Configuring the SenseWear® Pro2
Armband
The InnerViewTM Research Software enables you to configure and reconfigure your
Armband for multiple purposes and users. In general, the Configure SenseWear section is
where you enter the wearer's personal body stats, customize the Armband's parameters,
and optimize your data collection channels. However, the most important thing to know
about this section is that the accuracy of the derived data depends on accurate user
parameters.
To configure your Armband:
1. Remove the Armband from your arm and attach the USB cable. You cannot
configure the Armband wirelessly.
2. Click Configure SenseWear.
3. Next, click Retrieve Configuration. This will pop up a screen indicating retrieval
progress.
4. If multiple Armbands are connected to your computer, a dialog box will appear
prompting you to choose which one you wish to configure.
5. Once the configuration is retrieved, you should be looking at the SenseWear
Parameters tab. From here you can customize the settings for each subject's body
parameters.
NOTE: If you are configuring Armbands for multiple subjects, you may choose to enter body
parameters by clicking on the subject when you upload the data. Changing settings here will alter
the subject's body parameters for the individual data file.
6. You can configure the data channels for the Armband by choosing the data
channels tab.
SenseWear Parameters Tab
1. Click on the SenseWear® Parameters tab
2. First, check to see if the SenseWear® Pro2 Armband is initialized with the correct
date and time. If it is correct, proceed to step 5.
3. If the time is not correct, it is due to one of two reasons:
a. The Armband time was reset due to low battery voltage, indicated by red
text. Click Apply and this will set the Armband clock to match the
computer clock.
b. The computer clock is incorrect. To reset your computer clock, double-
click on the clock located in the right side of your task bar. This will pop
up your computer's Date/Time Properties window. Correct the date and
time, then press OK.

4. In the InnerView
software, click Apply.
Body Parameters Tab
1. Enter the subject (name or code of person wearing the SenseWear® Pro2
Armband), birthdate, height, weight, sex, handedness and smoking preference.
2. Click Apply.
Data Channels Tab
The SenseWear® Pro2 Armband has 4 configuration options available for data collection.
1. Algorithims - This configuration is the minimum set of data channels need to
calculate energy expenditure and lifestyle algorithims at a sample rate of once per
minute.
2. High Rate - This configuration is for collecting High Rate data from the
Armband.
3. Research - This configuration collects all of the channels necessary for lifestyle
and energy expenditure algorithims at the rate of once per minute. This
configuration also collects data from proprietary channels that will be used in
future versions of this software.
4. Custom Channel Configuration - With this option, you may customize your
channel configuration. Once a data channel is turned on, you can customize the
sampling rate by using the dropdown menu or you may choose a sample rate for
all channels from the dropdown on the left. Keep in mind that changing this value
from one will either increase or decrease the estimation of total continuous data
collection.
To turn a data channel on/off, click the checkbox to the left of the data channel
name. Keep in mind that turning channels on/off will change (either increase or
decrease) the estimation of total continuous data collection. At the bottom of the
screen, you will see the estimation of total data the Armband can collect before it
runs out of memory for the configuration that you have chosen.
NOTE: You can save custom settings to a file by clicking the "Save Settings to
File" button. You can then use the "Load Settings from File" button to retrieve
your custom configurations.
The estimated total collection time is affected by the number of times the Armband
is off body. The more times the armband goes off body the more the calculation
will overestimate the actual time.
5. Custom Channel Configuration With Lifestyle Algorithms - This is a procedure
by which you can create a custom configuration that is capable of utilizing
BodyMedia's Lifestyle Algorithms.
1. Load one of the above standard configurations on the armband
(Algorithms, High Rate or Research)
2. Save the configuration.
3. Re-Load the Armband Configuration (the screen will show the standard
configuration that you just loaded).
4. Click Custom Configuration.
NOTE: From here, you can add custom channels at 1 per min sampling
rate or faster
5. Save the configuration.
You should now be able to collect data and still use BodyMedia's Lifestyle
Algorithms. For further assistance on customizing configurations, please contact
BodyMedia, Inc.
Description of the Data Channels
The SenseWear® Pro2 Armband contains 24 data collection channels, which can collect
physiological data at a rate up to 32 times per second. Usually the Armband is configured
to store statistical summaries of many samples over time. The summaries are calculated
and stored once per collection period. The default collection period for data is one
summary per minute, but this rate may be changed in the Data Channels Tab of the
InnerView
There are two main types of statistical measures available with SenseWear; average and
mean of absolute differences (MAD). Average is the sum of the point samples divided by
the number of samples in the collection period. MAD is the mean of the absolute values
of the differences between adjacent point samples summed over the collection period. For
example, if the sample rate of the skin temperature sensor is set to one minute, then the
average stored is the average temperature reading from the following samples (32
samples a second X 60 seconds = 1920). The MAD is the mean of differences between
adjacent samples. Being means, both average and MAD are sample rate independent.

Averages and MAD's at one minute sample rates are comparable to those taken at any
other sample rate.
Additionally, the accelerometers can record peak counts. Peaks are points in the
accelerometer signal where acceleration has reached its highest point relative to the
samples immediately surrounding it. The point sample channels allow the experimenter
to record all accelerometer samples acquired at 32 samples per second.
The Armband measures several basic physiological quantities in the various ways
described above. Below are descriptions of each of these physiologic measures.
Accelerometer
• Description: An accelerometer measures motion forces exerted on the body in a
single plane. Static and dynamic forces are measured in two perpendicular axes:
longitudinal which is parallel to the arm and transverse which is perpendicular to
the arm.
• Channels: There are a total of 8 accelerometer channels. They are:
1. Transverse Accelerometer - point
2. Transverse Accelerometer - peak
3. Transverse Accelerometer - average
4. Transverse Accelerometer - MAD
5. Longitudinal Accelerometer - point
6. Longitudinal Accelerometer - peak
7. Longitudinal Accelerometer - average
8. Longitudinal Accelerometer MAD
• Technology: The accelerometer is a 2-axis micro-electro-mechanical sensor
(MEMS) device that measures motion.
• Units: Meters per second squared relative to earth gravity. For example, a data
reading of 1 is one earth g, or approximately 9.8 meters per second squared
(m/s²).
• Calibration: Two known orientations.
• Scenario: The accelerometer MAD is a measure of stillness and movement. For
example, while sitting still watching a movie, the accelerometer MAD values will
be near zero, but while jogging the accelerometer MAD values will be high. The
accelerometer average is a measure of both acceleration and orientation relative to
the ground. For example, a sleeping person may not be moving, but can still
register 1g acceleration due to gravity. On a roller coaster, a person may be
subject to higher than normal average accelerations. The peaks summary is related
to the frequency of vibration to which the wearer is subjected. An Armband worn
by the person riding the roller coaster will record large counts in the peaks
channel whereas the sleeper will likely generate values near zero.
