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”
