This semester I am co-teaching Societies of the World 47: Contemporary Developing Countries: Entrepreneurial Solutions to Intractable Social and Economic Problems. Led by prof. Tarun Khanna from Harvard Business School and co-taught by faculty from medicine, humanities and the GSD (and me), this course brings a fiercely interdisciplinary approach to some of the world's toughest problems. Join us! Mondays and Wednesdays 3:30–5:00 pm in Sever Hall Rm 113.
Thursday, July 30:
Juho defended his thesis on Learnersourcing: Improving Learning with Collective Learner Activity. After a brief postdoc at Stanford, he is going to become a professor at KAIST. Congrats!

We are organizing a AAAI Spring Symposium on Intelligent systems for supporting distributed human teamwork to bring together researchers in Social Sciences, HCI and AI in pursuit of novel approaches for supporting the increasingly more distributed and more complex teamwork. The deadline for submitting position papers is on October 9. Organizers include Ofra Amir, Ya’akov (Kobi) Gal, Barbara Grosz, Jonathan Grudin, Robert Kraut, Gary Olson and Peter Stone. Please consider joining us!

Monday, September 1:
We will be presenting three papers at CSCW'15:
- "Toward Collaborative Ideation at Scale — Leveraging Ideas from Others to Generate More Creative and Diverse Ideas" -- new crowd- and machine learning--powered system to pick out sets of diverse high quality examples of ideas generated by earlier contributors to inspire future contributors. Increases quality and diversity of generated ideas.
- "Learnersourcing Subgoal Labels for How-to Videos" -- today's learners make tutorial videos even better for future learners by contributing to non-trivial human computation tasks as a byproduct of doing things that they are already motivated to do.
- "LabintheWild: Conducting Large-Scale Online Experiments With Uncompensated Samples" -- data obtained through LabintheWild are as good as the data collected in traditional lab-based studies.
Final versions of these papers will be online in a few weeks.
Tuesday, August 12:
The focus of this year's CS 279 will be social computing and crowd-powered systems. Specifically, we will look at the design and analysis of systems, in which crowds of intrinsically motivated volunteers contribute to meaningful and non-trivial human computation tasks as a byproduct of doing something that they are motivated to do anyway. The course is designed for first year grads from all areas. Advanced undergraduates are also welcome, particularly those who wish to do reserach (or write a thesis) in an area related to Human-Computer Interaction.
Monday, August 11:

Thursday, May 15:
Ken Nakayama (psychology), Ryan Enos (government) and I received a grant from the Harvard Initiative for Learning and Teaching for integrating online behavioral research modules into the classroom. Essentially, we want to bring the kind of experiential learning (lecture demonstrations, open-ended labs) that is common in natural sciences to education in psychology, social sciences and HCI.

Sunday, October 27: In collaboration with the Center for Research on Computation and Society (CRCS), we are now accepting applications for 1- or 2-year Postdoctoral Fellowships. Consider applying even if you are currently seeking a faculty position. Many schools will let you defer your faculty position for a year and a Fellowship at CRCS is a great way to develop your research agenda and to expand your research network.
Friday, October 25: Our team (led by Mary Regan at UMD School of Nursing) received an R01 NIH grant to study the behavioral and nutritional factors impacting pre-term birth. A key technical enabler of this project is a mechanism, based on our PlateMate system, for scalable nutritional analysis, which will make it possible to track the nutritional intake of 400 pregnant women for several months each.
Monday, October 21: Louis Li presented a poster on his work on Adaptive Click-and-Cross at the ACM ASSETS conference. Adaptive Click-and-Cross combines several adaptive mechanisms (which were previously studied in isolation) to improve the efficiency of computer access for people with impaired dexterity.

Friday, October 11: I have joined Tony Jameson as a co-Editor in Chief of the ACM Transactions on Interative Intelligent Systems (TiiS). I am helping fill the unfillable gap left by the passing of John Riedl, who was one of the two founding EICs of the journal. TiiS aims to be the primary venue for research that bridges HCI and AI (both broadly construed). Please consider submitting.
Sunday, Sept 22: Reminder: CrowdCamp applications are due on Sept 25! Next CrowdCamp (a two-day hack-a-thon for prototyping novel crowd-powered ideas) will take place at HCOMP'13 and will be lead by a great team: Lydia Childton (UW), Juho Kim (MIT) and Pao Siangliulue (Harvard).
Sunday, September 8: At HCOMP 2013, we will present a demo of Curio, a crowdsourcing platform that connects interested citizens with researchers to help answer important questions in the sciences and humanities.
Read the abstract.
Monday, September 1: Detailed timeline is now available for CS 279: Topics in Human-Computer Interaction Research. The course is designed for first year grads from all areas and for dvanced undergrads, particularly those who wish to do reserach (or write a thesis) in an area related to Human-Computer Interaction. Special focus this year is on human-computer interaction research at scale, i.e., large-scale online experiments, crowdsourcing, and social media analysis. Class will meet on Tuesdays and Thursdays, 10-11:30am, in Pierce 100F.
Monday, July 22: on Monday, July 15, John Riedl passed away. John was best known for his pioneering work on recommender systems and social computing. I found John's research particularly admirable because it combined exciting technical contributions with deep insights into social psychology, thus merging the technical and the human in ways that were rigorous, informative and inspiring. Several years ago, John became the founding editor of the ACM Transactions on Interactive Intelligent Systems (TiiS), a flagship journal for research combining advances in AI and Machine Learning with rigorous insights into Human-Computer Interaction.
Steven Snyder wrote a more extensive piece in memory of John. If you would like to honor John's memory in a more tangible way, you can donate to a scholarship fund set up by University of Minnesota in John's memory.
Saturday, July 20: At long last, we have published a data set to accompany our 2011 PlateMate paper. The data set contains 16 out of the 18 images we used to evaluate PlateMate's accuracy. The data set also includes the ground truth nutritional info for each photograph, expert estimates, as well as PlateMate's estimates.
Monday, June 24: We are gearing up to launch Curio, a crowdsourcing platform that connects interested citizens with researchers to help answer important questions in the sciences and humanities. Sign up now to receive an early access invitation!
Friday, May 31: More than 500,000 people have participated in experiments on Lab in the Wild.
