`
`NOT even 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 process of 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 environment in 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 used to build a
`
`personal security system that would snap a picture when the
`
`wearer was startled. Or it might track the specific causes of stress
`
`so the person could learn how to avoid such situations. But for now,
`
`she is just beginning to test it.
`
`Ms. Healey is discovering the myriad ways that flaws can occur in
`
`the millions of bits of data she gathers about her heart rate,
`
`breathing, sweat gland secretions and muscle activity, 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.
