AI Deployments Accelerate Without Sufficient Intelligence: Opportunities for HCI Research

2018-03-27 12:30 at DGP: BCIT, 5th Floor




After 35 years of ups and downs, AI finally achieved in the last two decades triumphs over the world’s best humans in chess, Jeopardy, Go, and poker.  Accelerating advances in deep leaning technology now bring actual or promised deployments in speech and face recognition, judgments of human potential, medical image processing, driverless cars, and automated warfare.  But are these systems truly intelligent?  Replacing simplistic definitions of intelligence with the more nuanced descriptions of Sternberg and Gardner suggests that the answer is “no”.  Thinking about what we should expect of intelligent agents, we must acknowledge the lack of algorithms that can explain the logic behind their actions so that we can understand their behaviour.  This is required so that we can trust them, delegate responsibility for actions and accountability for errors, and expect their decisions that are just.  Removing these limitations will require a healthy dose of HCI research and user experience innovation.  My goal with this talk is to encourage audience members to work on these issues.

Note: Ideas in this lecture are based in part on Chapter 11 of the forthcoming text: Computers and Society: Modern Perspectives, by Ronald M. Baecker, Oxford University Press, 2019.

Upcoming Tux Talk By Ishtiaque Ahmed and Fanny Chevalier on 27th Feb, 2018

Ishtiaque Ahmed and Fanny Chevalier:
“Designing for Voice” and “Make our society think again: Cultivating critical thinking through visualization education”

2018-02-27 12:30 at DGP: BCIT, 5th Floor




Ishtiaque Ahmed


Voice refers to a person’s ability to express their rightful opinions. This has long been a central concern for many sociologists, political scientists, and human- right activists, among others. Voice has also got the attention of the Computer Scientists, especially of some researchers of Human-Computer Interaction (HCI) and Information and Communication Technology and Development (ICTD), in recent years, and various computing systems have been built to help people raise their voices in various contexts. However, the core challenges for designing appropriate computing technologies to support the voices of marginalized communities have mostly been unexplored. In this talk, I will be presenting my work in Bangladesh and India on studying and designing computing technologies for ‘access’, ‘freedom’, ‘infrastructure’, and ‘visibility’ which constitute the idea of ‘voice’. 


Dr. Syed Ishtiaque Ahmed is an Assistant Professor of Computer Science at the University of Toronto. He leads the “Third Space” research group here. He conducts research in the intersection between Human- Computer Interaction (HCI) and Information and Communication Technology and Development (ICTD). He received his PhD from Cornell University in 2017. His PhD research focused on the design challenges around ‘voice’ which he defines through access, autonomy, and accountability. Most of his research is situated in Bangladesh and India, where he has had conducted ethnography and design with many underprivileged communities including readymade garments factory workers, evicted slum dwellers, rickshaw drivers, mobile phone repairers, and victims of sexual harassment. His work often engages with postcolonial computing, infrastructural politics, feminist HCI, and subaltern informatics.

Dr. Ahmed established the first HCI research lab in Bangladesh in 2009. He also launched the first open- source digital map-making initiative in Bangladesh in 2010. Very recently, he and his colleagues started an “Innovation Lab” in Bangladesh to promote grass-root level innovation in Bangladesh. Dr. Ahmed received the prestigious International Fulbright Science and Technology Fellowship in 2011. He also received Intel Science and Technology Center for Social Computing graduate fellowship in 2015. His research has been supported by National Science Foundation of USA, Intel, Microsoft Research, IBM Research, Samsung Research, World Bank, and National Institute of Mental Health of Bangladesh. He also has received multiple awards for his publications including a Best Paper award in ICTD and a Best Paper Honorable Mention Award in ACM CHI.

Data, “the oil of the digital era”, has came to be the most valuable resource of our modern society. As a scientist, I find it exciting to see news outlets using more and more data graphics to communicate facts, stakeholders increasingly rely on data analytics to gain insight into our world and make informed decisions, and governments increasingly promote and engage in open data. In the meantime, it is also daunting to witness how destructive fake news, rumours and falsehoods can be to a general population poorly prepared to engage in evidence-informed reasoning.

In this talk, I will discuss one of the most important societal challenge of our times: data literacy, defined as the ability to understand, find, collect, interpret, visualize, and support arguments using data. Through a sample of my recent research projects focusing on visualization creation, visual communication and visualization education, I will share my reflections on how we can cultivate an informed citizenry capable of critical thinking, reasoning, and knowledge-based decision making.


Fanny Chevalier is an Assistant Professor of Computer Science and Statistical Sciences at University of Toronto, where she conducts research in data visualization and human-computer interaction. In particular, she has been interested in methods and tools that support visual analytics and creative activities, with a primary focus on interactive tools for the visual exploration of rich and complex data, visualization education, the design and perception of animated transitions, and sketch-based interfaces. Before joining UofT, she was a Research Scientist at Inria, France, and post-doctoral researcher at the University of Toronto, Ontario College of Art and Design University (OCAD-U), and Inria-Microsoft joint center in Paris. She obtained her PhD in Computer Science from the Université de Bordeaux. She is the recipient of an Inria grant for scientific excellence (PEDR) and her research papers have received awards at the premier venues in Human-Computer Interaction (ACM CHI, ACM UIST).

Mary Lou Maher:
Designing for Gesture and Tangible Interaction

2018-02-13 12:30 at MaRS




Interactive technology is increasingly integrated with physical objects that do not have a traditional keyboard and mouse style of interaction, and many do not even have a display. These objects require new approaches to interaction design, referred to as post-WIMP (Windows, Icons, Menus, and Pointer) or as embodied interaction design. This presentation provides an overview of the design opportunities and issues associated with two embodied interaction modalities that allow us to leave the traditional keyboard behind: tangible and gesture interaction. The presentation starts with an overview of four design projects which explore the design of tangible interaction with a reconceptualization of the traditional keyboard as a Tangible Keyboard, the design of interactive 3D models as Tangible Models, the design of gesture-base commands for a Walk-up-and-use Information Display, and the design of a gesture-based dialogue for the willful marionette art installation. These projects provide a foundation for design principles for tangible and gesture interaction and a call for research on the cognitive effect of these modalities.


Mary Lou Maher is Professor and Chair of Software and Information Systems at UNC Charlotte. Dr. Maher’s current research interests include: cognitive effects of embodied interaction modalities, computational and cognitive models of creativity and curiosity, and design patterns for active learning strategies in CS education. At UNC Charlotte she has expanded the HCI program to include an undergraduate and graduate concentration in the CS and MSIT degrees, and she has established a Graduate Certificate in HCI. While at the University of Sydney, she created a new undergraduate degree called a Bachelor of Design Computing. While a Program Director at NSF, she started a funding program called CreativeIT.  She is the author or editor of 10 books and over 180 publications. Her most recent book, published in 2017 is Designing for Gesture and Tangible Interaction: http://www.morganclaypoolpublishers.com/catalog_Orig/product_info.php?products_id=1047

Jay Vidyarthi:

The Role of Mindfulness in Design Activism

2018-01-30 12:30 at DGP: BCIT, 5th Floor





In the past few years, we’ve witnessed powerful unintended consequences of modern technology. Researchers and journalists have been publishing about the pitfalls of an attention economy, the internet as an echo chamber, social media’s effects on mental health, a lack of inclusive design, and more. The hype around an internet utopia seems to be fading. As technologists, it’s becoming more important for us to acknowledge how our context, values and perspectives manifest in the ideas, products, systems, and services we create.

I’ve worked as a specialist in user experience and human-computer interaction in a wide range of contexts, including startups, academic research, hospitals, governments, and fortune 500 companies. 7 years ago, I realized that aligning my personal values was the key to my best work, so I quit my job as a UX mercenary and began to specialize in the intersection of mindfulness, mental health, and technology. It is in this space that I’ve not only done my best work, but I’ve also shifted my perspective about the role of human-computer interaction and user experience specialists. 

Design activism is not just a side hustle, it’s part of the job. Good design is not just about usability, engagement and instant gratification. Modern organizations with lofty missions to improve the world rely on researchers and designers to understand context, but it’s up to us to ensure a holistic approach. The commodification of human attention has enabled today’s technologies to covertly influence our identities, our politics, our relationships, and our health. This is why mindfulness – a practice which has been scientifically shown to train attention and help manage mental health – must play a role in shaping the way we design and use technology in the future.


Jay Vidyarthi is an award-winning experience designer and researcher focused on projects related to mindfulness and well-being. He guides teams through a human-centered approach to creating useful products, systems, and services.

Forbes recently named Jay in a list of “10 world renowned meditation tech experts.” He used a lean, iterative process to design Muse: the brain sensing headband, a successful consumer product experience which gives you feedback on your brain while you meditate. His related academic work on a persuasive technology for mindfulness called Sonic Cradle has been published and well-cited in the literature on human-computer interaction. Jay also leads UX projects for major international clients in a wide range of other sectors.

Jay helped launch A Mindful Society – an annual conference which attracts 500+ leaders in healthcare, education, business and government – where he takes a unique design thinking approach to co-create each event directly with the audience.

Data Visualization – Fundamental 21st Century Knowledge

2018-01-16 12:30 at MaRS



I side-stepped into data visualization two decades ago, as an artist trying to answer a series of related questions about IRC chat that had arisen for me as a user and through my dialogues with other users, “Why can’t IRC chat be more dynamic, less linear, relational? How can we manage flaming, lurking and other behaviors that discourage users? What strategies, like play, might resolve conflicts?” Over a number of years I led the creation of the CodeZebraOS which was a playful, non-linear visual chat environment that applied basic affective computing to text analytics. Now a decade later I lead the Visual Analytics Laboratory at OCAD University – a group of researchers who are committed to bringing together visualization design and data analytics.  Times have changed and with them the recognition that big data requires analytics tools to be usable. Visualization systems are built into many software packages and info graphics are everyday fare. The Visual Analytics Laboratory works in partnership with data owners and sources, some with their own analytics capacities, others who rely on the VAL to analyze as well as represent the data.  Over the course of the lecture I will present a glimpse of my early work and provide a history of VAL projects, addressing differing strategies for making meaning from data.  Projects include public displays of data, artistic data presentations, media analytics, urban planning, public data analytics, social media analytics, etc. Researchers in the VAL also raise questions about the use of data and the need for critical literacy regarding data sources and visualizations.


Dr. Sara Diamond is the President of OCAD University, Canada’s, “University of the Imagination”. She holds a PhD in Computing, Information Technology and Engineering, a Masters in Digital Media and Honours Bachelors of Arts in History and Communications. She is an appointee of the Order of Ontario and the Royal Canadian Academy of Artists and a recipient of the Queen’s Diamond Jubilee Medal for service to Canada.  She is the winner of the 2013 GRAND NCE Digital Media Pioneer Award, recognized as one of Toronto Life’s Top Fifty and. she is a Senior Fellow at Massey College, University of Toronto. She was recently honored as one of Canada’s 150 leading women. Since her appointment in 2005 she has led OCAD University’s evolution to a full university, helping to build its transdisciplinary and research-creation research capacity and infrastructure, integrate STEM subjects, create its Digital Futures Initiative, launch the Indigenous Visual Culture Program, strengthen its approach to inclusion, and grow its undergraduate and graduate programs in studio art and design.  Diamond is a researcher in media arts history and policy, visual analytics and has created wearable technologies, mobile experiences and media art. Diamond was honoured with a 1992 retrospective at the National Gallery of Canada, represented Canada in festivals and biennials, and her works reside in collections such as the MoMA in New York City, National Gallery of Canada and Vancouver Art Gallery.

Christopher Collins:
Finding What to Read: Visual Text Analytics Tools and Techniques to Guide Investigation

2017-12-05 12:30 at DGP: BCIT, 5th Floor




Text is one of the most prominent forms of open data available, from social media to legal cases. Text visualizations are often critiqued for not being useful, for being unstructured and presenting data out of context (think: word clouds). I argue that we should not expect them to be a replacement for reading. In this talk I will briefly discuss the close/distant reading debate then focus on where I think text visualization can be useful: hypothesis generation and guiding investigation. Text visualization can help someone form questions about a large text collection, then drill down to investigate through targeted reading of the underlying source texts. Over the past 10 years my research focus has been primarily on creating techniques and systems for text analytics using visualization, across domains as diverse as legal studies, poetics, social media, and automotive safety. I will review several of my past projects with particular attention to the capabilities and limitations of the technologies and tools we used, how we use semantics to structure visualizations, and the importance of providing interactive links to the source materials. In addition, I will discuss the design challenges which, while common across visualization, are particularly important with text (legibility, label fitting, finding appropriate levels of ‘zoom’).


Dr. Christopher Collins is the Canada Research Chair in Linguistic Information Visualization and an Associate Professor of Computer Science at the University of Ontario Institute of Technology (UOIT). His research focus is interdisciplinary, combining information visualization and human-computer interaction with natural language processing to address the challenges of information management and the problems of information overload. His work has been published in many venues including IEEE Transactions on Visualization and Computer Graphics, and has been featured in popular media such as the Toronto Star and the New York Times Magazine. Dr. Collins is a past member of the executive of the IEEE Visualization and Graphics Technical Committee and the IEEE VIS Conference Organizing Committee, and received his PhD in Computer Science from the University of Toronto.

Bill Buxton:
Ubiety: On Design, Place and the Importance of Manners

2017-11-21 12:30 at MaRS



It is a paradox that the better we get at producing useful, affordable, desirable, usable technologies, the more we are confronted by complexity and lack of overall satisfaction. This is partially, or even mainly, due to the demands for economies of scale. Hence, we are deluged by digital do-dads – apps, services and gadgets which on their own may be wonderful, but collectively create an overly complex ecosystem of baubles. What is missed is that the cumulative complexity of enough such baubles crosses the barrier, above which the ecosystem becomes inscrutable. Lying behind this is that things simply do not work together. In a world dominated by “social computing”, there are virtually no social relationships amongst the technologies themselves. Weiser’s label, Ubiquitous Computing, holds. But the result has little or anything to do with what he – or the rest of us on the team – envisioned or intended.

My argument is that he used the wrong word. Ubiquity, i.e, technology everywhere, all the time, etc. is no panacea. Rather, the word that fits far better is Ubiety – a closely related term, but one which has at its core the notion of place. Hence, it points towards the right technology at the right place – extended (in my usage, at least) to encompass place in the physical sense, but also time, social, cultural, temporal, absolute, relative, etc. Furthermore, if we layer the notion of mobility of human action on this framing, what emerges is an enhanced sense of the importance of transitions, and adaptation. This, by way of Piaget, leads us to perhaps a different way of thinking about intelligence – of human and machine – and how intelligent design may pave the way to wrestling the ever-growing complexity to the ground, thus enabling us, and our technologies, to meet our true and worthy potential.


Bill has been walking the path between where people and technology meet for over 40 years – as a designer, musician, lecturer, writer, teacher, critic and researcher. His focus has always been on the human, and his work reflects a particular interest in the creative disciplines. He believes that appropriate design is that which enhances human intelligence and creativity, not replaces it. As a practicing skeptimist, he is a devotee of Melvin Kranzberg’s first law: “Technology is neither good nor bad; nor is it neutral.” His corollary to this is, “Without informed design, it is more likely to lean to the bad than the good.” It is towards becoming thus informed, and enlisting others to do so as well, that both his work, and this talk, are directed.

RBC Research Prize 2017: UofT Faculty and Student Winners


RBC and the University of Toronto recently partnered up to create the RBC Innovation Fellowship program, a joint venture designed to recognize exceptional faculty and graduate students and to provide them with additional resources to advance their research.

The RBC Research Prize 2017 winners come from a variety of disciplines, including Machine Learning and Advanced Data Analytics, Cybersecurity, and User Experience Design/Design Thinking/Human-Machine Interfaces.
This year’s RBC Fellowship Winner is DGP’s own Varun Perumal, a Human-Computer interaction researcher and bonafide hardware engineering fanatic, whose Printem film makes it possible for anyone with a home printer to produce their own electronic circuit boards.
Varun gave RBC a brief overview of his winning proposal in an interview: 

“My research is primarily about creating novel fabrication techniques – the process of making physical things – that will change the future of how we manufacture. Just as 3D printing has made advances in decentralizing and speeding up the production of mechanical products, we’re trying to do something similar for electronics, mainly the components that go into your devices.”




This year’s RBC Research Prize Winners are Gerald Penn and Cosmin Munteanu

The faculty members also gave a brief overview of their winning proposal: 

“One of the interesting challenges we’re facing is that everyone’s jumping on the AI bandwagon, but we don’t have a very good human interface for it yet. In the finance world, for example, high-level financial analysts – these are people who do long-term planning for large investment firms or banks – still use pen and paper. It’s shock from a tech perspective. There’s nothing wrong with it per se, but they’re not benefitting from all these machine learning and NLP advances. The essence of our proposal is to make sure these people can benefit from the technology and to address the problem that the software currently available to support these tasks isn’t designed well for their purposes.”


Full interviews and more details about the winning proposals are available on the RBC Institute for Research website
