Comparing perspectives around human and technology support for contact tracing

Various contact tracing approaches have been applied to help contain the spread of COVID-19, with technology-based tracing and human tracing among the most widely adopted. However, governments and communities worldwide vary in their adoption of digital contact tracing, with many instead choosing the human approach. We investigate how people perceive the respective benefts and risks of human and digital contact tracing through a mixed-methods survey with 291 respondents from the USA. Participants perceived digital contact tracing as more benefcial for protecting privacy, providing convenience, and ensuring data accuracy, and felt that human contact tracing could help provide security, emotional reassurance, advice, and accessibility. We explore the role of self-tracking technologies in public health crisis situations, highlighting how designs must adapt to promote societal beneft rather than just self-understanding. We discuss how future digital contact tracing can better balance the benefts of human tracers and technology amidst the complex contact tracing process and context.
