ALICE TURCHANINOVA UNIVERSITY OF HOUSTON-DOWNTOWN PROF. IOANNIS PAVLIDIS Analyzing Human Activity Patterns via Mobile App

Introduction 2 Overview 4 Activity Analysis 7 Network analysis 14 Goals 16 Acknowledgements iBurnCalorie: health and fitness app released by CPL. Current goal: carry out observational study of users in iBurnCalorie social network. Ultimate goal: offer users optimal pairing with other users to motivate physical activity. Method: analyze human walking and driving patterns and social network behavior with iBurnCalorie. 2

iBurnCalorie 2 Overview 4 Activity Analysis 7 Network analysis 14 Goals 16 Acknowledgements Allows users to keep track of their daily walking, biking, and driving activity. Includes a social networking component: users choose “buddies” to follow and compete against. 3

Persistency categories 2 Overview 4 Activity Analysis 7 Network analysis 14 Goals 16 Acknowledgements Users are divided into low, medium, and high persistency categories based on the number of days they have consistently used the application. Low persistency: 5 or less Medium persistency: more than 5, less than 10 High persistency: 10 or more 4
