Literature Review of Theory-Based Empirical Research Examining Consumers’ Adoption of IoT

The Internet of Things (IoT) is an international context that is in the process of massive development. The IoT has initiated new opportunities in the technological context and is one of the most central technological initiatives today. This study conducted a systematic review of the related literature examining theory-based empirical research on IoT adoption by consumers. Forty-three studies were identified between 2011 and 2023 in 20 different countries, mostly Malaysia, Turkey and India. The studies have mostly examined IoT adoption in smart homes, IoT adoption in the retail service industry (consumer shopping), and IoT adoption in healthcare and fitness wearable devices. The main theory that was used to examine the consumer adoption of IoT was the Technology Acceptance Model (TAM). The most examined constructs that were found to be significant in relation to behavioural intention were perceived usefulness, perceived ease of use, and trust. This research provides theoretical implementations for future researchers who are interested in examining the IoT adoption of consumers in different countries and different technological contexts.
