In this project, we aim to develop and evaluate displays of automation uncertainty that aid in the transition of control from automated to manual driving. Currently, we are focused on two manipulations of these displays. The first manipulation, metric, is manipulated by presenting system reliability information (Reliability) or the level of engagement necessary for the driver (Required Driver Engagement, RDE). The second manipulation, modality, is manipulated by presenting the information visually, auditorily, or with a combination of visual and auditory information (multimodal).
Since its earliest days, flaming, trolling, harassment and abuse have plagued the Internet. Our aim is to computationally model abusive online behavior to build tools that help counter it, with the goal of making the Internet a more welcoming place. In particular, we look at a novel approach to identify online verbal abuse using cross-community linguistic similarities between posts on different communities. This work will enable a transformative new class of automated and semi-automated applications that depend on computationally generated abuse predictions.
The Aware Home, an Institute for People and Technology (IPaT) Living Lab, provides an authentic home environment in which to conduct research in the areas of: health and well-being, connected home, home security and resource management, and the future of digital media and entertainment at home. Common uses of the home include: 1. innovating the next home technology, 2. performing human subject studies of our research in a controlled environment, 3. testing installation of solutions before deploying into peoples‚ actual homes, such as those individuals enrolled in HomeLab.
This project concerns the analysis and design of a wearable technology garment intended to aid with the instruction of ballet technique to adult beginners. A phenomenological framework is developed and used to assess physiological training tools. Following this, a garment is developed that incorporates visual feedback inspired by animation techniques that more directly convey the essential movements of ballet.
Exposure to diverse opinions makes us more informed and engages society in a necessary deliberation process. Inwardly focused groups risk tunnel vision and an inability to challenge their own views. Technically, online we can connect to anyone in the world but social network analyses of blogs and Twitter have shown that we stay connected in groups of like-minded others. There is untapped potential here for online environments to go further towards giving more access to diverse views. Incivility has direct consequences for relationships with others of different opinions.
The goal of this project is to expand on the work done by Pamela Pryor and Jo Edwards (curators of the BellSouth calendar project), to remember, celebrate, and preserve stories of African Americans and Black-owned institutions in Georgia. The project consists of two parts an interactive exhibit and digital application. The exhibit and interactive installation will be located at the APEX (African-American Panoramic Experience) Museum in Atlanta, Georgia.
The BellSouth Calendar project was originally curated by Pamela Pryor and Jo Edwards. The purpose of the project is to expand on this work, remembering these narratives, and celebrate these individuals from the community. The project has two components: an interactive exhibit that will be on display at the APEX Museum(African-American Panoramic Experience) and the second is a website that will allow teachers, students, and community members to learn more.
In the U.S. alone, approximately 18 million people use crutches each year. The human body was not designed to bear its weight on the forearms and wrists, but all designs of the crutch force patients to do just this. In just a few steps with the underarm crutch, forearm fatigue sets in resulting in patients resting upon the underarm padding. The upward force from the padding leads to pain, chafing, blood vessel compression, nerve compression, and possible nerve damage.
Visualizations can help amplify human cognition. In an era where networks are becoming increasingly complex, the desirability of tools to compare and contrast sets, relationships, and reach is significant. Motivated by a practical need articulated by corporate decision makers, this research presents our journey in designing and implementing bicentric diagrams, a novel graph-based set visualization technique. A bicentric diagram enables simultaneous identification of sets, set relationships, and set member reach in integrated ego networks of two focal entities.
A social media application that aims to bridge the gaps between those with asthma and caregivers, family, and friends. Users create, share, and send virtual birthday cakes which other members of the community can contribute candles too. This application is educational and is made in collaboration with the CHEST society. 
We present a method for smoothly blending between existing liquid animations. We introduce a semi-automatic method for matching two existing liquid animations, which we use to create new fluid motion that plausibly interpolates the input. Our contributions include a new space-time non-rigid iterative closest point algorithm that incorporates user guidance, a sub-sampling technique for efficient registration of meshes with millions of vertices, and a fast surface extraction algorithm that produces 3D triangle meshes from a 4D space-time surface.
Modern social media do a remarkable job of keeping friends and families connected‚ often across the globe. Yet, these same systems also overlook the communities and neighborhoods where we live our daily lives. In this paper, we present BlockParty, a platform for building hyper-local social computing applications aimed at neighborhoods. A key feature of our platform is that it runs on top of residential wireless routers via an underlying mesh network. Using BlockParty, people can socialize with their neighbors and share resources, without their data ever leaving their local community.
In the era of globalization, the ordinary viewer is exposed to cinematography from different countries and cultures, but does one understand the cultural context portrayed by the artists? In this project, I intend to use interactive television as a medium, that helps the viewer to gain a deeper understanding of a movie, by exposing him/her to its cultural layers.
How do we understand sex difference for sex-balanced pre-clinical research? It is critical to acknowledge and include the difference in clinical research because we don't all have same bodies. We seek to bring this conversation of inclusion to Reproductive Justice Advocates and Molecular Biologists through a conversational web narrative. They will see each other's ideas and vocabularies, coming to an understanding and cornerstone for future dialogue.
