Personification and Parenting of Amazon Alexa

User Empowerment Lab, University of Washington Information SchooL

Advisor: Dr. Alexis Hiniker and PhD student Erin Beneteau

This project studies interaction and parenting behaviors around Amazon Alexa, with a special focus on the personification of the smart home assistant and how it is used in families. I performed literature review on social computing and mindlessness, and conducted data analysis on over 150 audio captures to understand and identify usage behaviors of parent and children. By doing so, we hope to understand families’ perception in interaction with Amazon Alexa and how home assistants can be utilized in supporting child development and family activities. Currently, I am working on paper submission to CHI 2019 Student Research Competition.

SOARING Project - Supporting Health Information Management for Older Adults

Computing for Healthy Living & Learning (CHiLL) Lab, University of Washington Department of Human Centered Design and Engineering (HCDE)

Advisor: Dr. Julie Kientz and PhD student Dawn Sakaguchi-Tang

SOARING Project focus on Studying Older Adults & Researching Information Needs and Goals. Working in a multidisciplinary research team with expertise ranges from geriatrics and health services to medical informatics and consumer health, our goal is to better understand how older adults manage personal health information and the role caregivers play in these practices. My focus in the team is evaluating connected personas for health information practices of older adults and stakeholders. Through design sessions with designers, I gain insights to inform the design of supportive tools that meet the information management needs of older adults and supportive stakeholders. Currently, I am working on a paper submission for Design Interactive Systems Conference (DIS) 2019.

Preventing Unintended and Malicious Audio Capture on Android Devices

User Empowerment Lab, University of Washington Information SchooL

Advisor: Dr. Alexis Hiniker

This project aims to develop design guidance for mobile operating systems developers seeking to protect users from malicious and unintended audio capture. We have conducted over 30 interviews and focus groups to study how Android users conceive of their smartphones’ audio capture behaviors. By studying people’s perceptions and then designing and evaluating a device-wide interface to alert users to audio capture, we hope to improve the industry’s ability to empower users to protect themselves. In the future, we will design a usable security layer for Android devices that brings users’ mental models of audio permissions into alignment with the system implementation and real-time audio capture activity.

Conversational Agent for Collecting Patient Information in Hospital Waiting Rooms

Department of Human Centered Design and Engineering (HCDE), University of Washington

Advisor: Dr. Gary Hsieh and PhD student Rafał Kocielnik

Currently, patient’s information is often gathered with paper and pen surveys as they wait in waiting rooms. However, response rates are low. More data from patients are needed to understand low-income patients’ needs and offer tailored services to address these needs. This research explored the use of conversational agents to facilitate this data collection. In this project, we collaborated with Harbor - UCLA Medical Center on prototyping the user interaction, visual interface and the conversation dialogs. A working prototype of conversational agent is created to understand if such an agent increase survey participation and improve the quality of responses. Future work includes understanding what tradeoffs between voice- and text-based interactions in this context.a

Parental Involvement on Children’s School Performance

University of Washington Information SchooL

Advisor: Dr. Katie Davis and PhD student Benjamin Xie

This project aims to reveal patterns and trends existing with single parents, that have a significant impact on child well-being through adolescence. Through quantitative data analysis on the open source Fragile Families Dataset released by Princeton University, we studied correlation between parenting behaviors and their child’s school performance using data science methodologies. The Fragile Families Dataset is a 15-year longitudinal study following nearly 5,000 families. The goal of our analysis is to give parents information on how they can help their children improve academically. A final paper, poster and GitHub Wiki is created for showcasing the findings.
