I would like to thank Prof. David Levine with all my heart for encouraging me, motivating me and tracking my progress throughout the work that was being done. It would not be possible without your belief in me and tons of anecdotes from your experience. Thank you again for enlightening me through the path of my career and all the wisdom that I have gained under your supervision. I would like to thank all my committee members, for their patience, faith and confidence in me. I thank Dr. Khosrow Behbehani for his fruitful insights and guidance for the fruition of this project and systematically guiding the way and motivation. I thank Dr. Christoph Csallner to provide me insights on the aspects of software engineering, motivating to pursue something that I believe in and identifying the potential in me. I thank my parents, Mr. Girish Shirolkar and Mrs. Sumati Shirolkar, without their constant care, hope, faith, motivation, and confidence in me I cannot imagine the completion of this thesis. I thank Purva Sugandhi for always being there and having a very patient and perseverant effort at listening and constantly motivating me towards achieving my goals. I thank all the people, my friends, family, relatives, classmates, colleagues, acquaintances whom I have not included here specifically, but they have played an important role in the pursuit of my higher studies and goals. November 3, 2016 iii Abstract REMOTE PATIENT MONITORING USING HEALTH BANDS WITH ACTIVITY LEVEL PRESCRIPTION Pranay Shirolkar, MS The University of Texas at Arlington, 2016 Supervising Professor: David Levine With the advent of new commercially available consumer grade fitness and health devices, it is now possible and very common for users to obtain, store, share and learn about some of their important physiological metrics such as steps taken, heart rate, quality of sleep and skin temperature. For devices with this wearable technology, it is common to find these sensors embedded in a smart watch, or dedicated wearable wrist bands such that among other functionalities of a wearable device, it is capable of smartly assisting users about their activity levels by leveraging the fact that these devices can be, and are typically, worn by people for prolonged periods of time. This new connected wearable technology has a great potential for physicians to be able to monitor and regulate their patients’ activity levels. There exist many software applications and complex Wireless Body Area Network (WBAN) based solutions for remote patient monitoring but what has been lacking is a solution for physicians, especially exercise physiologists, to automate and convey appropriate training levels and feedback in a usable manner. This work proposes a software framework that enables users to know their prescribed level of exercise intensity level and then record their exercise session and securely transmit it wirelessly to a centralized data-store where physiologists will have access to it. iv Table of Contents Acknowledgements
