However, such large projection systems are frequently based on large implementation and high-cost components like a special projector and screen. This situation limits users receiving the benefits with those technologies. Therefore, in this paper, we propose an effective immersive projection system using simple projectors and convex mirrors for our everyday surfaces like a wall in a room. We also introduce a simple calibration method for making that system easy to use for many people.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133681086","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}

Therefore, there are many researches to prevent and detect drowsy driving. Recent researches have focused on motion detection using cameras to determine drowsy driving. However, we have focused on non-invasive and inexpensive drowsiness detection system. In our previous research, we suggested a system based on the driver's head movement using infrared sensors. In this paper, we suggest another non-invasive and inexpensive system based on the driver's pulse wave by photoplethysmography (PPG) signal processing. Firstly, the system collects a pulse wave from a PPG sensor on a steering wheel and then it processes the signal to analyze driver's state. In order to evaluate the effectiveness of a human pulse wave for drowsiness detection, we integrated two systems. The experimental result using new integration system showed 83 percent drowsy driving detection rate in the state of real driving.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122737166","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}

We believe that there exits a positive correlation between the accuracy of sentences translated to an intermediate language and that of back-translated sentences. However, this has not yet been verified. However, some back-translated sentences have high accuracy even if the translated sentence is inaccurate. Therefore, we have to verify the correlation between the accuracy of sentences translated to an intermediate language and that of back-translated sentences. We have evaluated the accuracy of back-translated sentences and that of sentences translated to an intermediate language to establish the correlation between the two accuracies. We have obtained the following results: (1) There exists a positive correlation between the accuracy of sentences translated to an intermediate language and that of back-translated sentences. (2) The occurrence rate of an accuracy mismatch case, wherein a back-translated sentence is accurate but the translated sentence is inaccurate, is less than or equal to 0.5%. (3) Back-translation can be used to check the accuracy of a translated sentence.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"11 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127158171","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 model uses latent semantic indexing to detect underlying semantic relationships within documents. Each document is interpreted as a generative topic model belonging to many topics. The relevance of a document to a query is expressed by the probability of a query being generated by the model. The term-document matrix used for NMF is built stochastically from the speech recognition N-best results, so that multiple recognition hypotheses can be utilized to compensate for the word recognition errors. Using this approach, experiments are conducted on a test collection from the Corpus of Spontaneous Japanese (CSJ), with 39 queries for over 600 hours of spontaneous Japanese speech. The retrieval performance of this model is proved to be superior to the conventional vector space model (VSM) when the dimension or topic number exceeds a certain threshold. Moreover, whether from the viewpoint of retrieval performance or the ability of topic expression, the NMF-based topic model is verified to surpass another latent indexing method that is based on the singular value decomposition (SVD). The extent to which this topic model can resist speech recognition error, which is a special problem of spoken document retrieval, is also investigated.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115294524","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}

We employ the semantic equivalence classes of a recently compiled large scale hierarchical lexicon of Japanese functional expressions. We examine each class whether it is monosemous or not. We realize this procedure by empirically studying whether functional expressions within a class can be translated into a single canonical English expression. Furthermore, in order to precisely identify the class of functional expressions to which our translation rule is directly applicable, we further introduce two types of ambiguities of functional expressions and identify monosemous functional expressions. We finally show that the proposed framework outperforms commercial machine translation software products.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132937796","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}
