An Emotion Detector For Babies

Posted Mar 06 2010 5:22pm

Baby monitors of the future could translate infant cries, so that parents will know for certain whether their child is sleepy, hungry, needing a change or in pain. Japanese researchers have published a paper detailing their design for a statistical computer program that can analyze a baby's crying in the International Journal of Biometrics.

Studies done over the years have found that the pitch and frequency of a baby's cry can indicate a health problem. For example, a noisy, broken sounding cry can signal Sudden Infant Death Syndrome (SIDS) . A low cry with short utterances can suggest respiratory problems, increased tension or instability of neural control.

This is amazing, life saving technology. But I wonder if it will change they way we parent. I hope we don't lose the importance of also incorporating body language and non verbal cues of communication. But on the other hand, it could be a win-win, as Julien from Halfbakery says, if the translation of an infant's cry informs us that "Rock-a-bye baby sounds better in the key of C or that peas and carrots are not a winning combination".
