Operating guide for the iGesture Pad and the Retro
If you are not using Windows with your iGesture Pad or
Retro Keyboard you will have to reconfigure
your unit. It only takes a few seconds.
How Does it Work? Your MultiTouch unit consists of
two main components: a Hand Imaging Surface (the touch
surface) and a Gesture Processor. The MultiTouch Gesture
Processor watches the touch surface all the time. It's always
looking to see which fingers are touching and what they are
doing. The Gesture Processor ignores touching and movement
that are not valid gestures or valid typing, so this allows
you to rest your hand on the surface without causing spurious
Interacting with MultiTouch is a form of communication. You
generate gestures and the Gesture Processor reads them and
tries to interpret the meaning of your gestures. You can
easily confuse the Gesture Processor if you don't communicate
clearly - just like you can confuse a careful listener if you
garble your speech. The MultiTouch unit will serve you well if
you communicate with it clearly.
There are five rules that must be followed to ensure clear
communication with your MultiTouch device.
Interacting With Your MultiTouch Device - The Golden
- Touch the surface with the correct number of finger
tips (Note that this applies to only the initial
contact; after the initial contact has been made the
remaining fingers may touch down on the surface)
- Keep the fingers slightly spread - keep them
relaxed not tightly bunched
- Maintain contact with the surface during movement -
relax and let gravity do its job
- Keep the thumb separated from the other fingers
- Finger taps should be light and crisp - don't
bang the keys, save your fingers
Additional information and guidance on each of these rules
is given below.
Rule 1: Touch the surface with the correct number of
finger tips. Clear communication involves touching the
surface with the correct finger tips for the desired
gesture.This is required because each gesture is associated
with a particular set of finger tips that initially touch the
surface. In other words, those finger tips that simultaneously
contact the surface are used to identify the intended gesture.
For example, the mouse operations of point, drag, and scroll
are launched by initial contact of adjacent fingers: two
finger tips initially touching means pointing, three mean
drag, and four mean scroll.
Some of the gestures allow you to drop the non-involved
fingers after initially touching the surface with the correct
(involved) fingers. Practicing this helps to reduce hand
fatique. Note that you do not have to drop the non-involved
fingers but you may find that it is more comfortable if you
do. You can also lift all but one finger without interrupting
the operation you started using more fingers. Here's an
example of pointing using all five fingers.
- Touch any two adjacent fingers on the MultiTouch
- Begin moving fingers in desired direction.
- Drop remaining fingers and thumb onto surface and
Rule 2: Keep the fingers slightly spread - keep them
relaxed not tightly bunched. It's not easy to do,
but it is possible to fool the Gesture Processor into thinking
that one finger is touching the surface when in fact two are.
This can occur if you have small fingers and you squeeze them
so tightly together that they look like one large finger.
Obviously, it isn't your intent to fool your system so relax
your fingers and keep them slightly separated for all
Rule 3: Maintain contact with the surface during
movement. If all your fingers come off the surface
during a gesture operation the Gesture Processor will
interpret that as a signal from you that the operation in
progress has concluded. Relax and let the weight of your hand
keep your fingers on the surface as they slide across it.
Rule 4: Keep the thumb apart from the other
fingers. The Gesture Processor might think that the
thumb is just another finger if it "sees" it in a position
where it should not be. For example, if you put your thumb
right next to your index and middle fingers it may look to the
MultiTouch software like you have touched down three fingers
instead of two fingers and a thumb. Avoid confusing your
MultiTouch unit by keeping the thumb comfortably away from the
Rule 5: Finger taps should be light and crisp. -
Hitting the surface hard with your finger tips is not good
for your fingers. For typing, the Gesture Processor pretty
much ignores how hard you hit the surface and really only
cares how long your finger tip stays on the key you are trying
to type. If you stay too long the Gesture Processor will
assume you are resting your finger and the key will not be
entered. For reliable operation make sure your key taps and
mouse clicks are light and reasonably quick. Practice typing
using the number pad to get the feel of it.
Of course, you don't have to use finger tips to point,
click, drag, and scroll. Knuckles work just as well.
What to Learn First - Using the MultiTouch surface
is very easy. You don't have to learn all the gestures that
the unit recognizes to have fun and to be more productive.
About the only gestures you really have to learn are those
that allow you to point and click, but most people will want
to learn many more.
We suggest you learn the basic mouse
gestures first (i.e., point, click, drag, scroll). These
are very easy and only take a few minutes to learn. The most
difficult thing to remember when using MultiTouch is to stay
relaxed and not be afraid to touch the surface with other
fingers or the whole hand.
You might want to learn the web
browsing gestures next. The back. forward, and scroll
gestures save a lot of effort while the zooming gestures allow
you to change text to a convenient size.These same gestures
are used in many other places such as navigating through
directories or editing documents.
For those that do a lot of document processing you will
find that the editing,
gestures really help to make the process faster and simpler.
Once you learn the gestures you'll never go back to the old
method of moving the pointer to a menu, selecting the
operation, and finally clicking.

enabled/disabled by tapping the NumLock key. The non-numeric
keys of the number pad are enabled/disabled by tapping the

For iGesture Pad users: If you plan to hold the
iGesture Pad in your hand while using it be sure that the
thumb of the hand doing the holding is not touching the
surface. Hold the unit by gripping the plastic enclosure to
prevent touching the surface and thus causing the Pad to think
you are trying to use a new gesture.
