“…A robotic wheelchair can be used to allow people with both lower and upper extremity impairments or severe motor dysfunctions overcome the difficulties in driving a wheelchair. The robotic wheelchair system integrates a sensory subsystem, a navigation and control module, and a user-machine interface to guide the wheelchair in autonomous or semi-autonomous mode (Mazo, M., 2001;Bourhis, G. et al, 2001;Zeng, Q. et al, 2008;Parikh, S. et al, 2007). In autonomous mode, the robotic wheelchair goes to the chosen destination without any participation of the user in the control process.…”

“…*** In this context, the final user capabilities determine the type of human machine interface (e.g. voice [7], [6], graphical [4], [10], [7], [6], [13], joystick [4], [7], [5], and eyes or air expulsion [7]). In our case, we collaborate with a school for people with cognitive disabilities.…”

Abstract-In this paper, we describe the adaptation of an autonomous robotic wheelchair for cognitive disabled children. The constraints imposed by these users require developing specific human-machine interfaces adapted to their limitations. In most cases it is necessary to develop additional tools to teach the children the spatial relations between the wheelchair, its motion and the environment. In addition to this, it is important to interact closely with the children and their educators. The paper describes the whole process followed to make the children use the autonomous wheelchair and the lessons learnt during the validation phase with the wheelchair and the children.

“…Devices related to the control of a wheelchair [3], projects using virtual reality technology [4] and camera-based systems [5], [6] have been implemented for rehabilitation purposes. Several projects use reconfigurable logic devices, such as field programmable gate arrays (FPGAs) [7], which undertake the control of the system [8]- [10]. It should be noted that essentially all of the above projects use at least one of the following: 1) large or multiple FPGAs; 2) PC-class fixed computer resources; or 3) expensive equipment to make all necessary data acquisition and calculations.…”

Abstract-A low-cost reconfigurable embedded apparatus for two-dimensional (2-D) motion detection has been developed. This paper briefly outlines the embedded reconfigurable system architecture, and presents in-depth the 2-D motion detection model, which is directly mapped to reconfigurable hardware. Emphasis is placed on the hardware ability to adapt to individual needs of kinetically challenged persons by altering detection thresholds and delays, thus resulting into an efficient low-cost reconfigurable hardware implementation of the model. This paper also presents how the model detects complex motions through a vocabulary of simple motions, and how the system is trained to individual users' needs. Experimental results and integrated applications of the model for text processing are also presented.Index Terms-Input/output (I/O) device, kinetically challenged, reconfigurable embedded system, 2-D motion detection.
