Analytics & Analysis
• Where will computation, logic & math fail?
• Relevance, validity, reliability of data uncertain
• Assumptions of the model may not hold in given situation
• Multiple models to chose from
• Previously unknown pattern in data (data discovery)
• “Visually enabled reasoning”* can address this
• Used with mathematical or computational analytics
• Bridge HII to alternative (modal, hybrid) logics
• Emphasize discovery, mixed-initiative human/IS analysis

Visual Analytics
“The science of analytical reasoning facilitated
by interactive visual interfaces”
Tools support understanding implications of data
§ Synthesize information & derive insight from massive, dynamic,
ambiguous, & conflicting data
§ Detect the expected & discover the unexpected
§ Build timely, defensible, & understandable assessments
§ Communicate assessments effectively for action.
“The beginning of knowledge is the discovery of
something we do not understand.”
~Frank Herbert (1920 - 1986)

Visual Analytics Trajectory
(my view)
• Increased multidisciplinarity (not just VAST!)
• Events at Cogsci, HICSS, eSocial Science
• 3/6 Canadian NSERC Strategic Partnership themes (5yr)
• Bridge to data sciences, machine learning
• NSF FODAVA
• EU 7th Framework VisMaster Coordination Action
• DFG Scalable VA Strategic
• More lab-to-”clinic” translational research
• Adapting to science-integrated tech design & evaluation
• Science to build analytics-- the process
• Lab methods are adapting to address research
questions from field work

My Translational Research
• Emergency Management (NSERC, DHS)
• Mobile analytics / sensor analytics
• “Virtual EOC” visual analytic environment
• Aircraft Safety, Reliability (Boeing/MITACS)
• “Pair analytics” of complex quant and text data
• Economics and finance (MITACS, NSF)
• Behavioural economics (portfolios)
• Healthcare Monitoring & Management (CIHR)
• Complex data in health research (CFRI)
• Public health monitoring & management (BC Injury

Understand cognition supported by
interactive visualization
• Visual expertise - how to assess,
Cognitive,
Perceptual
Sciences
model, teach, & build for it
• Individual differences, quantitative
predictions
• Visuomotor expertise - assess,
model, teach, & build for it
• Multimodality & modularity
(cognitive architecture)
Air traffic control research
• Free Flight ATC
“fishtank” projection
• Change camera
position for better
view
• How will global
motion affect
tracking?

& Enns, J. (2005) Multiple Object Tracking Is Based On Scene, Not
Retinal, Coordinates. Journal of Experimental Psychology: Human
Perception and Performance. 31(2), Apr 2005, 235-247.
Conclusion: Humans track in
allocentric space
• Retinal speed of targets does not
determine performance
• Motion of targets relative to each other
does
• But only if motion preserves good metric
characteristics of space
• Explanation is at the level of a human display cognitive system

Understand technological
distribution of cognition
• Build on social science (GT, JAT)
Social
Sciences
approaches to understand
organizations and cognitive work
practices.
• The innovation here is in the
extension of social science to
bridge to the perceptual and
cognitive science theories that
apply to the use of visualization in
analytical tasks.
Distributed Cognition
• “Pair analytics” sessions
• Student visual analyst & trained domain expert
•
collaborate on analytic task
• Student “drives”, expert “navigates”
Analysis of session based on knowledge of human
cognition & communication
• Analysis bridges socsci & cognitive science (Joint
Activity Theory & Grounded Theory)
• Investigating VA tech to support this (Boeing)

In Memoriam: Andrew Wade, MSc.
Visweek 2010 Discovery Exhibi4on
Student Entry Award
Improving Airplane Safety: Tableau and Bird Strikes
Andrew Wade (SFU), Roger Nicholson (Boeing)
Andrew’s 4 month pair analy4cs internship with Boeing Safety Engineer Roger Nicholson made changes to 5 aircra> and the pilot training manual.
Andrew Wade defended his MSc. thesis “ Visual analy4cs for avia4on safety: A collabora4ve approach to sensemaking” in August 2011.
On October 6, 2011 Andrew was killed when his sightseeing flight to Mount Everest crashed in foggy condi4ons. Andrew’s MSc was awarded posthumously in October. It was accepted by his father, Don Wade.
Robust Visual Analytics
• A warrant (ala Toulmin) for process of
policy-making facilitated by interactive
visualization
• Data, its processing and arguments that result
• A visual analytics (not just visual analysis)
• Desiderata (at least) for communication between
analysts and policy-makers
• General principles derive from lab studies and
from multiple real-world cases
D-Cog VA Projects
• VR Design
Environment
(GMR)
• Fishtank VR air
traffic control
(Hughes/
Raytheon)
• Car interfaces
(Nissan)
• Perception of depth
in VR displays
(Fechner)
• Ability to track
targets in moving
spaces (FINST)
• Perception of touch
on the outer leg
• Discourse in “pair
analytics” (JAT)
Probs with current
• Too much solo analyst, too little
communication and collaboration.
•
•
•
Multiple stakeholders, roles, and knowledge
Bridge to organizational & societal systems
Tactics as well as strategy
• Poor integration of modelling and
visualization

How are VA systems
• Development based on understanding of
expert cognition in situ
• Informed by current cognitive & social science
• Engagement with community of experts
• Emergent cognitive science of expert reasoning
• Obvious support for analytical processes-collaboration and interaction as well as
observation
• Graphical analog for analytic processes
• Support “Human-information discourse”
• Integrated across roles in the community
Extending analytics systems
• Coordinated technological, methodological,
organizational & training support
• Many technologies w/o rich visualization-small form factor devices, sensors, data
input.
• Example: VA for Emergency Management
NSERC SPP (+ 2 SPP companion
proposals)
• Population: cell phones
• First responders: blackberries
• Data fusion centres: geotagged sensor networks,
Cognitive Systems Approach
• Cognitive System composed of
human
and computational cognitive processes
• Bound together through high-bandwidth
interface of vision/visualization for humaninformation discourse
• Stream processor, many modular subprocessors
working in parallel, a learning system with large
variation among individuals in methods,
capabilities, and time course of processing
• Scalable visual analysis systems, automatic data
analysis and interactive visualization for customdesigned processes for the exploration and
