Measured Precision for Augmented Reality Devices used in Construction

Augmented reality experiences for construction can be facilitated through different hardware and software platforms. Having researched in this area for some time we have fielded many questions regarding the quantitative precision of these devices. This research sought to provide some preliminary answers to questions related to the quantitative precision of the augmented reality experiences.

Currently, most of the AR activities in the construction industry are performed using headsets like the Microsoft’s HoloLens and on mobile devices such as Apple’s iPhone and iPad.

Researchers set up an experiment at the field lab where building science students were tasked with installing plumbing penetrations. The mock plumbing penetrations were mounted on prism poles and the students were instructed to place the penetrations where they visualized them in the hologram. Each student team installed three plumbing penetrations and after they were installed their location was recorded with a total station.

Student teams performed the same exercise with one of three augmented reality devices (Hololens, iPhone, iPad). Each of these devices was running on the same software platform Trimble Connect. Of the devices used the Hololens and the iPad performed the best in facilitating the correct placement of the plumbing penetrations.
