Hype D-Live: XR Live Music System to Entertain Passengers for Anxiety Reduction in Autonomous Vehicles
No full textPassengers in autonomous vehicles enjoy the comfort of being free from driving tasks, but they inevitably experience anxiety caused by autonomous vehicle stress (AVS). AVS encompasses vehicle behavior stress due to unpredictable acceleration, and external environmental stress due to potential collisions. Past research has explored approaches to improve passengers’ comfort through behavior control and information presentation. However, methods that utilize stressful vehicle behavior in Extended Reality (XR) entertainment to distract from AVS-related anxiety are limited. Hence, the goal of this study was to maximize passenger comfort in automated vehicles. To achieve this goal, we implemented an XR entertainment system that utilizes vehicle behavior and evaluated its effect on reducing anxiety. In this study, we proposed “Hype D-Live”, an XR live music system designed to reduce anxiety by providing multimodal visual, auditory, force, and vestibular stimuli using a hemispherical display and motion platform mounted on a vehicle. We developed system functions to adjust the force and vestibular senses according to the excitement level of the music and the direction of stressful acceleration and to reproduce moshing, a characteristic behavior at live music venues. However, we hypothesized that passengers might not fully enjoy the entertainment and could experience anxiety if the video content makes them aware of the external environment. Therefore, we conducted an experiment with a within-participant design, involving 24 participants (14 males and 10 females), comparing 3 types of video content for XR entertainment inside the autonomous vehicle: a real external environment, a virtual simulation of the external environment, and a virtual live music venue. The Wilcoxon signed rank test with the Bonferroni correction after the Friedman test revealed that, without the moshing function, the virtual live music venue video significantly enhanced enjoyment and reduced anxiety, compared to the real one.conference pape

Plant stem cells: The source of plant vitality and persistent growth
Get PDFPlants have amazing vitality and persistence. Some tree species can live for thousands of years, and even when cut down, new sprouts emerge from the stump continuing their life. Similarly, if a horsetail is cut and fragmented, it is also capable of regenerating and flourishing from a remaining rhizome. Such features are based on the remarkable characteristics of plant stem cells. Plants are able to maintain pluripotency in stem cells generated during embryogenesis, and even after their differentiation, the cells can reprogram themselves and regenerate the whole plant body by acquiring pluripotency in response to stresses, such as wounding. Although humankind depends on the productive capacity of plants to meet various needs such as food, raw materials and maintenance of the global environment, we are yet to gain an understanding of the regulatory systems that generate their robust vitality. In other words, the elucidation of the molecular basis of plant vitality is one of the central issues not only in plant and agricultural sciences but also in life sciences. The history of stem cell study in plants is relatively young compared to that in animals. In plants, the dividing cell population containing stem cells is called a meristem and the maintenance and regulatory mechanisms of its activity have been studied. Nonetheless, our understanding of the intrinsic properties of plant stem cells had been somewhat limited due to difficulties in accessing these deeply embedded tissues. However, thanks to recent advances in molecular genetics and single cell technologies, it is now possible to study stem cell characteristics more deeply. This special issue explores the latest research into plant stem cells. The idea for this special issue was borne from a consortium research project ‘Principles of pluripotent stem cells underlying plant vitality’, which was conducted from 2017 to 2021 and supported by a Grant-in-Aid for Scientific Research on Innovative Areas from the Ministry of Education, Culture, Sports, Science and Technology, Japan. The project aimed to understand the characteristics of plant stem cells through a multifaceted approach to study the temporal and spatial control of stem cell proliferation and generation and the mechanisms underpinning the maintenance of pluripotency and genome homeostasis. The ultimate goal was to understand persistence and vitality characteristics of plants to enable sustainable organogenesis and regeneration, as also reflected in the pages of this special issue.journal articl

IVNPROTECT: Isolable and Traceable Lightweight CAN-Bus Kernel-Level Protection for Securing in-Vehicle Communication
Get PDFCyberattacks on In-Vehicle Networks (IVNs) are becoming the most urgent issue. The Controller Area Network (CAN), one of the IVNs, is a standard protocol for automotive networks. Many researchers have tackled the security issues of CAN, such as the vulnerability of Denial-of-Service (DoS) attacks and impersonation attacks. Though existing methods can prevent DoS attacks, they have problems in deployment cost, isolability of a compromised Electronic Control Unit (ECU), and traceability for the root cause of isolation. Thus, we tackle to prevent DoS attacks on CAN. To solve these problems of the existing methods, we propose an isolable and traceable CAN-bus kernel-level protection called IVNPROTECT. IVNPROTECT can be installed on an ECU, which has a wireless interface, just by the software updating because it is implemented in the CAN-bus kernel driver. We also confirm that our IVNPROTECT can mitigate two types of DoS attacks without distinguishing malicious/benign CAN identifie rs. After mitigating DoS attacks, IVNPROTECT isolates a compromised ECU with a security error state mechanism, which handles security errors in IVNPROTECT. And, we evaluate the traceability that an ECU with IVNPROTECT can report warning messages to the other ECUs on the bus even while being forced to send DoS attacks by an attacker. In addition, the overhead of IVNPROTECT is 9.049 $00B5s, so that IVNPROTECT can be installed on insecure ECUs with a slight side-effect.conference pape
