Subject: Designing an augmentive lab
Date: 23 Jan 93 13:45:24 EST
Organization:  Wright State University 

     The attached configeration is a 9 station personal computer
laboratory complete with adaptive equipment and furniture that will
allow virtually all students with diabilities the same connectivity
as their able-bodied counterparts.  This project was completed
using the expertise of the Computers and Technology Committee for
the Handicapped (CATH), the departments of Handicapped Student
Services and Academic Computing Resources at Wright State
University, Dayton, Ohio.

     There are four basic components to each station.  The
components are:
     
     1.   Processing Hardware.  This component provides the
          basic computer functionthat is available to all users. 
          The type is standard to existing laboratory facilities
          within the university.  Only two stations required
          unusual components due to adaptive equipment
          configuration or user needs.  All stations except one are
          IBM compatible equipment.  One station does use MacIntosh 
          equipment.  These decisions were based on a student
          survey conducted April of 1991.  The requested packages
          upgradable and should remain current for 3-5 years.  An 
          additional year of warranty has been provided by the
          manufacturer.  This brings the total on-site warranty   
          package to three years.  This includes lab maintenance  
          costs.  A single printer is planned as well as connecting 
          to the network laser printer and braille printer.  This
          will allow assisted or unassisted printer access.

     2.   Adaptive Equipment.  These pieces of equipment are
          necessary to provide easy and reliable access to a large 
          percentage of the disabled student population.  The
          equipment is divided into two categories:  Adapted input 
          (the way data is entered), and adapted output (the way
          data is returned to the user).  The input includes      
          keyguards which prevent adjacent keys from being pushed 
          by students with poor dexterity, enlarged or miniaturized 
          keyboards for students with exaggerated or limited hand
          dexterity, and the final category, input devices that
          offer the student each keyboard by activating either a  
          pneumonic, infrared or mechanical switch.

          The output group is in three areas:  enlarged format for 
          students with limited vision; voice output for students
          who access auditorily due to sight or learning
          disabilities; braille access using the existing braille 
          printer and translation software.

     3.   Assistive Software.  The laboratory will contain a
          variety of software that assists and adapts both the    
          input and output of the machines.  An example includes  
          programs necessary to drive the voice synthesizer for   
          auditory output.  A package of software that limits the 
          number of keystrokes necessary to type a single word is 
          also planned.  The ability to change the size of print or 
          graphics in the video display will also be available in
          a software package.  Because the stations will be
          networked, most software will be placed on the network  
          server and students who have these needs will be given  
          appropriate access codes.  This will also insure software 
          security.

     4.   Adaptive Furniture.  Because students with disabilities
          present limitations that can be overcome by raising,
          lowering or tilting the surface of the computer keyboard 
          or video display, a package of furniture including
          monitor arms, copy holders and stand that raise, lower  
          and tilt were chosen.  Although some of the students use 
          wheelchairs, each station will have a chair to insure
          seating for lab assistants and staff who will use the
          lab to train students with disabilities.


As the footprint for the lab, we chose the IBM PS/2 Model 70-a81
with 4 Mbytes of RAM, either a 8512 or 8514 Monitor, 2 3.5" Disk
Drives, DOS 5.0, 80 meg Hdisk and Mouse.  IBM was chosen after
careful consideration of other computer systems including NCR and
Emerson.  Reasons for chosing IBM included quality of equipment,
and most compatible with needed augmentive devices.  IBM also
promised the best response in the service contract and turnaround
replacement/repair time was far better than offered by other
vendors.

Please note:  The following prices for equipment were the original
prices as quoted when we ordered.  Some prices changed but I do not
have that information.  Also, since this equipment was ordered
during the summer of 1992, prices quite likely have changed since
then.  I am giving you the prices as information only and as a
ball-park guideline so that you can have some rough idea of costs.
Some modifications were done to the final order, due to price
changes.  

Funds for the lab were obtained from House Bill 808 money.  A total
of $120,000 was requested in the original grant proposal, $90,000
was granted.  This required us to cut back from our original lab
design which included a DragonDictates System.  We are still hoping
to be able to find funds somewhere, somehow to be able to obtain
the DragonDictates System.  












                           Station # 1

This unit will provide access for students who have exaggerated
movements or who are unable to press multiple keys or switches. 
The devices will allow us to adjust the angle and level of
switching device or use an infrared head pointer to activate the
computer.

operate keyboards with chin controller or other switches available
from Station 1.  Due to the high density of quadraplegic students,
a second unit has been designed for Station 9.

This unit will provide access through either an enlarged or
miniaturized keyboard.  The miniaturized one is used for
individuals who have dexterity but limited arm strength.  The
enlarged version will provide backup access for students who have
exaggerated movement as well as students who have limited vision.

will also be a print enlargement system to allow students to read
textbook material, rough drafts, or instructions while working on
the computer.

                           Station #6

This station will provide visually impaired and learning disabled
students with scanner capabilities that will not only store printed
materials, but the disc can be replaced on either this station or
stations 5 or 7.  Thus, students will have access to text (eg.
notes, handouts, reference materials, etc.) in an editing fashion.

                           Station #8

Because a significant number of students indicated on the survery
that they would use a MacIntosh, one station was dedicated to that
use.  Although limited adaptive equipment is available, all
students will be able to operate the MacIntosh.  Many of these need
only to use an adaptor to move the equipment from an IBM compatible
station to a MacIntosh station.
