The training, Investigator Virtual Reality (IVR), is available only to law enforcement agencies. IVR was developed by the Law Enforcement Innovation Center (LEIC) at the University of Tennessee in Oak Ridge. The Center modified its 10-week in-residence training into an online version in order to provide training for agencies with limited budgets and resources. The online lessons cover topics such as oblique lighting, evidence marking, evidence recording with a digital camera, evidence sketching and diagramming, and scene evaluation. The LEIC is currently working to make the online training eligible for 20 hours of POST (Peace Officer Standards and Training) Certification.
