A reminder that today we have a Member Presentation by Prof. Ashton Anderson in the DGP lab at U of T (40 St. George St.<https://www.google.com/maps/place/40+St+George+St,+Toronto,+ON+M5S+2E4,+Can…>, 5th Floor). Come help your brain work off that Thanksgiving Tryptophan with some mental stimulation. Lunch at 12:30, talk at 1:00pm sharp. We look forward to seeing you there, Ali, Daniel, and Tovi Ashton Anderson: The Design of Social Incentives 2018-10-09 12:30 at DGP Lab: 40 St. George St., 5th Floor<https://www.google.com/maps/place/40+St+George+St,+Toronto,+ON+M5S+2E4,+Can…> [http://www.tux-hci.org/wp-content/uploads/2018/10/ashton.jpg-150x150.jpeg] Abstract An increasingly common feature of online communities and social media sites is a mechanism for rewarding user achievements based on a system of social incentives, such as badges. Badges are given to users for particular contributions to a site, such as performing a certain number of actions of a given type. In this talk, I will speak about how badges can influence and steer user behavior on a site-leading both to increased participation and to changes in the mix of activities a user pursues on the site. I'll introduce a formal model for reasoning about user behavior in the presence of badges, and in particular for analyzing the ways in which badges can steer users to change their behavior. To evaluate the main predictions of our model, we study the use of badges and their effects on the widely used Stack Overflow question-answering site, and find evidence that their badges steer behavior in ways closely consistent with the predictions of our model. We then investigate the problem of how to optimally place badges in order to induce particular user behaviors. Several robust design principles emerge from our framework that could potentially aid in the design of incentives for a broad range of sites. Finally, I'll report on a large-scale deployment of badges as incentives for engagement in a MOOC, including randomized experiments in which the presentation of badges was varied across sub-populations. We find that badges significantly increased student engagement, with the magnitude of the increase varying with the saliency of the badge presentation. About Prof. Anderson Ashton Anderson (University of Toronto) is an Assistant Professor of Computer Science at the University of Toronto, where he is also a Faculty Affiliate with the Vector Institute and a Research Fellow in Behavioural Economics. He received his PhD from Stanford University in 2015 and completed a postdoctoral appointment at Microsoft Research NYC in 2017. His research in computational social science focuses on questions in the increasingly vital intersection of data and society. His work has appeared in Proceedings of the National Academy of Sciences, Sociological Science, and The Web Conference.

HCI Reading Group "AI and HCI" 2:30PM Friday October 5 @ DGP Seminar Room
by jritchie＠dgp.toronto.edu 02 Oct '18

02 Oct '18

Hello all, We restart our bi-weekly reading group this week on Friday, October 5 at 2:30 PM. We will be reading a paper called "AI and HCI: Two Fields Divided by a Common Focus", which argues that historically, "AI winters" have corresponded with periods of intense research activity in HCI. The implication is that the two fields have similar goals but opposite approaches, and that as AI falls out of favour, HCI rushes in to fill the gap. Paper link: https://www.aaai.org/ojs/index.php/aimagazine/article/view/2271 I will "champion" the paper by reading it thoroughly and leading the discussion, highlighting why I think the work is important. The meeting will take place in the DGP Seminar Room. Snacks and drinks will be provided! Best, Jacob

HCI Group Meeting on Tuesday, October 2, 2018
by Mohammad Rashidujjaman Rifat 01 Oct '18

01 Oct '18

Hello members, We have our HCI group meeting tomorrow at 12:30 PM at DGP Seminar room. Zhicong Lu is going to give a practice talk of his upcoming IEEE VIS 2018 VAST paper on prewriting. Please drop by and give him feedback. We will use the rest of the time to talk about meeting activities for the upcoming HCI meetings this semester. Lunch will be provided during the meeting. Thanks, Rifat -- Mohammad Rashidujjaman Rifat Ph.D. Student, Department of Computer Science, University of Toronto. http://www.dgp.toronto.edu/~rifat/ Title: InkPlanner: Supporting Prewriting via Intelligent Visual Diagramming Abstract: Prewriting is the process of generating and organizing ideas before drafting a document. Although often overlooked by novice writers and writing tool developers, prewriting is a critical process that improves the quality of a final document. To better understand current prewriting practices, we first conducted interviews with writing learners and experts. Based on the learners’ needs and experts’ recommendations, we then designed and developed InkPlanner, a novel pen and touch visualization tool that allows writers to utilize visual diagramming for ideation during prewriting. InkPlanner further allows writers to sort their ideas into a logical and sequential narrative by using a novel widget— NarrativeLine. Using a NarrativeLine, InkPlanner can automatically generate a document outline to guide later drafting exercises. Inkplanner is powered by machine-generated semantic and structural suggestions that are curated from various texts. To qualitatively review the tool and understand how writers use InkPlanner for prewriting, two writing experts were interviewed and a user study was conducted with university students. The results demonstrated that InkPlanner encouraged writers to generate more diverse ideas and also enabled them to think more strategically about how to organize their ideas for later drafting.
