Abstract

Psychophysiological assessment in the context of virtual environments is a promising means for benchmarking the efficacy and ecological validity of virtual reality scenarios. When applied to human-computer interaction, psychophysiological and affective computing approaches may increase facility for development of the next generation of human-computer systems. Such systems have the potential to use psychophysiological signals for user-feedback and adaptive responding. As the composition of investigating teams becomes diverse in keeping with interdisciplinary trends, there is a need to review de-facto standards of psychophysiological response quantification and arrive at consensus protocols adequately addressing the concerns of basic researchers and application developers. The current paper offers a demonstration of the ways in which such consensus scoring protocols may be derived. Electromyographic eye-blink scoring from an immersion investigation is used as an illustrative case study.
