Virtual reality training tool helps nurses learn patient-centered care

Apr 7, 2025

University of Delaware computer science students have developed a digital interface as a two-way system that can help nurse trainees build their communication skills and learn to provide patient-centered care across a variety of situations. This virtual reality training tool would enable users to rehearse their bedside manner with expectant mothers before ever encountering a pregnant patient in person.


The digital platform was created by students in Assistant Professor Leila Barmaki’s Human-Computer Interaction Laboratory, including senior Rana Tuncer, a computer science major, and sophomore Gael Lucero-Palacios.


Lucero-Palacios said the training helps aspiring nurses practice more difficult and sensitive conversations they might have with patients.


"Our tool is targeted to midwifery patients,” Lucero-Palacios said. “Learners can practice these conversations in a safe environment. It’s multilingual, too. We currently offer English or Turkish, and we’re working on a Spanish demo.”


This type of judgement-free rehearsal environment has the potential to remove language barriers to care, with the ability to change the language capabilities of an avatar. For instance, the idea is that on one interface the “practitioner” could speak in one language, but it would be heard on the other interface in the patient’s native language. The patient avatar also can be customized to resemble different health stages and populations to provide learners a varied experience.


Last December, Tuncer took the project on the road, piloting the virtual reality training program for faculty members in the Department of Midwifery at Ankara University in Ankara, Turkey. With technical support provided by Lucero-Palacios back in the United States, she was able to run a demo with the Ankara team, showcasing the UD-developed system’s interactive rehearsal environment’s capabilities.

Last winter, University of Delaware senior Rana Tuncer (left), a computer science major, piloted the virtual reality training program for Neslihan Yilmaz Sezer (right), associate professor in the Department of Midwifery, Ankara University in Ankara, Turkey.


Meanwhile, for Tuncer, Lucero-Palacios and the other students involved in the Human-Computer Interaction Laboratory, developing the VR training tool offered the opportunity to enhance their computer science, data science and artificial intelligence skills outside the classroom.


“There were lots of interesting hurdles to overcome, like figuring out a lip-sync tool to match the words to the avatar’s mouth movements and figuring out server connections and how to get the languages to switch and translate properly,” Tuncer said.


Lucero-Palacios was fascinated with developing text-to-speech capabilities and the ability to use technology to impact patient care.


“If a nurse is well-equipped to answer difficult questions, then that helps the patient,” said Lucero-Palacios.


The project is an ongoing research effort in the Barmaki lab that has involved many students. Significant developments occurred during the summer of 2024 when undergraduate researchers Tuncer and Lucero-Palacios contributed to the project through funding support from the National Science Foundation (NSF). However, work began before and continued well beyond that summer, involving many students over time. UD senior Gavin Caulfield provided foundational support to developing the program’s virtual environment and contributed to development of the text-to-speech/speech-to-text capabilities. CIS doctoral students Fahim Abrar and Behdokht Kiafar, along with Pinar Kullu, a postdoctoral fellow in the lab, used multimodal data collection and analytics to quantify the participant experience.


“Interestingly, we found that participants showed more positive emotions in response to patient vulnerabilities and concerns,” said Kiafar.



The work builds on previous research Barmaki, an assistant professor of computer and information sciences and resident faculty member in the Data Science Institute, completed with colleagues at New Jersey Institute of Technology and University of Central Florida in an NSF-funded project focused on empathy training for healthcare professionals using a virtual elderly patient. In the project, Barmaki employed machine learning tools to analyze a nursing trainee’s body language, gaze, verbal and nonverbal interactions to capture micro-expressions (facial expressions), and the presence or absence of empathy.


“There is a huge gap in communication when it comes to caregivers working in geriatric care and maternal fetal medicine,” said Barmaki. “Both disciplines have high turnover and challenges with lack of caregiver attention to delicate situations.”

When these human-human interactions go wrong, for whatever reason, it can extend beyond a single patient visit. For instance, a pregnant woman who has a negative health care experience might decide not to continue routine pregnancy care.


Beyond the project’s potential to improve health care professional field readiness, Barmaki was keen to note the benefits of real-world workforce development for her students.


“Perceptions still exist that computer scientists work in isolation with their computers and rarely interact, but this is not true,” Barmaki said, pointing to the multi-faceted team members involved in this project. “Teamwork is very important. We have a nice culture in our lab where people feel comfortable asking their peers or more established students for help.”


Barmaki also pointed to the potential application of these types of training environments, enabled by virtual reality, artificial intelligence and natural language processing, beyond health care. With the framework in place, she said, the idea could be adapted for other types of training involving human-human interaction, say in education, cybersecurity, even in emerging technology such as artificial intelligence (AI). Keeping people at the center of any design or application of this work is critical, particularly as uses for AI continue to expand.


“As data scientists, we see things as spreadsheets and numbers in our work, but it’s important to remember that the data is coming from humans,” Barmaki said.


While this project leverages computer vision and AI as a teaching tool for nursing assistants, Barmaki explained this type of system can also be used to train AI and to enable more responsible technologies down the road. She gave the example of using AI to study empathic interactions between humans and to recognize empathy.


“This is the most important area where I’m trying to close the loop, in terms of responsible AI or more empathy-enabled AI,” Barmaki said. “There is a whole area of research exploring ways to make AI more natural, but we can’t work in a vacuum; we must consider the human interactions to design a good AI system.”


Asked whether she has concerns about the future of artificial intelligence, Barmaki was positive.


“I believe AI holds great promise for the future, and, right now, its benefits outweigh the risks,” she said.

Expert Q&A: What is Soft Diplomacy and how does it impact classrooms

"Right now, storytelling is critical. Language learning is highly personal, and it’s the person-to-person relationships that grease the wheels," says Cheryl Ernst, director of the English Language Institute at the University of Delaware. She recently published English Language Programs as Facilitators of Soft Diplomacy in Innovations in Star Scholars Press. Here's how she's discussing this important topic.  Q: What is the focus of this research, and why is it important? Ernst: ELI and other English language programs provide the ideal space for communication development, cross cultural appreciation, gaining life skills, and raising awareness about people beyond the media. Post pandemic, we’re hearing across campus how individuals feel less connected, and in English language classrooms, connection is critical. Language is only learned through production and practice since it’s a skill that needs to be honed. In language, there is no such thing as perfect. In our classrooms, English is the common goal, and everyone comes to that space at their own levels and overflowing with imperfection. Our students learn to use their vulnerability as a tool. They learn the value of a growth mindset living in a culture that is different from their own, and with that comes an appreciation for difference, respect for others, trust, human-to-human communication. Q: What inspired this research? Ernst: More than 30 years of observation, conversations, experiences, and personal relationships. There was no term for what English language programs do beyond grammar (what’s perceived, anyway). Terms like personal diplomacy, person-to-person diplomacy, civic diplomacy, and the like happens all the time and oversimplifies what we do. In my readings, I started to see overlaps between soft power and diplomacy, which led to the concept of Soft Diplomacy. Then what distinguishes Soft Diplomacy from other more common monikers are the variety of skills that happen organically in our classrooms that we rarely acknowledge and students may not recognize. Q: What are some key findings or developments? Ernst: Institutionally: ELPs can do better highlighting the skills beyond English that we teach organically or deliberately. Q: How could this work potentially impact the field or the wider public? Ernst: Respecting ELPs for the space they provide and the skills they offer. It’s not “just English,” rather is learning to communicate in a common language and with people from around the globe. I’d like people to realize that relationships are foundational, that there are common values across nations and that differences are not bad. What version of English is “correct” British or American (the New York? Wisconsin? Alabama? Iowa?). Q: What are the next steps or upcoming milestones in your research? Ernst: A former student and I have launched a podcast series called Soft Diplomacy in Action that focuses on personal stories from those who work in international education. We’ve interviewed an ELI associate professor from Morocco, the UD coordinator of the Mandela Fellows program, a professor who sees (and lives) the diplomatic value of sports, and a retired English language professional. We’re looking forward to continuing these conversations with individuals from a variety of disciplines that also work in this space but through different lenses. ABOUT CHERYL ERNST Cheryl Ernst is the director of the English Language Institute at the University of Delaware where she and her colleagues and students practice Soft Diplomacy every day. Her professional areas of interest include program administration and international marketing, teacher training and working with international teaching assistants, curriculum design, and advanced level academic English (graduate levels).

AI gives rise to the cut and paste employee

Although AI tools can improve productivity, recent studies show that they too often intensify workloads instead of reducing them, in many cases even leading to cognitive overload and burnout. The University of Delaware's Saleem Mistry says this is creating employees who work harder, not smarter. Mistry, an associate professor of management in UD's Lerner College of Business & Economics, says his research confirms findings found in this Feb. 9, 2026 article in the Harvard Business Review. Driven by the misconception that AI is an accurate search engine rather than a predictive text tool, these "cut and paste" employees are using the applications to pump out deliverables in seconds just to keep up with increasing workloads. Mistry notes that this prioritization of speed over accuracy is happening at every level of the organization: • Junior staff: Blast out polished looking but unverified drafts. • Managers: Outsource their ability to deeply learn and critically think in order to summarize data, letting their analytical skills atrophy. • Power users: Build hidden, unapproved systems that bypass company oversight. A management problem, not a tech problem "When discussing this issue, I often hear leaders blame the technology. However, I believe that blaming the tech is missing the point; I see it as a failure of leadership," Mistry said. "When already overburdened employees who are constantly having to do more with less are handed vague mandates to just use AI without any training, they use it to look busy and produce volume-based work. Because many companies still reward the volume of work produced rather than the actual impact, employees naturally use these tools to generate slick but empty deliverables." "I believe that blaming the tech is missing the point; I see it as a failure of leadership. Because many companies still reward the volume of work produced rather than the actual impact, employees naturally use these tools to generate slick but empty deliverables." The real costs to organizations and incoming employees Mistry outlines three risks organizations face if they don’t intervene: 1. The workslop epidemic "These programs allow people to generate massive amounts of workslop, which is low-effort fluff that looks good but lacks substance. It takes seconds to create, but hours for someone else to decipher, fact-check, and fix," Mistry notes. "This drains money (up to $9 million annually for large companies) and destroys morale. As an educator, researcher, and a person brought into organizations to help fix problems, I for one do not want to be on the receiving end of a thoughtless, automated data dump, especially on tasks that require real skill and deep thinking." 2. Legal disaster He also states, "When the cut and paste mentality makes its way into professional submissions, the risks to the organization are real and oftentimes catastrophic. Courts have made it perfectly clear: ignorance is no excuse. If your name is on the document, you own the liability. Recently, attorneys have faced severe sanctions, hefty fines, and case dismissals for blindly submitting fake legal citations made up by computers." 3. A warning for incoming talent For new graduates entering this environment, Mistry offers a warning: Do not rely on AI to do your deep thinking. "If you simply use AI to blast out polished but unverified drafts, you become a replaceable 'cut and paste' employee," he says. “To truly stand out, new grads must prove they have the discernment to review, tweak, and challenge what the computer writes. The hiring edge is no longer just saying, 'I can do this task,' but 'I know how to leverage and correct AI to help me perform it.'" Four ideas to fix it To survive and indeed thrive with these new tools and avoid the unintended consequences of untrained staff, organizations should: 1. Reinforce the importance of fact-checking and editing: Adopt frameworks that teach employees how to show their work and log how they verified computer-generated facts. 2. Change the incentives: Stop rewarding busy work, useless reports, and massive slide decks. Evaluate employees on accuracy and results. 3. Eradicate superficial work: Don’t use automation to speed up ineffective legacy processes. Instead, use it to identify and eliminate them entirely. 4. Make time for editing: Give yourself and your employees the breathing room to actually review, tweak, and challenge what the computer writes instead of accepting the first draft. Mistry is available to discuss: Why AI is causing an epidemic of corporate "workslop" (and how to spot it). The leadership failure behind the "cut and paste" employee. How to rewrite corporate incentives to measure impact instead of volume in the AI era. Strategies for implementing safe, effective AI policies at work. How new college graduates can avoid the "workslop" trap in their first jobs. To reach Mistry directly and arrange an interview, visit his profile and click on the "contact" button.

The science behind the blood moon: Understanding this lunar phenomenon ahead of march's event

March's celestial event – a blood moon – is just around the corner. This captivating lunar spectacle isn't just a cool sight to behold; it has some neat science backing it up. The blood moon phenomenon happens during a total lunar eclipse. "During a total lunar eclipse, the only light that reaches the surface of the moon is refracted through the Earth's atmosphere, which essentially acts like a lens. Light is a wave, and every color of the rainbow has a different wavelength – red the longest and violet the shortest," said Bennett Maruca, associate professor of physics and astronomy at the University of Delaware.  What adds to the excitement is the rare nature of total lunar eclipses. While partial eclipses occur more frequently, a full blood moon isn't an everyday event. Depending on where you live, the blood moon may only grace the night skies a few times a decade. "One of my favorite things about total lunar eclipses is that it's hard to know ahead of time quite what it will look like. The moon can take on a color ranging from burnt orange to red to grayish brown," he said. "The closer the Moon passes to the center of Earth's shadow, the darker the color will be."  Maruca is available to speak about the event, which takes place in the wee hours of March 3. He can discuss when to wake up to see the phenomenon and how to best capture it.  "For photographing the moon, I would recommend a camera with some optical zoom – the moon is only about 0.5 degrees across. Because of the low lighting conditions, a tripod or other support would be helpful since a longer exposure time will be needed," he noted.  He has appeared in a number of outlets including Mashable and The Philadelphia Inquirer. He can be contacted by clicking on his profile.  ABOUT BENNET MARUCA Bennett Maruca serves as an associate professor in the University of Delaware's department of physics and astronomy. His research focuses on the sun, the solar wind and other space plasmas. He is a recipient of the Antarctic Service Medal and NASA's Silver Achievement Medal. He also serves as an associate director of the Delaware Space Grant Consortium and is currently mentoring over twenty undergraduate students developing experiments to fly into space to observe Earth's ionosphere.
