Evaluating Multiuser Augmented Reality For 4D Construction Plan Review

Abstract: Construction plan review meetings benefit from visualizing 4D construction models using various media such as Immersive Technologies (ImT). However, ImT, such as Augmented Reality (AR), have not been thoroughly investigated for their effects on collaborative reviews. This paper aims to evaluate the effect of using a developed 4D Multiuser AR (4DMAR) application on task performance using a comparative study against a screen-based environment. A questionnaire and observational data were used to measure the participants’ experience and preferences. Sixty-two students found the interaction in both environments easy but perceived 4DMAR as more interactive and suitable for collaborative plan reviews.
