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.

DGP-HCI Meeting on Tuesday, Nov 27, 2018 @ DGP
by Mohammad Rashidujjaman Rifat 27 Nov '18

27 Nov '18

Hello all, We are hosting Prof. Géry Casiez in our next HCI meeting on Tuesday, November 27, 2018, at 12:30 pm at DGP Seminar room. Details about the talk are below. Lunch will be provided during the meeting. Title: The measure and compensation of latency in touch and mouse-based systems Abstract: Any interactive system exhibits some delay between a user’s action and the corresponding system response, known as the end-to-end latency. Users can perceive touchscreen latency as low as 2 ms and performance degrades above 25 ms. In indirect interaction, it has been shown that latencies above 50 ms affect performance. Yet, the latency of current systems is above these thresholds of perception and performance. How can we simply measure the latency of current touch systems and mouse-based interfaces to know how performance is affected? How can we determine where it comes from to try to reduce it? Can we compensate some of the latency using trajectory prediction without introducing side-effects caused by next-point prediction techniques? Bio: Géry Casiez is a Professor of Computer Science at the University of Lille (Science and Technology) and member of Inria Lille. In 2018, he has been appointed junior member of the Institut Universitaire de France for 5 years. His research interests include input devices and interaction techniques, transfer functions, system responsiveness, and hardware fabrication. He is the co-author of more than 30 papers published at CHI and UIST and he regularly serves in the program committees of these conferences. Géry Casiez was president of the Association Franco-phone de l’Interaction Homme-Machine (AFIHM) from 2014 to 2017. He received his Ph.D. degree at the University of Lille in 2004.

He is available for meetings/demos the rest of the day, so please do sign up. I've asked Jiannan Li to coordinate his meeting/demo schedule, so respond to the msg he will send out soon. Thanks Ravin Title Wearable Interactions Using Touch without a Touchscreen Abstract The ubiquitous touchscreen has become the primary mechanism with which users interact with small personal computing devices. While there is a trend showing that personal computing devices may become smaller and smaller, a primary constraint on device miniaturization is the user interface (e.g. touchscreen). Screens need to be large enough to be seen, and keyboards need enough physical space to facilitate typing. Arbitrary hardware miniaturization may lead to devices that are not usable. In this talk, I will motivate and present two sensing techniques that enables touch as an input mechanism on wearable devices without the need of a touchscreen. I will also present a haptic technique that enables touch as an output mechanism to create a unique mixed reality experience for games and videos on smartwatches. The long-term goal of this research is to develop interaction modalities that that are easy, intuitive, and efficient for interacting with small wearable devices.

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.
