Tag-free Indoor Position Tracking


A passive tag-free approach to localization and activity monitoring

Program Eligibility

BS, MS, or PhD

Funding Source

Alzheimer’s Association


Up to 2 years


The goal of this project is to develop a new approach to passive tag-free localization and activity monitoring in support of seniors with Alzheimer’s disease.  While most in-home monitoring systems require a person to carry a device or tag, our approach requires no such tag, and works unobtrusively in the background.  The method enables accurate indoor localization while also estimating mobility and other measures of activity, including monitoring interactions with a caregiver.   Studies will take place in labs at OHSU and in the homes of
volunteer seniors.


The student will assist in setting up hardware and performing data collections.  Research will involve data analysis, feature extraction, and the design of classifiers to perform indoor tracking and activity monitoring.


Prior classwork in signal processing, statistics, and experience in MATLAB and C/C++ programming.  Additional background in machine learning, pattern classification, wireless and embedded systems is also desired.
