Intelligent single switch wheelchair navigation
•
We have developed an intelligent single switch scanning interface and wheelchair navigation assistance system, called intelligent single switch wheelchair navigation (ISSWN), to improve driving safety, comfort and efficiency for individuals who rely on single switch scanning as a control method. ISSWN combines a standard powered wheelchair with a laser rangefinder, a single switch scanning…

Effectiveness Of Morse Code As An Alternative Control Method For Powered Wheelchair Navigation
•
We applied Morse code as an alternative input method for powered wheelchair navigation to improve driving efficiency for individuals with physical disabilities. In lab trials performed by four testers, it demonstrated significant improvement in driving efficiency by reducing the driving time, compared to traditional single switch wheelchair navigation.

Modeling an Automatic Adjustment of Scanning Rate Using Fuzzy Inference Logic
•
Single-switch scanning is one of the slowest way for people with severe motor impairments to access a wide range of assistive technologies, such as entering text into computer applications, manipulating alternative and augmentative communication devices, and operating power wheelchairs. Automating scanning rate adjustment has been investigated as a means of improving selection rate by…

The Use of Microsoft Windows on Intel-Based McIntosh Platform
•
The successful use of micro computers is regarded as the fundamental necessity for an occupational and educational placement of people with visual impairments. People with visual impairments have long been actively adopting computers and assistive technology devices as integral parts of their lives. For example, 2002 NTIA survey reported that people with visual impairments…

On-screen Target Acquisition through Mouse Movement Recognition
•
In this paper we present a new design idea as an alternative to improve on-screen target acquisition for individuals who have difficulty pointing by inferring the user’s intended target from the user’s mouse movements. The intended target is inferred based on real-time mouse movement information and the properties of all user interface elements currently…
