Extended reality – How to boost quality of experience and interoperability

3. DESIGN AND TEST METHODOLOGY

3.1 Test setup
In this research, two developed mobile applications based on
ARCore and ARKit are used to determine the accuracy and
reliability of augmented reality solutions. Six mobile devices
were utilized, which are Samsung S8, S10, S20, A20 and
A32 and an Apple iPad Pro 5th generation. The Apple iPad
Pro 5th generation represents ARKit while the other devices
represent ARCore. The reason for only having one device to
represent ARKit is due to the fact that the chosen device is
the latest to house a LiDAR scanner and has the best
configurations for dynamic ranging which all the other
ARCore devices do not possess. The applications were both
developed on Unity engine using the ARCore and ARKit XR
Plugins versions 4.2.3. The backend code was done using
visual studio; a desktop computer was utilized to develop
both applications, and finally a tape measure was used to act
as a control for the entire experiment. The entire test
application layouts are presented in figures 4 and 5. Table 1
outlines the key camera configurations for each device used
in this study. Figure 5 – ARKit application layout
