    In any mega construction project, quality survey managers play a vital role in judging quality of work done by different contractors and sub-contractors. Usually a quality survey manager uses a hard copy form to records the survey information and for reporting to the client. Typically, this entire process takes a week’s time or even more, there is no workflow in place for recording information and analyzing trends in irregularity by the quality managers. The requirement to capture and report quality survey observations in real time evoked a need to research on mechanism for recording the observations using smart phone and existing GIS infrastructure without any development on smart phone and mobile devices. An integrated solution using an editable ArcGIS Server feature service and ArcGIS online web maps was developed in order to perform the quality survey. The paper describes the mobile GIS solution for construction projects. The solution allows recording observations in a real time environment through a user-friendly interface and workflow driven process. It also allows users to capture the picture and attach it to an editable feature service. The client can view this information in real time using ArcGIS online or in the enterprise geodatabase. The use of the Esri online ensures restrictions on accessibility of the content and takes advantage over other application because no programming or development is required. In addition, the information is stored in Oracle database and used for analysis in future, based on the changing reporting requirements. The developed solution saved on time, money and is easy to use and deploy

    Paper brochure is one of the typical approaches that have been used by most higher learning institutions (HLIs) to disseminate information to their prospective students.However, some drawbacks of paper brochure include information consisting of only text and picture that is static non-interactive and if updated, the brochure will be obsolete.With the advent of mobile technology, new technologies including Mobile Augmented Reality (MAR) have been introduced to facilitate human life.This paper discusses the design and evaluation of an MAR based interactive brochure (ibrochure) for promoting the Universiti Utara Malaysia (UUM) amongst the international students. User evaluation was conducted amongst the international students and the results indicated that the respondents highly agreed on all the measures that include; Usefulness, Ease of Use, Effects on Motivation, Out-come/Future Use, and Satisfaction of the i-brochure.The introduction of the i brochure coincides with the needs of the students to acquire comprehensive information about UUM

    Augmented and virtual reality in construction: Drivers and limitations for industry adoption

    Get PDF
    Augmented and virtual reality have the potential to provide a step-change in productivity in the construction sector; however, the level of adoption is very low. This paper presents a systematic study of the factors that limit and drive adoption in a construction sector-specific context. A mixed research method was employed, combining qualitative and quantitative data collection and analysis. Eight focus groups with 54 experts and an online questionnaire were conducted. Forty-two limiting and driving factors were identified and ranked. Principal component analysis was conducted to group the identified factors into a smaller number of factors based on correlations. Four types of limiting factors and four types of driving factors were identified. The main limitation of adoption is that AR and VR technologies are regarded as expensive and immature technologies that are not suitable for engineering and construction. The main drivers are that AR and VR enable improvements in project delivery and provision of new and better services. This study provides valuable insights to stakeholders to devise actions that mitigate the limiting factors and that boost the driving factors. This is one of the first systematic studies to present a detailed analysis of the factors that limit and drive adoption of AR and VR in the construction industry. The main contribution of this study is that it grouped and characterized myriad limiting and driving factors into easily understandable categories, so that the limiting factors can be effectively mitigated and the driving factors potentiated. A roadmap with specific short-term and medium-term actions for improving adoption was outlined

    PRE-SERVICE TEACHER TRAINING EXPERIENCES VIEWED AS A CULTURAL ACTIVITY

    What are the experiences of career-changing pre-service middle school teachers undergoing a group-based activity as part of their training? This series of studies explored two aspects of answering this question. In the first manuscript, a methodology of a novel virtual phenomenology interview technique attempts to determine the influence of a virtual world interviewer compared to a traditional face-to-face setting. While syntactical and other significant differences were found, there was no significant difference found comparing meaning units derived from both settings. In the second manuscript, these meaning units were analyzed to create an essence of the experience for the study\u27s participants, using a modified version of Moustakas\u27 (1994) phenomenology technique viewed through the lens of Cultural Historical Activity Theory (Engeström, 1987). The transcripts of participants were analyzed using this phenomenological technique yielded five meaning themes: Teamwork Function, Grade Orientation, Assignment Structure Conflict, Theory versus Practice Divergence, and Tool for Future Practice. Tensions within the elements of the activity system were identified from the interview transcripts and examined. These findings were used to create a composite textural description, a composite structural description, explained using a graphic depiction of knotworking (Engeström, 1999), and a narrative essence of the experience. A conclusion of both studies, noting a summary of the findings, implications for teacher education, limitations of the studies, and recommendations for future research is also presented

    Panoramic Augmented Reality for Persistence of Information in Counterinsurgency Environments (PARPICE)

    Modern Counter-Insurgency (COIN) and Irregular Warfare (IW) are increasingly complex. Contributing to this complexity is the need to develop and maintain a mental map of relevant environmental and historical factors and their interactions, generated from disparate sources of information that must be organized, processed and integrated. Compounding this challenge is the fact that mental pictures cannot easily be passed from one soldier to the next. This is a problem when the tactical situation dictates frequent changes in unit Areas of Operations (AOs), and particularly in cases where units rotate on a regular basis. When units hand over an AO, the incoming unit must quickly rebuild a mental picture and narrative of its operating environment. Because of this, historical organizational knowledge is lost that could otherwise increase combat effectiveness and reduce casualties. This thesis discusses a prototype architecture for a system that will enable a vehicle crew commander to spatially input, organize and view fused tactical information through placement of 3D interactive symbols directly into the real-life on-site scene from the vehicle perspective. A panoramic camera, dashboard monitor and head tracker give the commander a complete view of the vehicle surroundings for improved situational awareness, and a 360-degree LiDAR scanner supplies depth information for accurate annotation geo-location. This system is intended to generate greater situational understanding of the complex environment present in COIN operations, in order to allow greater performance and survivability of the vehicle crew. Such a system, if fielded, can create the ability to add numerous other capabilities to the combat vehicle crew.http://archive.org/details/panoramicaugment109455057JIEDDO; HQDA G-8 CAAUS Army (USA) authorApproved for public release; distribution is unlimited
