Hi, all !
I am setting up a computer lab for the disabled. We are looking for
equipments that might aid the disabled (mainly those who are not that
good in movement), and one of the things we are planning to get them
There are many types of trackballs available, unfortunately most are
made for the able-body people. I am looking for something that can be
used by the disabled with ease.
Our objective is that the trackball must be big enough, and easy
enough to be used.
One of the things we have found is the BIGTRACK trackball made by
infogrip ( www.infogrip.com/product_view.asp?RecordNumber=98 )
I want to know if there are other types of trackball similar or better
than the BIGTRACK that I list above?
If you have any experience on which type of trackball that will be
easy for the disabled, please share with us.
Thank you all in advance !!
I purchased one of the BIGtrack trackballs for a 70 year old relative who
has limited dexterity in his hands due to an industrial accident.
He tends to loose his temper while playing computer card games and gets a
little ruff with things, not that anyone could ever get him to quit playing
the games. He never used a computer until he was 65 and has become quite
addicted to the games available to him.
Prior to purchasing the BIGtrack trackball he had either worn out or broken
three other trackballs. The Kensington trackball lasted the longest before
suffering a fatal break in one of the roller guide supports. He was always
complaining that even when the other trackballs worked he had a hard time
keeping the pointer where he wanted it.
It has been 6 months with the BIGtrack unit and he has not complained once
about controlling the pointer. He has commented that he liked the larger
sized trackball that the unit provided. It has withstood his somewhat
physical temper tantrums with no breakdowns, so far.
There is one thing about the BIGtrack trackball that takes a little getting
used to. The mouse buttons are on the top of the trackball, away from the
person rolling the ball. I thought the button placement to be a little odd
at first but it does help in reducing most accidental button triggering by a
random hand or arm movement.
For those who have even more severe limitations I suggest getting the
BIGtrack unit that supports external buttons. That way you can place the
buttons anywhere convenient for the user independent of the trackball. Be
they foot activated or strapped to the arm of a wheel chair.
