Users on metered Internet connections can be subject to data caps or quotas on the amount of data they can send during a billing cycle. In most cases, metered connections force Internet users to perform a careful balancing act of meeting data needs versus limiting the demands of data-intensive applications, the cloud, and multiple users. Yet we understand very little about how to help consumers to track and control their Internet data usage to meet everyday goals. In this talk, I describe how we used a user-centered approach to create and evaluate a tool called uCap that helps users monitor and control data usage from Internet-connected devices in their homes. uCap was deployed in 21 homes in South Africa, India, and United States. During the study, we collected measurements on data usage and used surveys and interviews to study 10 of these homes in depth. I describe the results of our evaluation and suggest directions to pursue for empowering users to learn about, monitor, and control Internet data usage in the home.
