`
`NOTeven a mundane cough escapes notation in Jennifer Healey's
`diary. Instead of waxing poetic about the simple pleasure of a cup
`of coffee or bemoaning the processof writing a thesis, Ms. Healey,
`a doctoral candidate in electrical engineering at the Massachusetts
`Institute of Technology's Media Laboratory, has begun recording
`her physiological responses to her environmentin the stark
`language of bits and bytes.
`
`Ms. Healey is experimenting with wearable sensors hooked up to a
`portable computer that she carries around but that might one day
`fit in the sole of a shoe. One day the system could be usedto build a
`personal security system that would snap a picture when the
`wearer wasstartled. Or it might track the specific causes of stress
`so the person could learn how to avoid suchsituations. But for now,
`she is just beginning to testit.
`
`Ms. Healey is discovering the myriad waysthat flaws can occur in
`the millions of bits of data she gathers about herheart rate,
`breathing, sweat gland secretions and muscleactivity, all of which
`are punctuated by pictures taken with a camera no bigger than a
`brooch.She is also learning to read the patterns of her data so that
`she can better interpret those produced by the people she will test
`this summer.
