Educational uses of virtual reality technology by Christine Youngblut( Book )

3 editions published in 1998 in English and held by 6 WorldCat member libraries worldwide

The potential of VR technology tor supporting education is widely recognized. It has already seen practical use in an estimated 20 or more public schools and colleges, and many more have been involved in evaluation or research efforts. This document reviews current efforts that are developing, evaluating, or using VR technology in education. It builds a picture of the states of the art and practice, and reviews some of the critical questions that are being addressed. Educational uses of the technology are broadly distinguished as those where students interact with pre-developed VR applications and those where students develop their own virtual worlds in the course of researching, understanding, and demonstrating their grasp of some subject matter. Forty-three efforts in the category of pre-developed applications and another 21 efforts in the category of student virtual world development are reported in this paper. The results of 35 evaluations that have been completed on these efforts are summarized. Another 20 ongoing or planned evaluations are identified
A Strategic Defense Initiative Organization Software Testing Initiative( Book )

1 edition published in 1990 in English and held by 1 WorldCat member library worldwide

This paper provides a top-level description of an initiative designed to develop critically needed software testing capabilities prior to a Strategic Defense System (SDS) Milestone II decision. It identifies several SDI software testing requirements and examines the state of the art and practice in this field. Deficiencies were found between needed Strategic Defense System (SDS) capabilities and the expected available technology. Aspects of SDS software testing that should be addressed are described, including the ability to assure the correctness of SDS software, the types of software to be tested, and the ability to perform required testing within cost and schedule constraints. The document contains several detailed example project descriptions, and provides a brief overview of the software testing technology horizon

A Verification, Validation, and Certification Plan for the Strategic Defense Initiative Organization Level Two System Simulator( Book )

1 edition published in 1990 in English and held by 1 WorldCat member library worldwide

The Level Two System Simulator (L2SS) is a tool being developed for the Strategic Defense Initiative (SDI). The L2SS will be used to experiment with and validate design concepts for elements of the Phase 1 Strategic Defense System (SDS) architecture and ensure that the various elements can meet the requirements of an integrated Phase 1 SDS system. The L2SS is one of a series of planned SDS simulators, each providing additional SDS Phase 1 analysis capabilities. This paper describes practices that can promote the application of advanced software test and evaluation (T & E) tools, techniques, and methods for the L2SS. The paper examines the verification, validation, and certification (VV & C) processes and products that could be used to assist in building and demonstrating confidence in the L2SS. The primary method used to derive these practices and processes was an analysis of literature discussing commonly accepted VV & C principles. In addition, the study benefited from discussions with members of the L2SS software development community. The paper is intended to describe software test and evaluation requirements and guidelines that will be reflected in the L2SS Software Development Plan, and to provide a vehicle for documenting information related to the Test and Evaluation Master Plan

What a Decade of Experiments Reveals about Factors that Influence the Sense of Presence( )

1 edition published in 2006 in English and held by 0 WorldCat member libraries worldwide

The sense of presence, "being there," is a real phenomenon. The literature contains many anecdotal accounts of how users have reacted to a virtual scene in instinctual ways that suggest they believe, at least for a short time, that virtual events are real. Yet, much remains unknown. Does a strong sense of presence cause users to engage mental models and cognitive processes that they have already developed in a real environment? Will behavior learned in a virtual-world transfer to a corresponding real scenario? This document reviews what experimental results reveal about technical factors and task characteristics that may influence the sense of presence. For the discussions here, "presence" is loosely defined as the subjective experience of being in a place or environment, even when one is physically situated in another place or environment. "Co-presence," then, is the experience of being with another person (actual or computer generated) in a place or environment such that he has access to that person and, conversely, that person has access to him. This is different from "social presence," which goes a step further to address social psychological ideas of personal interaction and implies some awareness of a collocated person's intelligence and intentions. Factors that may be related to co-presence and social presence have been examined less than those that may influence presence. This report reviews the results of experiments that have examined the sense of presence experienced in virtual environments. The report provides guidance about factors that have a good probability of manipulating presence, gives a feel for the scope of experimentation that has been performed, and facilitates the identification of critical gaps where future research may make the most difference. Over 170 experiments are identified, but the analysis focuses on those experiments that have been replicated (more or less) and on factors that have shown consistent results across studies
Climate Change: Issues in the Science and Its Use( )

1 edition published in 2009 in English and held by 0 WorldCat member libraries worldwide

The U.S. is on the threshold of major changes in how it conducts climate change science research. These changes are being driven by several imperatives. One driving force is the growing recognition of the role that societal and ecological processes play in climate change. Another is the need to better support stakeholders who require climate-related information for the development of mitigation policy and adaptation activities. Wide expectations that the new administration will give new impetus to U.S. climate change research, along with increased Congressional interest also play a role. Finally, a new consensus that climate change is progressing much more rapidly than projected just two years ago adds a sense of urgency to these topics. This paper presents a high level picture of this state of events and the key issues that have arisen. It is one in a series of papers looking at climate change issues. The purpose of this series of papers is to raise awareness of the full scope of climate-related concerns. By identifying the key issues, each paper identifies potential opportunities for strengthening the U.S. response to climate change

An Examination of Selected Software Testing Tools: 1992( )

1 edition published in 1992 in English and held by 0 WorldCat member libraries worldwide

This paper reports on the examination of 27 tools that provide for test management, problem reporting, and static and dynamic analysis of Ada code. It provides software development managers with information that will help them gain an understanding of the current capabilities of tools that are commercially available, the functionality of these tools, and how they can aid the development and support of Ada software. During the course of the examination, the static and dynamic analysis tools were applied to a sample Ada program in order to assess their functionality. The test management and problem reporting tools were also subject to a practical examination using vendor-supplied data. Each tool was then described in terms of its functionality, ease of use, and documentation and support. Problems encountered during the examination and other pertinent observations were also recorded. Available testing tools offer important opportunities for increasing software quality and reducing development and support costs. The wide variety of functionality provided by tools in the same category, however, and, in some cases, lack of tool maturity, require careful tool selection on behalf of a potential user
A Survey of Computer Programming Languages Currently Used in the Department of Defense( )

1 edition published in 1995 in English and held by 0 WorldCat member libraries worldwide

This study reports on a programming language survey commissioned by the Assistant Secretary of Defense for C3I to determine how many programming languages are being used in the DoD today as compared to 20 years ago when the DoD began development of the Ada language. The sample population for this survey consisted of weapons systems taken from the 1994 Presidential Budget requests for RDT & E programs exceeding $15 million and Procurement budgets exceeding $25 million. The current DoD list of major Automated Information Systems was used as the survey sample for non-weapons systems. The survey found that over 80% of the applications in the sample were written in third generation languages. Moreover, it identified 37 third generation languages in contrast to an estimate of at least 450 general purpose languages and dialects in 1974. In weapons systems modernization, Ada is the most commonly used language

Government-Sponsored Research and Development Efforts in the Area of Intelligent Tutoring Systems. Summary Report( )

1 edition published in 1995 in English and held by 0 WorldCat member libraries worldwide

Individualized tutoring has long been recognized as offering a two-standard deviation improvement in student achievement over what is achieved by traditional classroom teaching methods (Bloom 1984). ITS are intended to make the advantages of individualized tutoring widely available through the use of modern computer technology. Essentially, an ITS is a computer-aided system that acts like a personal tutor in presenting instruction and remediation in a manner tailored to each individual, based on a gradual accumulation of knowledge about that individual. The majority of early computer-aided instruction systems were either tutorial or drill-and-practice systems. In both these forms of computer-aided instruction, the student is led through the material to be taught, providing a response at every step. Based on these responses, the student is moved ahead to the next part of the material, or else the current part is reviewed until subsequent responses indicate correct understanding. The actions taken by the system to student responses are mostly preprogrammed. Researchers began investigating how to tailor instructional actions to individual students and this led to the type of computer-aided instruction systems called intelligent tutoring systems.

The report recommends actions that may allow potential benefits of emerging RFID technology to streamline DLA operations
Experience of Presence in Virtual Environments( )

1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide

Much attention has been focused on feeling a sense of presence in a virtual environment (VE). The potential importance of presence is based on an assumption that increasing the sense of presence experienced in a VE leads to an improvement in task performance. This document summarizes the results of experimental work that has been performed. Nearly 70 different measures of presence are identified, and over 100 studies that investigated various issues about the presence construct are cited. There are 83 findings regarding a relationship between presence and task performance. Roughly half of these show a significant correlation most in the expected direction. As yet, there is no evidence whether the relationships that do exist are causal in nature. Nonetheless, some conclusions are clear. Despite a decade of research, the role of presence in VEs is still unclear. No commonly agreed theory of presence much less common measures for this construct exist. Some evidence exists that particular technological, task, and personal characteristics can influence the extent of presence experienced in a VE. However, the critical question of whether manipulating presence can achieve improved task performance remains unanswered
