Current Research and Scholarly Interests
In my lab we have four key areas of study: mindful commute, subtle interventions, sensorless sensing, and precise mental states. Our projects aim to design not only useful and efficient wellbeing interventions, but also passive behavioral and affective sensors.
Every couple of days, humanity generates more data than all the data that was generated until 2013. Sensorless sensing is a provocative term and approach focused on repurposing many existing behavioral data streams to passively measure and study affect, stress, behavior, wellbeing and mental health biomarkers.
Auto-nomic: Turning the car into an affective sensor.
PeriStress: Peripherals and furniture as stress sensors.
We use human-centered design to develop affordable and ecologically valid interventions aimed at dramatically increasing adoption and engagement of wellbeing behaviors. We leverage cyber and physical personal spaces to deliver micro or slow interventions that do not distract or interrupt the user.
PopBots: an "army" of tiny chatbots for stress management.
UnDosTress: User-driven micro intervention authoring.
PopTherapy: Repurposing popular media into coping strategies.
Ultra Slow Show: Slow changing peripherals & furniture.
Calm Calm: Imperceptible modification of biorhythms.
Fiat Lux: Urban wellbeing interventions.
Every day, 50 Million Americans spend close to one hour per day commuting by car. We teamed up with Prof. James Landay's HCI lab to design interventions that help manual and autonomous car commuters feel energized to be productive in the morning, and wind down to socialize and sleep better in the evening.
Hapty Seat: Breathing & movement interventions for commuters.
Cool ReMix: Calming & mindful mixed reality in the car.
Fast & Furious: Detecting stress with a steering wheel.
PRECISE MENTAL STATES
Psychiatry is undergoing a major revolution with the advent of personal technology. We are part of a multi-disciplinary team led by Prof. Zhenan Bao, creating the Mentaid, a skin-like patch aimed at sensing cortisol from sweat and other biomarkers to measure and study longitudinally precise mental states.
Skin Wearability: Exploring use cases for skin-like wearables.
Mentaid Correlation Study: Lab & field sampling of biomarkers.

Evaluating In-Car Movements in the Design of Mindful Commute Interventions
Journal of Medical Internet Research (JMIR)
The daily commute could be a right moment to teach drivers to use movement or breath towards improving their mental health. Long commutes, the relevance of transitioning from home to work, and vice versa and the privacy of commuting by car make the commute an ideal scenario and time to perform mindful exercises safely. Whereas driving safety is paramount, mindful exercises might help commuters decrease their daily stress while staying alert. Increasing vehicle automation may present new opportunities but also new challenges.This study aimed to explore the design space for movement-based mindful interventions for commuters. We used qualitative analysis of simulated driving experiences in combination with simple movements to obtain key design insights.We performed a semistructured viability assessment in 2 parts. First, a think-aloud technique was used to obtain information about a driving task. Drivers (N=12) were given simple instructions to complete movements (configural or breath-based) while engaged in either simple (highway) or complex (city) simulated urban driving tasks using autonomous and manual driving modes. Then, we performed a matching exercise where participants could experience vibrotactile patterns from the back of the car seat and map them to the prior movements.We report a summary of individual perceptions concerning different movements and vibrotactile patterns. Beside describing situations within a drive when it may be more likely to perform movement-based interventions, we also describe movements that may interfere with driving and those that may complement it well. Furthermore, we identify movements that could be conducive to a more relaxing commute and describe vibrotactile patterns that could guide such movements and exercises. We discuss implications for design such as the influence of driving modality on the adoption of movement, need for personal customization, the influence that social perception has on participants, and the potential role of prior awareness of mindful techniques in the adoption of new movement-based interventions.This exploratory study provides insights into which types of movements could be better suited to design mindful interventions to reduce stress for commuters, when to encourage such movements, and how best to guide them using noninvasive haptic stimuli embedded in the car seat.

INQUIRE Tool: Early Insight Discovery for Qualitative Research
Proceeding CSCW '17 Companion Companion of the 2017 ACM Conference on Computer Supported Cooperative Work and Social Computing.
This demo presents an instance of Inquire, a tool designed to support qualitative researchers in the early stages of research. The tool enables the search over millions of users' records to extract early insights to aid in the formulation of research strategies. The tool presents the work described in the Inquire paper by Paredes, et. al.  in this demo we show how queries become a part of the inductive process, enabling researchers to try multiple ideas while gaining intuition and discovering less-obvious insights. We leverage LiveJournal (LJ) as a rich source of public posts, and Google News (GN) embeddings which link formal language (e.g. "reminiscence triggers") with colloquial expressions (e.g. "music brings back memories"). Using our tool, we elicit the interplay between tool and user to enhance qualitative and social research opportunities.
Design Principles for the Conceptualization of Games for Health Behavior Change.
Gamification Workshop @ CHI 2013.
This paper presents a list of principles that can be used to conceptualize games for health behavior change. These principles are derived from lessons learned after teaching two design-centered courses on Gaming and Narrative Technologies for Health Behavior Change. Course sessions were designed to create many rapid prototypes on specific topics coupling behavior change theory with iterative human-centered and game design techniques. The design task had two broad goals: 1) designing efficacious technologies, with an emphasis on short-term behavior change and 2) using narratives and game dynamics as vehicles for increased engagement and long-term sustained change. Example prototypes resulting from this design approach are presented.
Sensor-less Sensing for Affective Computing and Stress Management Technology.
This paper describes our vision on what should be the research around sensing and adaptive interventions to make affective computing and stress management technology pervasive and unobtrusive. With the use of common computer peripherals and mobile computing devices as affect sensors, personalized and adaptive intervention technologies can be developed. Furthermore, physiological sensing can be performed without the introduction of extraneous factors such as wearable devices or focused software. Different methods for sensing and complementary adaptable interventions and interactions are described and proposed. We show initial lab evidence of the use of a computer mouse in the detection of stress.
CalmMeNow: exploratory research and design of stress mitigating mobile interventions
Proceeding CHI EA '11 CHI '11 Extended Abstracts on Human Factors in Computing Systems.
This paper describes design explorations for stress mitigation on mobile devices based on three types of interventions: haptic feedback, games and social networks. The paper offers a qualitative assessment of the usability of these three types of interventions together with an initial analysis of their potential efficacy. Social networking and games show great potential for stress relief. Lastly, the paper discusses key findings and considerations for long-term studies of stress mitigation in HCI, as well as a list of aspects to be considered when designing calming interventions.
