  • Energy-saving trajectory planning for robots using the genetic algorithm
           with assistant chromosomes
    • Abstract: Abstract Fossil fuel depletion and global warming are becoming increasingly important problems. Many trajectory plans for robot manipulators are developed by prioritizing operation efficiency, such as operating time and controllability, without considering energy consumption. In this study, the energy consumption problem is examined. This study discusses the application of a genetic algorithm (GA) to solve the problem of minimizing the energy consumption of a robot manipulator with nonlinear friction in the joints. The GA can search a wide area for an optimal solution; however, a long computation time is required. A gradient method can be used to quickly find a solution; however, the solution has a high probability of being a local optimum. This paper proposes a method that combines a gradient method and GA to quickly determine an optimal solution. In addition, the validity of the proposed method is examined.

  • Neural network-based construction of inverse kinematics model for serial
           redundant manipulators
    • Abstract: Abstract Solving the inverse kinematics of redundant manipulators is difficult, because knowledge of the manipulators and their evaluation functions is required. To solve this problem, we propose a novel method of enabling a neural network model to learn the inverse kinematics. The method achieves learning independent of the structure of the evaluation function, by combining multiple neural network models. The method can obtain the neural network models of the inverse kinematics via an automatic calculation process using only training data, which consist of the postures, end-points, and evaluation values. In this paper, the algorithm used by the method and its background is explained, and the effectiveness of the method is validated by a numerical simulation.

  • Obstacle avoidance path generation method for mobile robot using varying
           search range
    • Abstract: Abstract In this study, an obstacle avoidance algorithm, with variable range searching, is proposed for a mobile robot. In the case of the distance transform method, the mobile robot cannot avoid the obstacle when it is narrow. We prepare a grid map with the obstacle and distance levels from a destination. A path with both the least number of turns, and the shortest distance, is generated. The search range depends on the distance between the current position and the obstacle. The algorithm can generate the avoidance path without regard to the shape of the obstacle. In the computer simulation, the proposed algorithm can generate a path that avoids the obstacle. As an experiment, a position detection system used contrast differences, by means of a web camera, to get the coordinates of the mobile robot. It is confirmed that, in the experiment, the mobile robot reached the goal grids without hitting the obstacle.

  • Implementation of an AR Traditional Japanese Craft Presentation System:
           presentation of traditional crafts using the Kansei retrieval method
    • Abstract: Abstract The impressions of traditional Japanese crafts retrieved by a presentation system adopting the Kansei method were evaluated in a questionnaire survey. By analyzing the survey results, we associated the visual features of the traditional crafts with the Kansei words. Kansei means sensibility and the ability to accept the impression. In addition, we extracted a feature quantity of the traditional crafts, called the visual pattern image coding, from the traditional craft image, and associated this physical feature with the visual features of the traditional crafts. From these analyses, we implemented an augmented reality (AR) Traditional Japanese Craft Presentation System using the Kansei retrieval method. To evaluate the effectiveness of the Kansei retrieval method, we investigated the satisfaction levels of the retrieved results of traditional crafts. The subjects’ responses to the AR Traditional Japanese Craft Presentation System were overwhelmingly positive.

  • Effects of emotionally induced language sounds on brain activations for
    • Abstract: Abstract Emotions play an important role in human communication. We conducted a study to identify the effect of emotions in language sounds in terms of brain functions. The sounds of Japanese sentences spoken with and without emotion were reversed to eliminate their semantic influence on the subjects’ emotional perception. Three sets of sentences with non-emotional and happy, sad, and angry emotional tones were recorded and reversed. The brain activities of 20 native Japanese speakers in their twenties were monitored by near-infrared spectroscopy (NIRS) while they listened to the reversed Japanese sounds with and without the emotions. Our analysis of the experimental results demonstrated that almost all the brain areas monitored by the NIRS probes were activated more when the subjects listened to emotional language sounds than to non-emotional sounds. In particular, the frontopolar cortex area, which is associated with short-term memory, was significantly activated. Since short-term memory is known to provide important information for communication, these results suggest that emotional aspects of language sounds are essential for successful communication and thus should be implemented in human–robot communication systems.

  • Analysis of end-plate using multi-channel surface EMG
    • Abstract: Abstract By individually examining the characteristics of conducting waves in multi-channel surface electromyogram (EMG) signals, there is a possibility to understand the mobilization mechanism of muscle contraction. It is important to consider the potential obtained from the surface electromyogram (EMG) signal conducted from a large number of moving units in the muscle, as well as the interference potential due to the conducting action potential. The main purpose of this research paper is to find the exact characteristics of conducting waves close to an end-plate using the antiphase conduction method. To evaluate the position of the end-plate, every conducting wave will be investigated by multi-channel surface EMG, and the formation process for the conducting waves will be analyzed.

  • Emotional evaluation for pictures displayed with small FOV telescope
           environment in virtual reality headset
    • Abstract: Abstract We carried out an experiment to examine emotional effect associated with images displayed in small field of view (FOV) telescope like virtual screen environment with VR-HMDs. We manipulate FOV of a virtual camera in VR to change the view of contents. Decreasing FOV makes view of angle narrow, and therefore, the view in VR looks like telescope, in which environment the view greatly moves with even small HMD movement. With smaller value of FOV, the view in VR is more sensitive to HMD movement and requires subjects to keep concentrating not to move their heads to watch target contents properly. Stronger emotional responses were observed with smaller value of FOV in the experiment. The result indicates the possibility of controlling effectiveness of the same contents with the same VR-HMD. This result is expected to improve a wide range of medical usage of VR contents.

  • HMD-based cover test system for the diagnosis of ocular misalignment
    • Abstract: Abstract The diagnosis of ocular misalignment is difficult and needs examination by ophthalmologists and orthoptists. However, there are not enough qualified personnel to perform such diagnoses. The eye position check is in part systematized. With this check system, we can detect not only the symptoms but also the angle and the extent of strabismus. However, the types of strabismus that can be detected with this technique are limited to exotropia. The purpose of this study is to develop a simplified check system to screen at least the presence of strabismus apart from the type of strabismus or amount of ocular deviation. First, we digitalized the check process. Specifically, we digitized the elemental technology, i.e., the cover–uncover function, required for automation of the typical cover test for eye position check. Furthermore, we developed and implemented an abnormality determination process and evaluated the performance of the system through this experiment, the results of which indicated a higher detection capability than the conventional cover test performed by ophthalmologists and orthoptists.

  • Long-distance sea wave extraction method based on improved Otsu algorithm
    • Abstract: Abstract Sea wave extraction is the foundation of sea wave measurement, which plays a significant role in binocular stereo vision-based tsunami early-warning systems. However, long-distance sea surface images possess two typical features: ununiformed illuminance and a low signal-to-noise ratio that makes it difficult to extract sea waves out from sea surface images and that leads to incorrect extractions. In this paper, we improved the Otsu algorithm to realize a dynamic multi-threshold algorithm for sea wave extraction. First, the original image was divided into small blocks and the dynamic multi-thresholds were determined according to local sea surface illuminance. Then an evaluation function was defined to add constraint conditions to adjacent blocks’ thresholds. Finally, sea waves were extracted out using the blocks’ thresholds in all the blocks. As seen in our experimental results, the correct extraction rate was 80.9%, most sea waves are extracted regardless of their intensity.

  • Dynamic hybrid position/force control for the quadrotor with a
           multi-degree-of-freedom manipulator
    • Abstract: Abstract In the field of aerial robotics, physical interaction with the surrounding environment is currently receiving a considerable attention. One of the key challenges is to control not only the position, but also the force exerted by the end-effector while performing complex tasks such as object manipulation, inspection, and assembly/disassembly. To meet these demands, this paper proposes a dynamic hybrid position/force controller for a quadrotor-borne multi-degree-of-freedom manipulator. The system is modeled under the situation that the constraints on the end-effector are described by a set of hypersurfaces, and system dynamics are then developed while taking into account the redundancy of the system. To verify the effectiveness of the proposed hybrid controller, we carried out numerical simulations for two different application scenarios which include (1) placement of a sensor unit on a vertical wall and (2) inspection with contact on a curved-shape wall. The results show that the system is able to maintain the desired force and position simultaneously in both cases.

  • Use of access characteristics to distinguish legitimate user traffic from
           DDoS attack traffic
    • Abstract: Abstract Distributed denial of service attacks are a serious threat in the current information society, where the Internet plays an important role as infrastructure. We have been studying ways to mitigate these attacks using a method that distinguishes between legitimate users and attacks. Our previous method was not sufficient because it only analyzed access logs after the attack. In this study, we propose a new method that can distinguish between legitimate users and attacks while the services are running. When the IDS detects an attack, a quarantine server distinguishes legitimate users using access characteristics. The access characteristics are: (1) user follows links, (2) sender accessed a popular page, and (3) the sender’s current average transmission interval. Our experiments confirmed that the proposed method can distinguish between legitimate users and attacks.

  • Artificial intelligence, ethics and human values: the cases of military
           drones and companion robots
    • Abstract: Abstract Can artificial intelligence (AI) be more ethical than human intelligence' Can it respect human values better than a human' This article examines some issues raised by the AI with respect to ethics. The utilitarian approach can be a solution, especially the one that uses agent-based theory. We have chosen two extreme cases: combat drones, vectors of death, and life supporting companion robots. The ethics of AI and unmanned aerial vehicles (UAV) must be studied on the basis of military ethics and human values when fighting. Despite the fact that they are not programmed to hurt humans or harm their dignity, companion robots can potentially endanger their social, moral as well as their physical integrity. An important ethical condition is that companion robots help the nursing staff to take better care of patients while not replacing them.

  • An improvement of flight performance in the level flight of tilted
           quadrotors by attaching a fixed-wing
    • Abstract: Abstract Wide range information is required to be collected by unmanned aerial vehicles (UAVs) and the area for its take-off and landing is limited in the event of a disaster. Therefore, research on the development of a specific UAV, which has two functions of a long distance flight like a fixed-wing aircraft and of a hovering like a rotorcraft, is drawing attention recently. In this study, we focus on a hybrid tilted quadrotor, in which four rotors are tiltable and a wing is fixed. It is clarified, from a simulation comparison in a level flight mode, that the flight performance is effectively improved by adding a fixed-wing, where a tilted quadrotor is assumed to take a level flight by using a controller for a vertical-flight mode and by controlling the angles of some tiltable rotors. It is shown finally that adding a fixed-wing can save the rotor thrust about 77% per flight distance.

  • Practical problem-based programming learning using video
    • Abstract: Abstract The fundamental skills for information system development such as system designing, programming and project management are very similar to the fundamentals of general problem solving. In this paper, we proposed an education framework for practical problem solving based on system designing technologies and an application of proposed framework on video training materials to train the skills of modeling and understanding from ambiguous matter in practical problem via non-verbalized video training material. Our framework uses Resource Flow Diagram (RFD) to support the understanding of procedure and resources on problem solving. RFD is our proposed visualization method for procedure and resource management based on Sequence Diagram in Unified Modeling Language (UML). RFD is designed for the intuitive representation of the procedure flow and required resources since UML could not define them with single diagram. In this experiment, proposed education framework was applied for the understanding of cooking procedure from the cooking exhibition videos on the demonstrative lecture.

  • Implementation of a historical materials’ presentation AR system in
           cooperation with a cable television program
    • Abstract: Abstract In cooperation with a cable television program, we constructed an augmented reality (AR) system for the presentation of historical materials. We proposed a new media-fusion system called the historical materials’ presentation AR system, which integrates digital archives, AR technologies, and television programs. The proposed system consists of a mobile application and an AR-contents’ management system. The mobile application provides the user with historical museum materials in the form of AR contents and voice guidance. This application consists of the top screen, the AR-content acquisition screen, and the map screen. Meanwhile, the AR-content management system manages the AR contents and voice guidance provided to the user. This management system is a data management Web application for registering, editing, and deleting AR contents and the voice guidance used in the mobile application. The operability, necessity, and functionality of the historical materials’ presentation AR system were evaluated in a questionnaire survey of 45 subjects. All items were highly rated by the respondents.

  • Multi-objective safe reinforcement learning: the relationship between
           multi-objective reinforcement learning and safe reinforcement learning
    • Abstract: Abstract Reinforcement learning (RL) is a learning method that learns actions based on trial and error. Recently, multi-objective reinforcement learning (MORL) and safe reinforcement learning (SafeRL) have been studied. The objective of conventional RL is to maximize the expected rewards; however, this may cause a fatal state because safety is not considered. Therefore, RL methods that consider safety during or after learning have been proposed. SafeRL is similar to MORL because it considers two objectives, i.e., maximizing expected rewards and satisfying safety constraints. However, to the best of our knowledge, no study has investigated the relationship between MORL and SafeRL to demonstrate that the SafeRL method can be applied to MORL tasks. This paper combines MORL with SafeRL and proposes a method for Multi-Objective SafeRL (MOSafeRL). We applied the proposed method to resource gathering task, which is a standard task used in MORL test cases.

  • Turtle graphics for early Java programming education
    • Abstract: Abstract Turtle graphics, first introduced in the Logo programming language in the late 1960s, have since been widely used in programming education. Turtle graphics is excellent for programming training, providing an intuitive platform for understanding the fundamental procedural programming principles, through its simple graphics functions allowing visual feedback for programming. This paper introduces a new and original application of turtle graphics to Java programming language, particularly targeted to early Java programming education. The aim of the proposed Java language turtle graphics library is (a) to use turtle graphics to provide intuitive understanding of fundamental procedural programming principles, (b) to provide an easy tool for the students to create visually interesting programs in the early stages of programming education, and (c) to stimulate the motivation of students to improve the learning effect of programming training and encourage further self-study. The proposed Java language turtle graphics library was introduced to 1st year college students with minimal Java language programming training, to verify the effectiveness of the proposed method.

  • Advanced eye-gaze input system with two types of voluntary blinks
    • Abstract: Abstract Recently, several eye-gaze input systems have been developed. Some of these systems consider the eye-blinking action to be additional input information. A main purpose of eye-gaze input systems is to serve as a communication aid for the severely disabled. The input system, which employs eye blinks as command inputs, needs to identify voluntary (conscious) blinks. In the past, we developed an eye-gaze input system for the creation of Japanese text. Our previous system employed an indicator selection method for command inputs. This system was able to identify two types of voluntary blinks. These two types of voluntary blinks work as functions governing indicator selection and error correction, respectively. In the evaluation experiment of the previous system, errors were occasionally observed in the estimation of the number of indicators at which the user was gazing. In this study, we propose a new input system that employs a selection method based on a novel indicator estimation algorithm. We conducted an experiment to evaluate the performance of Japanese text creation using our new input system. This study reports that using our new input system improves the speed of text input. In addition, we demonstrate a comparison of the various related eye-gaze input systems.

  • DEA cone ratio model based on a paired comparison
    • Abstract: Abstract Data Envelopment Analysis (DEA) is well known as evaluation method to measure the efficiencies of decision making units (DMUs) relatively with multiple inputs and outputs items. One of the features of DEA is that DMUs are evaluated based on the Pareto optimal line composed of efficient DMUs (this line is called as “Efficiency Frontier” in DEA). As the efficiency value of the target DMU is calculated by the relative comparison between the current DMU and the point on the efficiency frontier which is the easiest to achieve, the compared points differ for every DMU. Therefore, it is possible to evaluate the efficiency of DMUs relatively considering features of them. On the other hand, there are many cases that a certain adjustment about the data is necessary to make some decisions from the objective results of DEA. To analyze the DEA results continuously, this paper proposed the DEA framework. A proposed framework consists of two following steps: (1) extracting subjectivity information based on a paired comparison, (2) extending the traditional DEA model. The proposed model does not add restrictions to a variable directly and it is formulated in the form where it corrects the search direction, “No solution” does not come out of it. Since the proposed model is correcting the search direction, an analyst’s intention is incorporated without taking out an execution impossible solution.

  • Uncertainty of the second order
    • Abstract: Abstract We study the stochastic dynamics of the quasispecies model with inverse Bayesian inference under environmental uncertainty. Inverse Bayesian inference is introduced through the correspondence between Bayesian inference and the replicator equation. We consider environmental uncertainty that is not modeled as the stochastic fitness called uncertainty of the second order. This is in contrast to uncertainty of the first order that can be subsumed by the stochastic fitness. The difference between these two kinds of uncertainty is discussed in the framework of categorical Bayesian probability theory. We analytically show that if the time scale of inverse Bayesian inference is sufficiently larger than that of Bayesian inference, then the quasispecies model exhibits a noise-induced transition. The theoretical result is verified by a numerical simulation.
