This study is part of a research project led by Jian Zheng (jzheng23@umd.edu) at the University of Maryland, College Park. The purpose of this survey is to understand how people spend their daily time and, especially, those waiting times. It includes three interviews (up to 2 hours in total), daily brief surveys (up to 5 minutes each day) lasting for two weeks (up to 70 minutes in total), and two applications to be installed on your computer and phone. Full participation will take no more than 4 hours and be rewarded with a $100 gift card. Partial participation (e.g., installing only one or none of the applications) is also welcome.
