1A1-E27 表面筋電図を利用した手の動作認識と動作時の筋力推定

In Japan, the penetration of electric prosthetic hands is low, that is around 1%, and the hand is not popular. Authors have developed a myoelectric prosthetic hand which has high grasp force and 2-DOF wrist based on a survey of demands for prosthetic hands. This paper presents a novel myoelectric prosthetic hand and an artificial skin. The prosthetic hand is improved from the previous one. Experiments are performed to show characteristics of the prosthetic hand.

In the effort to a durable development, is put increasingly more emphasis on the reduction of pollution, of energy consumption, of carbon emissions for, both, private buildings and industrial buildings. One way to reduce this factor is the implementation of vertical vegetal walls with climbing plants or separated structures, so-called vertical gardens.The main aim of the research is to highlight the qualities of different types of vertical gardens existing in the market currently. The research focused, in addition, on the advantages and disadvantages of vertical garden systems from technical and visually point of view. To provide a comprehensive overview about the influence of environmental factors on vertical systems, were monitored specially designed modules in order to observe the loss of water and the growth of plants used in the construction of such systems. In the experiment have been utilized 11 species of plants and 9 planting substrate, different in terms of the degree of compaction. The test consisted of daily weighing of the evidence, for a period of two months (September and October 2011). The obtained results provide a comprehensive overview about the influence of environmental factors on vertical systems, on the loss of water and the growth of plants used in the construction of such systems.

For a myoelectric prosthetic robot hand to be useful in everyday life situations, an accurate mapping of the muscle EMG signals to each finger motion is required. In this paper, we propose a deep learning-based method for mapping the surface EMG signals to the hand gesture recognition. In our method, the EMG row data are used as input of a Convolution Neural Network (CNN) and the features of the EMG data are generated in the process of learning. The results show a good performance of CNN for most of 53 considered gestures. In addition, the trained CNN performed well also in real time situations mapping the EMG signals.

Our purpose is to clear whether the interferential current (IFC) method is useful for information transmission of a myoelectric prosthetic hand to the user. IFC stimulation is composed of two AC output waves. In previously, we demonstrated that IFC method using the two waves with different frequencies could vary the intensity of perceived stimulus. In the present study, we evaluated that the relationship between a movement of position of perceived stimulus and IFC method, using two waves with the same median frequency and a different phase. Moreover, we investigated the effects of a distance of recording electrodes from stimulating electrodes on a degree of interference of IFC with EMG signals. The movement of position of perceived stimulus was caused by the phase difference changing. IFC interfered with EMG signals. Especially, the interference of IFC with EMG of the muscle under stimulating electrodes was large. In contrast, when recording electrodes was distant from the stimulating electrodes, the interference of IFC was small. Moreover, the interference was eliminated by the low-pass filter (< 500Hz). These results support the usefulness of a combination of the IFC method with EMG recording system equipped with the low-pass filter as a sensory feedback system for myoelectric prosthetic hand.

We discuss the development method of a skeleton type myoelectric prosthetic hand by using a laser cutting machine. This myoelectric prosthetic hand has five concepts for practical application; (1) Five fingers, (2) Gripping operation using the five fingers, (3) Structure of the hand to the collision,(4) Structure in the operation of the rehabilitation training and (5) low price, saving weight. Results demonstrated these concepts capabilities of the skeleton type myoelectric prosthetic hand.

The i-LIMB hand is a novel upper limb myoelectric prosthetic hand with several joints in the fingers and thumb. This study aimed to determine whether this new device had more functionality than a more conventional myoelectric prosthetic hand with only a single joint between the thumb and two fingers. Therefore, a 45-year-old man with a wrist disarticulation used the i-LIMB hand and the widely used Dynamic Mode Control hand (DMC plus hand) in a test procedure that covered all functional levels of the International Classification of Function (ICF). Functional outcomes of the i-LIMB seemed to be lower than or equal to the DMC plus hand. The patient's satisfaction tended to be in favor of the i-LIMB. Compared to the DMC plus hand, the i-LIMB was more reliable when holding objects but had a lack of power and was less robust. We concluded that the i-LIMB hand has limited additional functionality compared to the DMC plus hand.

The need for innovations in developing creative prosthetic hands and terminal systems that take use of the most recent technology advances, to enhance device themes highly functional, robust, aesthetically acceptable, and less costly. This paper presents the design and manufacture technique of a tact hand, an anthropomorphic, open-source (O-S), Myoelectric Prosthetic Hand (MPH) for persons with transradial amputations in emerging state. The design process is based on balancing workability, cost, efficiency, durability, and effectiveness, and then manufacturing using 3D printing technology (3D-P). The findings showed that using lighter and hollow materials instead of rigid injection molded plastic materials reduced fatigue and pain caused by mass distributing to smoother tissues. But create the sensitivity hand system process, predict the sensitivity hand using qualitative and quantifiable events of enactment, and present samples of the usage of this hand to grab domestic things. The validation and findings were determined by comparing them to related studies, such as section four, where the functional usefulness of utilizing the hand to demonstrate a range of household items was discussed. Items like the water bottle and bottle cap, and the use of a 3-jaw chuck, key grip, and tool grip, were all simply understood by the tip. We combine electromyographic pattern recognition for motor control, contact reflexes, and sensory substitution to deliver input to the user. When compared to standard myoelectric prostheses that lack these features, the quality of rotation and other motions has also improved, and using contact reflexes and sensory substitution progresses grasping of delicate objects like an eggshell and a cup of water both with and without visual feedback. It can be shown that average intensity features (AIH) performed better than other feature sets (ACC <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\text{AIH}=0.952954668\%, \text{PAIH}=0.966836735\%,\ \text{SAIH}=0.979323844\%$</tex> ). We label our diagram process, estimate the Sensitivity hand <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\mathrm{S}\_\text{AIH}=0.979323844\%)$</tex> with together qualitative and measurable events of enactment, and show samples of this hand to grip domestic objects.

Despite the efforts to improve HCI issues, the users still find problems when interacting with applications. This naturally demands the need for help systems. But the construction of such systems depends on the availability of information (and the necessary reflections upon them) to compose its contents. This work investigates if the MoLIC language can contribute to the construction of help systems by checking the design reflections that this language leads a designer to exercise.

In this study, a feedback device of force sensation and temperature sensation for myoelectric prosthetic hand was developed. The feedback device is mounted on the upper arm of the prosthetic hand user. When an object was touched by the myoelectric prosthetic hand, hardness of the object is calculated based on the measured value of a pressure sensor and the displacement of the fingertip of the prosthetic hand, and temperature of the object is detected through a temperature sensor installed on the fingertip of the prosthetic hand. Then, the feedback device provides hardness of the object by winding a belt using a motor and produces temperature of the object by changing the temperature of a Peltier element. Thus, the force sensation and the temperature sensation are fed back to user's upper arm. Using the myoelectric prosthetic hand developed in our previous study, verification experiments were carried out to verify an effectiveness of the developed sensory feedback device, in which distinction of the temperature and hardness of the object was performed simultaneously from three different temperatures and three different hardness of the objects.

Restoring the hand functionality of partial amputees requires a myoelectric prosthetic hand, which is a robotic hand controlled by myoelectric signals from the skin surface and has the potential to restore human hand functionality. Most myoelectric hands have been developed for forearm amputees, while those for partial-hand amputees are few in number despite the higher numbers of the latter. Partial-hand amputees have limited hand functionality and cannot grasp and manipulate various objects in a manner comparable to individuals with a healthy hand; thus, they require a myoelectric hand. In this study, design issues were identified, and three-dimensional computer-aided design was used to propose an integrated skeleton and housing with a supporting socket. A passive thumb mechanism with motion in the remaining part of the hand was developed where the motion control system is based on the amputee’s muscles. An amputation system is proposed comprising mixed metacarpal and center-part cuts. A prototype was constructed, and its gripping functionality was evaluated. The results demonstrated an enhanced gripping performance compared to the non-use of prosthetics, which attests to the viability and effectiveness of the system.

In this paper, recognition of finger operations via surface EMG is discussed. We have developed a myoelectric prosthetic hand with thumb and index finger, so far. In order to control each finger of the developed myoelectric prosthetic hand independently, using the neural network, identifier which classifies four finger operations, namely flexion and extension of the thumb in metacarpophalangeal (MP) joint and flexion and extension of the index finger in MP joint, was constructed. The recognition of each finger operation was performed using the four patterns of the neural network based identifiers in which the recognition method of finger operations is different each other, and the results were compared.

In the last decade, the development and integration of the life of information technology society has affected the system of public governance. Key aspects of organizing modern urban development, management and planning that encompass different measurements: effective management, stability, environmental friendliness, innovation and understanding of the «Smart City» concept. «Smart City» is a digital toolkit (system), in which the city аdministration interact with the community and the city's infrastructure. As the basic tools of «Smart City» we can consider software and hardware complexes that are the part of the components (applications, software solutions, dedicated services, etc.), that perform specific typical operations for solving certain individual functions and form the overall architecture of the system. A significant barrier for the development of digital interference in Ukraine is a lack of clear classification of «Smart City» warehouse tools. One of the most important ways for systematization is the general classification of «Smart City» tools. The purpose of the article is the theoretical and methodological substantiation of the classification of «Smart City» tools. The article proposes to define the classification method as a set of rules for the creation of classification systems, as well as their coincidence. The proposed facet method most closely matches the system of classification of «Smart City» tools and allows to systematize a large set of objects. It is substantiated that using the facet method it is possible to construct a classification system of «Smart City» tools with flexible scaling at each level of such structure. The structure of classification of basic functions of public administration bodies is determined. The basic digital interactions of public intervention agencies (G - government) with the company (B - business) and citizens (C - citizen) are selected based on the levels of interaction of subjects and objects of electronic service provision. This will make it possible to formulate the first basic classification level depending on a certain initial position of objects in system. In order to determine the interaction levels, it is suggested to introduce index of the «Smart City» solutions, with the positioning of the system component by the classifiers. Based on the facet principle and defined types of fields, the basic system of classification «Smart City» tools was built. Having defined the tool of classification it becomes possible to describe and formaloze the inter-system interconnections at the level of data exchange between different components and subsystems. It expands the possibilities of implementation, cloning and scaling up successful technical, technological and managerial decisions. The proposed classification is a supersystem and does not affect internal architecture of specific systems and is appointmed, first of all, for the construction and standardization of inter-system interactions and systematization of «Smart City» tools. As a further development of issues we see the development of standardization and «Smart City» tools at the state level, the study of the world's experience in the implementation of «Smart City» to determine the recommendations for the development and construction of such systems.

In these lecture notes we explain how multi-user web applications can be developed in a programming style that favors tasks as main building block for the construction of such systems. A task is work that has to be performed by human-beings and computers working together on the internet. This concept has been implemented in the iTask framework as a monadic combinator library that is embedded in the pure and lazy functional programming language Clean. These lecture notes consist of many examples and exercises, and also discusses the foundation of both the iTask system and task-oriented programming.

Touchpads, haptics and gestures are becoming popular user-interfaces in modern electronic gadgets. In this project, we propose to use a touch pad to construct a HAM radio interface. Low-power, short-range wireless communication interfaces which have become available with modern microcontrollers enable the construction of such systems which can allow users to exchange information within buildings. While Morse code was invented for telegraphy, its simplicity allows a person with physical disability to use it more effectively than a keyboard-based interface. Thus, such an interface can be useful in rehab centers, old-age homes and hospitals. Security systems are yet another domain where Morse code can be gainfully employed. Since the user must make use of touch, drag and release operations for Morse code signaling, it is difficult to prescribe any strict guidelines on the length of the drag or the time gap between two drags. Multiple users of the system will use the system at different speeds. We propose the use of Fuzzy logic with elements of machine learning to reduce the chances of misinterpreting the Morse code and adapting to different users. In order to demonstrate our project, we used the MSP430F5529 development kit from Texas Instruments which comes with a touch-pad, an LCD screen and an RF interface. The system reported in this paper is cost-effective, low-power, and meets the real-time speed requirements of the application.
