Action 1: User eXperience laboratory within HCI group

UX lab will be used to assess emotional, cognitive and perceptual reactions to mixed and real environments using psychophysiological, behavioural and subjective responses from users.

Example projects: •! Aesthetics of implicit interaction [methodology

development] •!Hyperscanning studies on group decision making

[group evaluation] •!Neuro- and biofeedback applications [prosocial

behavior training]

Action 2: Dedicated courses within MSc programmes

Project based courses within HCI or Digital Learning Games programmes where students will work together using physiology-based interaction for designing new applications for health, well-being and entertainment

Example projects: •! Phenomenon of catharsis defined in physiological

terms •!Neuro and bio-feedback training in actors and

“Stanislavsky 2.0” •! Physiology-based interaction patterns vocabulary,

minimal experience units or "cognemes"
