Developing Intelligent Facial Expression Identification Bot for IoT Using Azure and Power BI

In previous chapters, we have gone through the concepts of Bot Framework and Cognitive Services, such as LUIS, the linguistic service, and so on that are involved in developing and publishing bot applications. In this chapter, we will mainly focus on integrating IoT, the bot, and Power BI and see how can we leverage the power of bots and Cognitive Services in IoT. Here, we will develop an IoT application that will capture photos from a USB camera connected to the Raspberry Pi, then process it using the Face API and Emotion API of Cognitive Services to identify facial expressions. Once it completes the processing and identifies the face and emotional expression, the IoT application then sends it to the Facial Expression and Identification bot and also to Power BI to show reports.
