Projects

This project involves the development and evaluation of a mobile content delivery system. Using small, unplanned moments throughout the day, we endeavor to increase the ability of hearing parents with deaf children to recognize and produce American Sign Language vocabulary.
Smog Solver is an environmental web simulation of how the smog problem can be possibly solved in Beijing. The purpose of this simulation is to educate users about the major causes of smog in Beijing and the solutions through replays. According to the final evaluation, my simulation could effectively help users learn ~92% of the major causes of smog and increase their knowledge of the solutions.
Text messaging is a functionality that has been widely used in user studies due to its presence in smartphones and feature phones alike. However, the ability to use cell phones for data collection has been limited to researchers that have programming abilities. We present SMSPress, a web-based SMS management system that allows non-technical users to configure SMS studies, and schedule text messages for delivery to participants via a web-interface. We establish the requirements for such a system and present the results from two case studies.
We are developing technological platforms, human and social processes, and the underlying creative abilities to leverage social media and digital networks to enhance democracies especially in Africa. Our current work has focused on participation in and monitoring of elections while future work will expand that frame seeking to foster broader and deeper civic engagement, especially among youth, the promotion of government accountability and efficacy, and the constructive creative ability to hack democracy.
Social Media is changing our world. Traditional narratives paint a picture of many-to-many democratization of information--making ideas, opinions, education, and knowledge available to many people in many places at any time. This research examines whether this is actually the case, especially in countries with a totalitarian government. Through an interview-based study of Cuban participants on social media, this project explores both the limitations and opportunities of cyber networks as tools for individuals to create collaborative narratives and affect social change.

Social TV is a mobile application that works in conjunction with watching TV. It is targeted to users who may be living in a new location and watch TV alone, or to users who want to increase the social aspect of watching TV. Through integration with Facebook, the mobile app presents a TV Feed where users can share information, such as screenshots, quotes and recommendations with other individuals in their network. The app has a TV chat feature, where users can engage in both synchronous and asynchronous chatting about what is occurring in the show of their choosing.
The SDX project is applying the principles of Software Defined Networking and Infrastructure to the problems of peering between network operators and service providers. This work seeks to overcome the traditional limitations of peering protocols such as BGP to enable operators and their customers to express rich, application-specific policies that facilitate the integration of cloud computing and virtualization into numerous applications.
Students in the Sonification Lab and Center for Music Technology designed Solar System Sonification, an auditory experience of the planets. Using non-speech audio to convey information, they built a musical model of the solar system. Planetariums typically rely on visuals with various levels of speech description, but have not explored using auditory cues to present information about space. Auditory displays, like the ones developed for Solar System Sonification, enable more immersive experiences and make information accessible to people with visual impairments.
SolidSketch is a solid modeling program that enables users to rapidly construct 3D models through sketch and multi-touch input. The interaction design principles of SolidSketch are based on the cognitive science theory of enaction. This paper uses the enaction theory as a lens to describe why the interaction designs of conventional CAD tools often fail to support early stages of the design process. We argue enactive interactions would support design creativity by enabling rapid iteration and continuous feedback throughout a flexible design exploration.
The Sonified Fantasy Sports project has been exploring various ways to add sounds to online (web or mobile apps) fantasy sports in an attempt to make a more immersive user experience while also adding to the accessibility of fantasy sports for visually impaired or print disabled users. After identifying information needs and various strategies employed by users (who ranged from beginners to power users) we were able to identify a hierarchy in which to present information about my team and players using sound.
Sound Happening is a collaborative music-making installation that allows several people to explore and create music in a space by playing with colorful bouncy balls. Using a webcam and Max/MSP, Sound Happening tracks each ball's location relative to the space to manipulate and trigger various samples, resulting in intriguing sound combinations that are constantly changing as the balls move.
