In this issue I wish farewell to Larry Rosenblum, who has decided to step down from our editorial board. He has contributed to CG&A for many years, most signi cantly as the editor of two departments, Visualization Blackboard and Projects in VR. Both have been regular and prominent features of CG&A. Projects in VR covered both applications and theory relevant to virtual reality. Larry is the Pro...

As a consequence of the scarcity studies augmented reality (AR) in Spain, this study developed questionnaire to evaluate teachers’ perceptions on use AR for heritage teaching (n = 347 teachers: n 131 in-service/n 216 in-training). The objectives were to: (1) identify existing knowledge about AR; (2) educational strategies teachers value most apps teaching; (3) necessary functions; (4) determine...

Augmented Reality (AR) is increasingly influential in education. AR technology allows users to learn and practice a simulated environment that enables repetition, correction, failure without risk. The present study evaluated users’ attitudes towards using for learning complex tasks. are asked interact with an Piling (ARP) application shows various steps of construction process. A set selected p...

Recent trends in military operations (quick-reaction forces, putting fewer warfighters at risk, and increasing the use of unmanned vehicles) have increased the difficulty in acquiring and maintaining situation awareness (SA). Augmented reality (AR) has the potential to meet some of these new challenges. AR systems integrate computer-generated graphics (or annotations) with the user’s view of th...

Despite evidence that the majority of knowledge management (KM) initiatives miscarry, there has been a paucity of critical, in-depth research into the causes of failure. In this paper, an action research (AR) project is described in a major motor manufacturer (WWM) focusing on one of their key knowledge processes (Design for Manufacturabilty, DFM). Intensive field work using a grounded theory m...

This study presents an approach wherein photographs with a high degree of overlap are clicked using a digital camera and used to generate three-dimensional (3D) point clouds via feature point extraction and matching. To reconstruct a building model, an unmanned aerial vehicle (UAV) is used to click photographs from vertical shooting angles above the building. Multiview images are taken from the...

Data envelopment analysis (DEA) is a methodology for evaluating the relative efficiencies of peer decision-making units (DMUs), in a multiple input/output setting. Although it is generally assumed that all outputs are impacted by all inputs, there are many situations where this may not be the case. This article extends the conventional DEA methodology to allow for the measurement of technical e...

Current libraries use an assortment of uncoordinated and unreliable techniques for storing and managing their digital information. Digital information can be lost for a variety of reasons: magnetic decay, format and device obsolescence, human or system error, among many others. In this thesis, we address the problem of how to build archival repositories (AR). An AR has the following combined ke...
