Such evaluation is important so that website administrators can change their websites so people with disabilities would be able to use them. Currently, such systems produce varying results that are not always useful for website administrators. Moreover it is difficult to ascertain for sure to what degree the web pages conform to accessibility guidelines. In this paper, the current state of open-source web accessibility evaluation tools is reviewed. As a result, AChecker, a system that evaluates web page compliance with WCAG 2.0, is identified as the best available. Three types of deficiencies in AChecker are identified, unclear comments, redundancy of errors reporting and lack of automatic or semiautomatic repair. An interactive evaluation tool (IWAET) is developed based on AChecker. The usability of the new system is studied. The study involved a group of web developers with different levels of programming experience and no accessibility knowledge. Both quantitative and qualitative approaches were adopted in usability evaluation. The developed system is compared to AChecker. The results of the evaluation are presented which show clearly the superiority of the new system compared to the currently available systems.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"66 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":"130901769","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 RMAS main challenge is how to clearly identify its local and global behavior. Several approaches have been introduced to deal with behavioral specification of RMAS. However, there is a lack in the specification and verification process that facilitates understanding the system from goals identification that the system expects to achieve to formal verification of system properties. In this paper, we are interested to the specification problem of Reactive Multi-Agent System (RMAS) for both individual and collective behavior by taking into account two modes of specification: normal mode and fault-tolerance mode. To do so, we propose a method called BECAMEDA (Behavioral SpEcification and VerifiCAtion of RMAS based on E-MDRA) for the specification and verification of reactive Multi-agent system based on the MDRA (Multi-Decisional Reactive Agent) models. The MDRA specifies the reactive agent behavior by highlighting the decisional aspect of the agent. The BECAMEDA method will be described throughout an example of Car Crisis Management.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"1 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":"126922767","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 approach consists of combining the Empirical Mode Decomposition (EMD) and band power (BP). Considering the non-stationary and nonlinear characteristics of the motor imagery EEG, the EMD method is proposed to decompose the EEG signal into set of stationary time series called Intrinsic Mode Functions (IMF). These IMFs are analyzed with the bandpower (BP) to detect the caracteristics of sensorimotor rhythms (mu and beta). Finally, the data were reconstructed with only with the specific IMFs and then the band power is employed on the new database. Once the new feature vector is reconstructed, the classification of motor imagery is applied using Hidden Markov Models (HMMs). The results obtained show that the EMD method allows the most reliable features to be extracted from EEG and that the classification rate obtained is higher and better than using only the direct BP approach. Such a system appears as a particularly promising communication channel for people suffering from severe paralysis, for instance for persons with myopatic diseases or muscular dystrophy (MD) to move a joystick to a desired direction corresponding to the specific motor imagery.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"107 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":"131571050","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}

Since the most relevant object that attracts our attention in surveillance videos is human face, we focus in this paper on building a system for indexing surveillance videos based on human face features. The proposed system has three main stages: Video Surveillance Summarisation, Face Detection, and Facial Feature Descriptors, and Indexing. A keyframe selection technique based on local foreground entropy is used for video surveillance summarisation. In the Face Detection stage, a skin color based method using measurements derived from the color-space components of the keyframe is used to locate eye, mouth and face boundary. Subsequently, SURF algorithm is applied to extract the feature descriptors of interest point from the detected face region. These descriptors are then indexed using vocabulary tree. The integration of the above-mentioned methods that are all good in their results, have made our overall system robust and efficient. Therefore, good results have been obtained while testing in ChokePoint public dataset contains 48 video sequences with a total of 179 349 frames including 64 204 face images.","PeriodicalId":375443,"journal":{"name":"2015 5th International Conference on Information & Communication Technology and Accessibility (ICTA)","volume":"10067 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":"120960744","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}
