Twidale promotes usability for everyone, everywhere

According to Professor Michael Twidale, bad usability can be an irritation for everyone but "especially awful" for the underprivileged. In "Everyone Everywhere: A Distributed and Embedded Paradigm for Usability," which was recently published in the Journal of the Association for Information Science and Technology (JASIST), Twidale and coauthors David M. Nichols (University of Waikato, New Zealand) and Christopher P. Lueg (Bern University of Applied Sciences, Switzerland) present a new paradigm to address the persistence of difficulties that people have in accessing and using information.

Twidale points to the COVID vaccination rollout as one recent example of bad usability. In many places, people have to book their vaccine appointments online, which can be difficult for the especially vulnerable elderly population.

"When hard to use software means a vulnerable elderly person cannot book a vaccination, that’s a social justice issue," he said. "If you can't get things to work, it can further exclude you from the benefits that technology is bringing to everyone else. Making a computer system easier to use is a tiny fraction of the cost of making the computer system work at all. So why aren't things fixed? Because people put up with bad interfaces and blame themselves. We want to say, 'No, it's not your fault! It is bad design.'"

Twidale and his coauthors propose expanding awareness of usability and distributing the topic across disciplines, beyond the "tiny elite" of usability professions. In turn, this increased emphasis on usability could lead to improvements in other disciplines such as politics (e.g., better ballot design) and medicine (e.g., user-friendly medical devices).

"A wider usability movement would remind members of any profession that regardless of their domain and efforts in making the world a better place, bad usability makes everything worse. In contrast, reducing bad usability is often a relatively low-cost way of contributing to improvements within these professions."

Twidale holds a PhD in computing from Lancaster University. He is an expert in computer-supported cooperative work, collaborative technologies in digital libraries and museums, user interface design and evaluation, information visualization, and museum informatics. He holds joint appointments at Illinois in the Department of Computer Science, Information Trust Institute, and Academy of Entrepreneurial Leadership.

New study shows LLMs respond differently based on user’s motivation

A new study conducted by PhD student Michelle Bak and Assistant Professor Jessie Chin, which was recently published in the Journal of the American Medical Informatics Association (JAMIA), reveals how large language models (LLMs) respond to different motivational states. In their evaluation of three LLM-based generative conversational agents (GAs)—ChatGPT, Google Bard, and Llama 2—the researchers found that while GAs are able to identify users' motivation states and provide relevant information when individuals have established goals, they are less likely to provide guidance when the users are hesitant or ambivalent about changing their behavior.
