We present a robot wheelchair based on a UPS (Ultrasound Positioning System) for the elderly or the disabled. The proposed robot wheelchair system, called Smart Wheelchair, is a standard powered wheelchair equipped with a laptop computer which supports a variety of GUIs (graphical user inter-faces) for the disabled and a micro-processor system equipped with UPS and external connectivity modules. The Smart Wheelchair incorporates state-of-the-art technology providing information about the location of the wheelchair based on its movement, which is beyond comparison to ordinary wheelchairs that have just one function: to move patients. The Smart Wheelchair can provide users with driving assistance and take over low-level navigation to allow the user to travel efficiently, safely and easily. [ABSTRACT FROM AUTHOR]

We present a system for the hands-free control of a computer, using a PC camera to track head movements, then translating these movements into cursor movements onto a computer screen. The proposed system is an alternative for people with spinal cord injuries and other special needs. It can be run on a standard Windows platform and makes use of a standard USB video camera to track head movements compared to other commercial hands-free products, which use special devices. Also, it can be applied to not only the disabled but also for any users operating common devices, such as ATMs, vending machines, or pay phones. [ABSTRACT FROM AUTHOR]

It has been shown that the elderly, disabled, and those suffering from chronic illness benefit from early detection of symptoms and being involved with the management of their own conditions. We propose a home-based monitoring system which will continuously and unobtrusively (depending on a patient's condition and the sensors used) monitor a patient's condition. The monitoring system is supplemented by a monitoring/data warehousing service which is the first line of response in the event of an emergency. This system will be implemented using Zigbee technology. [ABSTRACT FROM AUTHOR]
