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 introduce Bit Whisperer, an ad-hoc short-range wireless communication system that enables "walk up and share" data transmissions with "good enough" security.
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.
Designing a curriculum builder that provides curated resources to learning the fundamentals of visual design
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.
