This paper presents a description of an intelligent control method for controlling an electric wheelchair for several disabled persons. It also describes a non invasive approach based on EEG brain signal that can command the wheelchair with cognitive data, eye movements and head gestures. Our technique aim is to cover the largest number of handicapped(More)
Optical character recognition (OCR) has been an active subject of research since the early days of computers. Despite the age of the subject, it remains one of the most challenging and exciting areas of research in computer science. In recent years it has grown into a mature discipline, producing a huge body of work. In this paper, we present an Arabic(More)
We are now witnessing the beginning of Ubiquitous Computing era with the success of several start up to find early adopters among the general public for their home automation solutions through crow funding campaigns. We believe that in the near future, more and more people will come out with new ideas in relation with ubiquitous computing to make our daily(More)
The real-time applications have a growing complexity and size which have to be well controlled. They can be viewed as a set of synchronized tasks, communicating and sharing critical resources. One of the main difficulties in the real-time application design is time constraints meeting. All tasks have to be running before their predefined deadlines. At this(More)
Virtual reality applications grow up nowadays. These applications are not only developed for the PCs but also for embedded systems such as game console, Smartphone, touchpad. The limited touchpad resources and network communication between touchpad need an adaptation to environment noises. To solve this type of problem, we'll test a 3D application(More)
The complexity of System on Chip (SoC) design is increasing continuously with the use of MultiProcessor System on Chip (MPSoC) architectures. Mastering the complexity of these systems with a typical co-design workflow is really recommended. As such, computer aided design tools are needed to alleviate the task of designers. There is a lack of co-design tools(More)
The growing number of complex multimedia applications has raised new challenges in the design of embedded mobile multimedia systems. These systems must be able to react to resource limitations and external environment fluctuations to meet applications' timing constraints and provide an acceptable service. In this paper, we present a new adaptation technique(More)
Internet of Things (IoT) is currently leading the next world revolution. We witness more and more wearable devices and soon, all everyday objects will have a tiny computer. The ultimate objective of IoT is to leverage the technology abstraction as much as possible. Several fields are benefitting from the IoT revolution, among them we cite electronics,(More)
The embedded systems are more and more complex. They must answer to contradictory constraints. Indeed, these systems integrate new functionalities that require high performance architectures. At the same time, these systems must be flexible and adaptive since they work in a fluctuating environment and have a quite unpredictable workload. In order to answer(More)
