This IDC study provides a five-year forecast for the worldwide smart home device market."The worldwide smart home device market continues to lay down the foundation for growth in future years," points out Ramon T. Llamas, research director for IDC's Consumer Internet of Things (IoT) research program. "The past several years have been about introducing devices and experiences while earning acceptance among consumers. This shall continue, and in the next years, we anticipate continued innovation to promote device interoperability, communication, and the surfacing of new information that will collectively guide and change the experience. Moreover, the addition of smart assistants (SAs) in more devices will slowly erode the barriers of adoption, making it easier for consumers to understand the value that these devices bring into the household."
