HMDS FOR AUGMENTED REALITY IN AECO:

FUNDAMENTAL FEATURES FOR DEVICE SELECTION

Abstract

Augmented Reality (AR) experiences through Head Mounted Displays (HMDs) for Architecture, Engineering, Construction and Operations (AECO) are already a reality, although little explored compared to other areas. HMDs present a valuable option for AR, since they offer greater pictorial consistency and sense of presence. Given the frequent updates, any presented list of commecially available HMDs would quickly become obsolete. For this reason, we seek to describe the fundamental characteristics that must be observed for the selection of HMDs in order to meet specific demands of activities within the AECO spectrum. In order to present a categorization, the technical specifications of the HMDs were segmented according to: portability, visualization, tracking and positioning systems, resistance to weather and aggressive environments, interaction mechanisms, hardware and software. These characteristics were based on bibliographic references and then correlated with activities commonly developed in the industry. This research contributes to the conscious and careful choice of HMDs, favoring the incorporation of AR experiences in AECO activities.
