Annotating The Data - BodyMedia SenseWear User Manual

Activity Classifications
"Activity Classifications" can be selected in the data chooser. This is a statistical analysis of the
data that matches the recorded sensor patterns to activity. Under steady state conditions, the
activity classifications indicate the activity from the set with the highest probability (figure 15).

Annotating the Data

The SenseWear Software allows you to make annotations to a data file. For example, if the
data shows a spike in physical activity you can add an annotation that describes what the
wearer was doing for that specific time period. Annotations can be added to data files from the
View & Annotate Data screen (figure 6). Check the Show Sessions & Timestamps box (figure
16). A list of Session Start and End times as well as any Timestamps will appear in the window
below.
Figure 16
The Session Start and End times demarcate periods when the device was continuously on-
body. To annotate either an entire session or an event within the session, click on the Session
Start time and Shift-click on the Session End time. Then click the Add Annotation button
above and to the right of the Sessions and Timestamps window. A list of annotations will
appear (figure 17). Choose one from the list and click OK.
