Objectives1. Observation: Study the nature of distributed creativity

in the natural setting of:

1. Brain storming

2. Design

3. Creative Expression

2. Theory: Build a more comprehensive theory of activity

and sensory involvement during brainstorming

3. Design: Explore impact of changes in environment

design on imagination, creativity and problem solving

Imaginarium Technology

• Binocular eye tracking among groups

• Video cameras coordinated with eye tracking

• Kinects for gesture detection

• Portable ERP caps

• Precise sound localization

• Whiteboard and other surface capture

• Automated Annotation of design session

• Remote interaction with other sites

Analytic Techniques

• Ethnographic coding, activity analysis,

• Datamining for patterns among different capture records

• Machine learning using VATIC and crowd sourcing to classify events defined via activity analysis

• Analyses using theories of distributed, situated and embodied cognition

Collaborators Relevant Research Basis

• Kirsh: NSF on Distributed Creative Cognition– In choreography – being expanded to music

• Makeig, Saygin: ERP (Event Related Potentials) during activity

• Trivedi: Video and Auditory awareness systems.• Viirre: Eye Tracking for wayfinding, medical diagnosis

and therapy• Brown: User analytics of virtual worlds

Observation Set-Up for Distributed Creative Cognition in Choreography - Kirsh

Mandeville Auditorium

Cal-IT2

Oculomotor Measuring Equipment

Video Engineering

• Wide Angle Camera to identify head• High resolution camera slaved to get

face/eye activity• Analysis of video image (visible/IR)

Body and Gaze Tracking

• Tool for Collaboration• Centered around whiteboard, display

table, workbench– Annotation– Command interaction (Kinect)

Medical Evaluation• Monitoring of Movement control

– Fall Risk– Movement control– ADL

• Evaluation of Disease progression– Vestibular– Parkinsons

• Diagnosis?– Cerebrovascular vs. Neurodegenerative

Research Questions

• Are binocular indices sensitive indicators of neural disruption

• What do “natural” eye movements look like?– Combined Eye-Head– Head Free

• Scan paths

Embedded Cognition Theory

• Interaction with physical objects– Mental planning, practice

• Learning theory of tasks
