Logging Interactive Visualizations
&
Visualizing Interaction Logs

This workshop takes place at the beginning of the upcoming IEEE VIS 2016 conference (23-28 October 2016, Baltimore, MD, USA), which is the premier venue for visualization. The workshop is open to anyone who previously registered at the conference. This website is still in progress, please come back frequently to get updates (and see recent changes here) or contact us directly.

Keynote

"Visualizing and manipulating temporal event sequences with EventFlow: challenges and lessons learned for log analysis."

Speaker: Catherine Plaisant, Human-Computer Interaction Lab, University of Maryland.

Abstract: The Human-Computer Interaction Lab has developed tools such as EventFlow and Coco for event sequence analytics, which help analysts explore aggregated visual representations, search for specific patterns, compare groups of records, and interactively model the data to answer users’ specific questions. Through demonstrations I will quickly review the design elements that were most useful for log analysis and discuss challenges we encountered.

Bio: Catherine Plaisant is a Senior Research Scientist at the University of Maryland Institute for Advanced Computer Studies and Associate Director of Research of the Human-Computer Interaction Lab. Catherine Plaisant has over 140 published papers, on subjects as diverse as information visualization, medical informatics, universal access, digital humanities, technology for families, and evaluation methodologies. With Ben Shneiderman she co-authored the 4th, 5th and 6th Editions of Designing the User Interface, one of the major books on Human-Computer Interaction.

Workshop Informations

This workshop addresses the following issues:

The workshop will be organized as follows:

The program may evolve depending on the number of submissions, but our goal is to allow as many people as possible to expose their point of view on this important topic. We invite IEEE Vis participants to contribute to this workshop in order to achieve the following goals:

Defining Logging Strategies

The first step when setting up a logging process is to ask what should be recorded, when it should be recorded, and how (by the web server, by the application itself, etc.). For example, even a simple and ubiquitous interaction, like a mouse dragging, requires carefully considerations as it can generate a lot of noisy events resulting in very large and thus difficult to interpret log files.

Logging Infrastructure

As we have mentioned earlier, a series of tools log users by default (e.g. proxies, web servers). However, from the authors' practical experience, it is oftentimes necessary to build its own tools for the sake of control over the logging format and flexibility in types of events to tracks.

Making sense of logs: Analysis and Reporting

Logs reporting in academic papers varies with high discrepancies. This raises the need to improve logs analysis reporting to allow sound conclusions, and reproducibility of the evaluation.

Legal and Ethical questions

As log collection and analysis is related to behavioral research involving humans, it requires approval from researchers' employer.

Application Related to Logging

Finally, we think that agreeing upon a logging format and infrastructure, would have spillovers such as data interoperability and allow more applications building upon logs. Letting users visualize logs, whether it is their own or others, is a rich and promising area to identify patterns, insights of large logs collections. Logs may also enrich the user experience with enhanced history navigation, browsing and monitoring. More Infovis and Visual Analytics application already make sense of logs and we expect the workshop to discuss challenges (data type, user tasks, scalability, etc.) coming with those types of visualizations.
