Indoor positioning systems (IPS) for augmented reality: an analysis of accuracy

The technology augmented reality (AR) enables to enrich the real world with information from the virtual world, through a technological device that runs applications in real time. However, RA technology, despite being used in different sectors, it still has limitations that prevent it from being entered into the industrial field more effectively and comprehensively. Barriers that lead to it include limitations related to user interaction, hardware devices (which need to be more comfortable), and recognition and tracking techniques. The aim of this study is to evaluate the imprecision generated by indoor positioning systems in the measurement of virtual coordinates for future RA application in the industrial context. For this, a review of the existing indoor positioning systems (IPS's) was carried out and only those that met the precision premise of this research were selected. The results demonstrated that the technologies based on images and ultrasonic, represented by the devices Hololens and Marvelmind respectively, presented results within the expected range in this work.
