1 Introduction to the MotionWatch System

1.1 An Overview of

the MotionWatch
System

The MotionWatch is a compact, lightweight, body-worn
activity monitoring device that may be used to document
physical movement associated with applications in
physiological monitoring. The device is intended to monitor
limb or body movements during daily living and sleep. The
MotionWatch can be used to assess activity in any
instance where quantifiable analysis of physical motion is
desired. MotionWare allows for the set-up, download and
analysis of data captured with the MotionWatch. The
MotionWatch also incorporates a light sensor to record
luminous intensity (lux) of white light and an event marker
button. Utilizing the latest low-power MEMs technology,
the MotionWatch provides a convenient, flexible platform
for Actigraphy studies of all sizes. See Appendix D
