© 2020, Springer Nature Switzerland AG. The purpose of this study is to assist the visually impaired to develop applications. There is a method for the visually impaired to develop applications by reading program codes with screen reader. In this method, the visually impaired can read code on line by line and select a line by knocking the up and down arrow key on the keyboard. After that, they can read the processing and describe an instruction before and after the processing. However, such an operation takes them a long time. Therefore, we suggested the system which let develop applications by editing flowcharts. This system converts program code into flowchart and read blocks in the flowchart. In this system, they can select blocks by knocking the left, right, up and down arrow key. We compared the time for rewriting programs between approach and the proposed system. As a result, the time reduced in all programs.

© 2020, Springer Nature Switzerland AG. When the visually impaired people go out alone, they rely on white canes and Braille blocks. However, there are problems on the route, such as obstacles on the sidewalk Braille blocks. As a result, a traffic accident or a fall accident from the station’s platform has occurred. That is the cause many cases where people go out without worrying about troubles. In this research and development, those obstacles are detected using a stereo camera linked to a smartphone, and the content is guided to the user by a wearable speaker. In addition, the location of the user is captured by GPS and guided to the destination. There are two stages, one for “Mobility Support Service” and “Watch Over Service”.

© 2019 Association for Computing Machinery. In this paper, the horizontal sound image experiment of the real sound source was performed under the head resting condition using the band - limited noise using the low pass filter and the band pass filter. Then, the effect of each frequency band on direction perception of the hearing person and the elderly person was clarified. Five people with healthy men in their twenties and five elderly people in their 70s male hearing white noise pass through low-pass filters (2, 3, 4, 5, 6 kHz) and band-pass filters (1-4, 2-4, 2-5 [kHz]) passed through the directional perception experiment. As a result, similarly to the previous study [1], it is difficult to perceive directions sufficiently if two or more frequency bands are included, and it is difficult to perceive the direction of band-pass noise through a band-pass filter of a narrow frequency band. As a result of this research, Direction perception was found that the frequency band around 4 [kHz] and 6 [kHz] is small as an element of direction perception and the frequency band around 5 [kHz] is an important clue for direction perception.

© 2019 Association for Computing Machinery. In recent years, malicious visit sales are increasing in Japan, targeting elderly people living alone and dementia patients. Since it is difficult for them to deal with problems with their own power, it is necessary for surrounding people to support damage deterrence. So, we aim to realize a watching system that anyone can use if there is only a smart speaker. In this study, we propose a method to detect door-to-door sales from conversation information of elderly people and visitors with the aim of realizing a system to prevent elderly consumers' troubles. In the evaluation experiment, we evaluate how accurately door-to-door sales can be detected out of the conversation dataset. In addition, we try to determine the risk degree by learning the door-to-door sales sample data given the risk label.

© 2019 Association for Computing Machinery. In Japan, accidents are occurring when visually impaired people go out. For example, a collision with an obstacle such as a person or a wall, or a fall from the station platform. A current measure for this problem is a voice guidance. However, visually impaired people place importance on auditory information. Therefore, it is difficult for them to hear surrounding sounds during listening the voice guidance. There is a previous research that trying to guide the visually impaired people to their destination by vibration transmission. However, although this study have realized the guidance of the visually impaired people to their destination without interrupting environmental sounds, this method cannot correct the veering in real time. For above reason, we propose a veering correction system by vibration transmission, which does not disturb acquisition of auditory information. This is a system that gives them vibration by wearing a vibration motor on their shoulders and corrects the veering. In this article, we conducted verification experiment of the effectiveness of the veering correction by vibration transmission as a preliminary study in the development of the veering correction system. As a result of the research, we were able to keep the deviations from over 100 cm to less than 100 cm. As a conclusion, vibration transmission is effective as a method of correcting the veering of visually impaired people.

© 2019 Association for Computing Machinery. In recent years, the damage caused by the earthquake has become very large in Japan. Secondary disasters such as tsunami and fire are the main causes of death due to the earthquake, both of which are causes of evacuation delay. Rapid evacuation is important in the event of a disaster. However, due to the earthquake, various obstacles will occur in the aisle. Obstacles may occur due to the collapse of houses due to the earthquake and it may take time to pass. If you can obtain information about the aisle in advance and avoid evacuation routes in advance, you can complete evacuation safer and more quickly. As a method of acquiring traffic information, We thought that the use of SNS is useful from the viewpoint of the real-time nature of information and the penetration rate of young people aggressively actively communicating information. In this research, we proposed an evacuation guidance system to evacuate users with a safe shortest route. Then we examined the danger of passing through obstacles. As a result, "road shredder" is evaluated as the most dangerous, and "road crack" is evaluated as the most secure.

© 2019 Association for Computing Machinery. ACM In recent years, the demand for the logistics industry has increased enormously due to the spread of Internet mail order. On the other hand, the number of fatal accidents caused by trucks is more than 10,000 a year in Japan. Above all, there is a problem that there is an annual fatal and fatal accident due to truck load collapse. In this study, using the drive recorder, we calculated the inclination of the package photographed during driving by using KCF of object tracking method of image processing. Comparing the change of the Luggage tilt and the amount of change in 3-axis acceleration attached to the vehicle/ time of each frame in all the data, frames at each maximum value point almost agreed at the time of” When riding over convex part of inclined road”. On the other hand, “When a sudden steering wheel during driving”, a point where the absolute value of the change in package inclination during one frame reaches 0.005 ° and the point where the maximum change occurs after that. It almost coincided with the point where the curve was reached in the video. As for the 3-axis acceleration sensor, there is no difference in tendency between the curve and the straight running, and it is considered as the main cause that the influence of the roughness of the road is greatly influenced rather than the influence at the time of the curve.

© 2019 Association for Computing Machinery. In the train while driving, there are many noises such as noises from the vibration of the vehicle and the shock noise generated at the vehicle connection, and the roar of human beings, etc. In addition to stressing the passengers, these noises it prevents you from listening to the announcements in the train. In this paper, a new noise canceling earphone system aimed at improving in-car announcement speech listening and reducing stress that the noise gives to passengers by separating surrounding speech and in-train announcement speech regarded as noise I devised. In this study, as a preliminary step to complete the system, in order to find the difference between the ambient speech and the announcement speech such as the roar of the passenger, both speeches were compared using acoustic features. As a result, among the acoustic features used in the comparison, differences were found in the spectral centroid, the spectral roll-off, and the intensity and spectral contrast when divided into sub-bands.

Enhancement of electrolarynx speech based on WaveRNN 査読有り

Urabe E., Hirakawa R., Kawano H., Nakashi K., Nakatoh Y.

ACM International Conference Proceeding Series 2019年05月

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）

© 2019 Association for Computing Machinery.ACM In Japan, there are about 30,000 people whose larynxes have been removed. These people are not able to make voice, so they have problems in communication. For example, they cannot communicate their will enough with communication by writing or gestures alone, thereby avoiding communication. However, they can move the mouth and tongue normally. Therefore, they speak using alternative vocalizations. Electrical artificial larynx (EL) is one of the alternative vocalizations. When the vibrator is pressed against the lower part of the jaw, the vibration sound is transmitted in the sound path. This speech method is easy to learn and is cleaner than other speech methods, but this voice sound is bad quality because it has no intonation and it is noisy. In this study, we tried to improve the EL sound quality by using WaveRNN that is one of Deep learning. After making WaveRNN learn human voice, we converted the EL voice. We evaluated the converted voice in a subjective evaluation experiment in 10 words that selected each consonant and vowels in a balanced manner. The evaluation items are: 1. Clarity of consonants, 2. Clarity of vowels, 3. Clarity of whole voice, 4. Natural, 5. Easy to hear. As a result, Clarity and naturalness of consonants improved in words containing two or more unvoiced consonants. On the other hand, in the voiced consonants and vowels, no improvement was seen by the proposed method. Therefore, we think that voice quality was improved in unvoiced consonants. On the other hand, there was no tendency for improvement in voiced consonants and vowels.

This study aimed to evaluate the effectiveness of an exercise on the people with autism spectrum disorder using the NeuCube spiking neural network (SNN) architecture. We collected EEG patterns during perception and imitation of facial expressions for each emotion. Comparing the collected data in perceiving and mimicking facial expressions, EEG patterns of typically developed person were very similar. This fact suggest that it seems that there are mirror neurons on facial expression in the human brain. Recently, some studies have been reported that mirror neuron system does not work well in the case of subjects with brain disorders. In this paper, we observed mirror neurons during normal perception and imitation of facial expressions in typically developed subjects (TP), ASD subjects who exercise regularly (ASDe), and ASD subjects who don't exercise regularly (ASDn). As a result of experiments, we confirmed the mirror neuron activities of ASDe subjects tend to be close to ones of TP subjects compared to ones of ASDn subjects. The results in the experiments imply the effects of regular exercise on autism spectrum disorder.

© 2018, Springer International Publishing AG, part of Springer Nature. Spatio/Spector-Temporal Data (SSTD) analyzing is a challenging task, as temporal features may manifest complex interactions that may also change over time. Making use of suitable models that can capture the “hidden” interactions and interrelationship among multivariate data, is vital in SSTD investigation. This chapter describes a number of prominent applications built using the Kasabov’s NeuCube-based Spiking Neural Network (SNN) architecture for mapping, learning, visualization, classification/regression and better understanding and interpretation of SSTD.

In recent years, the number of patients with chronic kidney disease in Japan has reached 13.3 million (1 in 8 of adults over 20 years old). The disease is said to be a new country illness. The important factors of the chronic kidney disease have been clarified by long-term clinical studies. In this paper, we propose a new methodology to discover important factors inherent to the chronic kidney disease patients consisted by Topological data analysis (TDA) and Layer-wise Relevance Propagation (LRP). To verify the effectiveness of the proposed method, we compared the result obtained by our proposed method with the known important factors by the clinical studies.
