The internet of things (IoT) is a chance to provide users with pervasive environments in which they can interact naturally with the environment. Multimodal interaction is the domain that provides this naturalness by using different senses to interact. However, the IoT context requires a specific process to create such multimodal systems. In this article, we investigate the process of creating multimodal systems with connected devices as interaction mediums, and provide an analysis of the existing tools to complete this process. We discuss tools that could be designed to support the creation process when the existing ones are not sufficient.
