The main application could be the supervision of smart hospital-rooms, where the different crying patients (speaking patients) are localized thanks to their voice features inside the hospital. The proposed method uses the information given by the microphones, placed in different positions, in order to determine the position of the active speaker (person/patient who is crying) and try to supervise the audio-visual recording (eg. supervision of smart-rooms). The speaker identification approach is based on Second Order Statistical Measures (SOSM), which employs the vocal characteristics of the speaker (Mel Frequency Spectral Coefficients). Experiments are conducted on several scenarios containing one, two or three speakers in the smart-room. Results show that the proposed approach is interesting and easy to implement.","PeriodicalId":188977,"journal":{"name":"Fourth International Conference on Information and Communication Technology and Accessibility (ICTA)","volume":"27 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120816406","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}

Several studies have been carried out concerning personalization to provide a personalized environment when using a learning management system. However, these systems cannot be adapted to all kind of learners regardless of the degree of customization. Questions arise: Can the learner compose his own curriculum? Can he set his personal learning objectives? Can he take autonomously control of his learning? In this situation the concept of personalized learning environment is not enough, but rather the concept of personal learning environment that currently growing interest.","PeriodicalId":188977,"journal":{"name":"Fourth International Conference on Information and Communication Technology and Accessibility (ICTA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121848474","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}

However, it still remains a difficult task to establish. Generally, evaluators exploit a single method to proceed to an interactive system evaluation. However, many authors assert that a single method is not enough to obtain relevant evaluation results. As a solution, we propose a decision-making approach for the synthesis of data collected by different evaluation methods to obtain more reliable evaluation results. The proposed approach is based on three evaluation methods: the questionnaire, the ergonomic quality inspection and the electronic informer. As an evaluation result, the proposed approach provides evaluators with the quantification of the evaluation dimensions: the usability and the system functionality degree.","PeriodicalId":188977,"journal":{"name":"Fourth International Conference on Information and Communication Technology and Accessibility (ICTA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132835518","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}

Although, this problem can be solved by developing a new transcription system based on one of existing annotation like gloss. In this context, we present a new transcription system for the American Sign Language (ASL) based on gloss annotation system. Initially, a descriptive study of glosses will be detailed to clarify the transcription system. In a second step, we describe our system following an XML format, to facilitate the interpretation of coded data that we assign. Finally, we propose our API in Java programming language to build an annotation gloss as XML to create corpus or to manipulate a virtual signer as an intermediate language. Also, the new transcription system can be useful for any Sign Language Processing tool like machine translation or building n-gram models.","PeriodicalId":188977,"journal":{"name":"Fourth International Conference on Information and Communication Technology and Accessibility (ICTA)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115625098","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}

This paper considers the Competence-Based Assessment. Although attempts have been made to address some aspects of competence-based assessment, this kind of assessment has to go a step further.

In fact, they can be efficiently competing with sighted peers when they have the required assistive tools. This paper provides a systematic review of published literature related to teaching programming for blinds between 1975 and 2013. Twenty-five reviewed papers from journals, conference proceedings, and scholarly databases formed the bases for this review. To the best of our knowledge, this is the first time to make a systematic review of literature relating to teaching programming for blinds. This review categorizes the literature based on different areas of interest, while providing quantitative analysis of publications based on their type and year of publication. Finally, future research venues are explored according to the gaps found in reviewed studies.","PeriodicalId":188977,"journal":{"name":"Fourth International Conference on Information and Communication Technology and Accessibility (ICTA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128196632","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}
