Universal Virtual Laboratory (UVL)

提案# hrd -0004292机构：天普大学首席研究员：Bruce butz标题：“通用虚拟实验室”摘要通用虚拟实验室（UVL）项目的重点是寻找新的方法来容纳严重运动障碍的人到电气工程实验室。任何失聪或听力障碍的参与者也将得到照顾。该项目的主要目标是：1)建立一个模拟但真实的实验室，使学生能够命名，放置和互连各种电路元件，电子设备，电气系统，信号发生器和测量仪器。2)使用户能够通过鼠标或指针的直接操作，或通过开关、键盘或语音识别的离散操作来操作虚拟仪器、元件和设备。该系统将通过使用基于规则的算法，最大限度地提高学生与系统交互的速度。3)开发新颖的输入/输出设备，以适应各种残疾学生。4)允许学生以任何物理可行的方式连接典型实验室储藏室中可用的元件和仪器，并获得在实验室中可能经历的相同响应，包括故障。5)通过与软件应用程序包的无缝集成，模拟相互连接的元素和对象的性能。这些封装将产生表示电流、电压、频率、功率等的数据流。数据流将被用作各种模拟测量仪器的输入。6)为学生提供一个智能实验室助理，以模拟专家实验室助理的角色，回答学生的问题，专家实验室助理在主题和残疾住宿方面都是专家。7)将生成的UVL模块放在CD rom上，并使这些模块在万维网上完全发挥作用。8)在万维网上、在适当的期刊上以及通过在著名会议上的演讲来传播结果。本计画所建立的架构，可作为其他工程课程及物理科学课程设计及实境虚拟实验室的模板。

Proposal # HRD-0004292Institution: Temple UniversityPrincipal Investigator: Bruce ButzTitle: "Universal Virtual Laboratory"ABSTRACTThe focus of the Universal Virtual Laboratory (UVL) project is finding new ways to accommodate people with severe motor impairments to an electrical engineering laboratory. Any participants who are deaf or hard-of-hearing will also be accommodated. The major goals of the project are to:1) Develop a simulated, but realistic, laboratory that will enable students to name, place and interconnect various circuit elements, electronic devices, electrical systems, signal generators and measuring instruments. 2) Enable users to manipulate virtual instruments, elements and devices either by direct manipulation, with a mouse or a headpointer, or by discrete actions with switches, keyboard, or speech recognition. The system will maximize the speed with which the student can interact with the system by using rule-based algorithms. 3) Develop novel input/output devices that will accommodate various disabled students.4) Permit the student to connect in any physically feasible way the elements, instruments available in a typical laboratory storeroom, and obtain the same responses, including failures, that would be experienced in the laboratory.5) Simulate the performance of the interconnected elements and objects by integrating them seamlessly with software application packages. These packages will produce a data stream representing current, voltages, frequencies, power, etc. The data stream will be used as inputs to the various simulated measuring instruments.6) Provide the student with an intelligent laboratory assistant that will answer the student's questions in a way that simulates the role of an expert laboratory assistant who is expert in both the subject matter and accommodation of disabilities.7) Place the resultant UVL modules on CD ROMS and make these modules completely functional on the World Wide Web.8) Disseminate the results over the World Wide Web, in appropriate journals and through presentation at notable conferences. The framework developed in this project could be used as a template for the design and implementation of realistic virtual laboratories in other engineering courses as well as in the physical sciences.
