Level of Detail in Motion Science Associated with Older Adults

It is a well-know statistics that the percentage of our elderly population will globally surpass the other age groups. Majority of the elderly would still prefer to keep an active life style. In support of this life style, various monitoring systems are being designed and deployed in order to have a seamless integration with the daily living activities of the elderly while preserving various levels of their privacy. Motion tracking is one of these health monitoring systems. When properly designed, deployed, integrated and analyzed, they can be used to assist in determining some on-sets of anomalies in elderly health at various levels of their movements and activities. In this paper, we propose to divide the overall motion tracking of the elderly into three levels were at each hierarchical level, information regarding movement patterns can be analyzed ranging from global motion patterns to more detailed gait patterns. Depending on the state of frailty of elderly, this hierarchical break-downs can allow the medical personnel and physicians options for deploying sensing system which offers different degree of granularity in motion sensing. These levels are defined as: a) coarse global path of mobility between various key nodal points in the monitoring area; b) the trajectory of motion between each of the key nodal points and c) the gait patterns along the motion trajectories between the key nodal points. In this paper we presents an overview of these levels and associated tools which can be utilized in order to further explore and define motion patterns that can be utilized by data scientists and medical personnel as a part of the prevention analysis.
