    In this work, we have incorporated an electronic travel aid (ETA) as a smartphone application that alerts fall risks to the visually impaired. The application detects negative obstacles, such as platform edges and stairs, and occlusion using a grid map including height information to estimate fall risk based on the distance from an area’s edge to the user, and the area ratio. Here, we describe a grid map correction method based on the surrounding conditions of each cell to avoid area misclassification. The smartphone application incorporating this correction method was verified in environments similar to station platforms by evaluating its usefulness, robustness against environmental changes, and stability as a smartphone application. The verification results showed that the correction method is, in fact, useful in actual environments and can be implemented as a smartphone application.

    We have developed a fall risk alert system using a smartphone with a LiDAR sensor, Apple’s iPhone 12 Pro, as an electronic travel aid (ETA) for visually impaired to reduce fall risks from the edge of station platform and the stairs. The proposed system generates the height grid map generated from 3D point clouds and posture from the smartphone, and classify the walking area to four areas, walkable, positive obstacle, negative obstacle and occlusion areas. In this paper, we describe the algorithm and the experimental results of the environmental recognition system for the fall risk alert. In the experiments, the accuracy, stability, and time delay are evaluat-ed in approaching a fall risk area, such as stairs. The results show the smartphone has the possibility to be the ETA to support the visually impaired and reduce the fall risks.

    We have developed the fall risk notification system using LiDAR sensors to reduce number of fall accidents on platform involving visually impaired people. In this paper, we report the experiment results of the environment recognition algorithm for the fall risk notification system. In this algorithm, height grid map is generated from the depth image from LiDAR sensor and the posture of iPhone. In the experiment, we evaluated the accuracy and responsivity when approaching risky area of falling, such as stairs.

    The number of robots exiting in human living spaces has increased, and interaction between humans and robots has become an important issue. The purpose of this study is to propose a future society where humans, animals, and robots coexist. We organize relay race, or ekiden in Japanese, where they compete together as runners. The competition rules have been established to ensure that each runner can compete fairly. This paper explains the competition rules and discuss the fairness of the rules

    In this paper, in order to evaluate the plane detection algorithm for detecting the edge of a station platform, we verified the algorithm by running it on the 3D distance data measured at the actual station platform. As the result, we were able to detect the plane with the error that is small enough to distinguish it from steps such as stairs. However, the correct answer rate and the true negative rate were greatly reduced by the distant point clouds and the movement of the sensor itself, so it is necessary to remove the distant point clouds and to reduce the error caused by the movement of the sensor itself in the current algorithm. In the future, we will verify the algorithm in other situations, and implement and verify additional processing.

    In this study, in order to develop the electronic travel aid for the visually impaired to reduce the number of falling accidents, we studied the concept of the aid to be developed based on the problems to be solved by the aid and the problems in the previous devices. In addition, for the environmental recognition part of the device, we examined 3D distance measurement using RGB-D sensors, and for the information presentation part, we analyzed the vibration generated in the cane itself that causes confusion of information during use with the device. In 3D distance measurement, the disturbance of the depth image generated when the cane is shaken was confirmed. From analysis the vibration generated in the cane itself, the possibility that the effect of the unevenness of the road surface becomes large in the frequency range of 0 to 100[Hz] was shown. In the future, we will study the algorithms and presentation patterns in detail based on the experimental results.

    This paper presents the information presentation device for alerting 4 dangerous situations on a platform by vibration stimulation of a local position. The vibrator mounted on the information presentation device is provided with vibration isolation to prevent confusion of the presented information. In order to confirm the occurrence of the vibration stimulus at the local position, the measurement experiment of the vibration acceleration was carried out using the acceleration sensor. From the result of power spectrum analysis using the fast Fourier transformation to the measured vibration acceleration, periodic damping was confirmed at a portion other than the vibrator that presents information.
