Drexel CCI Researchers Present at 2020 ACM CHI International Conference on Human Factors in Computing Systems

On April 25-30, several Drexel College of Computing & Informatics (CCI) faculty members, PhD in information science students and alumni presented at the virtual ACM CHI Conference on Human Factors in Computing Systems (CHI 2020).

Drexel CCI is home to research labs and academic programs specializing in the human-computer interaction field. In fall 2019, the College launched a Master of Science in Information program including a graduate major in Human-Computer Interaction & User Experience, as well as a graduate minor and Graduate Certificate in Human-Computer Interaction & User Experience.

The ACM CHI Conference on Human Factors in Computing Systems is the premier international conference of Human-Computer Interaction. CHI – pronounced ‘kai’ – is a place where researchers and practitioners gather from across the world to discuss the latest in interactive technology.

The following Drexel University faculty, students and alumni participated in the virtual CHI 2020 conference: 

  • Paper (Receiving Honorable Mention): The Politics of Privacy Theories: Moving from Norms to Vulnerabilities

Authors: Nora McDonald, PhD information science ’19 and Associate Professor and Director of the MS in Information Program Andrea Forte, PhD

ABSTRACT: Privacy and surveillance are central features of public discourse around use of computing systems. As the systems we design and study are increasingly used and regulated as potential instruments of surveillance, HCI researchers—even those whose focus is not privacy—find themselves needing to understand privacy in their work. Concepts like contextual integrity and boundary regulation have become touchstones for thinking about privacy in HCI. In this paper, we draw on HCI and privacy literature to understand the limitations of commonly used theories and examine their assumptions, politics, strengths, and weaknesses. We use a case study from the HCI literature to illustrate conceptual gaps in existing frameworks where privacy requirements can fall through. Finally, we advocate vulnerability as a core concept for privacy theorizing and examine how feminist, queer-Marxist, and intersectional thinking may augment our existing repertoire of privacy theories to create a more inclusive scholarship and design practice. 

  • Paper: Checklist Design Reconsidered: Understanding Checklist Compliance and Timing of Interactions

ABSTRACT: We examine the association between user interactions with a checklist and task performance in a time-critical medical setting. By comparing 98 logs from a digital checklist for trauma resuscitation with activity logs generated by video review, we identified three non-compliant checklist use behaviors: failure to check items for completed tasks, falsely checking items when tasks were not performed, and inaccurately checking items for incomplete tasks. Using video review, we found that user perceptions of task completion were often misaligned with clinical practices that guided activity coding, thereby contributing to non-compliant check-offs. Our analysis of associations between different contexts and the timing of check-offs showed longer delays when (1) checklist users were absent during patient arrival, (2) patients had penetrating injuries, and (3) resuscitations were assigned to the highest acuity. We discuss opportunities for reconsidering checklist designs to reduce non-compliant checklist use. 

  • Paper: Engaging with Public Art: An Exploration of the Design Space

Author: Assistant Teaching Professor Tim Gorichanaz, PhD

ABSTRACT: At its best, public art can promote moral learning in individuals and societies, and digital technology can help achieve this value. As a first step in creating such systems, this paper presents a probe study exploring the design space of reflective engagement with public art. The probe took the form of a mural journal, which was distributed to participants in Philadelphia. The findings show how public art journaling can be integrated into one's life, both logistically and psychologically, and the value of art journaling for introspection, cultivating attention and having fun. This study surfaces a number of tensions in the design space that designers must navigate, such as the question of reflecting with public art on site (now) versus at home (later). This work provides designers with the grounds for informed inspiration to ideate systems that deepen people's experiences with public art. 

  • Late-Breaking Work: Understanding Digital Checklist Use Through Team Communication

Authors:  PhD information science students Angela Mastrianni, Leah Kulp, Emily Mapelli and Associate Professor Aleksandra Sarcevic, PhD

ABSTRACT: Introducing technology support in a complex, team-based work setting requires a study of teamwork effects on technology use. In this paper, we present our initial analysis of team communications in a trauma resuscitation setting, where we deployed a digital checklist to support trauma team leaders in guiding patient care. By analyzing speech transcripts, checklist interaction logs, and videos of 15 resuscitations, we identified several tensions that arose from the use of a checklist in a team-based process with multi-step tasks. The tensions included incorrect markings of in-progress tasks as completed, failure to mark completed tasks due to missed communications, failure to record planned tasks, and difficulties in recording dynamic values. From these findings, we discuss design implications for checklist design for dynamic, team-based activities.
