<p>Information technologies, such as IoT, artificial intelligence (AI), and virtual reality (VR), have seen so much development that there is now a wide variety of digital equipment incorporated into the infrastructure of daily life. From the agrarian society (Society 1.0) through the information society (Society 4.0), humankind has created farmlands and cities by structuring natural environments physically and has built information environments by structuring them informationally. However, despite the rapid development of information environments, it may be fair to say that the perspectives of the human body have not changed at all since the industrial revolution.</p><p>In the context of these recent technological developments, greater attention is being paid to human augmentation studies. These studies aim for a new embodiment of "human-computer integration," one which can physically and informationally compensate or augment our innate sensory functions, motor functions, and intellectual processing functions by using digital equipment and information systems at will, as if they were our hands and feet. It has also been proposed that the technical systems that enable us to freely do what we want by utilizing human augmentations be called "JIZAI" (freedomization) as opposed to "automation."</p><p>The term "JIZAI body" used in these studies represents the new body image of humans who will utilize engineering and informatics technologies to act at will in the upcoming "super smart society" or "Society 5.0." In these studies, human augmentation technologies are an important component of JIZAI, but JIZAI is not the same as human augmentation. JIZAI is different in scope from human augmentation, as it aims to enable humans to move freely among the five new human body images: "strengthened sense" (augmented perception), "strengthened physical body" (body augmentation), "separately-designed mind and body" (out of body transform), "shadow cloning," and "assembling." In the society of the future where JIZAI bodies widely prevail, we will use technologies that enable us to do what we have failed at or given up due to limitations of our physical bodies. We believe that a future society, one in which aging does not reduce our capabilities but instead increased options give us hope, can be realized. This special issue, consisting of two review papers and twelve research papers, deals with diverse and wide-ranging areas, including human augmentation, robotics, virtual reality, and others. We would like to express our sincere appreciation to all the authors and reviewers of the papers contributed to this special issue and to the editorial committee of the Journal of Robotics and Mechatronics for their gracious cooperation.</p>

<p>This paper focuses on "play-biting" as a touch communication method used by robots. We investigated an appropriate play-biting behavior and its effect on interaction. The touching action has positive effects in human-robot interactions. However, as biting is a defenseless act, it may cause a negative effect as well. Therefore, we first examine biting manner and the appearance of the robot using a virtual play-biting system in Experiment 1. Next, based on the result of experiment, the play-biting system is implemented in a stuffed animal robot. We verified the impressions created by the robot and its effect on mitigating stress in Experiment 2. Consequently, the play-biting communication gave positive and lively impression, and effect of reducing the physiological index of stress, in comparison to only touching the robot.</p>

<p>Clustering is the task of dividing an input dataset into groups of objects based on their similarity. This process is frequently required in many applications. However, it is computationally expensive when running on traditional CPUs due to the large number of connections and objects the system needs to inspect. In this paper, we investigate the use of NVIDIA graphics processing units and their programming platform CUDA in the acceleration of the Euclidean clustering (EC) process in autonomous driving systems. We propose GPU-accelerated algorithms for the EC problem on point cloud datasets, optimization strategies, and discuss implementation issues of each method. Our experiments show that our solution outperforms the CPU algorithm with speedup rates up to 87X on real-world datasets.</p>

<p>This paper proposes a method for classifying informative reviews based on personal values. Reviews of an item are useful for a user who is considering purchasing it. However, it is difficult for readers to find informative reviews from vast amount of reviews because of existence of too many uninformative reviews. This paper supposes that the value of a review is affected by reader-dependent and independent factors. Typical uninformative reviews in terms of reader-independent factor are copy-and-paste reviews, which do not provide any readers with useful information for their decision-making. On the other hand, it is supposed different readers regard different reviews as informative, which is affected by their personal values. This paper focuses on such a reader-dependent factor, and proposes a methods for classifying informative reviews based on reader's personal value. Experiments are conducted using actual review data provided by Rakuten Inc., of which the results show about 0.7 of average accuracy is achieved. Furthermore, it is also shown proposed method can model judging criteria common to those who have similar personal values.</p>

<p>This paper describes a wearable encounter-type haptic device suitable for combined usage with a visual display. The features of the device lie in a driving mechanism that enables an encounter-type haptic display and the compact implementation of the entire device including the driving mechanism. The driving mechanism displays a natural haptic sense based on a smooth transition between follow-up and constraint of finger movements. The compactness is important because it contributes to preserving the quality of visual information when used together with a visual display. To test the basic performance of the device, the response of the driving mechanism was evaluated. The haptic display function was evaluated by a simulation in which the device is used to touch an object in a computer graphics (CG) space.</p>
