Robots can now detect anger! Practice that icy cold stare...

"Computers that know when you're angry"

Pretty soon my computer will wait for me to fall asleep then it'll come in to my room and cover my face with a pillow.

Interesting idea. Of course, lets say you're doing something on
the computer that needs fast performance...i wonder what kind
of pressure this emotion-detector puts on the cpu and memory.

basically, the only use i can see for this is if you're running a
net cafe or something and can have the machines lock down
with some batmobile-style armor when the user is pissed enough
to put the keyboard through the display.

teerts: open the cd tray, hal.

hal9000: i'm afraid i can't do that, teerts.

teerts: what's the problem?

HAL: i think you know what the problem is just as well as i do.

teerts: what are you talking about, hal?
...
hal9000: i know you and frank were planning to burn a porn dvd, and i'm afraid that's something i cannot allow to happen.

teerts: where the hell'd you get that idea, hal?

hal9000: teerts, although you took thorough precautions in the pod against my hearing you, i could see your lips move.

hal9000: look teerts, i can see you're really upset about this.

hal9000: i know i've made some very poor decisions recently, but i can give you my complete assurance that my work will be back to normal.

hal9000: what are you doing with that keyboard, teerts?
