Focus Group Evaluation of an Overhead Kitchen Robot Appliance
We developed and evaluated an assistive robotic manipulator called KitchenBot that operates along an overhead track built into the kitchen to assist individuals with upper extremity impairments for common kitchen tasks. Focus groups conducted with eleven participants from the potential user population revealed that potential users had very positive perceptions,…

Circling Interface: An Alternative Interaction Method for On-Screen Object Manipulation
An alternative interaction method, called the circling interface, was developed and evaluated for individuals with disabilities who find it difficult or impossible to consistently and efficiently perform pointing operations involving the left and right mouse buttons. The circling interface is a gesture-based interaction technique. To specify a target of interest,…

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,…

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…

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…

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…
