Virtual reality (VR) technology has revolutionized science, technology, engineering, arts, and mathematics (STEAM) education by simulating real-world environments, offering innovative learning methods. This study focuses on designing an educational system within VR for Arduino UNO microcontroller development. Students engage in graphical programming and hardware integration of the Arduino UNO within VR environments, implementing intelligent control of farms and traffic. This approach helps students grasp practical applications of the Arduino UNO in real production contexts, further cultivating their programming skills and fostering innovative thinking. We conducted Arduino courses tailored for programming beginners, assessing the usability of EduCodeVR and its impact on students through learning outcome tests and VR system usability assessments. The results demonstrate that EduCodeVR, which uses STEAM education methodologies, effectively enhances users' comprehensive literacy and computational thinking, highlighting the significant potential of integrating VR programming courses into STEAM education. Through this innovative teaching approach, students not only acquire knowledge, but also enjoy the pleasures of immersive learning.

A systematic approach to scientific visualization

引用

ENGINEERING COMPUTATIONS 2006年第7-8期23卷 898-906页

作者： Radoiu, Dumitru Enachescu, Calin Adjei, Osei Petru Maior Univ Dept Comp Sci Targu Mures Romania Univ Halle Wittenberg Dept Comp & Informat Syst Luton Beds England

Purpose - Recent technological advances have created volumes of data such that, unless some effective methods are used to analyse them, they will be either wasted or under-examined for their useful information content. Scientific data visualization is an attempt to use graphical and numerical tools to extract information contained in data and hence to allow its analysis. This paper seeks to present a systematic approach to the development of tools for scientific data visualization. Design/methodology/approach - It is shown that the approach to implement these tools involves four major steps: description of a reference model, validation of the data process, description of the software component and the design and implementation of the visualization tool. Findings - This approach is substantiated by defining conditions suitable for scientific data visualization processes, in a relaxed manner. These conditions are subsequently refined more formally. Definitions and theorems of the proofs are succinctly discussed. Originality/value - The mathematical description of the visualization process is necessary to understand and maintain some significant reduction in errors in scientific visualization processes.

CONSTRAINT-BASED TOOLS FOR BUILDING USER INTERFACES

引用

ACM TRANSACTIONS ON GRAPHICS 1986年第4期5卷 345-374页

作者： BORNING, A DUISBERG, R UNIV WASHINGTON DEPT COMP SCISEATTLEWA 98195 TEKTRONIX INC BEAVERTONOR 97077

A constraint describes a relation that must be maintained. Constraints provide a useful mechanism to aid in the construction of interactive graphical user interfaces. They can be used to maintain consistency between data and a view of the data, to maintain consistency among multiple views, to specify layout, and to specify relations between events and responses for describing animations of interactive systems and event-driven simulations. Object-oriented techniques for constraint representation and satisfaction are presented, and a range of examples that demonstrate the practical use of static and temporal constraints for such purposes is presented. These examples include animations of algorithms and physics simulations, and constructing user-interface elements such as file browsers, views onto statistical data, and an interactive monitor or a simulated operating system.

作者： Hou, Yuemin Ji, Linhong Beijing Informat Sci & Technol Univ Dept Mech Engn Beijing Peoples R China Tsinghua Univ Dept Precis Instrument & Mechanol Beijing 100084 Peoples R China

Purpose - The aim is to map function into structure step-by-step. Design/methodology/approach - Using bio-inspired approach to investigate generic principle governing the formation of systems or artifacts by analogy with embryogenesis and using matrices and graphs to formalize design information. Findings - A six-stage design framework is proposed and represented as six models: the function model which interprets design requirements, the surrogate model which transforms the subjective intention into the objective property, the property model which illustrates basic constituents of property, the specification model which specifies abstract properties by concrete property values or equations, the feature model which transforms properties into the feature of topology and materials of the structure, and the parameter model which parameterizes the detail description of structure. The transformations between stages are achieved mainly by means of induction, duality, decision making and nonlinear programming. Research limitations/implications - Bio-inspired approach provides mechanisms to map function into structure. Practical implications - A normative framework for engineering design and system design. Originality/value - The framework distinguishes itself by biological approach, developmental process simulating to the development of embryo, induction and duality strategies to map, stages, as well as mathematical representation.

CONSISTENCY IN DATA-FLOW GRAPHS

引用

IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS 1991年第2期2卷 223-235页

作者： LEE, EA Department of Electrical Engineering and Computer Science University of California Berkeley CA USA

This paper explores analytical properties of programming languages with dataflow graph semantics. Such languages are currently used in certain application domains, such as digital signal processing, and a better analytical understanding of their properties may broaden their applicability. One of their most serious problems is that subtle inconsistencies between parts of the dataflow graph can be inadvertently created. These inconsistencies can lead to deadlock, or in the case of nonterminating programs, to unbounded memory requirements. Consistency is defined to mean that the same number of tokens is consumed as produced on any arc, in the long run. A token-flow model is developed for testing for consistency. The method is a generalization of consistency checks for synchronous dataflow (SDF) graphs [17]. Although inspired by the similar tests of Benveniste et al. [7], the method and the languages to which it applies are different.

Graph products with specified domains for configuration processing and formation of the adjacency matrices

引用

ENGINEERING COMPUTATIONS 2010年第1-2期27卷 205-224页

作者： Kaveh, A. Alinejad, B. Iran Univ Sci & Technol Ctr Excellence Fundamental Studies Struct Engn Tehran Iran

Purpose - Graph products are extensively used in the analysis and design of regular structures. It is often thought that these products are only applicable to regular graphs. The main aim of this paper is develop new products which are applicable to regular as well and non-regular structural models. Design/methodology/approach - New graph products are defined with specified domains. In these products the logical operations of the graph products are only performable in specified domains, and therefore these products can produce configurations which do not need to be regular. Findings - New graph products are defined and a general theorem is proved for the formation of their adjacency matrices. Originality/value - The presented graph products overcome the difficulty of employing graph products in structural mechanics, and in particular in space structures. The general theorem of this paper can efficiently be used in the formation of adjacency matrices of the structural models.

AN OVERVIEW OF A graphical MULTILANGUAGE APPLICATIONS ENVIRONMENT

引用

IEEE TRANSACTIONS ON SOFTWARE ENGINEERING 1988年第6期14卷 774-786页

作者： FISHER, G Division of Computer Science University of California at Davis Davis CA 95616

An environment to support the development and use of engineering applications is presented. The environment provides uniform support for a set of Pascal-class languages in which engineering and scientific applications are commonly written. The environment includes a dynamically multilanguage interpreter/debugger to aid in the interactive development of applications. For the application end user, the environment provides a graphical program interface based on the concept of a software control panel. Through a control panel, the user may interactively modify program parameters and exercise fine-grain control over program execution. The environment also includes a graphical design tool for constructing; executable block diagrams based on standard application programs. The control panel tool is integrated with the design tool, to provide a uniform interface to all levels of pro- gram execution. [ABSTRACT FROM AUTHOR]
