The effectiveness of assistive devices for disabled people is often limited by the human machine interface. This research proposes an intelligent wheelchair system especially for severely disabled people based on analysing electroencephalographic signals by using discrete wavelet transform and higher order statistical methods. The system to be implemented in Field Programmable Gate Array enable...

ii Development of a Robotic Wheelchair Abstract Robotic wheelchairs extend the capabilities of traditional powered devices by introducing control and navigational intelligence. These devices can ease the lives of many disabled people, particularly those with severe impairments, by increasing their range of mobility. A robotic wheelchair has been under development at the University of Wollongong...

Background The World Health Organisation recommends that services accompany wheelchair distribution. This study examined the relationship of wheelchair service provision in Kenya and the Philippines and wheelchair-use-related outcomes. Method We surveyed 852 adult basic manual wheelchair users. Participants who had received services and those who had not were sought in equal numbers from whee...

An assistive system easing wheelchair control for severely disabled users is presented. To compensate for the restricted information that can be provided using speciality controls, the person’s gaze is used to estimate the intended motion direction. The novelty of the presented method is that motionrelevant portions of natural gaze behavior can be distinguished from non-relevant. Producing whee...

Two prototypes of a 9-DoF wheelchair-mounted robotic arm (WMRA) have been developed as assistive devices, consisting of a 7-DoF robotic arm and a 2-DoF power wheelchair. Combined kinematics and redundancy resolution have been previously implemented. In this work, we focus on control methods to allow autonomous mobility and manipulation for the execution of activities of daily living (ADL). Resu...

Young children with severe motor impairments face a higher risk of secondary impairments in the development of social, cognitive, and motor skills, owing to the lack of independent mobility. Although power wheelchairs are typical tools for providing independent mobility, the steep learning curve, safety concerns, and high cost may prevent children aged 2 to 5 years from using them. We have deve...

Natural language is a flexible and powerful control modality which can transform a wheelchair from a vehicle into a genuine helper. While autonomous wheelchairs are increasingly designed to use natural language for control, most of them only handle a small number of rigid commands. To establish the state-of-the-art in language-enabled wheelchairs and determine how to improve natural language ca...
