Provide Early Access To Computer Technology
• Exploration– Provides opportunity to explore– Assist with development
• Play– Independent play – Interactive play– Decrease learned dependency
• Learning– Early access – Software to assist with learning

Identify Equipment Needs• Laptops:
– Portable– Mounted to a wheelchair– Placed on a bedside table
• Mouse• Right and Left Clicks• On Screen Keyboards/Low Profile
Keyboards• Software

Environments
Whether the child is in school, active in the community or at home, multiple considerations for accessing a computer are important
• From a wheelchair• Bed• Alternative positioning devices
Aaron W. Perlman Center
• Seating and Positioning must be established
• Locate the strongest, most reliable access site or multiple sites
• Keep in mind the access must be used in all environments or allow for alternative access for bed/alternative seating
Locate an Access Site
How is the child going to access and use a computer when they have limited movement?

Mouse Function
• Trackball– Require a small excursion for
travel– Hand placement remains the
same– Speed of cursor can be
controlled– Switch ports for L/R clicks
• Trackpad– Can use one finger– Hot buttons can be added– Switch ports for L/R clicks

Right and Left Clicks
• Established through the use of switches– Mechanical Switches require force– Proximity Switches: no force but require a
power source
• Dwell software– Ability to place cursor on a target and
automatically click: time determined

Switches
• Sensitive switches: Little movements require switches with a light touch
– Micro Light - Activated by pressing down on the top surface with a feather light touch!
– Leaf- Activated by pressing lightly against the leaf in one direction.

Proximity Switches
– For lengthy tasks or frequency of use an electronic switch is less fatiguing
– Electronic switches require a power source• WC battery• Power adapter for manual chairs
– More expensive– Require no force/ pressure– Becomes transparent to the user– No auditory feedback

Cruise• Cruise requires no hand or wrist movement, and unlike a
touchpad, the cursor does not have to be “guided” around the screen by constant finger movement.
• Control the speed and direction of the cursor with a single, soft touch of its control ring.
• Cruise can store personal settings for automatic retrieval each time the computer is powered up.
• Limitation: Size and placement
