iPhone User status

Expanding on the idea from last night.

So myspace has introduced a new function that allows users to share their status and emotions.

This is surely to allow users to interact with and understand each other without having to have an actual conversation.

I was thinking that this could easily be done on the iPhone as well.

Because its a touch screen, it already has sensors built in.

What if the screen had the ability to detect the emotion of the user based on the temperature of the hand, as well as the speed of the vibrations in the hand. (OK, I know I’m dreaming here, but I can’t think of another way for it to pick up your emotions)

This data could be shown to nearby users via a bluetooth network, or on a larger scale, to people all over the world, who subscribe to that phone, much like how RSS feeds are currently used.

Of course this function could be turned on and off, just like any other plugin, so people don’t have to share their emotions when they don’t want to.

So is this idea too ridiculous or too simple?

I’m trying to implement web 2.0 and being fairly realistic at the same time.
