A sensor, from the Latin sēnsus: sense or feel, is a device that measures physical properties (e.g., motion, light, heat) that describe the current state of a system or environment. The sensed data can not only be processed and analyzed to learn about the system or environment, but it can also be integrated into a solution to solve problems we encounter in everyday life. At IBM Research - Almaden, my research has focused on building solutions that use inertial sensors, wireless sensors, and other sensing technologies to explore and learn about us and our surroundings. As a Research Staff Member at IBM Research - Almaden in the IoT and IBM Cloud and Mobile Enterprise Research team, one of the solutions I have been working on is the use of Bluetooth Low Energy beacons, inertial sensors, and other wireless technologies for IoT related applications. Some of our work and collaboration has been featured in the IBM Research Blog and ABC7 News.
I received my Ph.D. degree in Computer Engineering from the University of California, Santa Cruz, in September 2017 under the supervision of Prof. Roberto Manduchi. My dissertation focused on developing navigation systems to help blind people navigate in indoor/outdoor environments. In particular, I developed a system to help blind people retrace the path taken inside a building and walk safely back to an initial location. This is ideal for situations in which a blind person is able to reach a certain location, for example with the assistance of a sighted guide, and needs to find his or her way back to the initial location. This robust path back-tracing guidance system was comprised of a turn detector based on a hidden Markov model (HMM) to robustly detect turns even in the presence of drift in the inertial measurements and noticeable body sway during gait, a step counter that uses filtered inertial sensor data to determine the number of steps walked along a path, and a path matching algorithm to track the user's location. This work has been mentioned in UCSC NewsCenter.
