simulation and role play in df• creation of a 'safe' environment in which skills

can be practised• e.g. flight simulation• link simulator• MS flight simulator

virtual reality

• jaron lanier “virtual reality” 1987• morton heilig's sensorama 1962• nasa• medical training (e.g. ExPERT Centre

simulation, high fidelity v lo fidelity)

virtual worlds• a representation of a virtual environment

– initially text description– later using 3D graphics– may include machine generated characters– multiple 'locations'

• multi user– network interaction between real users through the

environment– MUD (multi user dungeon)

• persistent– 24/7 environment– MMORG (massively multiuser online role playing game)



second life

• world of warcraft (11m users)– 1994– hacking and slashing (but also team working)

• second life (linden labs)– 2003– “...a world created by its own netizens...”– (follows the C21st of user contributed content)– adult v teen areas– 'goal-less'





second life in UK HE– Computer games: Loughborough University,

University of Teeside, Bromley College– Project Management: University of Bedfordshire– Health Informatics: University of Plymouth– 3D design: University of Sunderland, University of

Hertfordshire, University of Strathclyde– General topics in Computer Science: University of

Greenwich, Heriot-Watt University, The Open University.

– Theatre Design: Coventry University– Health, medical and bioscience applications:

Glasgow Caledonian University, Nottingham Trent, University of Worcester, University of Sunderland

(Virtual Worlds Watch snapshot for 2009)



...in UoPortsmouth...

• funded projects in use of second life as a development environment in HCI teaching and other level 3 units.

• use of second life in engineering projects

• distance learning v face to face classes



simulation in digital forensics• investigation of digital devices• documenting the investigation for use

in court• use of hard drives and disk images for

student investigation• some forms of simulation are quite

demanding in terms of resources• Seizure scenarios can be quite

demanding• (typically used an existing office plus

an imported PC)



• prepare pc• prepare media/ images• appropriate room• appropriate contextual evidence



virtual world simulation

• larger range of contexts• pre-prepared• does not necessarily require tutor

interaction• can be revisited time and again• 'bots' to provide some limited/

constrained interaction



3 conditions of simulation

• real world– based on an existing office, dressed with

appropriate extras

• second life– holosuite based– mix of large scenarios difficult to achieve in

the real world, and smaller locations

• an alternative virtual world– self contained 'virtual world'



proposed evaluation how effective is the approach?

learning outcomes

distractions how expensive is it to develop a

scenario in this media? time cost

how satisfying is it as a learning experience?

enjoyable? how appropriate is this sort of

environment for this topic?
