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.
Most high-speed non-invasive BCI typing systems require intense visual attention and feedback. BrainBraille investigates a more open-loop approach similar to touch typing. BrainBraille enables communication at 20 characters per minute (cpm) by monitoring attempted movements in the motor cortex. using functional Magnetic Resonance Imaging (fMRI). Users attempt to tense the muscles for six body parts: the hands, the feet, the tongue, and the gluteus maximus. Those actions activate the corresponding six regions of the motor cortex, which map to the six dots in a Braille cell.
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.
Static visualizations have analytic and expressive value. However, many interactive tasks cannot be completed using static visualizations. As datasets grow in size and complexity, static visualizations start losing their analytic and expressive power for interactive data exploration. Despite this limitation of static visualizations, there are still many cases where visualizations are limited to being static (e.g., visualizations on presentation slides or posters). We believe in many of these cases, static visualizations will benefit from allowing users to perform interactive tasks on them.
The earlier autism spectrum disorder (ASD) is detected, the earlier children can receive intervention services, resulting in improved social, cognitive, and adaptive skills. Birth to 5 years is an especially critical time for identifying potential signs of delayed or unusual development that may indicate ASD. Tracking children's development can lead to an earlier diagnosis, and the Centers for Disease Control and Prevention (CDC) provides developmental monitoring tools for this through its ‚ "Learn the Signs. Act Early" program.
Came From Nothing is an interactive documentary that chronicles the incredible life story of Benjamin "Big Mouth Ben" Graham, an entrepreneur and motivational entertainer in Atlanta's Historic Sweet Auburn community. Big Mouth Ben overcame 17 years of addiction and homelessness on Auburn Avenue to open, together with his wife Tanya, a convenience store just two blocks from the same bridge under which he once slept.
Campus Tour is an augmented reality experience of Georgia Tech's campus. Once the channel is loaded in Argon, a standards-based Augmented Reality (AR) web browser developed by the Augmented Environments Lab. The tour gives information to users through text, pictures and videos. Stops on the tour are panoramic images.Within the panoramas are points of interests that once clicked reveal more information about their topic. Campus Tour allows users to remotely enjoy the beauty of campus or to learn more about Tech while on campus.
College students encounter many challenges in the pursuit of their educational goals. When these challenges are prolonged, they can have drastic consequences on health and on personal, social, and academic life. Our multi-institution project, called CampusLife, conceptualizes the student body as a quantified community to quantify, assess, infer, and understand factors that impact well-being.
CampusVR is a Virtual Reality sandbox. It's purpose is to help visualize spatial data and review IMAGINE Lab's 3D assets such as models of a campus and vegetation.   
Captioning on Glass is an on-going project creating an app for Google Glass with a companion Android phone app to assist the hard-of-hearing in everyday conversations. We are also working on another version of this app, "Translation on Glass", which will add the ability to translate between English and another language.
Healthcare big data is being widely touted as a potential resource for curbing costs and improving outcomes. However, numerous challenges remain for leveraging this data to its full potential. In this position paper, we identify the difficulties that characterize clinical data, based on our experiences working with pediatric asthma data from Children's Healthcare of Atlanta.
The Content Aggregation System for Election Observation (CASE) will aggregate real-time election observation data from formal observer missions and social media sources. Our new system, combining the power of crowdsourced data from social media with the precision of formal observers in the field, will create a first-ever fully integrated monitoring system. Simple technical interfaces will allow users to share particular information in real-time while still maintaining necessary data security and privacy.
