“…Previous studies have discussed the use of 3D visualization in general [25], and specifically AR, for the visualization of architectural design to adapt designs to the environment, avoiding problems of scaling, lighting, and texturing [26][27][28][29]. In addition, through these technologies, a user outside of the professional sector can obtain more enjoyable access to all types of information, such as tourist applications [30].…”

The final publication is available at link.springer.comA mixed-methods study evaluating the motivation and satisfaction of Architecture degree students using interactive visualization methods is presented in this paper. New technology implementations in the teaching field have been largely extended to all types of levels and educational frameworks. However, these innovations require approval validation and evaluation by the final users, the students. In this paper, the advantages and disadvantages of applying mixed evaluation technology are discussed in a case study of the use of interactive and collaborative tools for the visualization of 3D architectonical models. The main objective was to evaluate Architecture and Building Science students’ the motivation to use and satisfaction with this type of technology and to obtain adequate feedback that allows for the optimization of this type of experiment in future iterations.Postprint (author’s final draft

“…The advantages of using augmented reality system on Architectural, Engineering, Construction (AEC) application has been extensively studied by many researchers (e.g., Behzadan and Kamat 2007;Behzadan et al 2008;Chi et al 2013;Dunston et al 2003;Golparvar-Fard 2009a, 2009bHammad et al 2009;Hou and Wang 2010;Kuula et al 2012;Schall et al 2009;Wang 2008;Wang and Dunston 2006;Woodward et al 2010;Yeh et al 2012). They have shown that augmented reality indeed improve physical task performance and can reduce mental workload of engineers for AEC tasks (Wang and Dunston 2006).…”

High-precision vision-based mobile augmented reality system for context-aware architectural, engineering, construction and facility management (AEC/FM) applications

Background: Many context-aware techniques have been proposed to deliver cyber-information, such as project specifications or drawings, to on-site users by intelligently interpreting their environment. However, these techniques primarily rely on RF-based location tracking technologies (e.g., GPS or WLAN), which typically do not provide sufficient precision in congested construction sites or require additional hardware and custom mobile devices. Method: This paper presents a new vision-based mobile augmented reality system that allows field personnel to query and access 3D cyber-information on-site by using photographs taken from standard mobile devices. The system does not require any location tracking modules, external hardware attachments, and/or optical fiducial markers for localizing a user's position. Rather, the user's location and orientation are purely derived by comparing images from the user's mobile device to a 3D point cloud model generated from a set of pre-collected site photographs. Results:The experimental results show that 1) the underlying 3D reconstruction module of the system generates complete 3D point cloud models of target scene, and is up to 35 times faster than other state-of-the-art Structure-from-Motion (SfM) algorithms, 2) the localization time takes at most few seconds in actual construction site. Conclusion:The localization speed and empirical accuracy of the system provides the ability to use the system on real-world construction sites. Using an actual construction case study, the perceived benefits and limitations of the proposed method for on-site context-aware applications are discussed in detail.

“…[14] As AR-based simulations often create environments that go well beyond one's field of vision, we should also include input that are not explicitly given through motions performed by the user's arms or fingers, but instead by the position of their body. Particularly, we can collect information about the user's location through some type of positioning system such as the Department of Defense's Global Positioning System [22]. We can also utilize different sources of information to gain a more in-depth perspective of the user's location as well as orientation by adding to the GPS coordinates also information retrieved through a compass, which will help the system track what the user is seeing [24] .…”

“…The majority of video see-through technologies have the ability of projecting the images directly on touchscreens, which allow for the use of technologies such as styluses [21]. Of course, depending on the type of application, we can also resort to standard joysticks [22] or special manipulators realized ad-hoc for the system [23]. …”

Abstract-Augmented Reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input and output including sound, graphics or haptic input and feedback mechanisms. It has been reported that the use of AR for educational purposes provided opportunities for reflection, capabilities for multiple representations, and co-design of personalized learning experiences which contribute to promote active learning. However, most of the reported applications are for students at the elementary or high school level. There are no reported formal studies on AR application on a college/university level. Based on this lack of information, several questions arise: Are the benefits unique to the elementary and high school students? If AR is used in college classrooms, will it show similar benefits? This paper proposes an Augmented Reality in Computing Education (ARICE) framework for using an AR educational system in undergraduate computing education to improve student performance, retention and learning outcomes. A research plan on how to evaluate the framework has also been presented.
