| Abstract | |
Augmented Reality (AR) is a technology that complements the real-world view through overlays of virtual elements, generating a composite view (real environment with the addition of virtual models) in real time. Although AR technologies have been developed and successfully implemented in a number of engineering fields (e.g. automotive industry), it has only been superficially applied in Architecture. This research has explored the use of AR by potential users to discriminate the conditions that could ensure that this technology could be used in architectural Participatory Design (PD) during the conception stage. The general objective was to verify de use of AR applied in PD in the process of conception of the architectural design. The hypothesis was that both designers and non-specialists could use the AR as a support tool for viewing and communication during a PD workshop. In order to contextualize the research and allow experimentation, the evaluations were applied to the design of a leisure area in Social Housing. This was an applied research, with an investigative character, and its basic scientific method was the Design Science Research. This research was consisted of six stages: understanding; suggestions; development; evaluation, conclusion and communication. In the Understanding stage, the problem to be solved and its limits were defined and formalized, providing the theoretical basis, addressing issues related to the state of the art of the AR technology and the PD applied to architecture. In the Suggestions stage the aim was to look for an AR tool that could be used in the proposed context, assessing the operation of various systems and display devices. It was evident the need for developing a specific application that could support a PD workshop. Therefore, in Development stage, there was the development of the AR application called equipAR!. At this stage, a pilot test of the system usage also took place. It was found that there was the need to evaluate which conditions favored the recognition of 3D models in AR. Thus, in the Evaluation stage, user evaluations were conducted making use of subjective measures and qualitative analyzes. Three user evaluations were performed: (i) 3D model recognition as a function of the scale and the type of marker used; (ii) multiple 3D models recognition, with or without an auxiliary projection; (iii) handling of multiple models in a participatory process. The results obtained in the evaluations (i) and (ii) were used to improve the application equipAR! and also, to develop guidelines for the AR use in a PD. A PD workshop was performed in the evaluation (iii). In the Conclusion stage, the results obtained and the research contributions in relation to the artifact developed and its application in the PD practice were discussed. This research main contributions are: (i) an artifact in the form of an AR application, equipAR!, which uses specific 3D models of urban equipment for leisure areas; (II) the processing steps for developing 3D models suitable for use in AR applications that makes use of Metaio¿s SDK; iii) a PD workshop method using AR that was conceived, experimented and evaluated; (iv) guidelines for using AR in a PD in order to facilitate the communication between designers and non-specialists during the conception phase of the architectural design (AU) | |
