Electroencephalography (EEG) is a well-known, non-invasive method for monitoring and recording electrical activities of the human brain. Problem: EEG signal visualization, manipulation, analysis, and classification are essential for clinical experts, doctors, and researchers to make certain decisions. So, there is a need for a toolbox that can provide such functionalities with a user-friendly graphical user interface (GUI); availability may be commercial or open-source. Aim: This paper describes the proposed and developed open-source EEG VMAC Toolbox, which provides an interface with features including a series of state-of-the-art methods for EEG signal analysis. Method: The main menu options of EEG VMAC Toolbox are - 1) File, 2) Signal Visualization, 3) Filtering, 4) Signal Decomposition, 5) Feature Reduction, 6) Feature Extraction, 7) Label, 8) Classification Models, and 9) Help. Each menu of the toolbox contains several functionalities. In addition to these nine menus, a file conversion option is available at the bottom of the toolbox. EEG VMAC Toolbox integrates all major state-of-the-art functionalities for EEG signal visualization, manipulation, analysis, and classification, which would be a valuable addition to the current literature. Results and Findings: The EEG VMAC Toolbox has been developed using Python programming language and tested over the CHB-MIT EEG Scalp EEG dataset, a benchmark dataset for seizure detection. So, this toolbox has a provision to bring psychologists, neuroscientists, clinical experts, and EEG researchers on the same platform to pursue extensive investigation and research for better reach.

Today, Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) technologies are becoming fundamental across a wide variety of application domains. All these technologies fall under the Extended Reality (XR) spectrum. Areas in which XR technologies and, in particular, immersive experiences have been successfully introduced are expanding daily, from traditional areas, such as entertainment and video game production, to novel scenarios, such as industry, healthcare, smart cities, and autonomous vehicles, to mention a few. The spread of XR and VR is also driven by technological advancements that are making new ways of operating within virtual experiences easier, and sometimes even possible. In particular, the availability of new hardware and software tools make the use of '3D reconstructions', 'digital twins' and 'simulations' commonplace in many XR and VR applications. For example, the possibility to leverage networks with higher bandwidth than never before and lower latency makes it possible to transmit the amount of data needed for massive, real-time digital twins, whereas high-performance hardware enables the reconstruction of high-fidelity digital objects and environments, while lowering the time needed for high-demanding simulations. The aim of the 3D Reconstruction, Digital Twinning, and Simulation for Virtual Experiences (ReDigiTS) workshop is to bring together researchers, practitioners, educators, and students to share ideas and promote further work in this growing area of 3D reconstruction, digital twinning, and simulation in VR and related technologies. © 2023 IEEE.

It has been shown in previous studies that haptic guidance improves the learning outcomes of handwriting motor skills. In this paper, we present a comparison between full guidance and partial guidance using a haptic learning tool which supports these two modes. The full guidance mode leads the user along a pre-recorded trajectory, whereas the partial guidance mode allows the user a free movement and provides corrective forces if they deviate significantly from the desired path. Experimental results with 22 participants demonstrated that there is no significant difference between partial haptic guidance and full haptic guidance for improving learning outcomes, while both have significantly improved the learner's performance compared to no haptics feedback. However, when the two modes are combined, partial guidance followed by full guidance yielded better overall performance. We conclude the paper by summarizing our findings and providing perspectives for future work. © 2017 IEEE.

For more than ten years, researchers have been developing software-based methods for analyzing the movements of orchestral conductors. Beginning with the Conductor's Jacket research project, researchers have combined wearable sensors with face-on video recordings to improve tracking and understanding of the structure inherent in the gestures. Building upon more recent work employing computer vision, the current project refines the methods for tracking the hands and visualizes the data in a way that reveals more of the underlying structure in an easier-to-view fashion. Such improved methods will enable more specific understanding of the functions of conducting gestures, and allow for more concrete applications of those gestures to interactive conducting systems for public exhibits, video games, and integrating dynamic audio enhancements to live concerts.

This paper presents findings of an exploratory, qualitative study of professional web and graphic designers who regularly write computer programs. These participants have a wide variety of educational backgrounds, including some who had a few classes in computer science. Our participants report having found a career in which they enjoy being both creative and technical. They want to learn more about computing, but do not find computing curricula as meeting their needs. We discuss their perceptions of the computing discipline, motivational aspects of their jobs, and their interest in learning more about computing. We also consider implications for computing curricula if we were to try to meet the needs of these professionals who are unlikely to appear in our current classes. Copyright 2010 ACM.

The four women on this panel devote their scholarship to computer games. We love games of all sorts. We love to play them and build them. Both activities require creative, inquisitive, problem solving that is essential to good computer science. We also love to use games as vehicles for teachingimportant ideas about computer science and software design. At least one of us is a hard core gamer. And one of us is old enough to have played, as an adult, the very first video games. So it is with just a bit of frustration that we repeatedly hear that "boys like games and girls like stories. Granted, that is hyperbolic, but in subtler ways the current trend to use games as a vehicle to attract students to computer science is focused on a narrow perception of what a video game is, as well as a narrow perception of who a "gamer" is. The bifurcation of focus: that to attract a particular kind of male to computing through games, and a particular kind of female through media and storytelling, is quite frankly, in the words of a panel member, "hogwash" We four love both games and interactive stories. From our scholarship and our classroom experience we know that girls do like games, and boys like stories. This calls into question how undergraduate programs in computer science, media, game design and information science embrace or reject "games" in their core. The CS community must consider the assumptions being made both about what game design is, and how it can be used as a vehicle to fulfill a pedagogic agenda. This panel will address four important issues: (1) Perceptions of what computer science and game design are, (2) Taking a broad view of what a game is, and focusing on the creative process of game design (3) exploiting the range of game genre to fulfill learning objectives, and (4) Assessing whether or not those learning objectives have been reached.

Scratch [4] is both a social computing environment and a rich programming language with a highly supportive interface. Although originally intended for an audience younger than college freshman, there is growing interest in using Scratch at the undergraduate level as a gentle introduction to hard concepts. David Malan and Henry Leitner first presented their experience teaching Harvard introductory CS courses with Scratch at SIGCSE two years ago [3]. At SIGCSE 08 John Maloney and Ursula Wolz provided the SIGCSE community with an overview of the language and the social computing website. John also presented research results at SIGCSE 08 on the popularity of programming among young people in a community clubhouse setting [4]. The kids preferred to program rather than play computer games. At both Harvard and The College of New Jersey (TCNJ) we have seen similar phenomena where the flexibility, simplicity and ease with which students can make their programming experience highly personal in a supportive community, actively engages them in the process of learning to program regardless of ethnicity or gender. The very successful Scratch@MIT conference in July 2008 brought together educators from around the world who realize that Scratch appears to be an intriguing gateway into the discipline of programming. The social computing website supports over 100,000 registered members, who have posted approximately 200,000 projects that include approximately 5 million scripts (programs). The archive of programs includes very sophisticated computer code written by talented, well-trained and creative programmers. Yet the language is, by design, extremely simple. It is not, and never was intended to be a "kitchen sink" kind of language. However, a growing community continues toproduce an unanticipated range of examples of how computer code, creatively developed, can produce wonderful games, stories, art, science simulations and mathematical models.
