On this episode of the Built Revolution podcast, we spoke to the members of the Construction Industry Institute (CII) Virtual Reality in Construction Research Team. The team conducted Immersive Virtual Reality (IVR) user tests on design review and planning tasks, observing both novice and expert participants. The researchers measured and analyzed several indicators of user performance of a control and test groups that included detecting design errors, judging the scope of work, assigning an installation sequence for each installation work package, and remembering the scope of work. The test results clearly demonstrated that IVR enhanced the users' ability to perform the review tasks. Participants in the IVR (treatment) group scored 21.86% to 142.92% higher than the desktop (control) group.
