Sessions Break Down
Identification: Basic Computer Access Assessment
This session will break down the basic domains of computer access. The importance
of focusing on a specific desired computer task when assessing will be examined.
Compass computer access assessment software from Koester Performance
Research will be presented.
Application: AT for Computer Access
This session will present software and hardware applications for computer access.
Mouse and keyboards options along with desktop/text enlargement, audio text
/navigation, and text/command entry software will be presented.
Integration: Multiple Technologies Working in Concert
This session will integrate all previous discussed software and peripherals in sessions
1 and session 2 into a” working concert” Mounting devices will be review for switch
access and discussed peripherals. Eye-tracking technology from Eye Response
Technologies will also be presented by Mel Ellison from Learning Resources
Assistive Technologies.
Identification
Session 1
Basic Computer Access Assessment
First must review
“Computer Access”
The Basics of
Computer Access
Session 1

Physical location of the computer

The computer skill level of the individual

To use a computer you need output / input
(Need one or more Peripheral)

Know what you want to do on the computer
(In measurable and observable terms)
Physical Computer Location
Session 1

Is the computer accessible from a
wheelchair?

Is the computer table adjustable?

Is the “CPU” the box on the floor?
Adjustable Computer Table
Session 1
A person’s positional needs in computer access
should to be reviewed by a PT or OT
Assistive technology can help position computer peripherals
with mounts and adjustable tables and chairs

Session 1
For an individual to work with a
computer they need to “see” or “hear”
the desktop or computer screen.
Ways to help to see
Session 1

Session 1
Once one has received information from
the computer they need to be able to
respond
Point
Select
Enter Text
How do we Point?
A Mouse
Session 1
Pointing with a Mouse
Session 1
In computer access you need to think of moving the mouse cursor not the
mouse!
Mouse Cursor
Session 1
Think of your mouse cursor as your Pointer!
Other ways to Point
Session 1
Options for individuals that can not point with a mouse
Can also use Pointing Devices
These are hardware devices

How do we Select?
By Clicking!
Session 1
Mouse Clicking
Session 1
A mouse click is nothing more than a switch
You are pushing or activating a button to make a selection
Select
Session 1
To make a selection you point then
Click a mouse
Instead of using a mouse click for a selection
Push
button/switch
use aavariety
of switches
Dwell
you can
Dwell?
Session 1
Dwell is automatic clicking
(or selecting)
Software that allows you to aim and (dwell over)
a target and select without clicking your
mouse or switch

Other Text Entry Methods
Session 1
Voice to Text Software
“Voice Recognition allows a user to use his/her
voice as an input device. Voice recognition may be
used to dictate text into the computer or to give
commands to the computer (such as opening
application programs, pulling down menus, or
saving work)”
Dasher
Session 1
Is a pointing (zooming) text entry interface
Software that allows you to point to letters to type.

Computer Access
Session 1



The computer skill level of the individual

To use a computer you need output / input
(Need one or more Peripheral)

Know what you want to do on the computer
(In measurable and observable terms)
What tasks
do they want to accomplish?
Session 1
Get on Internet, Read Email, Do my job,
Do Homework, Research, Learn, Math,
Communicate, Play Games, Make Lists,
Banking, Get Pictures, Draw, Make Movies,
Design, Create, Listen to Music,
Increase Computer Skills.
Must be Specific of the Task
Session 1
If someone says “I have trouble using the
mouse”
Ask in moving the cursor or clicking?
If someone says “I have trouble typing”
Ask can you not use the keyboard at all
or are you not satisfied with words per
minute?
Get very specific!
Example: Typing
What are you typing?
 Short emails
 Data entry
 Long paragraphs
In what program/s?
 Outlook
 Excel
 Word
Session 1
What drives AT?
Session 1
Assistive technology is driven by the Task
not the disability!
A person’s disability does help steer a
device or program but is not the driving
force.
