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.

TUX Member Presentation: Dr. Steven Feiner
*January 15, 2019. Autodesk-MaRS @ 661 University Ave #200, Toronto, ON. *
Lunch reception begins at 12:30 pm. Presentation begins at 1:00 pm.
*User Interfaces for Collaborative AR and VR
*
How can we build 3D user interfaces that help people collaborate more
effectively? I will present research by the Columbia University Computer
Graphics and User Interfaces Lab that explores the design and
implementation of collaborative AR and VR environments. The experimental
systems that I will discuss use different kinds of head-tracked eyewear
and address a wide range of task domains, from remote maintenance
assistance, to urban visualization, to motor rehabilitation. All were
developed with our open-source Mercury Messaging toolkit for Unity
(https://github.com/ColumbiaCGUI/MercuryMessaging), which supports
cross-component communication among scene objects within and between
computers.
