Abstract: Many people with cognitive and physical disabilities require some amount of assistance in daily living for their entire lives. Assistance ranges from mothering-style assistance to physical assistance with the most basic daily necessities. This population is underserved; much care is provided by a combination of family members and untrained staff. IoT systems can help provide both localized data and big-picture analysis to help these caregivers use their time effectively. This talk will discuss several results based on collaborations with my student Honggab Kim as well as Mihaela van der Schaar and Cathy Bodine. These results center on movement around the house: records of movement can be used to provide required logs of activity; comparison of day-to-day activity may also be useful as an indicator of wellness. Multitarget tracking uses observations from cameras distributed around the house, as well as other types of sensors that detect activity but no subject identification. Improvements in the problem, formulation and algorithms aid in the generation of tracks from observations. Adding non-appearance-bearing sensor observations can be used to generate tracks with modest loss in accuracy. Clustering analysis can be used to identify typical and atypical activity patterns. Both Levenshtein edit distance and dynamic time warping have been used in other applications but introduce some limitations; we will discuss the use of dynamic event warping as a metric for track clustering.
