Emotional states are a core element for well-being, and social communication and interactions. Therefore, a positive affective state when interacting with a product or service is a signal of design success. Emotional states consist of a felt affect triggered or elicited by a particular stimulus. These stimuli can be either endogenous, e.g., a memory; or exogenous, e.g., the smile of another person. Emotions vary within an instant, and a single stimulus might cause several emotions or a blend of them. Emotions are dynamically inter-related responses, including bodily changes such as facial expressions, posture, and other autonomic changes. Finding clear signatures on the intricate relationship between body changes and subjective experiences is one of the major challenges in affective science. It is still under debate whether bodily changes precede or follow the subjective experience of emotion. Currently, experience sampling is done mainly through self-report. However, self-report might be biased or interrupt the user experience. Bodily changes can provide an alternative measurement with higher temporal resolution. However, many of these cues can also be controlled voluntarily, and therefore have the same biases as self-report. In this talk, I would like to present my work with regards to experience sampling, and to discuss in which situations one method would be preferred over another.
