Virtual reality and its role in removing the barriers that turn cognitive impairments into intellectual disability
Early expectations of the contribution that virtual reality (VR) could make to education far exceeded actual applications. This was largely due to the initial immaturity of the technology and a lack of evidence base on which to base design and utilisation. While the early developments in computer based learning largely concentrated on mainstream education, leaving those with special needs behind, the potential of VR as an educational tool was exploited for those with intellectual disabilities right from the start. This paper describes the empirical evidence that has contributed to the development of educational virtual reality for those with intellectual disabilities: studies on transfer of learning from the virtual to the real world; how teachers might support those using VR; the design of virtual environments and what input/control devices best facilitate use of desktop VR. Future developments and ethical issues are also considered
Electric Wheelchair Hybrid Operating System Coordinated with Working Range of a Robotic Arm
Electric wheelchair-mounted robotic arms can help patients with disabilities to perform their activities in daily living (ADL). Joysticks or keypads are commonly used as the operating interface of Wheelchair-mounted robotic arms. Under different scenarios, some patients with upper limb disabilities such as finger contracture cannot operate such interfaces smoothly. Recently, manual interfaces for different symptoms to operate the wheelchair-mounted robotic arms are being developed. However, the stop the wheelchairs in an appropriate position for the robotic arm grasping task is still not easy. To reduce the individual’s burden in operating wheelchair in narrow spaces and to ensure that the chair always stops within the working range of a robotic arm, we propose here an operating system for an electric wheelchair that can automatically drive itself to within the working range of a robotic arm by capturing the position of an AR marker via a chair-mounted camera. Meanwhile, the system includes an error correction model to correct the wheelchair’s moving error. Finally, we demonstrate the effectiveness of the proposed system by running the wheelchair and simulating the robotic arm through several courses
Research and development of a versatile portable speech prosthesis
The Versatile Portable Speech Prosthesis (VPSP), a synthetic speech output communication aid for non-speaking people is described. It was intended initially for severely physically limited people with cerebral palsy who are in electric wheelchairs. Hence, it was designed to be placed on a wheelchair and powered from a wheelchair battery. It can easily be separated from the wheelchair. The VPSP is versatile because it is designed to accept any means of single switch, multiple switch, or keyboard control which physically limited people have the ability to use. It is portable because it is mounted on and can go with the electric wheelchair. It is a speech prosthesis, obviously, because it speaks with a synthetic voice for people unable to speak with their own voices. Both hardware and software are described
Travel and Transportation-Spinal Cord Injury Manual
Introduction
Travel and transportation includes driving or being a passenger in a car or van, or traveling in an airplane, bus, train or ship. After a spinal cord impairment, traveling for business or pleasure can be an overwhelming experience. Being well prepared in advance will decrease stress and make your trip enjoyable.
This chapter provides tips regarding traveling with a power or manual wheelchair, purchasing or renting durable medical equipment, medication management, bowel and bladder issues, traveling registrations and organizing recreational activities.
Driving
When you are ready to consider driving, it is suggested that you discuss financial coverage with your occupational therapist and case manager. If you are a vocational rehabilitation client, please consult with your therapist or rehabilitation counselor regarding driving evaluation, training and equipment coverage.
A referral can be made to link you up to the appropriate programs that evaluate your potential to drive safely. A comprehensive evaluation will be completed to evaluate your visual skills, motor skills, reaction time, transfer skills, hand function and driving knowledge. As a result of the evaluation, a recommendation can be made as to your ability and readiness to drive.
