An architecture for new models of online laboratories: Educative multi-user gamified hybrid laboratories based on virtual environments 在线实验室新模式的架构:基于虚拟环境的教育多用户游戏化混合实验室
L. Rodríguez-Gil, J. García-Zubía, P. Orduña
Research in virtual environments, gamification and serious-games suggests that those tools can be very effective for education, and that in certain contexts they provide unique advantages. Recent advances are making the technologies they are based on more widespread, with technologies such as 3D becoming widely available through web browsers and even in mobile devices. Efforts are being dedicated in the area of online hybrid laboratories (laboratories with both virtual and remote components) to evaluate whether it is possible to also incorporate concepts such as virtual environments, serious-gaming, or even collaboration between its users, and what advantages would that provide. There have been some promising results so far, but there are still many possibilities to explore, and the area is relatively novel. This dissertation aims to advance the field by creating and testing the viability of new complex online laboratory models which leverage those new features, and by creating an architecture and providing methodologies to facilitate the creation of laboratories which incorporate them, and which are reliable and interoperable with different Remote Laboratory Management Systems. Additionally, a particular implementation of the proposed architecture will be developed, and generic open tools provided.
对虚拟环境、游戏化和严肃游戏的研究表明,这些工具对教育非常有效,在某些情况下,它们提供了独特的优势。最近的进步使它们所基于的技术更加普及,3D等技术通过网络浏览器甚至移动设备广泛使用。在线混合实验室(拥有虚拟和远程组件的实验室)领域正在努力评估是否有可能将虚拟环境、严肃游戏甚至用户之间的协作等概念纳入其中,以及这样做会带来什么优势。到目前为止,已经有了一些令人鼓舞的结果,但仍有许多可能性有待探索,而且该领域相对较新。本论文旨在通过创建和测试利用这些新功能的新的复杂在线实验室模型的可行性,并通过创建架构和提供方法来促进创建包含这些新功能的实验室,并且这些模型可靠且可与不同的远程实验室管理系统互操作,从而推进该领域。此外,还将开发所建议的体系结构的特定实现,并提供通用的开放工具。

Virtual environment for instrumented glove 仪表手套的虚拟环境
R. Tavares, Pedro Jose Souse, Paulo Abreu, M. T. Restivo
This work describes a virtual environment for an instrumented glove to promote hand rehabilitation. The virtual environment comprises a 3D model of a hand that uses an instrumented glove with bend sensors to track the fingers' motion and an IMU (inertial measuring unit) to track the hand position and orientation. An interface device is responsible for routing the data from the instrumented glove's sensors and from the IMU to the virtual environment. The virtual environment connects to the interface device either by cable (USB) or wirelessly (Bluetooth LE). The virtual application was developed in Unity 5 and is multiplatform. This demo presents a functional virtual environment that interfaces with an instrumented glove and an IMU to provide a faithful virtual representation of the user's hand.

Cloud-based remote virtual prototyping platform for embedded control applications: Cloud-based infrastructure for large-scale embedded hardware-related programming laboratories 用于嵌入式控制应用的基于云的远程虚拟原型平台:用于大规模嵌入式硬件相关编程实验室的基于云的基础设施
Stephan Werner, Andreas Lauber, J. Becker, E. Sax
The design and test of Multi-Processor System-on-Chip (MPSoCs) including software is one of the biggest challenges in today's system design. This applies in particular when short time-to-market constraints impose serious limitations on the exploration of the design space. The use of virtual platforms can help in decreasing the development cycles. In this paper, we present a cloud-based environment allowing the design of virtual platforms and prototyping of the system including complex software with prerecorded data or testbenches. Afterwards, the created design can also be synthesized for Xilinx FPGAs. Additionally, this paper presents the use of this remote virtual prototyping environment in a hardware-related programming laboratory with more than 350 participating undergraduate students. This large number of attendees leads to a lot of issues regarding the supervisory relationship as well as providing enough hardware resources in terms of boards. Nevertheless, we want to give the students hands-on experience when programming an embedded system on an FPGA-board. The cloud-based infrastructure allows us to respond to these difficulties by implementing a Software-in-the-Loop simulation based on an instruction set simulator. Doing so the students can design and implement their codes for the targeted architecture and prototype and debug it on a virtual platform. Since the course is mandatory we expect many students with limited experience about hardware-related programming. In this paper we show that especially these students will profit from the additional possibilities which are offered by a remotely available virtual prototyping platform.
包括软件在内的多处理器片上系统(mpsoc)的设计和测试是当今系统设计中最大的挑战之一。这尤其适用于短时间上市限制对设计空间的探索造成严重限制的情况。使用虚拟平台可以帮助缩短开发周期。在本文中,我们提出了一个基于云的环境,允许设计虚拟平台和系统原型,包括具有预先录制数据或测试台的复杂软件。然后,创建的设计也可以用于Xilinx fpga的综合。此外,本文还介绍了该远程虚拟原型环境在一个与硬件相关的编程实验室中的使用,该实验室有350多名本科生参与。这么多的与会者导致了很多关于监督关系的问题,以及在董事会方面提供足够的硬件资源。然而,我们希望给学生在fpga板上编程嵌入式系统的实践经验。基于云的基础设施允许我们通过实现基于指令集模拟器的软件在环仿真来应对这些困难。这样,学生就可以为目标架构设计和实现他们的代码,并在虚拟平台上进行原型和调试。由于课程是强制性的,我们希望许多学生对硬件相关编程经验有限。在本文中,我们表明,特别是这些学生将受益于远程可用的虚拟原型平台提供的额外可能性。

"Virtual" experimentation on algorithm optimality 算法最优性的“虚拟”实验
J. Velázquez-Iturbide
Learning programming in general, and algorithms in particular, demands to carry out a variety of practical activities, including experiments. In this paper, we summarize our instructional experience experimenting with algorithm optimality and we discuss the main issues raised. First, we introduce experimentation with algorithms. Afterwards, we briefly present the tools we developed for experimentation with optimality (GreedEx, GreedExCol and OptimEx) and we illustrate the kind of results that are expected by using a number of (exact and nonexact) greedy algorithms. We also describe our experiences in actual courses. Of special relevance are the students' difficulties and misconceptions we identified, as well as the interventions we performed to remove them. Finally, we relate these experiences with a number of relevant educational issues, namely learning goals, instructional methods, and how to address students' difficulties.
学习一般的编程,尤其是算法,需要进行各种各样的实践活动,包括实验。本文总结了算法最优性实验的教学经验,并讨论了所提出的主要问题。首先,我们介绍算法实验。之后,我们简要介绍了我们为最优性实验开发的工具(gredex, gredexcol和OptimEx),并说明了使用许多(精确和非精确)贪婪算法所期望的结果。我们还描述了我们在实际课程中的经验。特别相关的是我们发现的学生的困难和误解,以及我们为消除它们而采取的干预措施。最后,我们将这些经验与一些相关的教育问题联系起来,即学习目标、教学方法以及如何解决学生的困难。

Classifying online laboratories: Reality, simulation, user perception and potential overlaps 分类在线实验室:现实,模拟,用户感知和潜在的重叠
P. Orduña, L. Rodríguez-Gil, J. García-Zubía, O. Dziabenko, I. Angulo, U. Hernández, Esteban Azcuenaga
Students of technological fields must practice so as to properly learn a particular field. There are different ways to practice: hands-on-lab in a real environment or a mockup, datasets (and tools for analyzing these datasets), or simulations. Each solution provides different advantages and disadvantages. For example, students might not prefer simulations since they do not always provide accurate real values (and when testing in a real laboratory results differ and the engagement might be higher), but they might be more affordable than real laboratories (depending on the field, there might not be any other affordable solution than a simulation). Datasets of recorded measurements are an equidistant point, where costs are lower and data is real, but no interaction is performed by the users with the reality. When creating remote laboratories, a system that enables students access the final equipment is usually used, but this might not be the best option. Sometimes, every potential input could be recorded and used in the future as a dataset to let users access this laboratory in a scalable way, and hybrid solutions could also be achieved. The focus of this contribution is to classify online laboratories from this perspective.
技术领域的学生必须通过实践才能正确地学习某一特定领域。有不同的实践方法:在真实环境或模型中,在实验室中动手,数据集(和分析这些数据集的工具)或模拟。每种解决方案都有不同的优点和缺点。例如,学生可能不喜欢模拟,因为它们并不总是提供准确的真实值(当在真实实验室中测试结果不同时,参与度可能更高),但它们可能比真实实验室更实惠(取决于领域,可能没有比模拟更实惠的解决方案)。记录的测量数据集是等距点,在那里成本较低,数据是真实的,但用户与现实没有交互。在创建远程实验室时,通常使用一个允许学生访问最终设备的系统,但这可能不是最好的选择。有时,每一个潜在的输入都可以被记录下来,并在未来作为一个数据集使用,让用户以可扩展的方式访问这个实验室,也可以实现混合解决方案。这篇文章的重点是从这个角度对在线实验室进行分类。

The Mach-Zehnder Interferometer — A smart remote experiment based on a software template Mach-Zehnder干涉仪——基于软件模板的智能远程实验
Wissam Halimi, C. Salzmann, Denis Gillet
Hands-on laboratory sessions are one of the pillars of science and engineering education. It is reputed that institutions find it difficult to provide enough laboratory setups that cover all taught scientific topics due to logistical and budgetary limitations. With the recent advances in web technologies enabling real-time interaction, remotely accessing physical devices became possible, and so the rise of remote experimentation as a solution to the mentioned limitations. The development and deployment of remote laboratories is still a tedious process for lab providers, given the need to write new applications for each new lab. In this paper, we propose a software template for lab providers that will alleviate some of their concerns by following the Smart Device Paradigm and Specifications and abiding to software engineering rules to produce a reusable and flexible solution. We will show how this in-progress template can be used for implementing a remote Mach-Zehnder Interferometer.
动手实验课程是科学和工程教育的支柱之一。据说,由于后勤和预算的限制,各机构发现很难提供足够的实验室设施来涵盖所有的科学教学主题。随着最近web技术的进步,实时交互成为可能,远程访问物理设备成为可能,因此远程实验的兴起作为上述限制的解决方案。对于实验室供应商来说,远程实验室的开发和部署仍然是一个繁琐的过程,因为每个新实验室都需要编写新的应用程序。在本文中,我们为实验室供应商提出了一个软件模板,通过遵循智能设备范例和规范并遵守软件工程规则来产生可重用和灵活的解决方案,该模板将减轻他们的一些担忧。我们将展示如何将这个正在进行的模板用于实现远程马赫-曾德尔干涉仪。

Deploying web-based control laboratory using HTML5 使用HTML5部署基于web的控制实验室
Zhongcheng Lei, Wenshan Hu, Hong Zhou
The achievements in Internet and communication technology make remote learning and online laboratory possible in the last few decades, which not only provides opportunities for people in rural areas in developing countries, but also offer simple alternatives for those who already have access to educational resources. With the evolution of Web technologies, it is relatively easy to facilitate laboratory deployments, thus, more and more different online laboratories emerge. However, Hyper Text Mark-up Language (HTML5) and related standards (e.g. WebGL, CSS3) which are future trends and provide full-featured environment are rare so far. In this paper, a new HTML5 version of Networked Control System Laboratory (NCSLab) which has been developing for over 10 years since 2006, is introduced. The 3D version of NCSLab has been developing for almost 5 years in Wuhan University (WHU), whose rendering solution is changed from Flash 3D engine to HTML5. Therefore, Flash player plug-in is no more needed. User can login the system to perform experiments with better user experience since most Web browsers are compatible with HTML5.
近几十年来,互联网和通信技术的成就使远程学习和在线实验室成为可能,这不仅为发展中国家农村地区的人们提供了机会,也为那些已经获得教育资源的人提供了简单的选择。随着Web技术的发展,实验室的部署相对容易,因此出现了越来越多不同的在线实验室。然而,超文本标记语言(HTML5)和相关标准(如WebGL, CSS3)是未来的趋势,提供全功能的环境,目前还很少。本文介绍了网络控制系统实验室(Networked Control System Laboratory, NCSLab)的HTML5新版本,该版本自2006年开发至今已有10多年的历史。《NCSLab》的3D版本在武汉大学(WHU)已经开发了近5年,其渲染解决方案从Flash 3D引擎改为HTML5。因此,不再需要Flash播放器插件。由于大多数Web浏览器都兼容HTML5,用户可以登录系统进行实验,获得更好的用户体验。

Results of first evaluation, performed by trained secondary vocational schools teachers, are disused in the second section. Following is brief overview of the evaluations planned to be performed by students from Serbian partner universities and by students from selected secondary vocational schools. The planned evaluation that will be performed by experts from EU partner universities is described in more details in the last section.
