Weight monitoring in bed using E-scale.
Doctoral Dissertation, University of Pittsburgh.
(Unpublished)
Abstract
Wheelchair users are more than twice as likely to be obese compared to the general population. This is not surprising considering that it is challenging for wheelchair users to monitor their weight as well as maintain an active lifestyle, both of which are factors that strongly influence a person’s ability to manage their weight. The E-scale is a weight monitoring system that was designed for wheelchair users to be able to weigh themselves frequently in their homes. It is comprised of a set of weight sensors that are placed under the legs of a bed or other piece of furniture and passively and continuously measures the weight on each bed leg. This dissertation focuses on the design evolution of the E-scale, and specifically on developing and testing two key aspects of the E-scale that are related to its commercial viability. To make sure that the E-scale can be used in the common scenario where beds are shared by a couple, algorithms for monitoring and differentiating the weight of multiple people using the same bed were developed. To test the usefulness of the E-scale, a weight loss study for wheelchair users was conducted to determine if the E-scale is a feasible technology to use along with a standard behavioral weight loss program adapted specifically for wheelchair users. The results of these two studies as well as a description of future work and preliminary discussions of other applications of the E-scale are reported.
