Research Permissions Management System
The Research Permissions Management System (RPMS) is a new and innovative solution developed from a grant from the National Library of Medicine at the National Institute of Health to address the challenges associated with collecting and managing informed consents and research permissions in both clinical care and research settings. The current paper-based methods are often time-consuming, difficult to manage, and prone to errors, leading to low patient trust and poor research participant recruitment. RPMS provides a comprehensive and electronic mechanism to capture and manage informed consents, research authorizations, and patient permissions in a centralized and secure manner. This system is designed to improve the efficiency, accuracy, and transparency of the informed consent and research authorization process, thereby enhancing patient trust and increasing research participant recruitment.
The RPMS software is available for download here.
Fuel Rod Inspection Simulator
The Fuel Rod Inspection Simulator (FRINSim) is a training tool designed to teach nuclear material inspectors the skills required for visually inspecting fuel rods. In the nuclear industry, fuel rods contain nuclear fuel, which needs to be inspected regularly to ensure the safety and integrity of the fuel and the reactor. The objective of FRINSim is to provide a realistic and effective training environment for nuclear material inspectors to develop and refine their inspection skills. By using FRINSim, inspectors can practice detecting and analyzing defects in simulated fuel rods without the risk associated with inspecting actual fuel rods. The results of this training are expected to enhance the skills and confidence of nuclear material inspectors, leading to more accurate and consistent inspections and ensuring the safety of nuclear reactors.
Simulators built for Experimental Studies
Studies on human adaptation to latency in teleoperated multi-robot human-agent teams
Teleoperated missions often involve communication delays, referred to as latency, which can have significant impacts on the performance, workload, trust, and usability of the system. In order to better understand these impacts, this study investigates the effects of latency on a set of dependent variables. The dependent variables include performance, measured by both the time required to complete a task and the number of errors made, subjective workload, trust, and usability. The study was conducted using a simulated search-and-rescue mission, and the effects of latency were evaluated across two levels of two independent variables. The results of this study will provide valuable insights into the relationship between latency and various aspects of teleoperated mission performance and usability, and can inform the design and optimization of teleoperated systems for various applications, such as search-and-rescue, space exploration, and military operations.
Interfaces to support the situation awareness of Remotely Operated Vehicle (ROV) Operators
This project aims to advance the state of the art in remote underwater vehicle (ROV) operations by developing and evaluating interfaces that enhance situation awareness among ROV operators who are working as a team. Situation awareness refers to the understanding of the current state of an environment, and is critical for effective and safe ROV operations, especially when multiple operators are involved. By building and testing these interfaces, the goal of this project is to provide ROV operators with the information they need to make informed decisions, respond to unexpected events, and coordinate their actions with their team members. The results of this project will provide insights into the design of effective and usable interfaces for supporting situation awareness in ROV operations, and will inform the development of advanced technologies that can improve the performance and safety of ROV operations.

To further explore the benefits of these new technologies, virtual reality environments have been specifically designed to support collaborative work. Controlled experimental studies have been conducted to compare the effectiveness of using immersive virtual reality-based settings for collaborative work as compared to traditional methods. These studies aim to provide insights into how the use of virtual reality environments can impact collaboration processes, such as communication, decision making, and task performance. The results of these studies have the potential to inform the development and implementation of virtual reality-based solutions for collaborative work, leading to increased productivity, efficiency, and satisfaction among teams.
Virtual Reality Environments for Empathy Generation among Informal Caregivers of Dementia Patients
Several studies have highlighted the importance of educating informal caregivers and the general public about the symptoms and behavioral changes associated with dementia. It is believed that acquiring this knowledge can increase feelings of competence and decrease psychological distress among these caregivers. To address this need, a collaborative virtual reality-based simulation has been developed in which informal caregivers take on the perspective of a person with dementia. This simulation mimics the visual impairments that often accompany conditions such as macular degeneration, cataracts, and glaucoma, thus providing caregivers with a more immersive and realistic understanding of what it is like to live with these conditions. Additionally, participants are provided with plastic ribbed shoe inserts that mimic the sensory handicaps that can occur with aging and dementia, further enhancing the overall simulation experience. By providing informal caregivers with a more immersive understanding of the experience of living with dementia, this virtual reality-based simulation has the potential to significantly impact their knowledge, competence, and well-being.
Visualization strategies to support the situational awareness of windstorm risk engineers
This simulation was designed to examine the impact of different context-based visualization strategies on the situational awareness and performance of windstorm risk engineers. The independent variable in the study is the type of context-based visualization used, which was manipulated at three levels: the absence of any visual aids, the use of a checklist-based visual aid, and the use of a predictive display-based visual aid. The purpose of the study is to explore how various context-based visualization strategies can support the situational awareness needs of windstorm risk engineers and impact their overall performance. The results of this study will provide valuable insights into the most effective methods for enhancing situational awareness in high-stakes and complex work environments, and can inform the design and implementation of visualization tools in such settings.
