Scanning Between Graph Visualizations: An Eye Tracking Evaluation Research Paper will be discussed as part of the two day BELIV'10: BEyond time and errors: novel evaLuation methods for Information Visualization workshop

Presenters: Joe Goldberg and Jonathan Helfman, Applications User Experience, Oracle

The purpose of information visualization is to provide users with accurate visual representations of data and natural interaction tools to support discovery and sense making. These activities are often exploratory in nature and can take place over days, weeks or months and rarely follow a predefined or linear workflow. While the overall use of information visualizations is accelerating, the growth of techniques for the evaluation of these systems has been slow. To understand these complex behaviors, evaluation efforts should be targeted at the component level, the system level, and the work environment level. The commonly used evaluation metrics such as task time completion and number of errors appear insufficient to quantify the quality of an information visualization system; thus the name of the workshop: “beyond time and errors …”.

BELIV 2010 aims at gathering researchers in the field to continue the exploration of novel evaluation methods, and to structure the knowledge on evaluation in information visualization around a schema, where researchers can easily identify unsolved problems and research gaps.

Date: Saturday, April 10 - Sunday, April 11, 2010
Time: 2-day workshop
Location: TBD




The research paper “Using a Distributed Heuristic Evaluation to Improve the Usability of Open Source Software” will be discussed as part of the workshop “The Future of FLOSS in CHI Research and Practice”

Daniel Schwartz

Presenters: Daniel Schwartz, Senior Interaction Designer, Applications User Experience, Oracle; Alex Faaborg, Principal Designer, Mozilla

As the usage and impact of Free/Libre/Open Source Software (FLOSS) has grown immensely over the past decade in business, education, government, and research, so has the need for an optimal user experience for FLOSS. In our paper, we will explore how building tools to enable a large scale distributed Heuristic Evaluation of usability issues can potentially reshape how FLOSS communities view usability, and educate a new generation of user experience designers. Integrating such tools directly into the software may have the deepest impact, with the hopes of building a culture around human-computer interaction principles that will cross-pollinate to other FLOSS projects. The workshop itself will bring together a diverse group of researchers and practitioners from the FLOSS and CHI communities to establish a concrete research agenda for studying the FLOSS community, developing tools and methods for the community, and collaborating to solve shared problems.

Date: Sunday, April 11, 2010
Time: 1-day Workshop (9:00 AM - 6:00 PM)
Location: Hyatt Regency Atlanta, Centennial Ballroom 1




What Makes a Good Design Critic? Food Design vs. Product Design Criticism

Patañjali Venkatacharya
Patañjali Venkatacharya

Presenters: Patanjali Venkatacharya, Chief Evangelist, Apps UX, Oracle, Food Architect, Patanjali’s Kitchen LLC; Jonathan Kessler, Food Critic & Writer, Atlanta Journal-Constitution; Tami Hardeman, Food Stylist, Atlanta, GA; Ed Seiber (Restaurant Architect & Designer, Atlanta, GA

This panel will bring together leading food design and product design critics. The panelists will include: a leading Atlanta-based food critic and writer, a food stylist, a restaurant architect & designer, and a well-known product design critic familiar with the field of user experience.  Together, the panel will compare and contrast how design experts from these two disciplines provide design criticism, and whether there are any novel learning points from each perspective.

Date: Monday, April 12, 2010
Time: 4:30 - 6:00 PM PT
Location: TBD




SIG: Branding the Changing Enterprise - Impact of Mergers & Acquisitions on User Experience Organizations

Presenters: Team Oracle: Anna Wichansky & Madhuri Kolhatkar: Team SAP: Dan Rosenberg, Michael Arent; Team CA: Roman Longoria, Bob Hendrich. Moderator: Janaki Kumar, SAP. Discussant: Arnie Lund, Microsoft

Mergers and acquisitions are becoming increasingly common in the enterprise software world. For example, SAP acquired Business Objects, Oracle acquired PeopleSoft and CA acquired Cassatt in recent times. While this is a business expansion strategy for the acquiring company, it presents a challenge for UX professionals in both the acquiring and acquired companies, who are responsible for branding the look and feel of the newly combined business entity. This Special Interest Group examines the design, technical and cultural challenges facing a UX practitioner from the acquiring as well as acquired company’s perspectives. We will explore possible best practice solutions that can help other UX professionals facing similar challenges.

Date: Tuesday, April 13, 2010
Time: 11:30 AM - 1:00 PM

Average Task Times in Usability Tests: What to Report?

Jeff Sauro

Presenters: Jeff Sauro

The distribution of task time data in usability studies is positively skewed. Practitioners who are aware of this positive skew tend to report the sample median. Monte Carlo simulations using data from 61 large-sample usability tasks showed that the sample median is a biased estimate of the population median. Using the geometric mean to estimate the center of the population will, on average, have 13% less error and 22% less bias than the sample median. Other estimates of the population center (trimmed, harmonic and Winsorized means) had worse performance than the sample median
