To maintain skin moisture, we need to maintain good stratum corneum barrier function, which prevents moisture evaporation from the inside of the skin. Transepidermal water loss (TEWL), the amount of water that evaporates from the skin, indicates the state of barrier function. The barrier function of facial skin is easily damaged in daily life, and...

Subjectivity has been an inherent issue in the conventional Fugl-Meyer assessment, which has been the focus of impairment-level recognition in several studies. This study continues our previous work on the use of EMG to recognize finger movement impairment levels. In contrast to our previous work, this study provided a better and more reliable reco...

Subjectivity has been an inherent issue in the conventional Fugl-Meyer assessment, which has been the focus of recognition research in several studies. This paper continues our previous work on a recognition method of finger movement impairment levels using EMG. In contrast to our previous work, this paper provided a better recognition result with...

Anterior cruciate ligament (ACL) injuries are common in sports involving jumping and rapid direction changes, often occurring in non-contact situations. The risk of ACL injury is evaluated by knee flexion and valgus angles; a small knee flexion angle combined with a large valgus angle increases the risk. Monitoring these angles during activities ca...

Storytelling is one of the most important learning activities for children since reading aloud from a picture book stimulates children’s curiosity, emotional development, and imagination. For effective education, the procedures for storytelling activities need to be improved according to the children’s level of curiosity. However, young children ar...

Programming is becoming a new literacy, and programming education is being implemented in various settings. One of the issues faced by novice programmers is a lack of problem-solving skills. They have difficulty planning abstract solutions in the program and expressing solutions as a program. This study proposes a programming learning system that s...
Chapter
The knee is the most common site for running injuries. Fatigue causes changes in the knee angle at landing, which increases the impact acceleration at landing and leads to injury. To prevent such injuries, this paper proposes a wearable system that acquires knee bends and estimates the knee angle in real-time during running using a supporter-shaped...
Chapter
Human eyes maintain visual function by adapting to changes in brightness. There are two types of adaptation to changes in brightness. Light and dark adaptations occur when the surroundings become bright and dark, respectively. Human eyes cannot adapt immediately when brightness changes rapidly. Therefore, a decline in visual function and accidents...

Getting stuck is an inevitable part of learning programming. Long-term stuck decreases the learner’s motivation and learning efficiency. The current approach to supporting learning in lectures involves teachers finding students who are getting stuck, reviewing their source code, and solving the problems. However, it is difficult for teachers to gra...

Due to COVID-19, various lecture styles are being explored. On-demand lectures are attracting increasing attention due to advantages such as being able to watch without restrictions due to location and time. In contrast, on-demand lectures have disadvantages, such as no interaction with the lecturer, so the quality of on-demand lectures should be i...
Chapter
Various stumbles occur when learning programming, which leads to lower learning efficiency and motivation. If such stumbles could be detected automatically, teachers could monitor learners’ progress and support passive students. Stumbles in learning programming can be classified into several types, which could be divided into those that are evident...

With the popularization of head-mounted displays (HMDs), many systems for human augmentation have been developed. This will increase the opportunities to use such systems in daily life. Therefore, the user interfaces for these systems must be designed to be intuitive and highly responsive. This paper proposes an intuitive input method that uses nat...
Chapter
In this study, using sensors, we analyzed the movements of Japan’s top-level boccia athletes, which is one of the official Paralympic sports. Motion analysis in sports has been widely studied, and a gradual approach is commonly available to help amateurs improve their skills. However, in two specific cases, personal observations are necessary. One...

With the spread of smartphones, mothers who operate smartphones while breast-feeding are increasing. This kind of activities are sometimes defined as a bad behavior although this is one of few repose in parenting. In this paper, we investigate if the use of smartphone affects the breast-feeding from the viewpoints of the mother's posture and the qu...
Article
We propose a system that structures a meeting log by detecting and tagging the partici- pants’ actions in the meeting using acceleration sensors. The proposed system detects head movement such as nodding of each participant or motion during utterances by using ac- celeration sensors attached to the heads of all participants in a meeting. As an eval...

In this paper, we propose a method for recognizing postures and gestures by using foot pressure sensors, and we investigate optimal positions for pressure sensors on soles from the viewpoint of motion recognition accuracy. In experiments, the recognition accuracies of 22 kinds of daily postures and gestures were evaluated from foot-pressure sensor...

This paper proposes a method for recognizing postures and gestures using foot pressure sensors, and we investigate optimal positions for pressure sensors on soles are the best for motion recognition. In experiments, the recognition accuracies of 22 kinds of daily postures and gestures were evaluated from foot-pressure sensor values. Furthermore, th...

Learning activities were evaluated using questionnaire survey, video, or audio. However, these methods have the following problems. First, writing on the questionnaire paper is difficult, especially for little children. Second, because the answering questionnaires was performed after the experiments were finished. They were different temporally and...
