Research Statement

My research areas are Human-Computer Interaction (HCI) and Computer Supported Cooperative Work (CSCW). As technology continues to be increasingly utilized in every aspect of our daily lives, there are ever more opportunities for computer scientists. As computer scientists, we improve these technologies and in turn our daily lives in many ways. As “HCIentists” (often also computer scientists), we focus our attention on improving how well the technologies suit us in “being the selves we wish we were” [4]. In HCI we consider not only how quickly a task can be accomplished with technology, but also (e.g.) whether the task should be completed with technology, and whether it should be completed quickly. Beginning back in my undergraduate software development in support of the UNC Housing department, continuing through my undergraduate research and industrial (IBM) experience in Assistive Technologies, my industrial experience with custom, multi-platform, and mobile business solutions (Red Hat), through my graduate studies at Virginia Tech including my industrial research internship (Xerox), I have seen that it is often more than whether a technology or software fulfills the requirements, but myriad other nuanced considerations of how people will use, appropriate, and adapt technologies that determines whether they are successful. My interest in how and why people behave and use technologies in the ways they do influences my design, implementation, and deployment of meaningful technologies that make the world a bit better by helping people be the people they wish they were.

In my master’s thesis work for example, I investigated the effects of transparency on group work. In a world where technologically supported group work seems to automatically mean immediate sharing of everything each group member does (total transparency), I looked at how this transparency might affect individuals working in groups. I found promising preliminary evidence that increased transparency may result in more contributions to group work, but that people in the less-transparent condition thought (1) others built on their ideas, (2) their imaginations were captured by others’ ideas, and (3) they built on others ideas more than participants in the more-transparency condition [1]. In an era of Google Docs and its competitors implementing real-time collaboration in as completely transparent a way as possible, it is important to consider the assumption that transparency is the most important design goal for group collaborations.

In pursuit of other ways to design to help us be the selves we wish we were, my dissertation work (Colisten) looks what it means to “feel together” with a friend or family member (a human need) and explores the potential for technology to facilitate people in meeting this need. For many, something as simple as listening to music at the same time as a remote friend or family member is sufficient to elicit the feeling of warm companionship that we may feel when co-located [3].

Aside from looking at how technology can support us in maintaining relationships we care about, another arena I am interested in utilizing technology to design better, more meaningful interactions, is in education in the classroom and out. For example, in ThoughtSwap, we are interested in how students discuss their course content. In particular, we are interested in facilitating students in expressing and in considering counter-attitudinal points of view [2]. Adults who can express, consider, discuss, and critique others points of view are well suited to make important decisions as citizens of a democratic political system, as laborers for companies, parents of children, and etc.

Along with many others in computing, especially in computer science education, I have investigated computational thinking. Being interested in increasing the diversity not only of people who go into careers in computing, but also the diversity of adults in every field who have certain competencies with respect to computing, I have explored the potential of proto-computational thinking to increase participant in computing. More specifically, I have worked with teachers in middle schools to explore integrating computational thinking into core curriculum [5] through research, development, and testing of technological interventions in core curricular areas.

To investigate questions and address problems that are meaningful today, interdisciplinarity is key. From the research methods themselves and the members of the research team, to the domains of study and the ways and means of communicating the findings, working together with a diverse team is critical to success. I have found my experiences working with diverse and interdisciplinary teams in academia and industry to be exciting and rewarding. In particular, working with undergraduate students as they learn what research is, and how to put the development skills they learn in class to use in software people can use has been my favorite part of my post-graduate studies. While interdisciplinary teams often entail significant work in communication and coordination, the opportunity to learn from my collaborators and to think about problems not often considered within my own discipline opens the door to new research directions.

I look forward to continuing my work researching how to help people be the selves they wish they were in diverse, interdisciplinary teams.

Colisten
Colisten-60@x3My dissertation work explores people’s feelings of “togetherness” through offering them a novel kind of mediated experience.  Many technologies today are “social”, but many of them can leave us feeling lonely.  Colisten enabled people to listen to the same music at the same time as their “framily”, close friends and family, even when they are far away.  Experiencing music at the same time as another person can provide some of the feelings and experiences of having spent time with them.

Master’s Thesis

Design Game
Screenshot 2016-10-01 14.05.38In my Master’s Thesis, I studied the effects of privacy, in the form of transparency, on group interaction in a CSCW scenario. For this work I reviewed prior work, designed the study, recruited project staff, trained the project staff to assist in data collection, collected data (system logs, researcher observations, video), analyzed the data (including video transcription and coding), and wrote the thesis.

AlgoViz
algovizI worked on AlgoViz with Prof. Shaffer, AJ Alon, and Monika Akbar. AlgoViz aims to provide a portal where educators can share algorithm visualizations that are useful in teaching. In addition to sharing the visualizations themselves, the portal supports the instructors in sharing their experiences using various visualizations in instructors’ varied contexts. My role was assisting in migrating much of the content form a wiki to Drupal. Additionally, I began the work of user experience and design overhaul.

ChairMouse
Screenshot 2016-10-01 14.09.35I worked with Prof. North, Christopher Andrews, Haeyong Chung, and Alex Endert on Alex’s ChairMouse idea. When using large, high-resolution displays with computers, a user will often still use a conventional mouse as their pointing device. The problem is that with so many more pixels to traverse, the user must often resort to “clutching” or “rowing” where they move the mouse to one extreme of the mousepad, lift the mouse, and replace it at the opposite extreme to continue moving the cursor in the same direction. Our relatively low-cost and low-tech prototype worked surprisingly well.
I helped with literature review, building a sensor to detect mouse “rowing” or “clutching”, study design and execution (data collection), data analysis, and write-up.

Clock Partners
Screenshot 2016-10-01 14.08.18In some contexts (such as elementary classrooms) teachers may want to orchestrate classroom activities in part by composition of class small group or pair composition (e.g. Collaborate with Clock Partners). In collaboration with elementary school teachers, and a Mathematician (Jim Dickson), I wrote a small web application to facilitate this process. This application relies on modern web technology (javascript and svg) to be able to quickly produce the clock faces that a teacher can then print and distribute to their students.

Astronomical Proportions
Screenshot 2016-10-07 09.11.29With support from the NSF, we worked with middle school teachers to understand the parts of their curriculum that they were least pleased with, and to target those areas as potential for integrating (proto-)computational thinking. I met regularly with a middle school science teacher, observed their class, and developed a robust prototype. Then, I went to the class again to observe the teacher using the prototype in their lessons. I collected data (observations of the class, discussions with the teacher, and logs form our system), developed the prototype, and wrote up the results.
