Class Calendar 2013

Lectures (Tentative Schedule)

Lectures will take place in NSH 3002
Lecture Slides are available at https://github.com/jmankoff/data (to easily keep an up to date copy of it you will need to get yourself a git hub account (free) and then open the URL above. Click 'fork' and from then on it will show up in your repository. Github has a GUI that you can download which will update this when you request it. However you should create a separate place for your work and only use this to see my version of each project).

Bio: I am a researcher in the Technologies for Emerging Markets Group at Microsoft Research India. My research focuses on building appropriate information and communication technologies that contribute to the socio-economic development of low-income communities (ICT4D). This work often encompasses human-computer interaction (HCI), online education, mHealth, crowdsourcing, and other areas. Previously I worked on programming languages and compilers, for multicore processors as well as microfluidic chips. I received all of my degrees from the Massachusetts Institute of Technology, where I completed a Ph.D. in computer science in 2009.

Readings: Tomasic et alMotivating Contribution in a Participatory Sensing System via Quid-Pro-Quo. To Appear in CSCW 2014. [Blackboard] [Discussion of readings]
Bio: Aaron is an associate research professor in the Robotics Institute at Carnegie Mellon and the co-director of the Rehabilitation Engineering Research Center on Accessible Public Transportation. He earned his Ph.D., M.S. and B.S. in industrial & operations engineering from the University of Michigan (1999, 1994 and 1993, respectively) and completed a postdoctoral position at the University of California, Berkeley (2000). Steinfeld’s interest is focused around constrained user interfaces and operator assistance, predominantly in the realms of human-robot interaction, rehabilitation, transportation and intelligent systems. He is interested in how to enable timely and appropriate interaction when interfaces are restricted through design, tasks, the environment, time pressures, and/or user abilities. He works on the Tiramisu project. 

Tiramisu Transit is a crowd-powered transit information system developed by researchers to improve users' transit experiences and transit accessibility. With Tiramisu - literally Italian for "pick me up" - anyone waiting at a bus stop with a smartphone can see which buses or light rail vehicles are due to arrive next and, thanks to the signals from riders already aboard, get an idea of how long they have to wait. When a rider first activates the app, Tiramisu displays the nearest stops and a list of buses or light rail vehicles that are scheduled to arrive. The list includes arrival times, based either on historical data for that route or on real-time reports from riders. When the desired vehicle arrives, the user indicates the level of "fullness" and then presses a button, allowing their phone to share an ongoing GPS trace with the Tiramisu server.  Once aboard, the rider can use Tiramisu to find out which stop is next and to report problems, positive experiences and suggestions.

Readings:None
Speaker Bio: My research has covered a range of topics, including human-computer interaction, information visualization, bioinformatics, universal usability, security, privacy, and public policy implications of computing systems.  I have published more than 40 peer-reviewed journal and conference papers and two book chapters. At Towson University, I was an investigator on NSF-funded projects in computer security in introductory computer science classes and computational thinking.I am currently working on the development of highly-interactive, user-centered systems for finding and exploring biomedical datasets, with specific applications ranging from basic research data to electronic health records.. I have been a member of the Executive Committee of the Association of Computing Machinery's US Public Policy Committee (USACM) since 2004, and I am co-author of Research Methods in Human-Computer Interaction (Wiley, 2010).
