  9. 10. ...in UoPortsmouth... <ul><li>funded projects in use of second life as a development environment in HCI teaching and other level 3 units. </li></ul><ul><li>use of second life in engineering projects </li></ul><ul><li>distance learning v face to face classes </li></ul>
  10. 11. simulation in digital forensics <ul><li>investigation of digital devices </li></ul><ul><li>documenting the investigation for use in court </li></ul><ul><li>use of hard drives and disk images for student investigation </li></ul><ul><li>some forms of simulation are quite demanding in terms of resources </li></ul><ul><li>Seizure scenarios can be quite demanding </li></ul><ul><li>(typically used an existing office plus an imported PC) </li></ul>
  11. 12. <ul><li>prepare pc </li></ul><ul><li>prepare media/ images </li></ul><ul><li>appropriate room </li></ul><ul><li>appropriate contextual evidence </li></ul>
  12. 13. virtual world simulation <ul><li>larger range of contexts </li></ul><ul><li>pre-prepared </li></ul><ul><li>does not necessarily require tutor interaction </li></ul><ul><li>can be revisited time and again </li></ul><ul><li>'bots' to provide some limited/ constrained interaction </li></ul>
  13. 14. 3 conditions of simulation <ul><li>real world </li></ul><ul><ul><li>based on an existing office, dressed with appropriate extras </li></ul></ul><ul><li>second life </li></ul><ul><ul><li>holosuite based </li></ul></ul><ul><ul><li>mix of large scenarios difficult to achieve in the real world, and smaller locations </li></ul></ul><ul><li>an alternative virtual world </li></ul><ul><ul><li>self contained 'virtual world' </li></ul></ul>
  14. 15. proposed evaluation <ul><li>how effective is the approach? </li></ul><ul><ul><li>learning outcomes </li></ul></ul><ul><ul><li>distractions </li></ul></ul><ul><li>how expensive is it to develop a scenario in this media? </li></ul><ul><ul><li>time </li></ul></ul><ul><ul><li>cost </li></ul></ul><ul><li>how satisfying is it as a learning experience? </li></ul><ul><ul><li>enjoyable? </li></ul></ul><ul><li>how appropriate is this sort of environment for this topic? </li></ul>
