This paper presents a system of speaker localization, based on the speaker recognition task. 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.

Nowadays, many Learning Environments provide a tailored and personalized learning experience to learners on the basis of information collected implicitly or explicitly about them. 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.

The evaluation of the interactive systems has been the subject of numerous researches during the last two decades. 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.

Representation of Sign Language (SL) in written form is required for the generation via avatar or any other tools of synthesis. 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.

In this paper, we present a collaborative learning environment mediatized on the Internet. For its design, we take into account all the components intervening in the interaction and collaboration process and we propose an approach guided by ontologies (domain and application). The objective of this work is to allow multiple users (learners, teachers, administrators, managers, etc.) to interact collectively with the environment. In this collaboration model, the learning users are actors of the achievement of a common problem.

Assessment is a crucial component of learning. Assessment activity is practical not only in formal learning, but also in view of employability and further lifelong training activities. In light of trends toward increased requirements for skilled workers, Web-based assessment presents today many challenges; It should address students' real performance in life. 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. Issues such as evidence, assessment grid and feedback should be tackled. This paper presents the essential components behind a competence Web-based assessment model that will lead to the design of our framework.

This paper presents a proposal to solve the need of making numerical information accessible. We use the domain of cooking recipes as a special case of study. For the numerical information in recipes to be accessible it is necessary to adapt the different mathematical forms used for the quantities of different ingredients. It is a first approach to automate the adaptation of the recipes for universal accessibility.

This work consists on achieve an automatic correction system for Arabic continuous speech. This system will be combined by an ASR system for disabled people. For this work, we built a lexicon of 4.000.000 Arabic words through which decides if a word is correct or not. A corpus of Arabic texts is also required to provide a standard summarizing the appearance rate of each two-letter (two-phoneme) in the Arabic language. The results of our system were encouraging and present an advantage to other work for people with articulatory disabilities.

Arabic sign languages still lack exhaustive scientific studies of their grammatical structure, morpho-syntactic rules, as well as the rules that govern the construction of sentences in these languages. Such studies are necessary for the development and evolution of any language (spoken or sign language). In addition, the lack of tools that help researchers and all those interested in studying Arab sign languages is another obstacle. Among these tools, we highline the importance of the availability of a language for representing Sign Language (SL) in a written form. In this context, we present a new initiative toward the creation of an Arab Gloss writing system for Arab sign languages based on gloss annotation system like American Sign Language. This new transcription system can be useful for learning, teaching or studying as well as developing Sign Language Processing tool like machine translation or building n-gram models.

Many people do not have prior knowledge about what blinds can or cannot do as programmers. 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.
