This new, one-of-a-kind resource can serve as a textbook or a clinical tool for computer-based assistive technology. The book assumes that the reader is familiar with the process of physical and cognitive evaluation of the client with a disability. Little or no prior knowledge of computers is required. Illustrated.
Tells how to use the computer technology that now exists to overcome orinimize physical problems with speech, learning impairments, paralysis, andther disabilities.
Incorporating Compass Computer Access Assessment software, Computer Access for People with Disabilities: A Human Factors Approach provides the information clinicians need to know in order to provide effective alternative computer access solutions to individuals with disabilities. Originally developed for a masters-level course on computer access fo
Individuals with disabilities that impede their range of motion often have difficulty accessing technologies. With the use of computer-based assistive technology; devices, tools, and services can be used to maintain and improve the functional capabilities of motor disabilities. Assistive Technologies and Computer Access for Motor Disabilities investigates solutions to the difficulties of impaired technology access by highlighting the principles, methods, and advanced technological solutions for those with motor impairments. This reference source is beneficial to academia, industry, and various professionals in disciplines such as rehabilitation science, occupational therapy, human-computer interface development, ergonomics, and teaching in inclusive and special education. This publication is integrated with its pair book Disability Informatics and Web Accessibility for Motor Limitations.
Discusses the use of computer technology to overcome or minimize physical problems with speech, learning impairments, paralysis, and other disabilities.
Recent advances in eye tracking technology will allow for a proliferation of new applications. Improvements in interactive methods using eye movement and gaze control could result in faster and more efficient human computer interfaces, benefitting users with and without disabilities. Gaze Interaction and Applications of Eye Tracking: Advances in Assistive Technologies focuses on interactive communication and control tools based on gaze tracking, including eye typing, computer control, and gaming, with special attention to assistive technologies. For researchers and practitioners interested in the applied use of gaze tracking, the book offers instructions for building a basic eye tracker from off-the-shelf components, gives practical hints on building interactive applications, presents smooth and efficient interaction techniques, and summarizes the results of effective research on cutting edge gaze interaction applications.
Current access technology for people with disabilities is based on a concept called transparency. Developers have generally interpreted this by building access systems that emulate the keyboard and mouse. In contrast, this thesis proposes and studies a refinement to transparent access, called task transparency. This approach has much potential impact on scanning access within a GUI. Here, scanning is applied to the underlying tasks, rather than emulating the input devices. The goal is to derive new knowledge and understanding of the interactions that arise with a number of strategies that apply switch-based scanning to text selection in a task transparent fashion. In the case of selecting text, it was demonstrated that directness to the task could be achieved with minimal effort by applying scanning within the text area itself. The concepts are readily extended across other GUI objects including menus, buttons, and window controls. These objects can be incorporated within the access system such that they are directly engaged in the scanning. Through such strategies, users can significantly reduce their efforts and in doing so achieve greater overall productivity, and accomplish tasks that are otherwise strenuous. Text scanning was implemented using repeating keys injected by an on-screen keyboard such that the user perceived scanning in the text area. Two test applications were developed and used to evaluate a number of proposed text scanning strategies. In addition, predictive performance models were derived to predict performance measures under error-free conditions. Initial design guidelines for scanning in a task transparent fashion were also formulated. An access system developer could extend the concepts in new ways with scanning and other access methods. Future areas of research are identified that may improve overall productivity. Through this work I have contributed new knowledge towards improving scanning access and I have demonstrated the feasibility of task transparency by which further gains are possible.
