People increasingly rely on visual representations of information to explore and make sense of data. However, people have inherent biases that often lead to errors and inefficiencies in the decision making process. The goal of our research is to help people make better decisions while exploring and analyzing data using visualizations. We introduce computational methods for quantifying an analyst’s biases based on their interactions in the visualization. Using that information, we illustrate ways to modify or design new visualization systems that mitigate biased decision making.
Data visualization can be an important guiding force in scientific debates and casual discussions alike. Bringing data visibly into the world can inform and bring attention to critical issues, as well as help us develop a more personal relationship with the data. This project aims to promote awareness and stimulate discussion about climate change through visualizing personal carbon footprint data on clothing. It explores the placement of visualizations in the social sphere, as well as revealing unseen individual and systematic responsibility for carbon emissions.
Visualizing sets to reveal relationships between constituent elements is a complex representational problem. Recent research presents several automated placement and grouping techniques to highlight connections between set elements. However, these techniques do not scale well for sets with cardinality greater than one hundred elements. We present OnSet, an interactive, scalable visualization technique for representing large-scale binary set data.
A few Fridays ago, the Public Design Workshop (PDW) led a Design and Policy Jam with the Westside Atlanta Land Trust (WALT) Program. WALT's mission is “to organize the community's power for self-determination; to serve and preserve in-place residents, small business owners, and their successive generations in redeveloping areas.” The jam session supported this mission by tasking participants with researching and producing an argument for a city-wide community land trust (CLT) policy.
Westside Soul is an interactive installation that was displayed at the Historic Westside Cultural Arts Council's Black History Month Celebration. The installation displays videos of westside residents discussing issues in their community and allows viewers to add new responses through text and video. The installation is part of on ongoing partnership with the westside to explore the use of mobile and social computing and digital media to connect community members and instigate alternate forms of civic engagement.
The news is the source citizens turn to in order to gain accurate information about the current events of the world. Unfortunately, a large number of trusted news sources are the worst perpetrators of bias; effectively skewing the public's perception of important material. "Who Told it How" is a web-based interactive visualization that displays various elements of the Wendy Davis abortion filibuster, as written in articles by four major news syndicates, in order to expose bias and provide perspective.
Our project on the human rights of Indian farmers. It is estimated that more than a quarter of a million Indian farmers have committed suicide in the last 16 years—the largest wave of recorded suicides in human history. By immersing the user in a rural farm in India, our goal is to foster understanding reinforced by dramatically motivated actions to express the dire living conditions and desperation of the farmers and their families.
A virtual reality experience in a dystopian world. With Love, Thunderbird is the story of a woman, nick-named Thunderbird, Peter and the struggles they face living in a society ruined by an unsuccessful coup and a string of useless ‘presidents’ who only accomplished increasing the inflation and unemployment rates. You play as Peter, navigating your way through this new world with your small robotic bird guide, with one simple goal: get medicine for Thunderbird.
We present a qualitative inquiry through the lens of feminist human-computer interaction (HCI) into women's perceptions of personal safety in New Delhi, India. Since a brutal gang-rape incident in December 2012 that received global attention, the Indian government has issued a mandate to implement a panic button on every new phone by 2017. We draw on interview and survey data to examine women's reactions to the mandate as well as what factors influence their perceptions of safety, both positively and negatively.
Worked Examples and Sub-goal Labeling: Impacts on Learning
Procedural instructions and worked examples have been shown to be effective learning aids in science, technology, engineering, and mathematics (STEM) learning materials. Procedural instructions are texts that describe a general method to reach a goal, while worked examples demonstrate how to apply this method to a specific instance. Research supporting the use of advanced organizers predicts that if learners see the worked example first, they can develop a basis for the problem-solving procedure.
Wristwash: towards automatic handwashing assessment using a wrist-worn device
Washing hands is one of the easiest yet most effective ways to prevent spreading illnesses and diseases. However, not adhering to thorough handwashing routines is a substantial problem worldwide. For example, in hospital operations lack of hygiene leads to healthcare associated infections. We present WristWash, a wrist-worn sensing platform that integrates an inertial measurement unit and a Hidden Markov Model-based analysis method that enables automated assessments of handwashing routines according to recommendations provided by the World Health Organization (WHO).
Through this interaction we aim to see if doing physical movements in a virtual space, coupled with a peaceful environment, can help users destress. The interactor enters a mystical fairy land when suddenly he/she sees a flash of light hurling towards the ground. The flash of light injures one of the 5 fairies in the scene. The injured fairy falls down, upon being hit by the light, and can no longer fly. The other fairies in the scene ask for the interactor's strength to help them heal the injured fairy.
ZEUSSS or Zero Energy Ubiquitous Sound Sensing Surface allows physical objects and surfaces to be instrumented with a thin, self-sustainable material, giving rise to revolutionary applications such as interactive walls, localization of sound sources and people, surveillance via audio, contextualization and safer authentication services.
