Title: "A High-Quality Digital Library Supporting Computing Education: The Ensemble Approach"
Abstract: In this research, we addressed both external and internal quality aspects of DLs. For internal qualities, we focused on completeness and consistency of the collection, catalog, and repository. We developed an application pipeline to acquire user-generated computing-related resources from YouTube and SlideShare for an educational DL. We applied machine learning techniques to transfer what we learned from the ACM Digital Library dataset. We built classifiers to catalog resources according to the ACM Computing Classification System from the two new domains, that were evaluated using Amazon Mechanical Turk. For external qualities, we focused on efficiency, scalability, and reliability in DL services. We proposed cloud-based designs and applications to ensure and improve these qualities in DL services using cloud computing. The experimental results show that our proposed methods are promising for enhancing and enriching an educational digital library.

This work received support from ACM, as well as the National Science Foundation under Grant Numbers DUE-0836940, DUE-0937863, DUE-0840719, and IMLS LG-71-16-0037-16.

Title: "High-dimensional Data in Scientific Visualization: Representation, Fusion, and Difference"
Abstract: This research examines humans' predictable bias in interpreting visual-spatial, spatiotemporal information, and inference-making in scientific visualization from a visual analytic point of view. I examined different case studies from different domains such as land suitability in agriculture, spectrum sensing in software-defined radio networks, raster images in remote sensing, pattern recognition in 3D points cloud, airflow distribution in aerodynamics, galaxy catalogs in astrophysics and protein-membrane interaction in molecular dynamics. Each case required different computing power, ranging from personal computer to high-performance cluster. Based on this experience across application domains, I propose an empirical paradigm for scientific visualization that supports three key features of scientific data analysis: representations, fusion, and visual discrimination. The results of these studies contribute to our knowledge of efficient MVMD designs and provides scientific visualization developers with a framework to mitigate the trade-offs of scalable visualization design such as the data mappings, computing power, and output modality. Ayat is starting a post-doc at Texas Advanced Computing Center (TACC) in their Visualization group.

Title:"Negotiating Ambiguity in Describing Fabrics Through Technology".
Abstract: Designers and non-designers alike often describe fabric in ways that are markedly different or unclear. For example, two designers may attribute qualities such as heavy or thick to a material, but actually mean completely different things despite using the same words.We highlight user interface designs and implementations that use the ambiguity of language without eliminating it. We studied how people described distinct fabrics, from exp erts,novices, to everyday people and the crowdsourcing community on how they interpret fabrics.We applied that information to designs that communicated materiality and ambiguity in various ways, and studied how interfaces affected a user's pro cess of exploring materials and negotiating the meaning of materiality. The most important findings are user interface guidelines that apply to any interface where ambiguity of description is a key resource, such as design."

Congratulations to Yinlin Chen on successful PhD defense

2017-09-26

Congratulations to Yinlin Chen on the successful defense of Ph.D. dissertation entitled "A High-quality Digital Library Supporting Computing Education: The Ensemble Approach". Abstract: Educational Digital Libraries (DLs) are complex information systems, which are designed to support individuals’ information needs and information seeking behavior. To have a broad impact on the communities in education and to serve for a long period, DLs need to structure and organize the resources in a way that facilitates the dissemination and the reuse of resources. Such a digital library should meet defined quality dimensions in the 5S (Societies, Scenarios, Spaces, Structures, Streams) framework including completeness, consistency, efficiency, extensibility, and reliability to ensure that a good quality DL is built. In this research, we addressed both external and internal quality aspects of DLs. For internal qualities, we focused on completeness and consistency of the collection, catalog, and repository. We developed an application pipeline to acquire user-generated computing-related resources from YouTube and SlideShare for an educational DL. We applied machine learning techniques to transfer what we learned from the ACM Digital Library dataset. We built classifiers to catalog resources according to the ACM Computing Classification System from the two new domains, that were evaluated using Amazon Mechanical Turk. For external qualities, we focused on efficiency, scalability, and reliability in DL services. We proposed cloud-based designs and applications to ensure and improve these qualities in DL services using cloud computing.

Best paper award for CHCI members at ICAT-EGVE conference

2015-11-20

Graduate student Mahdi Nabiyouni and advisor Dr. Doug Bowman received the best paper award at the prestigious ICAT-EGVE conference, for their paper "An Evaluation of the Effects of Hyper-Natural Components of Interaction Fidelity on Locomotion Performance in Virtual Reality." Paper abstract: Hyper-natural interaction techniques are intentionally designed to enhance users’ abilities beyond what is possible in the real world. We compared such hyper-natural techniques to their natural counterparts on a wide range of locomotion tasks for a variety of measures. The results show that the effects of the hyper-natural transfer function was mostly positive, however, hyper-natural techniques designed to provide biomechanical assistance had lower performance and user acceptance than those based on natural walking movements.

Title: A Mixed Methods Approach to Understanding the Attitudes of Minority Middle School Girls Toward Computer Science
Advisor: Manuel A. Perez-Quinones

Abstract: The number of women in computing is significantly low compared to the number of men in the discipline, with minority women making up an even small segment of this population. Related literature accredits phenomenon to multiple sources (e.g. background, stereotypes, discrimination, self-confidence, etc.), which includes a lack of self-efficacy or belief in ones capabilities. However, a majority of the literature fails to represent minority females, such as African Americans, in their research.

This research uses a mixed methods approach to understanding the attitudes of minority middle school girls toward computer science and the factors that influence these attitudes. Since women who do pursue computing degrees and continue with graduate education often publish in Human-Computer Interaction (HCI) in greater proportions than men, this research used an intervention to introduce minority middle school girls to computational thinking concepts through HCI. To expand the scope of the data collection, a separate group of girls were introduced to computational thinking concepts through algorithms. Data was collected through both quantitative and qualitative sources, and analyzed using inferential statistics and content analysis.

The results show that minority middle school girls generally have negative attitudes toward computer science. However, after participating in a computer science intervention, perceptions toward computer science become positive. The results also reveal that several factors influence the attitudes of middle school girls toward computer science such as the participation in an intervention, the intervention content domain, the facilitation of performance accomplishments, and participant characteristics like socioeconomic status, mother's education, school grades, the use of mobile phones and video game consoles at home.

Ji-Sun Kim named 2nd place winner in ACM Grace Hopper Celebration

2013-10-21

Congratulations to Ji-Sun Kim, 2012-2013 PHD graduate of our department with co-advisors Denis Gracanin and Francis Quek, on being named 2nd place winner of the ACM Grace Hopper Celebration Graduate Student Research Competition earlier this month. Her competition entry, entitled "Action-Transferred Design Approach of Navigation Techniques for Effective Spatial Learning in 3D Virtual Environments", describes the core part of her doctoral research.

Ji-Sun describes her research thusly: "The proposed action-transferred design approach was inspired by observations from theories of learning, action, perception, and neuropsychology. We empirically demonstrated the proposed action-transferred design approach addresses the practical usability issues of previous walking-like navigation techniques, while effectively supporting spatial learning. We believe that the action-transferred design approach can open many research opportunities and applications in human computer interaction (HCI) research area. These applications include virtual exploration of scientific datasets, historic places, or real estate, architectural or urban design, military or firefighting training, and even robotics (operation of unmanned vehicles)."

This is the 2nd year in a row that CS@VT has had a graduate student win 2nd place in this competition. As a winner of a Student Research Competition at GHC, Ji-Sun will be eligible to participate in the Grand Finals of all the ACM Student Research Competitions for 2013-2014:

Yelp Dataset Challenge: VT CHCI team wins grand prize

2013-10-09

VT CHCI graduate student Ji Wang, alumnus Sheng Guo and professor Chris North along with graduate student Jian Zhao from the University of Toronto, have won the grand prize of the Yelp Dataset Challenge. The award announcement can be found here.

The abstract of their winning project titled "Clustered Layout Word Cloud for User Generated Review" is the following: User generated reviews, like those found on Yelp and Amazon, have become important reference material for decision making in our daily life, for example, in dining, shopping and entertainment. However, the large amounts of available reviews make the reading process tedious. In this project, we present a word cloud visualization of user generated reviews based on semantics to facilitate the decision making tasks. We used a natural language processing approach, called grammatical dependency parsing, to create a semantic graph based on the review content. A force-directed layout was then applied to the semantic graph to generate the clustered layout word cloud. Our approach can afford users more insights about reviews by creating word clusters spatially based on their semantic information. We also conducted an experiment to compare the efficiency of our method with two alternative review reading techniques: random layout word cloud and normal text-based reviews. The results showed that the proposed technique had faster task completion times and better user satisfactions.

CHCI students finalists in NUMA competition

2013-09-18

Siroberto Scerbo and Felipe Bacim, Ph.D. students in CHCI and Computer Science, along with advisor Doug Bowman, have been named finalists in the 2013 Nokia Ubimedia Mindtrek Awards (NUMA). Their project "Insane Llamas" is a next-generation augmented reality game that allows players to defeat evil llamas hiding in the physical real-world environment by shooting virtual kiwis with a physical slingshot attached to an iPad. The game began as a class project in Bowman's 3D Interaction seminar. Based on a submission video, the team was named one of four winners of the competition, and will compete for the top prize Oct. 2 in Finland.
