EVET Software

EVET was created using the Software Development Kit (SDK) supplied with the computer game Half-Life 2™. The SDK can be used for free to create virtual environments providing this is not done for commercial purposes. This allows virtual environments to be generated on a not-for-profit basis, with the environment and the actions within it to be designed according to the needs of the researcher. We have written data extraction utilities (based in Matlab and Python) that extract and summarise the data produced by the the use of environments created using this SDK.

These utilities are available for free download on the condition that they are not sold or used for any commercial purpose, and on the condition that any reports, publications or other forms of dissemination of the results of their use cite the original sources:
"Logie, R.H., Trawley, S. & Law, A.S. (2011). Multitasking: Multiple, Domain-Specific Cognitive Functions in a Virtual Environment. Memory and Cognition, 39, 1561-1574. DOI 10.3758/s13421-011-0120-1."

Also available for download is software to run a version of the Travelling Salesman Problem, as described in the two publications above. Again, this software is available for free download on the condition that it is not sold or used for any commercial purpose, and on the condition that any reports, publications or other forms of dissemination of the results of its use will cite the original sources listed above.

A description of how EVET was generated and how this experimental approach can be used is available for download here:
