more endearing, and makes the virtual relationship seem more real. The commercial shows, however, that if you don't have time or simply aren't in the mood for pleasantries, you can get to the point with machine-like brevity.
Unfortunately, for all of Siri's context awareness, it doesn't seem to notice when your communications are rushed and respond in kind. As the commercial also shows, even one short word like "life" can return a paragraph-long reply.
