    A Circle of Friends: Persuasive Tools to Improve Heart Health
    (ACM, 2020-01) Sanders, Jamie; Glenn-Smith, Ina; Purnell, Tanjala S.; Martin-Hammond, Aqueasha; Charleston, Jeanne; Human-Centered Computing, School of Informatics and Computing
    Cardiovascular disease (CVD) is the leading causes of death in the United States and worldwide. While CVD risk factors are well-known and many can be changed with diet and exercise, more research is needed to understand how to design effective interventions that help patients reduce CVD risk. In this paper, we present the results of a content analysis of the Health Freedom Circle of Friends (COF) Walking Program, a community-based health program run by a public health non-profit that has been shown to reduce CVD risks. We examine the design to better understand the persuasive tools used as well as parts of the design that might benefit from a technological intervention.

    Comparing Older and Younger Adults Perceptions of Voice and Text-based Search for Consumer Health Information Tasks
    (2021) Bonilla, Karen; Gaitan, Brian; Sanders, Jamie; Khenglawt, Noami; Martin-Hammond, Aqueasha; BioHealth Informatics, School of Informatics and Computing
    The increased prevalence of voice search presents opportunities to address consumer challenges accessing online health information. However, it is essential to understand how users’ perceptions of voice affect their search processes for health information, concerns, and different scenarios for using voice for health information tasks. We conducted semi-structured interviews with 16 younger (18-25) and older (60-64) adult participants to understand and compare their perceptions of using voice and text-based search for non-health-related and health related tasks. While most participants preferred traditional text search, younger adults were not inclined to use voice search for health information due to concerns about privacy, credibility, and perceived efficiency in filtering results. Older adults found voice search potentially beneficial for reducing manual query generation burdens; however, some were unsure of how to use the technology effectively. We provide a set of considerations to address concerns about voice search for health information tasks in the future

    A Question of Access: Exploring the Perceived Benefits and Barriers of Intelligent Voice Assistants for Improving Access to Consumer Health Resources Among Low-Income Older Adults
    (Sage, 2020-12-29) Nallam, Phani; Bhandari, Siddhant; Sanders, Jamie; Martin-Hammond, Aqueasha; Human-Centered Computing, School of Informatics and Computing
    Intelligent voice assistants (IVAs) such as Amazon Echo and Google Home present a promising opportunity to improve access to consumer health information and resources for older adults. However, researchers know little about older adults' opinions of using IVAs for these potentially critical tasks, particularly those with already limited access. In this paper, we explore older adults' views about IVAs for consumer health and wellness information with the goal of better understanding what they envision as benefits and barriers of using such technology in the future. We shared an IVA prototype with ten older adults (60 years of age or older). We interviewed them about how a similar system might impact their access to consumer health information. Participants saw the potential for IVAs to improve their search experiences and support them with other health tasks. However, participants were also concerned about adopting an IVA for health due to access barriers, confidentiality risks, and concerns about receiving trusted information. Based on our findings, we discuss considerations for designing IVAs for underserved, older adult populations.
