Advances in mobile computing offer the potential to change when, where, and how health interventions are delivered. Rather than relying on occasional in-clinic interactions, mobile health (mHealth) interventions may overcome constraints due to limited clinician time, poor patient adherence, and inability to provide meaningful interventions at the most appropriate time. Technological capability, however, does not equate with user acceptance and adoption. How then can we ensure that mobile technologies for behavior change meet the needs of their target audience? In this paper, we argue that overcoming acceptance and adoption barriers requires interdisciplinary collaborations, bringing together not only technologists and health researchers but also human-computer interaction (HCI) experts. We discuss the value of human-computer interaction research to the nascent field of mHealth and demonstrate how research from HCI can offer complementary insights on the creation of mobile health interventions. We conclude with a discussion of barriers to interdisciplinary collaborations in mobile health and suggest ways to overcome them.
KeywordsHuman-computer interaction, Information technology, mHealth, Mobile technology Human-computer interaction is an interdisciplinary area of research and practice, drawing upon intellectual traditions of several disciplines including human factors, computer science, information systems, psychology, sociology, and visual design. For several decades, Human-computer interaction (HCI) research and practice has focused on designing human-centered technologies that fit into the everyday needs and routines of the people who use them [1], often referred to as user-centered design [2]. With this design philosophy, user needs are considered throughout the design of a technology-from initial requirements gathering to end stages of technology development. Rather than focusing on health outcomes or technical capabilities, a usercentered design approach provides insight into usability, usefulness, and fit of a technology into daily life. This approach can answer important questions on why technologies work in a given environment for a given set of users or why they fail to engage a target audience. In short, humancomputer interaction research can offer complementary insights into how people integrate smartphones, sensor networks, and social networks into their health behavior change efforts, as well as insight into how to design behavior change technologies such that they are more effective.Within HCI, there has been a recent movement to study the roles in which sensors, social networks, smartphones, and other technologies can take in behavior change related to water intake [3,4], diet [5][6][7][8][9][10][11], physical activity [12][13][14][15][16][17][18][19][20][21][22], healthy sleep behaviors [23,24], and chronic disease management [25][26][27][28][29][30]. Yet, there is a little overlap between HCI and the health sciences in these endeavors. This article not only describes the reasons for la...
