With the evolving Internet of Things (IoT), the number of smart devices we interact in our day-to-day life has significantly increased. The nature of human interaction with these devices must be perceived, because too much complexity could lead to the risk of IoT appearing unattractive for users or the system losing its efficiency, regardless of its potential. Therefore, it is important to address problems in Human Device Interactions to provide a high-quality User Experience (UX) in the emerging IoT. This paper proposes a roadmap to address the complexities associated with human smart device (sensor or actuator) interaction through a methodology that incorporates context awareness in Augmented Reality (AR) using semantic Web technologies. Further, we analyse the use of Natural User Interfaces (NUI), such as hand gestures and gaze, to provide noninvasive and intuitive interaction in optimising the user experience
