We look forward to seeing you there! Ali, Daniel, and Tovi TUX Member Presentation: Prof. Ashton Anderson *October 5, 2018. DGP Lab, Department of Computer Science at U of T @ 40 St. George Street Room 5166* Lunch reception begins at 12:30 pm. Presentation begins at 1:00 pm. *The Design of Social Incentives * 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. *Bio* 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.

21 Nov '18

Dear TUX Community, Id like to invite you to an HCI poster showcase that the students in the Human-Computer Interaction course I am teaching at U of T will be participating in tomorrow. The course is cross listed as a fourth-year undergraduate / graduate course. For their final term project, they have been conducting a literature review and proposing new ideas on an HCI topic of choice. Tomorrow they will be presenting their findings in the format of a poster. The poster showcase will be held in the Autodesk space on the ground floor of the MaRS building. You are welcome to come by and see the posters and meet the undergraduate and graduate students that have been studying HCI at U of T this semester. Date: Thursday, November 22 Time: 2pm-4pm Location: Autodesk-MaRS Hope to see you there! Thanks, Tovi

A reminder that tomorrow we have a Sanders Series Invited Lecture by Prof. Regan Mandryk. We look forward to seeing you there! Ali, Daniel, and Tovi Sanders Series Invited Lecture: Prof. Regan Mandryk *November 20, 2018. Autodesk MaRS IDEaS Lab @ 661 University Ave., Ground Floor* Lunch reception begins at 12:30 pm. Presentation begins at 1:00 pm. *Fun Science: The Paradox of Conducting Scientific Research in the Context of Digital Social Play * Games have long been used to support social interaction and create shared experiences that draw us closer together. Digital games are increasingly being used to form and maintain relationships and researchers have been investigating the role that social games play in satisfying our need for relating to others. However, games researchers must balance the tradeoff between using experimental rigor to control the environment for internal validity with the external validity of having participants feel like they are engaging in play with friends under their own volition, rather than participating in an experiment. In this talk, Mandryk will present her perspective on trying to reconcile the fundamental incompatibility of doing controlled scientific experiments in the context of social play. Drawing from 15 years of experience, she will share what works, what doesn’t, and what she hopes to see in the future. *Bio* Regan Mandryk is a professor in Computer Science at the University of Saskatchewan; she pioneered the area of physiological evaluation for computer games in her award-winning Ph.D. research at Simon Fraser University with support from Electronic Arts. With over 200 publications that have been cited thousands of times (including one of Google Scholar’s 10 classic papers in HCI from 2006), she continues to investigate novel ways of understanding players and their experiences, but also develops and evaluates games for health and wellbeing, and games that foster interpersonal relationships. Regan has been the invited keynote speaker at several international game conferences, led Games research in the Canadian GRAND Network, organizes international conferences including the inaugural CHI PLAY, the inaugural CHI Games Subcommittee, and CHI 2018, and leads the first ever Canadian graduate training program on games user research (SWaGUR.ca) with $2.5 million of support from NSERC. She was inducted into the Royal Society of Canada’s College of New Scholars, Artists and Scientists in 2014, received the University of Saskatchewan New Researcher Award in 2015, the Canadian Association for Computer Science’s Outstanding Young Canadian Computer Science Researcher Prize in 2016, and the prestigious E.W.R. Steacie Fellowship in 2018. cid:image009.png@01D357B6.5B82A7B0 *OUR SPONSORS:* cid:image010.png@01D357B6.5B82A7B0 *TUX is made possible by the support of our sponsors, Steven Sanders, Autodesk, * *University of Toronto Department of Computer Science, and MaRS*. */About MaRS:/*/MaRS is the one of the world’s largest urban innovation hubs—a place for collaboration, creativity and entrepreneurship.

[cid:image005.png@01D357B6.5B82A7B0] [cid:image008.png@01D10810.C2D01210] [cid:image008.png@01D357B6.5B82A7B0] Dear Tux, A reminder that our next Member Presentation will take place tomorrow (Tuesday) at the DGP lab (40 St. George St., 5th Floor). We have two exciting speakers; looking forward to seeing you there! Haijun Xia [http://www.tux-hci.org/wp-content/uploads/2018/11/haijunxia-223x300.jpg]<http://www.tux-hci.org/wp-content/uploads/2018/11/haijunxia.jpg> Abstract Supporting Direct Human-Computer Communication Abstract: From the dawn of digital computing, we have striven to communicate with computers to fully leverage their computing power. The development of sensing technologies enables such communication with verbal language, gestural language, and graphical language. Despite the many different input techniques, conversations with computers are all structured around a fixed sets UI elements that do not support much flexibility. As such, the rich and dynamic thoughts we could have articulated naturally with flexible words, gestures, and visuals must be formalized as structured, restrictive, rigid, and repetitive tasks around such element. I seek to design a new interaction language that enables us to directly and flexibly articulate our creative thoughts. I approach this from two directions. First, I design new graphical representations of digital content to match our dynamic and flexible needs. Second, I invent novel interaction techniques to enable the direct articulation of user intention. Bio I am a PhD student advised by Prof. Daniel Wigdor at DGP lab, University of Toronto. I am also a Microsoft PhD Fellow and Adobe PhD Fellow. My research area is Human-Computer Interaction, in which I focus on creating flexible digital media to augment our creativity. I approach this from two directions: 1) I invent novel representation of the abstract content to match our dynamic needs; and 2) I develop novel interaction techniques that allow us to express our thoughts and ideas via graphical, gestural, and vocal communication that we are all naturally capable of.

When we manipulate physical objects, we also understand the status of the object and control the posture or the forces by what we feel from our fingers. This rich physical interaction enables eyes-free and skillful object manipulation. However, most touch interfaces ignore this rich source of information and only register the contact location of a finger and do not give any physical reactions to our touch. This limited bandwidth of input and output channel often necessitates the use of multiple input modes and many buttons and makes eyes-free interaction challenging. In this talk, I will introduce projects that my colleagues and I have worked on to enrich our touch interaction with computers by utilizing previously unused physical properties of our touch. I will discuss how we can make the computers to sense more from our touch and use such information to make the richer interaction and also our haptic feedback methods that could enable virtual contents to be felt. Bio Seongkook is a postdoctoral fellow in the DGP Lab at the University of Toronto working with Prof. Daniel Wigdor. He received his Ph. D. in Computer Science at KAIST in 2017, under the supervision of Prof. Geehyuk Lee. He is interested in making communication between human and computers richer and more natural through the better use of new input and output modalities. His work has been published in premier conference proceedings and journals, such as CHI, UIST, CSCW, and IEEE Trans. Haptics.
