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)
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)
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 paper presents a hardware architecture for implementing a mobile robot localization approach through encoders' measurements and absolute localization using camera tracking images. This technique has been developed and implemented for the motion of the robot from an initial position towards another desired position, taking into account the tradeoff(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)
Augmented reality (AR) systems emerged and become a very gifted 3D embedded multimedia application. AR consists on adding specific 3D's animations on a video flow. The design and the implementation of such systems on FPGA are complex and difficult. To reduce computational resources that must be carefully used to execute complex application. This execution(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)
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)
