The proliferation of mobile devices has given rise to novel user-centric applications and services. In current mobile systems, users gain access to remote servers over mobile network operators. These operators are typically assumed to be trusted and to manage the information they collect in a privacy-preserving way. Such information, however, is extremely sensitive and coveted by many companies...

OBJECTIVE Self-monitoring of physical activity (PA) and diet are key components of behavioral weight loss programs. The purpose of this study was to assess the relationship between diet (mobile app, website, or paper journal) and PA (mobile app vs no mobile app) self-monitoring and dietary and PA behaviors. MATERIALS AND METHODS This study is a post hoc analysis of a 6-month randomized weight...

Mobile learning has received an increasing attention by the TEL community since 2010. While much research is available on the effectiveness of individual apps and educational approaches and despite that many higher education institutions introduced special mobile learning apps, relatively little is known about the rationale of scaling up mobile learning in higher education institutions.

This paper evaluates the relationship between auditory contexts, hearing aid features, and hearing outcomes based on real-world measurements. We use a mobile phone application to concurrently evaluate the auditory contexts and hearing aid outcomes using Ecological Momentary Assessments. The collected dataset includes 3437 surveys collected from nineteen patients over ten months. Our analysis in...

In this article we discuss an architecture for mobile agents. We focus on the components in the architecture that provide eecient, reliable, secure transportation of agents and ditto communication between agents and their environment. These components provide the basis for building a wide variety of agents with various levels of intelligence. We further discuss a prototype of the system, built ...
