Thanks to the latest sensing technology and smart devices, many researchers have focused on sports-skill analysis. Electromyography (EMG), in particular, is gaining attention as a method of understanding the power-generating process in motions. However, most existing applications using EMG have remained being one-time measurement. This is because athletes do not know how to use the results and how to measure their improvement. We propose a sports-skill-training framework with muscle-usage indicators based on EMG and an EMG live visualization system. With this framework, athletes can determine the skill they need to improve by focusing on skills whose indicators are poor, activate their muscles with live feedback to overcome weaknesses, and quantitatively measure their improvement as the improvement of the indicators during the activation training. We also verified the effect of coaching in this framework on cycling athletes. The experimental results quantitatively indicate the effectiveness of continuous skill training with our framework.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115524575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underlying textile has its own anisotropic mechanical behaviors due to its woven or knit fabrication process, and introduces non-trivial structural influences on integrated wearable strain sensors. This study considers stitched strain sensors of two stitch geometries, fabricated on two different knit fabrics, with the sensor stitched in different orientations with respect to the knit structure. The resulting mechanical and electrical performance is characterized under cyclic extension, as the angle of extension (relative to the fabric) is also incrementally changed. The results illustrate a shift from linear to non-linear mechanical behavior as fabric stiffness increases, and variations in behavior between stitch geometries. Results show that force direction and sensor placement both introduce variability in calculated elastic modulus, which affect sensor modeling (e.g. predicting applied force from sensor response). A novel stitch geometry (the chainstitch sensor) is characterized as having a higher gauge force and lower transverse sensitivity factor than the coverstitch sensor. This work offers insight into the textile-sensor interface and design implications for development of textile-based sensors.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129634431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sugimoto","doi":"10.1145/3341163.3347747","DOIUrl":"https://doi.org/10.1145/3341163.3347747","url":null,"abstract":"In this study, we propose a new input method for mobile and wearable computing using facial expressions. Facial muscle movements induce physical deformation in the ear canal. Our system utilizes such characteristics and estimates facial expressions using the ear canal transfer function (ECTF). Herein, a user puts on earphones with an equipped microphone that can record an internal sound of the ear canal. The system transmits ultrasonic band-limited swept sine signals and acquires the ECTF by analyzing the response. An important novelty feature of our method is that it is easy to incorporate into a product because the speaker and the microphone are equipped with many hearables, which is technically advanced electronic in-ear-device designed for multiple purposes. We investigated the performance of our proposed method for 21 facial expressions with 11 participants. Moreover, we proposed a signal correction method that reduces positional errors caused by attaching/detaching the device. The evaluation results confirmed that the f-score was 40.2% for the uncorrected signal method and 62.5% for the corrected signal method. We also investigated the practical performance of six facial expressions and confirmed that the f-score was 74.4% for the uncorrected signal method and 90.0% for the corrected signal method. We found the ECTF can be used for recognizing facial expressions with high accuracy equivalent to other related work.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115729533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
