Furthermore the mobile-phone is so well spread that almost everyone owns a mobile-phone because of its simplicity. Many people carry their mobile phone anywhere with them. We can say that a mobile-phone becomes a commodity for everyone. The purpose of this paper is to propose a mobile - learning support system using LT/R ·W method. LT/R ·W method is one of techniques for getting learning diagnosis information from each answer in multiple-choice test. Using LT/R ·W method we are able to grasp the learner's understanding state not only from judging if the answer is right or wrong but also from a relationship between the level of difficulty of each question and the level of understanding of each learner. And also we are able to grasp from a relationship between the amount of time that a particular learner takes to solve each question and the amount of time to do so in general. We design the learning support system using LT/R ·W method and implement it as an “i-application (for NTT docomo's mobile phone)”. Moreover we carry out the evaluation of the system through a questionnaire to users.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114606158","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 use of navigation and communication platform will be an integral part of on board unit (OBU). Applications on OBU have been growing substantially in recent years to reduce the probability of accidents. On navigation and locating part, locating solution innovation is now driven by requirements of location based services on logistics. The fact is mass users distributing in urban canyons, indoors or in shaded areas where Global Navigation Satellite Systems (GNSS) signals can be attenuated, so the navigation platform generally need be supported by combining GNSS with wireless network and wireless sensor network. On communication part, it is necessary to establish a vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication unit beyond the consideration of the road safety. In this paper, the architecture of OBU which have an advanced navigation and communication plat are presented first. Then the fundamental location estimation combined with GNSS, 3G wireless networks and WSN is developed. Finally, the OBU semi-physical Simulation platform is developed. Navigation and communication platform in OBU for safety services is demonstrated in this paper with its seamless integration feature.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121986029","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 Canny algorithm optimizes the edge detection through noise filtering using an optimal function approximated by the first derivative of a Gaussian. It identifies the edge points by computing the gradients of light intensity function based on the fact that the edge points likely appear where the gradient magnitudes are large. Hexagonal structure is an image structure alternative to traditional square image structure. Because all the existing hardware for capturing image and for displaying image are produced based on square structure, an approach that uses linear interpolation described for conversion between square and hexagonal structures. Gaussian filtering together with gradient computation is performed on the hexagonal structure. The pixel edge strengths on the square structure are then estimated before the thresholds of Canny algorithm are applied to determine the final edge map. The experimental results show the edge detection on hexagonal structure using static and video images, and the comparison with the results using Canny algorithm on square structure.","PeriodicalId":284323,"journal":{"name":"2009 Joint Conferences on Pervasive Computing (JCPC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115987636","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}
