Article: A Smart Phone that Knows You're Angry
Researchers at Samsung have developed a smart phone that can detect people's emotions. Rather than relying on specialized sensors or cameras, the phone infers a user's emotional state based on how he's using the phone. The prototype system...enables people in a social network to view symbols alongside tweets that indicate that person's emotional state.
And if you're mad at your smart phone for misjudging your emotional state and telling everyone else its conclusions, will it detect that too?
