Considering the electromyography (EMG), which measures electrical potentials generated by muscle contractions from human body, would reflect the muscle activities during human locomotion, this kind of biomedical signal can be utilized to capture human walking characteristics in PDR. The work presented in this paper is the consecutive step of our pilot studies in further developing a novel and robust PDR solution using wearable EMG sensors to measure walking steps. Our PDR solution includes the EMG-based activity classification, step occurrence detection, and step length estimation, as well as the position calculation with the heading from a two-axis digital compass. To avoid step misdetection, two kinds of activities: walking normally and standing still, are classified via the hidden Markov model classifier fed by the sample entropy features extracted from the raw EMG data. Some EMG statistical parameters are also investigated to establish the optimized step length model. To validate the feasibility and effectiveness of this method, several field tests were conducted by a male tester in two experimental sessions, to demonstrate the effectiveness and practicability of the method using EMG to measure walking steps. Furthermore, the results indicate the performance of the PDR solution is comparable to that of the GPS under open-sky environments.","PeriodicalId":373653,"journal":{"name":"2010 Ubiquitous Positioning Indoor Navigation and Location Based Service","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123018391","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}

Information visualization techniques are invaluable tools in numerous applications. The goal of this work is to provide visual access to GPS information through the proposed trip planning web application. The main focus is on visualization, organization, fast retrieval, and effective understanding of GPS data mainly for public use, and the simplest way to plan the journey through the city. The main objective is to introduce this internet-based application to the users of the public transport services. The GPS technology is a new technology in Macedonia and trip planning is not implemented yet, although it has been used in many countries remarkably within the last years. Combining the collected GPS and timetable data in order to bring passengers to a desired location, the goal of journey planner is to reduce travel related risks and uncertainties for passengers who want to travel to an unknown part of the city, or tourists, elderly people or people who usually do not use public transport service.","PeriodicalId":373653,"journal":{"name":"2010 Ubiquitous Positioning Indoor Navigation and Location Based Service","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116809383","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}
