This new wave of research considers users' emotions explicitly to design interactive artifacts with the ability of estimating and responding to their users' emotional states. To this end, researchers have looked for a reliable means to elicit emotions in research settings. An experimental approach to elicit emotions originates from either considering emotion as an independent variable that contributes to a phenomenon, or as an outcome. Regardless of the motivation for studying emotion, in this chapter we explain the most reliable emotion elicitation techniques. Some of the techniques are more common in the clinical environments while others are used in experimental designs, especially in HCI research. This chapter will help researchers, designers, and practitioners find the most appropriate technique for their experimental settings.
