This project is seeking to identify changes to the standard computer
interface that will improve access by elders. The identified changes
will be either alterations of settings to the default computer,
or no-cost/low-cost add ons to modify the operation of the computer.
Long-Term Functional Impact of Wheeled Mobility
Researcher: Denis Anson
It has been well documented that a high proportion of young wheelchair
users develop injuries to their shoulders, elbows, and wrists over
time. The affect of manual and powered mobility on the function
of older wheelchair users has not been documented. This longitudinal
study will track the levels of functional independence of older
users of manual and powered mobility devices to assess changes
Who Makes the Grade?: A Study of Dragon Naturally
Speaking and Speak-Q Voice Recognition with Children
Researchers: Catherine Dempsey, Bethany McCullough,
Elizabeth Mistrik, Amanda Morgan
Speak-Q is a new, novel approach to speech recognition, using it
as an assist to convetional typing rather than as a replacement for
the keyboard and mouse. The different feature set of Speak-Q makes
a traditional comparison of products meaningless. This study will
evaluate relative productivity of school-age children using Dragon
Naturally Speaking or Speak-Q, to assess the usability of these products
with a school-age population.
Text Generation: A Comparison of Dasher Software
and Wivik Keyboard with a Chubon Overlay
Dasher is a new, novel input method for text that has little similarity
to any other available input tool. This study will assess the utility
of this product for text generation as compared with a more traditional
This study is comparing the efficacy of two competing single-digit keyboard layouts. The Chubon keyboard layout, developed in 1988, is included in a number of on-screen keyboards as the "Frequency Based" layout. The Fitaly keyboard was designed as an on-screen keyboard, and does not use the conventional 101 key keyboard layout. This study will compare the typing speeds achieved by typical novice users of these device.
Efficacy of three infrared head-pointing devices for mouse emulation tasks
Amanda Berry, Stacie Hershey, Janine Hoffman and Emily Usinowicz
This study is examining the relative performance of the three head-pointing assistive technology devices that are currently readily available for use by indivduals with disabilities. These devices are the HeadMouse Extreme, for Origin Instruments; Tracker One, from Madentec Limited; and the SmartNav, from Naturalpoint.
Chubon & Dvorak: A Comparison of Alternative Keyboard Layouts
This study is part of a series to establish a standard metric for alternative text input systems. Historically, nearly all comparisons of alternative keyboard layouts have indicated that the QWERTY layout, the standard for computer keyboards, is the best, in spite of its known ergonomic deficiencies. This study, combined with past studies comparing the Chubon with QWERTY and Dvorak with QWERTY will form the basis of a demonstration that new technologies can be compared against a standard measure, in order to provide relative utility information, which will be available on the ATRI website.
