Universal Virtual Laboratory (UVL)

提案#HRD-0004292机构：天普大学首席研究员：Bruce ButzTitle：“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，将严重运动障碍的人安置到电气工程实验室。任何失聪或听力障碍的参与者也将被接纳。该项目的主要目标是：1)开发一个模拟的、但现实的实验室，使学生能够命名、放置和互连各种电路元件、电子器件、电气系统、信号发生器和测量仪器。2)使用户能够通过直接操作、使用鼠标或头指针，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来最大限度地提高学生与系统交互的速度。3)开发新的输入/输出设备，以适应各种残疾学生。4)允许学生以任何物理上可行的方式连接典型实验室储藏室中可用的元件和仪器，并获得实验室中经历的相同响应，包括故障。5)通过将相互连接的元件和对象与软件应用程序包无缝集成来模拟它们的性能。这些软件包将产生代表电流、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)为学生提供智能实验室助理，其将以模拟专家实验室助理的角色的方式回答学生的问题。7)将产生的UVL模块放在光盘上，并使这些模块在万维网上完全发挥作用。8)通过万维网、在适当的期刊上以及通过在著名会议上的演示来传播结果。在该项目中开发的框架可用作在其他工程课程以及物理科学中设计和实施现实虚拟实验室的模板。

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.
