Surface electromyography (sEMG) has often enabled operators to generate electrical muscle signals in order to control robotic arms or prosthetics. Alternatively, sEMG has recently been employed to control other types of equipment such as computer keyboards, which indicates that sEMG-machine interfaces can be a means of controlling actual automobiles or computer-simulated automobiles. Therefore, the current study pertains to a sEMG-controlled virtual car in a PC platform driving simulator. A method is proposed for implementing a sEMG-machine interface that controls the steering of the virtual car.

human space exploration has never been more exciting than it is today. human presence to outer worlds is becoming a reality as humans are leveraging much of our prior knowledge to the new mission of going to Mars. Exploring the solar system at greater distances from Earth than ever before will possess some unique challenges, which can be overcome thanks to the advances in modeling and simulation technologies. The National Aeronautics and Space Administration (NASA) is at the forefront of exploring our solar system. NASA's human Research Program (HRP) focuses on discovering the best methods and technologies that support safe and productive human space travel in the extreme and harsh space environment. HRP uses various methods and approaches to answer questions about the impact of long duration missions on the human in space including: gravity's impact on the human body, isolation and confinement on the human, hostile environments impact on the human, space radiation, and how the distance is likely to impact the human. Predictive models are included in the HRP research portfolio as these models provide valuable insights into human-system operations. This paper will provide an overview of NASA's HRP and will present a number of projects that have used modeling and simulation to provide insights into human-system issues (e.g. automation, habitat design, schedules) in anticipation of deep-space exploration.

Macau is a tourist city with its distinctive architecture and attractions. The development of the gaming industry has attracted many tourists to travel to the area. One of the most famous landmark in Macau is the Ruins of St. Paul. The 100-year-old historical monument just reserved a wall after three major fire and reconstructions and standing outside rely on human maintenance. Therefore, sustainable preservation is an important issue today. Users can quickly search for historical sites and digitally saved image data through their smart phones. At present, mobile APP rarely uses stereoscopic perspectives for interactive operations. The 4DAGE company's 4DKanKan technology can quickly create virtual reality and save historic site in mobile devices to interact with it. The 4DKanKan can also integrate mobile guide and navigation. Therefore, this study intends to use this technology to design and link to the Web. It can continue to extend to other attractions or museum collections in the future. There are systematic and digital representations of different types of monuments that have the concept of sustainable management.

For virtual evaluation of universal design products, it is necessary to synthesize natural grasps for various hands including those with limited range of motion (ROM). In this paper, we study synthesizing grasps for digital hands with limited ROM in their thumbs' joints. We apply a contact-region-based method for grasp synthesis to this problem. In our previous study, two types of grasps were observed under the limitation of the thumb's ROM. One was a type that used the lateral region of the thumb, and the other was a type that used he same contact regions as healthy hands. In this paper, grasps are synthesized for two objects using three hand models whose lengths are different. With the same input information as the healthy hand, it is not possible to synthesize the grasps for the ROM-limited hand. On the other hand, when grasps are synthesized by changing the information about grasping target points of the thumb and the palm, feasible grasps for the ROM-limited hand can be found. For a camera object, the grasp using the thumb's radial region is automatically synthesized without changing the specified contact region. Also, for a spray object, a grasp that uses the same contact region as the healthy hand is synthesized. These results demonstrate our method can synthesize natural grasps even for ROM-limited hands, which will contribute to universal product design.

There is an imminent need to remedy the 'skills gaps' in the digital manufacturing (DM) sector as evident from the Bureau of Labor Statistics projections pointing to a decline in traditional manufacturing jobs accompanied by marked growth in digital- and computer-driven manufacturing jobs. With proven advantages such as cost benefits, material conservation, minimized labor, and enhanced precision, manufacturing industries worldwide are adapting to digital manufacturing standards on a large scale. In an effort to remedy the lack of well-defined DM career pathways and instructional framework, our NSF ATE (Advanced Technological Education) project MANEUVER (Manufacturing Education Using Virtual Environment Resources) is developing an innovative pedagogical approach using virtual reality (VR). This multimodal VR framework DM instruction targeted at 2-year and 4-year manufacturing programs, facilitates the development of VR modules for multiple modes such as desktop VR, Augmented VR, and Immersive VR. The advantages of the virtual reality framework for digital manufacturing education include: significant cost reduction, reduction in equipment and maintenance costs, ability to pre-visualize the product before manufacturing. This paper introduces the design and development process of VR education tool to simulate three different additive manufacturing machines, e.g., LutzBot™, FormLabs™, and UPrint™ and different 3D printing technologies e.g., fused deposition modeling, and selective laser sintering to allow the students experience the materials and equipment needed to create the same part using different types of equipment and different types of technology. © American Society for engineering Education, 2018.

This paper presents a model of environmenthuman body interaction, which is critical for us to perform balanced motions such as locomotion and activities of daily living while standing. Specifically, movement smoothness and stiffness are quantitatively represented by an impedance between environment and body (ENV-BODY impedance) based on the concept of mechanical impedance, which is commonly used in robotics. The ENV-BODY impedance model considers a spring and a damper to represent the behavior of the center of pressure with respect to the ground reaction force. The model parameters are obtained from experimentally measured motion data. In addition, real-time feedback is applied for intervening the ENV-BODY impedance model by either attenuating (in-phase mode) or amplifying (anti-phase mode) the displacement of the center of pressure. Experimental results show that the proposed ENV-BODY impedance model suitably reflects the relationship between ground reaction force and center of pressure during static standing, and reconstructs the centerof-pressure acceleration with average error of 4.1E-01 mm/s(2). Furthermore, the stiffness is smaller at the in-phase than at the anti-phase mode, thus being consistent with the expected mechanical stability. This model could be applied to training programs for evaluating movement smoothness and roughness using real-time motion measurement/analysis and environment control technology.

Blockchain technology becomes the key solution to provide trust and security without any need for a central supervisory authority to validate the transactions. By now, it plays a key role in the digital transformation of several processes and industries with varying application use cases. To promote the wide adoption of blockchain technology we need mechanisms to identify the digitizability level of the given regulations to smart contracts and mechanisms to specify which blockchain technology is best suitable for the given regulations. In this work, we propose a modeling approach that supports the automated analysis of human-readable regulation representations by suggesting how much percentage of regulation is digitizable and the suitable blockchain environment to design the application. We identify smart contract components that correspond to real-world entities and its pertaining clauses and its digitizability property. With selected examples, we explore this capability and discuss our future research directions on smart contract generation according to the recommended environment. © 2018 ACM.
