Overview
The Twiddler2.1
TM
provides the same input to your computer as both a conventional
keyboard and a mouse. To do this the Twiddler uses twelve keys on the front and four keys on
top plus a NavStick. The top keys are for your thumb and your other four fingers operate the
front keys. The Navigational Joystick, or NavStick, under your thumb, performs the pointing
function of a mouse. The Twiddler is designed to be operated by only one hand while the
hand not holding the Twiddler is free for other tasks.
The Strap
There is a soft fabric strap that extends from a slot in the side of the Twiddler’s case and
attaches to a Velcro pad on the bottom. This strap goes around the back of your hand and
holds the Twiddler in posi tion for typing or pointing. When you receive your Twiddler, the strap
will be set up for right-hand use, but it may be easily readjusted for left-hand use.
Changing to Left-Hand Use
To adjust the Twiddler for left-hand use, first remove the strap from its Velcro fastener on the
bottom. Next, grasp the strap close to the slot and slide the end of the strap out of the slot. It
is designed to be a snug fit. Then slide the same fitted end of the strap into the matching slot
on the opposite side of the Twiddler. Be sure to insert it all the way into the slot.
Getting Started: Left or Right?
Which hand should you use for the Twiddler? The first inclination is to use it in your dominant
hand. But you may wish to put off this decision and try the Twiddler with each hand and
think about how you will be using it before you decide.
Here are a few things to consider:
1. What do you want to be able to do with the hand not holding the Twiddler?
If you want to take pencil-and-paper notes, you may wish to try the Twiddler in your
non-writing hand.
2. Does your normal computer work involve fine control of the pointing device (such
as CAD or drawing programs)?
If so, you may want to use the Twiddler in the hand that has the best drawing control.
In any case, you may wish to experiment with each hand to see which suits you best.
It is always easy to change the strap to the other side. The Twiddler key layout is
designed to work equally well in either hand.
How to hold the Twiddler
How you hold the Twiddler is a matter of personal taste. It is designed to accommodate
a wide range of hand sizes and shapes. The following guidelines may help you find a
comfortable position:
In general, the strap goes around the back part of your hand, between your knuckles and
wrist, and attaches to the Velcro fastener on the bottom of the case. Do not make the strap
