Use of eye-tracking systems as a computer-input method to advance communication and visual behaviors has been recognized as effective for educating students with severe physical disability. We have also examined that technology for students with severe physical and intellectual disabilities (SPID), including profound intellectual and multiple disabilities (PIMD). We hypothesized that a calibration-free system can be useful for such students because it completely reduces the calibration load of any application software. Our earlier research supported the hypothesis, but highlighted the need for a more compact system. This research examined a compact-type calibration-free eye-tracking system for such students. We developed a prototype based on a compact 19-inch (48 cm) display. Results of trial use by two students in a special school suggest the prototype effectiveness, but additional difficulties were pointed out for the system fixation and long-term use by many more students.

This paper examines the effectiveness of the Google Classroom App in learning for higher education institutions in Oman. The massive advancement in technology has contributed to changes in learning and delivery of learning resources in the classroom. Thus, it has saved the resources and reduced the cost of learning associated with the traditional learning model. The main goal of this paper is to investigate the students' perception about the cloud computing services accessibility, ease of use and usefulness by measuring the implementation effectiveness of Google Classroom as a mode of teaching. This study used quantitative approach mode to determine the effectiveness and the effect of using Google Classroom e-learning model, 225 completed questionnaires were analyzed using SPSS tool. Its evident that using Google Classroom for the learning is more effective and gained highest level of satisfaction among the learners. As a general result of this work students can use Google classroom in very comfortable and easy way really on the ability of online, remote, and time unconstrained conditions. The students also like to learn through the lecturer with the support of google classroom.

Using Machine Learning to the user perception prediction has largely increased in the last decade. Although it is difficult to deduce the best category model to address the predicted Quality of Experience QoE in operational networks. Also, sometimes the result obtained by ML is not relevant i.e not expected according to the present conditions. We talk here about problem of anomaly in Machine Learning context. To fill this gap, in this paper, we try to solve the problem of Machine Learning ML anomaly detection in the QoE context for video streaming service in Software Defined Networking SDN environment. We explore in one hand feature selection methodology to extract the most correlated features to the video QoE. In other hand we investigate different ensemble learning approaches to improve the detection of QoE anomalies following the known stacking or super learning model. Results show that the proposed model presents a high performance comparing to other types of ensemble learning and single learning techniques.

Humans prefer to interact with their smart devices through speech rather than using pointing tools and keyboards. Recent mobile devices provide the capability to automatically convert voice to text but they still suffer from many issues when it comes to efficiency goal. In this paper, we present a new approach for vocal commands processing based on Information Retrieval concepts (i.e. text pre-processing, cosine similarity) as well as machine learning algorithms and which enables mobile smart devices to better and faster access to applications' functionalities.

In this paper, we propose a framework for building automatic recommendations of answers in MOOCs' Discussion Forums. The general aim of this research is to contribute to addressing the MOOCs' dropout rate issue due to the lack of interactivity and scaffolding for learners especially in discussion forums. To this end, the proposed system provides learners with automatic adequate answers to the inquiries and questions they posted in discussion forums. The proposed answering approach is accomplished in two main phases: The Answering System identifies firstly a learner's question among a panoply of exchanged messages within discussion forums. Then, it provides to the learner suitable suggested answers based on similar existing posts, which would help the learner getting immediate preliminary answers without the need to wait for a formal feedback from the instructor. In a second hand, the system builds and recommends an appropriate answer using MOOCs' videos, based on automated crawling and indexing methods and applying web mining and recommendation strategies.

Learning Analytics has gained significant attention in the domain of higher education. It involves dealing with the development of tools that harness educational data sets to enhance the learning process. It is a very active and promising research field. In this paper, we propose an insight by investigating how LA and its relevance can be used to improve the continuous improvement process. This can be considered as an initial step towards establishing a general framework for improving the educational outcomes, developing a real-time continuous improvement process, and enhancing students' learning experience in the Information Technology Bachelor Program at King Saud University.

The paper presents some recommendations on how to foster the adoption of open education practices within universities starting from the capacities and challenges of university educators, based on the central role that educators play within the process of adopting openness within higher education. Those advices derive from the research work run within the Open Educators factory project, that has collected data from more than 1000 educators worldwide on their level of adoption of open educational practices, ad want to represent starting points for discussions on how to implement openly in a useful and cost-effective way within universities.

The adoption of the Internet of Things (IoT) in the medical sector improves health care services and guarantees continuous and efficient monitoring of patients with chronic disease. Accordingly, heterogeneous health data (medical devices and medical records) is obtained and requires to be efficiently managed and diverse risk factors should be smartly considered in order to predict and prevent complex and dangerous events. The modeling and processing of this kind of events present an emerging challenge that necessitates to be addressed. In this context, we aim to propose a semantic-driven complex event processing approach for Cardiovascular Disease (CVD) prevention for diabetic patients. Particularly, we focus on the semantic modeling of medical events; Then, we propose diverse rules for processing purposes.

In this paper, we deal to understand how the conversational agent (avatar) can achieve human-friendly Sign Language interpretations to improve web accessibility to people with hearing disability and hearing impairment with a low level of literacy. One of the key element in Sign Language is the prosodic pauses during a conversation in Sign Language applied in a machine translation or in real-time interpretation using assistive technologies. We introduce the importance of the prosodic pauses in Sign Language through several examples. After that, we present an approach to recognize prosodic pauses from Motion-Capture and Video-data based on the sentence syntax and other grammatical features.

Persons with cognitive disabilities (CD) can benefit from using technologies to support their health and independence. However, these users often struggle to access and use technologies because their needs are not accounted for in most technology development processes. One of the main reasons for this is because technology developers often experience tension between accommodating the needs of these users with feasibility considerations. In this case study, we describe our transdisciplinary, inclusive and iterative process for reconciling users' needs and feasibility considerations when developing a medication management app for persons with CD. This paper may serve as a valuable resource for technology developers who are interested in developing products for persons with CD, by highlighting some of the real-world challenges they may encounter and providing guidance on how to overcome them.
