Electronic textiles provide an e ective platform to contain wearable computing elements, espe-

cially components geared towards the application of activity recognition. An activity recogni-

tion system built into a wearable textile substrate can be utilized in a variety of areas including

health monitoring, military applications, entertainment, and fashion. Many of the activity

recognition and motion capture systems previously developed have several drawbacks and lim-

itations with regard to their respective designs and implementations. Some such systems are

often times expensive, not conducive to mass production, and may be dicult to calibrate.

An e ective system must also be scalable and should be deployable in a variety of environ-

ments and contexts. This thesis presents the design and implementation of a self-contained

motion sensing wearable electronic textile system with an emphasis toward the application of

activity recognition. The system is developed with scalability and deployability in mind, and

as such, utilizes a two-tier hierarchical model combined with a network infrastructure and

wireless connectivity. An example prototype system, in the form of a jumpsuit garment, is

presented and is constructed from relatively inexpensive components and materials.
