A foundational review of psychophysiology for human-computer interaction provides a framework of terms, describes 10 physiological signals, and includes a systematic review of multimodal studies.
This primer provides a foundational overview of psychophysiological signals and analysis techniques for applications in human-computer interaction.
Supplies essential terminology and signals for psychophysiology in HCI; leaves open rigorous multimodal validation in applied settings.
Digital monitoring of physiological signals can allow computer systems to adapt unobtrusively to users, so as to enhance personalised ‘smart’ interactions. In recent years, physiological computing has grown as a research field, and it is increasingly considered in diverse applications, ranging from specialised work contexts to consumer electronics. Working in this emerging field requires comprehension of several physiological signals, psychophysiological states or ‘indices’, and analysis techniques. The resulting literature encompasses a complex array of knowledge and techniques, presenting a clear challenge to the practitioner. We provide a foundational review of the field of psychophysiology to serve as a primer for the novice, enabling rapid familiarisation with the core concepts, or as a quick-reference resource for advanced readers. We place special emphasis on everyday human–computer interface applications, drawing a distinction from clinical or sports applications, which are more commonplace. The review provides a framework of commonly understood terms associated with experiential constructs and physiological signals. Then, 12 short and precisely focused review chapters describe 10 individual signals or signal sources and present two technical discussions of online data fusion and processing. A systematic review of multimodal studies is provided in the form of a reference table. We conclude with a general discussion of the application of psychophysiology to human–computer interaction, including guidelines and challenges.

Cowley et al. (2016) conducted a review in Human-computer interaction and psychophysiology. Psychophysiological monitoring was evaluated. A foundational review of psychophysiology for human-computer interaction provides a framework of terms, describes 10 physiological signals, and includes a systematic review of multimodal studies.
