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 to Rafael and Brittany!

Congratulations to vialab members Rafael Veras Guimarães and Brittany Kondo who have been awarded the Italian Cultural Centre of Durham scholarship for PhD studies ($5,000) and MSc studies ($3,000) respectively.  Support such as these awards from the ICCD will help these exemplary students complete their studies.  Brittany’s research into new ways to interact with time-varying datasets using touch screens and Rafael’s research into analyzing the language of passwords to enhance computer security will certainly have an important impact on the way we interact with information and computer systems in the future. We are all very grateful to the ICCD for their forward-thinking support of students and research at UOIT.

Congratulations Rafael Veras Guimarães!

Password Lexicon: Parallel Coordinates Plot

Chris, Rafael, and JulieRafael Veras Guimarães successfully defended his M.Sc. thesis “An Investigation of Semantic Patterns in Passwords”.  His research investigated semantic patterns in passwords, including published work on dates in passwords, and exciting forthcoming work on the secret language of passwords.  In each case, Rafael used visualization and natural language processing techniques to parse millions of leaked and cracked real passwords and organize the data.  Patterns discovered in the password data, such as word-word dependencies (“goodgirl”>>”goodboy” but “badboy”>>”badgirl”) revealed vulnerabilities that semantic patterns present to passwords as a way to secure information.  His research has resulted in a new method for semantics-based password cracking attacks, and will surely motivate changes to password creation mechanisms and policies in the future.

As this work is in submission, and we have exciting future work plans, we have not posted his thesis or latest results, but hope to do so soon!

Rafael plans to stay for future studies at UOIT as a PhD candidate, and we are excited to continue to work with him.
