We explored the social acceptability and user experience of wearable form factors as a portable option for Bright Light Therapy (BLT). BLT remains the predominant therapy for Seasonal Affective Disorder despite a non-compliance rate of ~70% commonly attributed to the inconvenience of prolonged daily sitting in front of light boxes. To date, attempts to address convenience using wearable/portable light treatment options have been met with limited success for nuanced reasons (i.e., stigma, efficacy,...

Diversifying participation in crowd work can benefit the worker and requester. Increasing numbers of older adults are online, but little is known about their awareness of or how they engage in mainstream crowd work. Through an online survey with 505 seniors, we found that most have never heard of crowd work but would be motivated to complete tasks by earning money or working on interesting or stimulating tasks. We follow up results from the survey with interviews and observations of 14 older adults...

While email has been shown to be beneficial in the workplace, studies have reported that extensive email use can bring costs. In this study we investigate exactly how time spent on email might be related to perceived productivity and stress in the workplace. We conducted a mixed methods approach using computer logging, biosensors and daily surveys with 40 information workers in their in situ workplace environments for two workweeks. We found that the more time employees spent on email, the...

LASIK (Laser-Assisted in SItu Keratomileusis) surgeries have been quite popular for treatment of myopia (nearsightedness), hyperopia (farsightedness) and astigmatism over the past two decades. In the past decade, over 10 million LASIK procedures had been performed in the United States alone with an average cost of approximately $2000 USD per surgery. While 99% of such surgeries are successful, the commonest side effect is a residual refractive error and poor uncorrected visual acuity (UCVA). In this...

Positive wellbeing in the workplace is tied to better health. However, lack of wellbeing in the workplace is a serious problem in the U.S, is rising continually, and can lead to poor health conditions. In this study we investigate factors that might be associated with workplace wellbeing. We report on an in situ study in the workplace of 40 information workers whose mood was tracked for 12 days. We used a mixed-methods study using Fitbit actigraphs to measure sleep and physical activity,...

Various wearable sensors

capturing body vibration, jaw movement,

hand gesture, etc., have shown promise in detecting when one is

currently eating. However, based on existing literature and user

surveys conducted in this study, we argue that a Just-in-Time eating

intervention, triggered upon detecting a current eating event,

is sub-optimal. An eating intervention triggered at “About-to-Eat”

moments could provide users with a further opportunity to...

Applying machine learning to a problem which involves medical, financial, or other types of sensitive data, not only requires accurate predictions but also careful attention to maintaining data privacy and security. Legal and ethical requirements may prevent the use of cloud-based machine learning solutions for such tasks. In this work, we will present a method to convert learned neural networks to CryptoNets, neural networks that can be applied to encrypted data. This allows a data owner to...

People can have experiences through video calls that are otherwise inaccessible. For example, someone who cannot leave the home may wish to experience visiting the zoo. We present TeleTourist, a system that uses video calls with strangers to share experiences for people with mobility restrictions. We designed TeleTourist to enhance immersion and personalization, as well as help balance the relationship between participants of the video calls. We discuss features we have implemented or envisioned for...

Dataflow-style workflows offer a simple, high-level programming model for flexible prototyping of scientific applications as an attractive alternative to low-level scripting. At the same time, workflow management systems (WFMS) may support data parallelism over big datasets by providing scalable, distributed deployment and execution of the workflow over a cloud infrastructure. In theory, the combination of these properties makes workflows a natural choice for implementing Big Data processing pipelines,...

Biological Data Science is an emerging field facing multiple challenges for hosting, sharing, computing on, and interacting with large data sets. Privacy regulations and concerns about the risks of leaking sensitive personal health and genomic data add another layer of complexity to the problem. Recent advances in cryptography over the last 5 years have yielded a tool, homomorphic encryption which can be used to encrypt data in such a way that storage can be outsourced to an untrusted cloud,...

Technology workers are often stereotyped as being socially awkward or having difficulty communicating, often with humorous intent; however, for many technology workers with atypical cognitive profiles, such issues are no laughing matter. In this paper, we explore the hidden lives of neurodiverse technology workers, e.g., those with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and/or other learning disabilities, such as dyslexia. We present findings from interviews...

Assessing the effect of a health-oriented intervention by traditional epidemiological methods is commonly based only on population segments that use healthcare services. Here we introduce a complementary framework for evaluating the impact of a targeted intervention, such as a vaccination campaign against an infectious disease, through a statistical analysis of usergenerated content submitted on web platforms. Using supervised learning, we derive a nonlinear regression model for estimating the...

A fundamental question in biology is how cells change into specific cell types with unique roles throughout development. This process can be viewed as a program prescribing the system dynamics, governed by a network of genetic interactions. Recent experimental evidence suggests that these networks are not fixed but rather change their topology as cells develop. Currently, there are limited tools for the construction and analysis of such self-modifying biological programs. We introduce Switching Gene...

Despite a long history and a large volume of affective research, measuring affective states is still a non-trivial task that is complicated by numerous conceptual and methodological decisions that the researcher has to make. We suggest that inconsistent results reported in some areas of research can be partially explained by the choice of measurements that capture different manifestations of affective phenomena, or focus on different elements of affective processes. In the present study we examine one...

Accurate and timely assessment of collective emotions in the workplace is a critical managerial task. However, perceptual, normative, and methodological challenges make it very difficult even for the most experienced organizational leaders. In this paper we present a MoodTracker - a technological solution that can help to overcome these challenges, and facilitate a continuous monitoring of the collective emotions in large groups in real-time. The MoodTracker is a program that runs on any PC device, and...

We developed a feedback-loop, user-tailored advice system to provide stress interventions and advice about improving sleep, diet, and exercise habits at the workplace. Thirty participants joined a 2 week study: in the first week, we collected their behaviors about sleep, diet, exercise and stress levels using Fitbit and surveys. During the second week we continued monitoring, and based on the participants’ measurements in the previous days, we also provided interventions and advice during the workday,...

Purpose

Disordered eating behavior—dieting, laxative use, fasting, binge eating—is common in college-aged women (11%–20%). A documented increase in the number of young women experiencing eating psychopathology has been blamed on the rise of engagement with social media sites such as Facebook. We predicted that college-aged women's Facebook intensity (e.g., the amount of time spent on Facebook, number of Facebook friends, and integration of Facebook into daily life), online physical appearance...

Ideally, if enough were known about all the variables affecting heart rate, the time of the next beat could be known. Of course this means knowing: the environment e.g. temperature, air density, wind, air quality; activity level e.g. sleeping, sitting, standing, walking, running, biking, rowing; diet and digestive loads including stimulants; physical health including allergies, sicknesses, and chronic ailments e.g. asthma, bronchitis; and all the kinds and levels of stress. I’ve observed all of these...

Syndromic surveillance refers to the analysis of medical information for the purpose of detecting outbreaks of disease earlier than would have been possible otherwise and to estimate the prevalence of the disease in a population. Internet data, especially search engine queries and social media postings, have shown promise in contributing to syndromic surveillance for in uenza and dengue fever. Here we focus on the recent outbreak of Ebola Virus Disease and ask whether three major sources of Internet...

Crowd-powered systems that help people are difficult to scale and sustain because human labor is expensive and worker pools are difficult to grow. To address this problem we introduce the idea of social microvolunteering, a type of intermediated friendsourcing in which a person can provide access to their friends as potential workers for microtasks supporting causes that they care about. We explore this idea by creating Visual Answers, an exemplar social microvolunteering application for...

While distractions using digital media have received

attention in HCI, understanding engagement in workplace

activities has been little explored. We logged digital activity

and continually probed perspectives of 32 information

workers for five days in situ to understand how attentional

states change with context. We present a framework of how

engagement and challenge in work relate to focus, boredom,

and rote work. Overall, we find more focused...
