UOIT Password Research featured in New York Times and other media

The password security research of vialab researchers Christopher Collins and Rafael Veras, and collaborator Julie Thorpe from the Faculty of Business and Information technology has been featured by Pulitzer-prize winning journalist Ian Urbina in a feature article in the New York Times Magazine.  In his article, “The Secret Life of Passwords“, Urbina investigates the stories behind the passwords we use.  Through the concept of keepsake passwords, the article investigates the evocative stories hidden in passwords. Our research relates to this work in that we have been investigating the numeric and linguistic patterns in passwords, in terms of how these patterns affect security as well as how these patterns reveal the culture and language.

Our research has also been featured in additional media, including:

We have also been featured on UOIT Homepage, including and article entitled “Heartbleed update: UOIT researchers analyze why consumers use weak passwords


vialab @ IEEE VIS 2014

This year four of us are attending IEEE VIS in Paris, France to present work by lab members and collaborators. Lab members are presenting on two papers. DimpVis, by Brittany Kondo and Christopher Collins, presents a new object-centric temporal navigation technique for information visualization. #FluxFlow, by U of Toronto doctoral candidate Jian Zhao and colleagues, including vialab’s Christopher Collins presents a visual analytic system to detecting anomalous patterns in social media. #FluxFlow received an honorable mention for best paper at IEEE VAST.

Lab members are also presenting three posters.  Lexichrome by Chris Kim and Christopher Collins introduces a visualization which reveals the colors evoked by text.  Visitors are invited to upload their own texts to see the chromatic fingerprint. Rafael Veras and Christopher Collins will present an exploration of uneven tree cut models for automatic emphasis and abstraction of visualized hierarchies.  Finally Brittany Kondo, Hrim Mehta, and Christopher Collins will present the IEEE InfoVis best poster winner, Glidgets: interactive glyphs for dynamic graphs.

Christopher Collins was also the co-chair of the IEEE VIS Doctoral Colloquium, a full day event for senior doctoral students to present their research programme and request advice and feedback from distinguished researchers in their field.  Chris also has been leading the redesign of the website for the IEEE Visualization and Graphics Technical Committee, which launched just before the conference.

Congratulations to all the lab members for their hard work and achievements!

Congratulations Brittany Kondo, M.Sc.

Congratulations to Brittany Kondo who successfully defended her M.Sc. thesis. Her work on object-centric temporal navigation for information visualizations featured two major projects, one on time-varying information graphics and one on dynamic graphs. This work will be published in November in both a full paper and a poster at IEEE VIS in Paris. Brittany has been a core member of the vialab for four years, since being hired after third year undergrad as a research assistant.  Brittany is accomplished student, having received support for this research through an NSERC SurfNet Special Projects award, an ICCD Scholarship, an Ontario Graduate Scholarship, and a finalist award for the Google Anita Borg Scholarship.  Brittany leaves the lab to join Oculus Info in Toronto in September.

Tandem Language Learning poster presented at ACM ITS in Scotland

Tabletop Tandem Language Learning

MSc student Erik Paluka recently presented his research on tandem language learning applications for digital tables at the ACM Interactive Tabletops and Surfaces Conference in St. Andrew’s, Scotland.  Erik’s research is designed to facilitate conversation-based language learning between partners who are learning one another’s language through interactive media browsing and collaborative activities.

Dr. Christopher Collins to give Invited Lectures at Duke University

Duke University tower

On April 4-5, Christopher Collins will be visiting Duke University, in Raleigh, NC, USA, to discuss his research interests with colleagues in the Information Science + Information Studies group.  While visiting, he will give two invited lectures, one on linguistic data visualization, and another on visualization techniques for multi-dimensional data.  More details at the Duke University GIS Data blog!

Simple Multi-Touch (SMT) Toolkit

The toolkit source, tutorials, examples, and documentation are available on our github repository. You can also visit the toolkit’s official website at vialab.science.uoit.ca/smt/.

Congratulations Meng-Wei (Daniel) Chang!

Descriptive NPR Lens Widget

Meng-Wei (Daniel) Chang has become the lab’s first graduate!  Daniel completed his M.Sc. thesis defense successfully on Thursday November 22.  His research investigated ways to visualize text through varying rendering techniques on 3D objects.  His SurfNet-funded work touches on text processing, information visualization, scientific visualization, and multitouch application design.  He created a very polished prototype application for exploring a collection of 600,000 car incident reports.  Car part words are extracted from the reports and their occurrence counts are visualized on a 3D model of a car, so that parts which are mentioned more often in failure reports stand out in the 3D view.  Interactive widgets support exploration of the data across time, across various car models, and co-occurrence relationships between parts.  This visualization technique could be used to visualize product reviews, hotel reviews, or any sort of text which mentions parts of a scene or of an object which can be rendered using non-photorealistic techniques.
