Incoming Ph.D. Student - University of Maryland, College Park
Hi! I am an incoming Ph.D. student in the Embodied Dynamics Laboratory (EmD) at the University of Maryland, College Park, advised by Dr. Jun Nishida. My research area is at the intersection of human-computer interaction (HCI), extended reality (XR), learning science, and psychophysics. Historically, my research has been in XR and education; studying virtual reality (VR) locomotion and how immersion in XR environments affects the learning process with Dr. Dinesh Manocha at the UMD GAMMA Lab. Recently, I have been interested in factoring in HCI more broadly, as well as other psychophysical and cognitive effects during learning. In my free time, I enjoy rollerblading, reading about history and math, and retro video games!

In Bad Faith: Assessing Good and Bad Faith Conversations on Social Media. J Golbeckâ , L Stevensâ , C Shermanâ , R Gnanasekaranâ , A Leitchâ , B Zarrellaâ , C Sternâ , E Cotugnoâ , W Conwayâ , E Kleinâ , K Hamiltonâ , C Chenâ ACM Conference on Human Factors in Computing Systems (CHI), 2025 [Submitted] In this paper, replies to tweets from mainstream media outlets and official government agencies were analyzed and assessed for whether they were in good faith, engaging honestly and constructively with the original post, or bad faith, attacking the author or derailing the conversation. |

Sensitivity to Redirected Walking Considering Gaze, Posture, and Luminance. NL Williams, L Stevens, A Bera, D Manocha IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR), 2025 [Submitted] We study the correlations between redirected walking (RDW) rotation gains and patterns in usersâ posture and gaze data during locomotion in virtual reality (VR). Our results showed that, in general, physiological signals were significantly positively correlated with the strength of redirection gain, the duration of trials, and the trial number. Results showed that there were no significant differences in RDW detection thresholds between the photopic and mesopic luminance conditions. These results provide, for the first time, a direct link between the strength of RDW gains and properties of usersâ gaze and posture data. |

An Overview of Enhancing Distance Learning Through Augmented and Virtual Reality Technologies. L Stevens*, E Childs*, F Mohammad*, H Burbelo, A Awoke, N Rewkowski, D Manocha IEEE Transactions on Visualization and Computer Graphics (TVCG), Volume 30, Issue 8 | Pages 4480 - 4496, 2023 IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR), 2024 [Paper] [arXiv] [IEEE TVCG Link] [DOI] Although distance learning presents a number of interesting educational advantages as compared to in-person instruction, it is not without its downsides. We first assess the educational challenges presented by distance learning as a whole and identify challenges that distance learning currently presents as compared to in-person instruction. After assessing each of these challenges in-depth, we examine how AR & VR technologies might serve to address each challenge along with their current shortcomings, and finally outline the further research that is required to fully understand the potential of AR & VR technologies as they apply to distance learning. |

Artificial Intelligence and the Arts: Towards AI-Guided Accessible Learning Spaces in Virtual Reality. L Stevens, LA Weissman, J Steigelman, M Bouabid 7th Annual Brown University CS Undergraduate Research Symposium, 2022 [Research Award] [Poster] [Demo Video] Under the supervision of Dr. James Tompkin, my colleagues and I investigated how artificial intelligence (AI) could be used to improve accessibility in learning environments. This was done during my time in the 2022 Google exploreCSR Program, an initiative to cultivate research on socially-responsible AI for computational creativity. Our project found that the cloud-based systems trained on the general image dataset produced captions of inconsistent quality in an unsatisfactory amount of time for general use. However, we provided a proof of concept and recommendations to future researchers in this area such as the utilization of a more specialized dataset, locally-ran AI models, and new XR accessibility tools. |

VR RT2: VR-Integrated Real-Time RaceTrack Simulator Angelos Mavrogiannis, Zining Zhang, Logan Stevens, Elliot Huang, Hyekang Kevin Joo In this paper, we present an interactive system that converts a physical racetrack to a VR-simulated racing environment. The user begins by constructing a physical racetrack using a set of 3D-printed track pieces on a 3D-printed baseboard that resembles a chessboard. A top-down view of the 2D design of the track is captured in real time with an overhead camera. The track pieces are segments of straight or curved lines to model a straight part of a road or a turn, and the user can incorporate additional functionalities upon some of these pieces. Each of the pieces has an ArUco marker glued on its center, which is detected from the captured video stream. By extracting the coordinates and marker ID of each of the markers we compute their relative position and orientation to create an occupancy grid representation of the physical map in a matrix form which is saved to a shared file at every frame. The shared file is then processed and decoded in a real-time Unity environment which renders the virtual racetrack. |

Augmented Reality Building Analytics and Maintenance Project William Ingold, Marko Neskovic, Logan Stevens The University of Maryland, College Park's Iribe Center building has been imbued with countless sensors and systems that are accessible to its maintenance workers. While workers can access information about the status of these sensors and system, quick mobile access on-the-go is not currently achievable except through standard interfaces. However, mapping from a 2D surface, such as a desktop, to a classroomâs environment can be difficult to visualize. As such, we propose an augmented reality application which provides a maintenance overlay of the building. This allows workers to simply look at building systems in person and discover their statuses that overlay their physical counterparts. |
Ever since I was an instructional design intern at UMD's Office of Transformational Learning, I have been captivated by the task of applying a formalized structure to the learning process. I employ the skills I have learned during that internship in my teaching, scholarship, research, and daily life. My abilities in public speaking and acting help greatly in engaging students.
