Needed --- Recommendation on Trackball !

21 Apr 2008 20:54:04

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
is trackball.

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 !!

Sincerely,
Lee

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.

Re: Needed --- Recommendation on Trackball !

I used Kensington's Trackball for years, no problems until I wore it out
basically. They were one of few when I started in computers and have
excellent products. I now use one made by Logitech ... it is smaller
however. I also recommend a wireless keyboard ... one finger typing is
better done on the lap in my opinion ... and mine is Logitech as well.

Check out the links for Kid-TRAC, PC-TRAC, Max-TRAC, Max-TRAC - Beige
and Max-TRAC - Black at http://lila.godel.com/html/hardware.htm.

With any model you get

1. two equally sized left and right buttons for ease
of use by left handed people and right handed people
2. a middle mouse button which works as toggle button
to turn scroll lock on and off
(With this feature text can be blocked by just
rolling the ball.)
3. a curved base that may confirm to your hand better
than the base of other devices
4. a large ball for easy control

Many of the disabled have hands that keep shaking uncontrollably. The
limited "experiments" that I've done with them --- with all kinds and
sizes of mice/trackball/tablets --- I found out that the new crops of
"cute" mice, the one they call "ergonomic", are NOT suitable for them
at all.

That is why I searched and searched the Net for something with a
bigger ball, something that is more stable, that they can use.

That 'BIGTRACK" is the one I've found.

I post this question because I need to find out if there are any other
types of trackballs out there.

Thank you for replying.

Re: Needed --- Recommendation on Trackball !

Thanks for replying !!

I searched the net for days, and the only one so far that I've found
is BigTrack. The ball is big enough for those who have frail hands,
and for those whose hands keep shaking uncontrollably.

I'm glad that BigTrack works for your uncle.

Again, thanks for replying !!!

Re: Needed --- Recommendation on Trackball !

I used to use a Kensington trackball for many years, the one with big
ball. I agree with you, it's a good trackball.

Unfortunately, Kensington doesn't make trackballs with big ball
anymore.

What they are making now are those "cute-cute" stylish trackballs.
While those might be okay for the able-body people, disabled people
with hands shaking uncontrollably just can't use those "cute"
trackballs.

Thanks for replying !!

Re: Needed --- Recommendation on Trackball !

pg,
If the disabled people who will be using this computer lab have clear
speech, consider adding speech recognition software to some or all of your
computers. This is particularly easy to do if you are using Windows Vista,
as the operating system has a fairly comprehensive Microsoft compatible
speech recognition program built right in to it. Look in the ease of access
section of the control panel. It provides multiple ways to position the
mouse including both "Show Numbers", which assigns a number to each icon on
the desktop or web page, and also a traditional Mouse grid option.

Re: Needed --- Recommendation on Trackball !

We already have the speech recognition thing installed. It's the hands-
on input device that we need to take special care of.

One of the aim for the computer lab is to encourage the disabled to
use their hands, however frail their hands may be.

Encouragement is the key, not frustration. The current crop of "cute"
mice just frustrated the disable too much.

I have a Kensington TurboMouse, Model 64100. It's ADB for a Mac. The ball
itself is 2.25 in. in diameter. There is one for sale on eBay: http://
cgi.ebay.com/KENSINGTON-TURBO-MOUSE-TRACKBALL-APPPLE-Mac-
ADP-64210_W0QQitemZ250136760153QQcmdZViewItem

If you think you can adapt this for your use, I'll send you mine for the
cost of shipping.

At RS Componets they sell trackball mechanisms for industrial use.

They should be easy to mount into a custom enclosure with buttons
added as required.

Micro-speed trackballs were one of the _worst_ rolling larger
trackballs I ever used. At work and home I have 2 Kensingtons Expert
Mouse - nice because its very easy to clean the ball after little
kids, and 3 Mouse-Traks by Itac. WAY expensive but very well built but
super when I got 3 on eBay for $15 each. Micro Speed is frustration
(lots of it) in waiting.
