Colloquium Talk with Dr. Colin M. Gray, Associate Professor & Director of the HCI/d Program at Indiana University Bloomington, April 21: “Deceptive Design and the Growing Threat of ‘Dark Patterns’ in Technology Practices”

Dr. Colin M. Gray (they/them), Associate Professor and Director of the Human-Computer Interaction design (HCI/d) program at Indiana University Bloomington, will give a colloquium talk, titled “Deceptive Design and the Growing Threat of ‘Dark Patterns’ in Technology Practices” on Tuesday, April 21, in Science Complex P101 from 12:30 – 1:30 PM.

See below for more information about our speaker.

Abstract:    The strategic goals of organizations increasingly consider the role of user experience, impacting both the design of user interfaces as well as the relationships of humans and society to technology. But while knowledge of user needs and human psychology is generally framed as a means of generating empathy or reducing the divide between humans and technology, this knowledge also has the potential to be used for nefarious purposes.

In this talk, I share findings from over five years of my work on dark patterns that addresses practitioners’ engagement with issues of ethical concern. I use the concept of “dark patterns” as a point of connection to identify emerging synergies among design, computer science, ethics, law, and policy. I start with a collection of examples of dark patterns and “asshole designs,” demonstrating the harmful use of manipulative patterns that are ubiquitous—and increasingly under legal scrutiny. I then describe the organizational and disciplinary complexities that make it difficult for practitioners to act in ethically responsible ways. I conclude by describing the potential impact of regulations and enhanced organizational practices in responding to these threats. I use these studies to build a case for ethical engagement in the education and practice of designers and technologists, pointing towards the need for scholars and educators to address both near-term issues such as manipulation, and longer-term issues that relate to social impact, responsibility, and the potential for regulation.

Speaker Bio:   Colin M. Gray is an Associate Professor in the Luddy School of Informatics, Computing, and Engineering at Indiana University Bloomington, where they are Director of the Human-Computer Interaction design (HCI/d) program. They hold appointments as Guest Professor at Beijing Normal University and Visiting Researcher at Northumbria University.

Colin holds a PhD in Instructional Systems Technology from Indiana University Bloomington, a MEd in Educational Technology from University of South Carolina, and a MA in Graphic Design from Savannah College of Art & Design. They have worked as an art director, contract designer, and trainer, and their involvement in design work informs their research on design activity and how design capability is learned. Colin’s research focuses on the ways in which the pedagogy and practice of designers informs the development of design ability, particularly in relation to ethics, dark patterns, design knowledge, and learning experience. They have consulted on multiple legal cases relating to dark patterns and data protection and work with regulatory bodies and non-profit organizations to increase awareness and action relating to deceptive and manipulative design practices. Colin has co-authored or edited four books and over 150 journal articles, conference papers, and book chapters spanning multiple disciplines, including human-computer interaction, instructional design and technology, law and policy, design theory and education, and engineering and technology education.

Colloquium Talk with Mr. Rodrigo Domingues, VP of Engineering at CI&T, March 6: “From Code to Intelligence: Software Engineering in the Age of AI”

Mr. Rodrigo Domingues, VP of Engineering at CI&T, will give a colloquium talk, titled “From Code to Intelligence: Software Engineering in the Age of AI” on Friday, March 6, in Science Complex P101 from 12:30 – 1:30 PM.

See below for more information about our speaker.

Abstract: AI is changing how software is built, and with it, the role of the engineer. Modern systems are no longer just collections of functions and services — they increasingly include models, agents, feedback loops, and new forms of observability. In this talk, I’ll introduce the core ideas behind AI engineering, from foundational concepts to how real-world AI systems are designed and operated. I will discuss how agent based architectures differ from traditional software, why observability and evaluation are critical, and what engineers need to think about when building systems that reason and act. Rather than replacing engineers, AI is creating a new way of solving problems — one that demands stronger system thinking, better judgment, and deeper technical understanding. This session offers students a practical and optimistic view of what it means to build software in the age of AI.

Speaker Bio: Rodrigo Domingues is a technology leader and software engineer with extensive experience designing and building large-scale systems. He has worked across engineering, architecture, and leadership roles, helping teams deliver complex digital products and platforms.

See below for more information about our speaker.

Abstract: The use of interactive technologies is changing the way our cognitive processes work: from perception to memory, attention, learning, problem solving, communication, and metacognition. In fact, we may be seeing the beginnings of one of the largest shifts in cognition brought about by technology, perhaps even bigger than the changes brought by handwriting and mathematical notation. The problem is that we have largely been reactive. For the most part, technology designers develop what the market calls for without a holistic view of how all these technologies may affect how we think and how we interact with each other. The good news is that we have choices and we can have visions. What do we want the cognitive future to be like? If we can give people cognitive superpowers through technology, what should those be? In this talk, Juan Pablo Hourcade will provide an analysis of how current and upcoming changes in interactive technologies are affecting and may further affect cognitive processes. This will be followed by a discussion of guiding principles to optimally affect cognitive processes.

Speaker Bio: Dr. Juan Pablo Hourcade is a Professor at The University of Iowa’s Department of Computer Science and Director of Graduate Studies for the Interdisciplinary Graduate Program in Informatics. His main area of research is Human-Computer Interaction, with a focus on the design, implementation and evaluation of technologies that support creativity, collaboration, well-being, healthy development, and information access for a variety of users, including children and older adults.

CS Alumni Speed Networking Event

The Computer Science Department held its first CS Alumni Speed Networking event on March 25, 2025.  Students were invited to introduce themselves and ask questions to learn about the careers of our alumni. Twenty one alumni connected with the students to discuss their career path and to offer professional advice. Each student completed five individual meetings with alumni.  Student participants shared their feedback on the event:

  • It was awesome. I learned a lot from each alumni and they gave me great advice that encouraged me. I will use this advice to motivate me and give me a better understanding of what I can prepare for in the future.
  • I was able to openly communicate about current trends in tech, the job market, what to expect in industry as well as solid advice for early career students like myself.
  • [One] take-away was the ability to start networking and meeting people who are in industries that I’m interested in.
  • I really enjoyed getting to talk to the alumni group, it definitely gave me a lot of insight into what the future might hold! 

    One key takeaway for me is how each alumni I talked to followed a different path to get to where they were. I found it very helpful to see all the branching paths and applications that CS was able to provide to the alumni. I felt it expanded my view and showed me different possibilities of career choices and special interests that I didn’t even know existed.

  • Always keep your options open, and never get too comfortable in one spot because you never know the opportunities that may present itself down the road.
  • Thank you for the opportunity last night to meet with TCNJ alumni. It was fantastic meeting everyone and I thank them for providing their input on the questions I had. 

The CS Alumni Speed Networking event was open to sophomores through senior majors.  It was organized and hosted by Dr. Deborah Knox.

Colloquium Talk with Dr. Ricardo Baeza-Yates, ACM Distinguished Speaker, March 7: “Responsible AI”

Dr. Ricardo Baeza-Yates, ACM Distinguished Speaker, will give a virtual colloquium presentation, titled “Responsible AI” on Friday, March 7, which will be streamed in Science Complex P101 from 12:30 – 1:30 PM.

See below for more information about our speaker.

Abstract:  In the first part we cover five current specific problems that motivate the needs of responsible AI: (1) discrimination (e.g., facial recognition, justice, sharing economy, language models); (2) phrenology (e.g., biometric based predictions); (3) unfair digital commerce (e.g., exposure and popularity bias); (4) stupid models (e.g., minimal adversarial AI) and (5) indiscriminate use of computing resources (e.g., large language models). These examples do have a personal bias but set the context for the second part where we address four challenges: (1) too many principles (e.g., principles vs. techniques), (2) cultural differences; (3) regulation and (4) our cognitive biases. We finish discussing what we can do to address these challenges in the near future to be able to develop responsible AI, particularly under the umbrella of the incoming regulation (European Union’s AI Act & White House’s Blueprint for an AI Bill of Rights).

Dr. Salgian to Give Talk “Follow the Beat: Analyzing and Generating Conducting Gestures Using Computers”

Dr. Andrea Salgian will give a guest talk at the February 2025 joint meeting of the Princeton ACM & IEEE-CS chapters on Thursday, February 20 in STEM 102.  The event is open to the public and light refreshments and networking will begin at 7:30 PM, with the formal talk beginning at 8:00 PM.

Dr. Salgian’s talk is titled “Follow the Beat: Analyzing and Generating Confucting Gestures Using Computers”.  An abstract of her talk can be found below.

Abstract: Musical conducting is a unique blend of musical performance and communication. Conductors are the only musicians who can freely move their hands to create sound, without having their gestures constrained by a rigid instrument, as their instrument is the entire orchestra. The act of conducting can also be seen as communication, as the conductor is using gestures to convey information to the other musicians.

While gesture recognition is a widely researched topic in human-computer interaction, conducting hasn’t been studied too extensively. In this talk I will present some of my work on analyzing, generating, and recognizing
conducting gestures, highlighting both methods and applications.
