No more poker face: it’s only a matter of time before machines will be able to read our emotions
Eye dilation reveals how hard a brain is working, and heat radiating from the skin signals whether we are stressed or even romantically piqued

Dolby Laboratories chief scientist Poppy Crum tells of a fast-coming time when technology will see right through people no matter how hard they try to hide their feelings.
Sensors combined with artificial intelligence can reveal whether someone is lying, infatuated, or poised for violence, Crum detailed at a big ideas TED Conference.
“It is the end of the poker face,” Crum said. “We broadcast our emotions. We will know more about each other than we ever have.”
Eye dilation reveals how hard a brain is working, and heat radiating from the skin signals whether we are stressed or even romantically piqued.
The amount of carbon dioxide exhaled can signal how riled up someone, or a crowd, is getting. Micro-expressions and chemicals in breath reveal feelings.
The timing of someone’s speech can expose whether they are at risk of dementia, diabetes, multiple sclerosis, or bipolar disorder, according to the neuroscientist.
