Abstract
There is no doubt that students’ emotional states influence their general well-being and their learning success. Although current advances of computer hardware and Artificial Intelligence (AI) techniques made it possible to include real-time emotion-sensing as one of the ways to improve students’ learning experience and performance, there are many challenges that might inhibit or delay the deployment and usage of emotional learning analytics (LA) in education. In this chapter, we will critically review the current state-of-the art of emotion detection techniques, analysis and visualisation, the benefits of emotion analysis in education and the ethical issues surrounding emotion-aware systems in education. Finally, we hope that our guidelines on how to tackle each of those issues can support research in this area.
