A Virtual Reality System For Practicing Conversation Skills For Children With Autism, Natalia Stewart Rosenfield, Kathleen Lamkin, Jennifer Re, Kendra Day, Louanne E. Boyd, Erik J. Linstead

Engineering Faculty Articles and Research

We describe a virtual reality environment, Bob’s Fish Shop, which provides a system where users diagnosed with Autism Spectrum Disorder (ASD) can practice social interactions in a safe and controlled environment. A case study is presented which suggests such an environment can provide the opportunity for users to build the skills necessary to carry out a conversation without the fear of negative social consequences present in the physical world. Through the repetition and analysis of these virtual interactions, users can improve social and conversational understanding.

3d Procedural Maze & Cave Generation, Jacob Sharp

Student Scholar Showcase

The goal of this project is to generate a maze or cave procedurally so that a player may be able to explore infinitely without a reoccurring pattern. The project also utilizes Virtual Reality (VR); the user will be able to put on a VR Headset and become more immersed in a procedural environment. One of the challenges that needed to be overcome was simple random number generators did not generate natural looking worlds. Introducing VR to the project created the additional challenge of preventing the user from becoming motion sick. These challenges were both addressed through many hours of research …

Gradel, Brennon Gee, Malachi Marshall, Nathan Barlow, James Osborne

The Research and Scholarship Symposium (2013-2019)

Grading homework is a major time-consuming process for professors. This is especially true of computer science professors who each teach multiple sections and classes. Our Senior design project, Gradel is a web application created to help professors with this task. It does this in two ways, firstly by allowing the professors to create customized assignments, problems, test cases and correct solutions. After a class is created our application compares the student's submission with the professor’s solution to automatically grade the submissions. This is also very helpful for students, by giving them instant feedback it allows them to make corrections or …

Exploring The Relationships Of Email Overload, Stress And Burnout In Social Workers, Lisa M. Lowrie

Social Work Doctoral Dissertations

Technostress is the inability to cope with information and communication technology which may result in stress and burnout. Email overload, stress, and burnout among social workers is a phenomenon that may impact retention in social and human service organizations. This mixed methods design uses the transactional theory of stress as the theoretical framework for measuring the relationship of email overload (email invasion, email volume, and email rapid response extraction) to stress and burnout in the social work workforce. This dissertation also explores the generational cohort, gender, and social work degree as predictors of email overload. Participants in this study were …

The Effect Of Usability Research On The World Class Sports Website, Lydia Winters, Carter Bowman, Kaitlyn Campbell, Jason Reid

User Interface Design (UI) and User Experience Design (UX) have become important parts of integrating the human experience into the design of digital products and services we use every day. Usability Research is the foundation of these two areas. It enables the research for improvement of quality interaction between a user and a company (UX) to be put into action by designing, prototyping and iterating the user interface (UI) before development. This project is a study of the effect that usability research has on the development of a new website for World Class Sports. It implements changes to the site …

Design For Safety: Decreasing First Responder Health Risks Through Real-Time Bio-Sensor Alerts, Suzy Fendrick

UNO Student Research and Creative Activity Fair

The focus of this research project is using the Design Thinking process to create an informative dashboard for first responders. Design Thinking involves empathizing with the user, defining the problems to be solved, ideation, creating prototypes, and testing. This iterate process focuses on the user, resulting in the most effective product possible. The dashboard will display real-time biosensor data from sensors in the first responders’ uniforms. This project is part of a larger project with the goal of vastly improving the safety of first responders during emergency hazardous material incidents.

Forensics Analysis For Bone Pair Matching Using Bipartite Graphs In Commingled Remains, Ryan Ernst

UNO Student Research and Creative Activity Fair

Identification of missing prisoners of war is a complex and time consuming task. There are many missing soldiers whose remains have yet to be returned to their families and loved ones. This nation has a solemn obligation to its soldiers and their families who have made the ultimate sacrifice for their country. There are currently over 82,000 unidentified prisoners of war which are identified at a rate of 100+ per year. At this rate it would take 300+ years to complete the identification process. Previously, anthropologists used excel spreadsheets to sort through skeletal data. This project aims to streamline the …

Collecting Virtual And Augmented Reality In The Twenty-First Century Library, Matthew Hannah, Sarah Huber, Sorin Adam Matei

Matei Interdisciplinary Research Collaboratory

In this paper, we discuss possible pedagogical applications for virtual and augmented reality (VR and AR), within a humanities/social sciences curriculum, articulating a critical need for academic libraries to collect and curate 3D objects. We contend that building infrastructure is critical to keep pace with innovative pedagogies and scholarship. We offer theoretical avenues for libraries to build a repository 3D object files to be used in VR and AR tools and sketch some anticipated challenges. To build an infrastructure to support VR/AR collections, we have collaborated with College of Liberal Arts to pilot a program in which Libraries and CLA …

Developing A Contemporary And Innovative Operating Systems Course, Saverio Perugini, David J. Wright

Computer Science Faculty Publications

This birds-of-a-feather provides a discussion forum to foster innovation in teaching operating systems (os) at the undergraduate level. This birds-of-a-feather seeks to generate discussion and ideas around pedagogy for os and, in particular, how we might develop a contemporary and innovative model, in both content and delivery, for an os course—that plays a central role in a cs curriculum—and addresses significant issues of misalignment between existing os courses and employee professional skills and knowledge requirements. We would like to exchange ideas regarding a re-conceptualized course model of os curriculum and related pedagogy, especially in the areas of mobile OSs and …

Making Wearable Sensing Less Obtrusive, Huy Vu Tran, Archan Misra

Research Collection School Of Computing and Information Systems

Sensing is a crucial part of any cyber-physical system. Wearable device has its huge potential for sensing applications because it is worn on the user body. However, wearable sensing can cause obtrusiveness to the user. Obtrusiveness can be seen as a perception of a lack of usefulness [1] such as a lag in user interaction channel. In addition, being worn by a user, it is not connected to a power supply, and thus needs to be removed to be charged regularly. This can cause a nuisance to elderly or disabled people. However, there are also opportunities for wearable devices to …

Single Image Super-Resolution, Yujing Song

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Super-Resolution (SR) of a single image is a classic problem in computer vision. The goal of image super-resolution is to produce a high-resolution image from a low-resolution image. This paper presents a popular model, super-resolution convolutional neural network (SRCNN), to solve this problem. This paper also examines an improvement to SRCNN using a methodology known as generative adversarial net- work (GAN) which is better at adding texture details to the high resolution output.

Real-Time Ray Traced Global Illumination Using Fast Sphere Intersection Approximation For Dynamic Objects, Reed Phillip Garmsen

Master's Theses

Realistic lighting models are an important component of modern computer generated, interactive 3D applications. One of the more difficult to emulate aspects of real-world lighting is the concept of indirect lighting, often referred to as global illumination in computer graphics. Balancing speed and accuracy requires carefully considered trade-offs to achieve plausible results and acceptable framerates.

We present a novel technique of supporting global illumination within the constraints of the new DirectX Raytracing (DXR) API used with DirectX 12. By pre-computing spherical textures to approximate the diffuse color of dynamic objects, we build a smaller set of approximate geometry used for …

Explainable Reasoning Over Knowledge Graphs For Recommendation, Xiang Wang, Dingxian Wang, Canran Xu, Xiangnan He, Yixin Cao, Tat-Seng Chua

Research Collection School Of Computing and Information Systems

Incorporating knowledge graph into recommender systems has attracted increasing attention in recent years. By exploring the interlinks within a knowledge graph, the connectivity between users and items can be discovered as paths, which provide rich and complementary information to user-item interactions. Such connectivity not only reveals the semantics of entities and relations, but also helps to comprehend a user’s interest. However, existing efforts have not fully explored this connectivity to infer user preferences, especially in terms of modeling the sequential dependencies within and holistic semantics of a path. In this paper, we contribute a new model named Knowledgeaware Path Recurrent …

Improved N-Dimensional Data Visualization From Hyper-Radial Values, Todd J. Paciencia, Trevor J. Bihl, Kenneth W. Bauer

Faculty Publications

Higher-dimensional data, which is becoming common in many disciplines due to big data problems, are inherently difficult to visualize in a meaningful way. While many visualization methods exist, they are often difficult to interpret, involve multiple plots and overlaid points, or require simultaneous interpretations. This research adapts and extends hyper-radial visualization, a technique used to visualize Pareto fronts in multi-objective optimizations, to become an n-dimensional visualization tool. Hyper-radial visualization is seen to offer many advantages by presenting a low-dimensionality representation of data through easily understood calculations. First, hyper-radial visualization is extended for use with general multivariate data. Second, a method …

We Have Always Been Virtual: Gilles Deleuze And The Computer-Generated Image, Hugh Mccabe

Conference papers

The use of computer-generated imagery is becoming increasingly ubiquitous across many fields including media, advertising, architecture and art. This represents a fundamental shift within visual culture, as imagery can now be produced routinely by means of rendering algorithms based on spatial representations. We propose that the account of the image provided by Gilles Deleuze in his books on cinema provides a rich philosophical framework for understanding such contemporary imaging practices. By providing a Deleuzian reading of James Kajiya's 1986 rendering equation we argue that there is a tacit ontology of the image underwriting both Deleuze’s work on cinema and current …
