Calibrating+Datasets

Calibrating home datasets
In order to better compare home activity across datasets collected in different environments with varying sensor types and unique participants, we propose developing a calibration procedure that will help establish baseline metrics for each new dataset.

The following sample represents a calibration protocol that could be performed by participants in each study. These recommendations have been adapted from the contributions of Dr. Paul Lukowicz.

General Requirements

 * An activity rich procedure which activates a significant number of sensors and is spread over most rooms in the home
 * A combination of short, natural activities rather than a long complex procedure
 * Generic and reproducible activities that can be conducted in most home environments
 * Detailed audio/video recordings synchronized with sensor activations
 * Routine to be repeated at the beginning and end of data collection period, and possible midway through longer studies

Example Routine
> A. Walk to television viewing area, turn on television, sit down, and change the channel to ABC, NBC, or CBS (or equivalent) watch until first commercial break > B. Walk to stereo/music system, insert CD, turn on music, listen until selected track ends
 * 1) In bedroom, clap 5 times loudly at a rate of approximately once per second
 * 2) (Optional) Perform 5 jumping jacks
 * 3) Lie on your bed for at least 1 minute
 * 4) Get up and make the bed
 * 5) Get a pullover sweater or similar garment from your wardrobe and put it on
 * 6) Make a brief telephone call from any room
 * 7) Walk to the bathroom and wash your hands
 * 8) Walk to the kitchen and pour yourself a glass of water from a tap, dispenser, or bottle
 * 9) Make a simple sandwich
 * 10) Eat the sandwich and drink the water at a kitchen or dining room table
 * 11) Make a cup of tea or coffee (or hot water)
 * 12) Chose one of the following:
 * 1) Drink tea or coffee while watching television or listening to music
 * 2) Wash all dishes used in these activities either with a dishwasher or by hand
 * 3) Wash your hands in the kitchen
 * 4) Put on your shoes and seasonally appropriate outerwear; grab your house keys, purse, wallet, etc.
 * 5) Step out of your home, close the door, and wait approximately 1 minute
 * 6) Re-enter your home and put away any unnecessary items (outerwear, purse, etc.)
 * 7) Clap 5 times loudly at a rate of approximately once per second
