The Magic Circle of Games
antonioperezrio.es
“...the consequences of the activity are negotiable” (Juul, 2005)
Games as:“Cognitive-Emotional Integration Engines”?
Storytelling a significant feature of human culture
Meaning making is important in Health and Wellbeing (Narrative Medicine)
Games could help in health and wellbeing “Meaning Making” process
Hamlet on the Holodeck
“To rival the narrative richness of other media, then, a system of interactive storytelling must be able to stage both physical actions that change the fictional world and verbal acts that affect the minds of its inhabitants and motivate them to take action.”
(Ryan, 2009)
The Interactive Paradox
(Aylett & Louchart, 2004)
Integration of the unpredictable, bottom-up input of the user into a sequence of events that fulfills the top-down design conditions of narrativity
“On one hand the author seeks control over the direction of a narrative in order to give it a satisfactory structure. On the other hand a participating user demands the autonomy to act and react without explicit autho- rial constraint.”

Physiological Computing - Categories
Biofeedback
Biocybernetic adaptation
Brain–computer interfacing
Biofeedback
the controller of a system can control a given variable if information about that variable is made available to it
notion of humans being able to exert conscious influence over seemingly unconscious physiology
i.e. increasing “body awareness” - interoception
more highly developed in performers, kinaesthetic learners, artists?
Biofeedback examples
Biocybernetic Adaptation
Biocybernetic adaptation refers to the modification of system’s functionality or appearance based on the real-time measurement of psychophysiology.
Not biofeedback
Rather an adaptive system that responds to user’s changing psychophysiological state
e.g. fatigue, frustration
Game Adaptation example
Brain–computer interfacing
Channels for direct command and communication between psychophysiology and an output device (e.g. control of a cursor)
Main focus of BCI research has been to develop systems to help people with disabilities (e.g. spinal cord injuries)
Issues
extended training times
need to sit style - movement artifacts
BCI examples

Potential Physiological Variables
Outer surface of the Brain (electroencephalogram: EEG)
Skeletal Muscles (electromyogram: EMG)
Heart (electrocardiogram: ECG)
Eyes (electro-oculogram: EOG, pupillometry: eye tracking)
Blood pressure
Respiratory patterns
Skin conductance (galvanic skin response: GSR)
Platform + Sensors
“Cheaper” kit
Do No Harm...
Be Safe (Electrical Safety, Tripping Hazards)
Don’t screw up your subjects (players)
Mrs Inman
Make Sure you have Quality Data
Don’t Forget “In Game” Data - i.e. Reaction Times
Caution...Intentions...Control...•“The philosophy of this new approach is principally concerned with machine perception of users’ affective reactions.
•Assumption that users respond to content and events occurring during human–computer interaction, and that the machine detects these responses and adapts its behaviour accordingly.
•This may be making the mistake of assuming the machine is in charge.
•It can be argued that this is not how emotion operates in the real world. In human– human interaction, affect has an intentional communicative function.”
(Ward & Marsden, 2004)
Historical - Kunstphysiologie
Physiological Aesthetics
By the 1870s the new field of ‘physiological aesthetics’ burgeoned in pockets across Europe and North America, aiming, to ‘elucidate physiologically the nature of our Aesthetic Feelings’ and ‘to exhibit the purely physical origin of the sense of beauty, and its relativity to our nervous organization’.
For many physiologists, the new evolutionary accounts of sensory functions suggested fresh possibilities for education of artists and artisans.
(Allen, 1877)
Physiologically Informed Art
Used Aesthetic Protractor - “pleasurable angular distances”
Science Fiction?
21st Century Reality
Techno-Sublime: Post-Aesthetic?
Interactive Media
Observer becomes a Performer
“Engagement can give rise to experiences of immersion in immediate sensation” (Bolt, 2007)
“Critical Distance” (of traditional aesthetics) is lost
Move towards appreciation of the “Immediacy of Sensation”
