In this paper, we propose an efficient online personal identification system based on Multi-Spectral Palmprint images (MSP) using Hidden Markov Model (HMM) and Principal Components Analysis (PCA). In this study, the band image {RED, BLUE, GREEN and Nearest-InfraRed (NIR)} is rotated with different orientations then applying the PCA technique to each oriented image, to decorrelate the image columns, and concentrate the information content on the first components of the transformed vectors. Thus, the observation vector is formed by concatenate some components of the transformed vectors for all orientations. Subsequently, we use the HMM for modeling the observation vector of each MSP. Finally, log-likelihood scores are used for MSP matching. Our experimental results show the effectiveness and reliability of the proposed approach, which brings both high identification and accuracy rate.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128111853","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}

These latter, which are increasingly being incorporated into TEL, and seems to be a promising concept for making learning easier for students. The application of these concepts in traditional learning is almost impossible as we only have one teacher with thirty or even hundreds of students in a class, so he can not apply an adaptive learning for each of them. However, the emergence of adaptive learning management system (LMS) offers a great advantage for students, as it allows them to have a personalized learning process that can be suited with their needs and characteristics. Now days, many researchers has been working in this area. The purpose of this article is to propose a learner model ontology SLMonto based on popular student modeling standards. As well as the representation of the prior knowledge of the student's performance, motivation, and the learning style which is adapted from Felder-Silverman Learning Style Model.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121893167","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}

In particular, working memory capacity plays an important role in learning process, because learner often have to hold information in mind while engaged in a learning activities. Having information about learners' WMC could be helpful to support them during the learning process. Khenissi et al. [1] proposed an approach based on fuzzy logic for learner's modeling while using educational games and/or e-learning system. This paper will detail the description of the mechanism proposed by Khenissi et al. [1]. Furthermore, it will describe how the system architecture will be improved by the automatic generation of the fuzzy logic components. In particular, the machine learning, web services and the model of educational games are adopted for automatically generate the components of the fuzzy logic system. The automatic generation of these components will help the expert in parameterizing them, and thus better estimation of the learner's WMC.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131445448","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 student is thus as a passive recipient of information without reacting or participating in resolution of real problems. Given the evolution of learning methods, teachers now have the opportunity to introduce games with an educational purpose to facilitate learning. The Serious Games is a continuous evolution and accelerated. This type of learning is integrated in teaching and in several areas. It is used to combine both serious aspects such as teaching, learning and playfulness through these games. After the learning process, assessment is the most important step in determining the learning' and the level of validation of learning objectives through the use of different valuation technics. It is therefore interesting to involve learners in the assessment process. This paper presents a novel approach regarding self-assessment in serious game. We address the needs of serious games as well as a review of existing research work in this field. To enrich learning aspect of serious games, we propose the integration of self-assessment modules in serious games. This integration is reflected in the design of an ontology representing different concepts.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129218959","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}
