Haitian Resiliency: A Case Study in Intermittent Infrastructure

Haitian Resiliency: A Case Study in Intermittent Infrastructure Cover Sheet

In 2010 Haiti experienced a catastrophic earthquake that destroyed a substantial amount of infrastructure in the capital of Port-au- Prince. Limited national resources and widespread poverty have made the rebuilding slow and piecemeal. Five years later that infrastructure is still unevenly repaired and maintained. Nevertheless, the Haitian people have, by necessity, continued to adapt in…

Cacophony: Building a Resilient Internet of Things

Cacophony: Building a Resilient Internet of Things cover sheet

The proliferation of sensors in the world has created increased opportunities for context-aware applications. However, it is often cumbersome to capitalize on these opportunities due to the difficulties inherent in collecting, fusing, and reasoning with data from a heterogeneous set of distributed sensors. The fabric that connects sensors lacks resilience and fault tolerance in the…

ICT4S 2029: What will be the systems supporting sustainability in 15 years

ICT4S paper cover

  Research is often inspired by visions of the future. These visions can take on various narrative forms, and can fall anywhere along the spectrum from utopian to dystopian. Even though we recognize the importance of such visions to help us shape research questions and inspire rich design spaces to be explored, the opportunity to…

Collapse Informatics and Practice: Theory, Method, and Design

Collapse Informatics and Practice: Theory, Method, and Design cover page

What happens if efforts to achieve sustainability fail? Research in many fields argues that contemporary global industrial civilization will not persist indefinitely in its current form, and may, like many past human societies, eventually collapse. Arguments in environmental studies, anthropology, and other fields indicate that this transformation could begin within the next half-century. While imminent…

Interchange: Bidding for green lights

Interchange: Bidding for green lights

In urban environments great effort is directed toward alleviating traffic including the design and implementation of complex software and hardware infrastructure. We introduce the idea of an auction-based mechanism for resolving vehicle intersections using a multi-way group auction mechanism. We propose a supporting infrastructure that has promise for increasing performance and responsiveness to dynamic traffic…

Efficiently Scaling up Crowdsourced Video Annotation

Efficiently Scaling up Crowdsourced Video Annotation: A Set of Best Practices for High Quality, Economical Video Labeling

We present an extensive three year study on economically annotating video with crowdsourced marketplaces. Our public framework has annotated thousands of real world videos, including massive data sets unprecedented for their size, complexity, and cost. To accomplish this, we designed a state-of-the-art video annotation user interface and demonstrate that, despite common intuition, many contemporary interfaces…

Augmenting Gesture Recognition with Erlang-Cox Models To Identify Neurological Disorders in Premature Babies

Augmenting Gesture Recognition with Erlang-Cox Models To Identify Neurological Disorders in Premature Babies

In this paper we demonstrate a Markov model based technique for recognizing gestures from accelerometers that explicitly represents duration. We do this by embedding an Erlang-Cox state transition model, which has been shown to accurately represent the first three moments of a general distribution, within a Dynamic Bayesian Network (DBN). The transition probabilities in the…

Assessment of Infant Movement with a Compact Wireless Accelerometer System

Assessment of Infant Movement with a Compact Wireless Accelerometer System

There is emerging data that patterns of motor activity early in neonatal life can predict impairments in neuromotor development. However, current techniques to monitor infant movement mainly rely on observer scoring, a technique limited by skill, fatigue, and inter-rater reliability. Consequently, we tested the use of a lightweight, wireless, accelerometer system that measures movement and…

Collapse Informatics: Augmenting the Sustainability & ICT4D Discourse in HCI

Collapse informatics: Augmenting the Sustainability & ICT4D Discourse in HCI cover sheet

Research in many fields argues that contemporary global industrial civilization will not persist indefinitely in its current form, and may, like many past human societies, eventually collapse. Arguments in environmental studies, anthropology, and other fields indicate that this transformation could begin within the next half-century. While imminent collapse is far from certain, it is prudent…

Massively Distributed Authorship of Academic Papers

Massively Distributed Authorship of Academic Papers

Wiki-like or crowdsourcing models of collaboration can provide a number of benefits to academic work. These techniques may engage expertise from different disciplines, and potentially increase productivity. This paper presents a model of massively distributed collaborative authorship of academic papers. This model, developed by a collective of thirty authors, identifies key tools and techniques that…

Audia

Whisper Analytics

Audia, formerly whisper.fm, was a start-up that I worked on with George Ruan and Sam Kaufman.  It was a very simple idea.  Instead of downloading a podcast, you could call in and listen to it over the audio channel of the phone.   It enabled you to get podcast content without a data plan.  If the…

Informing and performing: investigating how mediated sociality becomes visible

Informing and performing: investigating how mediated sociality becomes visible

In the human–computer interaction, computer supported cooperative work, and ubiquitous computing literature, making people’s presence and activities visible as a design approach has been extensively explored to enhance computer-mediated interactions and collaborations. This process has developed under the rubrics of “awareness,” “social translucence,” “social activity indicators,” “social navigation,” etc. Although the name and details vary,…

Involuntary Gesture Recognition for Predicting Cerebral Palsy in High-Risk Infants

Involuntary Gesture Recognition for Predicting Cerebral Palsy in High-Risk Infants

In this paper we describe a system that leverages accelerometers to recognize a particular involuntary gesture in babies that have been born preterm. These gestures, known as cramped-synchronized general movements are highly correlated with a diagnosis of Cerebral Palsy. In order to test our system we recorded data from 10 babies admitted to the newborn…

Efficiently Scaling Up Video Annotation with Crowdsourced Marketplaces

Efficiently Scaling Up Video Annotation with Crowdsourced Marketplaces

Accurately annotating entities in video is labor intensive and expensive. As the quantity of online video grows, traditional solutions to this task are unable to scale to meet the needs of researchers with limited budgets. Current practice provides a temporary solution by paying dedicated workers to label a fraction of the total frames and otherwise…

Twitter, Sensors and UI: Robust Context Modeling for Interruption Management

Twitter, Sensors and UI: Robust Context Modeling for Interruption Management

In this paper, we present the results of a two-month field study of fifteen people using a software tool designed to model changes in a user’s availability. The software uses status update messages, as well as sensors, to detect changes in context. When changes are identified using the Kullback-Leibler Divergence metric, users are prompted to…
