Twiddler2 Model HKT2-16 - Reg. U.S. Patent Office

MADE IN USA

ETTIN STARTED

Overview

The Twiddler2 provides the sa e input to

your co puter as both a conventional keyboard and a

ouse. To do this the Twiddler2 uses twelve keys on

the front and, on top, four keys plus an IBM

Trackpoint®. The top keys are for your thu b; your

other four fingers operate the front keys; and the red

Trackpoint under your thu b perfor s the pointing

function of a ouse. The Twiddler2 is designed to be

operated by only one hand. The hand not holding the

Twiddler2 is free for other tasks (like holding a tele-

phone or a cup, keeping your place when typing a list,

jotting a note on paper, etc.)

The Strap

There is a soft fabric strap that extends fro a

slot in the side of the Twiddler2's case and attaches to

a Velcro®pad on the botto . This strap goes around

the back of your hand and holds the Twiddler2 in posi-

tion for typing or pointing. When you receive your

Twiddler2, the strap will be set up for right-hand use,

but it ay be easily readjusted for left-hand use.

Changing to Left-Hand Use

To adjust the Twiddler2 for left-hand use, first

re ove the strap fro its Velcro fastener on the botto .

How to ho d the Twidd er2

How you hold the Twiddler2 is a atter of per-

sonal taste. It is designed to acco odate a wide

range of hand sizes and shapes. The following guide-

lines ay help you find a co fortable 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 botto of the

case. (Check the photo on the back cover for strap

place ent.) Do not ake the strap too tight. You should

adjust the strap so your fingers fall naturally and easily

over the center colu n of keys (the keys with the s all

guide-bu ps on the ).

You will notice that your thu b is resting on the

top inside corner of the Twiddler2. When the strap is

adjusted correctly, it is loose enough so that your hand

can be re oved and re-inserted without detaching the

strap fro the Velcro. Rotating the Twiddler2 toward or

away fro your pal adjusts the angle of operation to

acco odate longer or shorter fingers; and the angle

of the strap on the botto of the Twiddler2 can also be

adjusted for your co fort. In fact, one way to find a

co fortable position is to re ove the strap fro the

botto , set the Twiddler2's angle, and then re-attach

the strap to the Velcro pad. The fastener on the botto

helps to hold the desired angle of the

Twiddler2.

When you have adjusted the strap and angle

so that your fingers fall naturally over the center col-

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 sa e fitted end of the strap into

the atching slot on the opposite side of the

Twiddler2. Be sure to insert it all the way into the slot.

Getting Started: Left or Right?

Which hand should you use for the Twiddler2?

The first inclination is to use it in your do inant

hand. But you ay wish to put off this decision and try

the Twiddler2 with each hand and think about how you

will be using it before you decide.

Here are a few things to consider:

What do you want to be able to do with the

hand not holding the Twiddler2?

If you want to take pencil-and-paper notes, you

ay wish to try the Twiddler2 in your non-writing hand.

Does your normal computer work involve fine

control of the pointing device (such as CAD or drawing

programs ?

If so, you ay want to use the Twiddler2 in the

hand that has the best drawing control. In any case,

you ay wish to experi ent with each hand to see

which suits you best. It is always easy to change the

strap to the other side. The Twiddler2 key layout is

designed to work equally well in either hand.

able chords. And, since ost of these key co bina-

tions are not preset at the factory, you can custo ize

your Twiddler2 by aking your own assign ents to

these chords. You can even override factory-preset

key/chord/character assign ents. Custo chording is

explained in the section on Interactive Programming.

TYPIN ON THE TWIDDLER2

Sing e Keys

There are twelve keys on the front of the

Twiddler2 arranged in three colu ns and four rows.

Each key in the center colu n has a tiny bu p which

akes touch-typing easier by letting you know i edi-

ately, by touch, which key your finger is pressing.

Each of your fingers is assigned to a specific

row of three keys across. Your index finger presses the

keys arked A, E, and SP (space) in the first or top

row. Use your iddle finger to press B, F, and DEL

(delete) in the second row. Your third (ring) finger is for

the C, G, and BS (backspace) keys in the third row.

And your little finger (pinkie) is in position for the keys in

the fourth or botto row--D, H, and ENT (enter). Press

and release any of these keys singly to type the charac-

ter or co and with which the top of the key is labeled.

u n, you will find that the left and right colu ns of keys

are an equally short reach for your fingers. If the strap

is too tight, the closest colu n ay cra p your

fingers. If the strap is too loose, the colu n farther

away ay be hard to reach.

You can comfortably rest your thumb on the inside

corner of the Twiddler2, in a relaxed position, as

shown in the photograph on the back cover.

You don't need to grip the Twiddler2. By resting the

thu b as shown, and applying gentle outward pres-

sure, you will keep the Twiddler2 steady and reach the

keys ore easily.

THE KEYBOARD

The Twiddler2 keyboard is designed to do all

the work of a standard co puter keyboard plus a lot

ore. With only sixteen keys, the Twiddler2 acco -

plishes this by chording.

On a piano keyboard you can play a single note

by striking one key or play a chord by playing a nu ber

of keys at the sa e ti e. The Twiddler2 works in a si -

ilar way. You can type a character or co and with a

single key or with a co bination of keys called a chord.

Using various single keystrokes or chords, you can type

all the letters, characters, sy bols and co ands

found on a standard keyboard. In fact, the Twiddler2

actually offers you over a thousand different progra -

Key Notation

This user's guide uses a special notation to

show you how to type each character and co and

with a factory-preset chord. As you face Twiddler2's

twelve-key layout, you will find four keys (labeled SP,

DEL, BS, and ENT) arranged in a colu n on the left.

This colu n is designated L. The four keys in the

iddle colu n (E, F, G, H) are referred to as M. And

the four keys on the right (A, B, C, D) are designated

R.

Each unique chord is defined by a four-sy bol

sequence indicating which key is pressed in each of the

four rows ordered fro top to botto . If no key needs

to be pressed in a particular row, a zero (0) in the

sequence will indicate that. Re e ber that the first

sy bol in the chord notation refers to a key in the top

row pressed by your index finger, the second sy bol to

a key in the second row assigned to your iddle finger,

the third sy bol to a key in the third row pressed by

your ring finger, and the fourth sy bol to a key in the

botto row reached by your little finger. (See the box,

Finger Key Notation)

For exa ple, to type a lowercase letter a, your

index finger ust press and release the key at the right

end of the top row, while no other keys need to be

pressed in the next three rows. So the notation for ais

R000.

Chords

The Twiddler2 does not register a keystroke until you

release a key or keys. For exa ple, when you press

the Akey on the Twiddler2 and hold it down, nothing

happens. But when you release the Akey, a lowercase

letter aappears on the screen. When you press a

group of keys as a chord, its assigned character does

not appear on the screen (or its assigned co and is

not issued) until you release at least one of the chord's

keys. Because characters are generated by the release

rather than the initial press of a key, you do not have to

worry about whether you have pressed all the keys in a

chord at exactly the sa e instant.

Repeating Keys

On a standard keyboard, when you hold down

a key it generates a repeating character. To repeat

characters in the sa e way on the Twiddler2, press and

release a key or chord and then quickly press and hold

down the sa e key or chord. When you do this the

desired character will repeat as long as the key or

chord is held down.

Si ilarly, you can type the lowercase letter kby

pressing and releasing (with your index finger) the left key

in the top row, no keys in the next two rows, and (with your

little finger) the right key in the botto row. This chord is

designated by the notation L00R.

FINGER KEYS are indicated

by a group of four symbo s:

0, L, M, and R.

These symbols repre-

sent key presses in OWS 1,

2, 3, and 4 (top to bottom). 0

means no button pressed in

that row; L means the Left

button is pressed; M means

the Middle button is pressed;

and, means the ight button

is pressed.

Example:

L00 means the

LEFT Button in OW 1 and

the IGHT button in OW 4

are pressed. No buttons are

pressed in OW 2 or OW 3.

The example given

L00 is the notation for typ-

ing the letter k.

Finger Key Notation

Labe s

Black, red, blue, and green labels on

Twiddler2's keys can re ind you how to type the ost

co on characters and co ands.

A black label on a key refers to the character or

co and you type when you press and release that

key alone. To type a lowercase a, you press and

release the key labeled with a black A. To type a lower-

case b, press and release the key labeled B; and so on

for keys labeled C, D, E, F, G, and H. Si ilarly, keys

arked SP (space), DEL (delete), BS, (backspace), and

ENT (enter) issue the designated co and when

pressed and released singly.

You will find a colored dot above each top row

key. Red arks the top left key; blue arks the top

iddle key; and green arks the top right key. To the

right of each key in the re aining three rows you will

find a colu n of three labels whose colors--red, blue,

and green--correspond with the colors of the top row

dots. Matching colors indicate a dotted-key/labeled-key

chord which types the labeled character.

For exa ple, press the left key in the top row

under the red dot and the right key in the next row

beside the red label I. When you release the two keys

you have typed the lowercase letter i. Note that the

label I is red to re ind you that the red-dotted top row

pappeared when you released your ring finger.) Now

use your iddle finger to press and release the right-

hand key in the second row. (Note that it is next to the

red label I.) You just typed a lowercase i(LR00).

Again, keeping the red-dotted key down, release your

iddle finger fro the second row and reach with your

little finger for the iddle key in the botto row (labeled

with the red N) to for the chord for lowercase n

(L00M).

Finally, release both top and botto keys. This

technique will help you type faster by avoiding unneces-

sary finger ove ents. You can use this with any

co binations of letters: st, ry, in, lo... Can you find

so e others?

Another Speed Tip

The Twiddler2 offers you another typing short-

cut. You can use factory-preset chords to type so e of

the co onest English words or letter sequences:

the, of, to, ed, and, in, ion, and ing. The key nota-

tion for these chords can be found in the Key

ssignment Tables.

key is part of the ichord LR00.

Here is a second exa ple. Press the top row key

under the green dot together with the key in the third

row just to the left of the green excla ation point !.

When you release both keys you have typed an excla-

ation point ! (R0L0).

Re e ber that, after you have pressed all the keys in

a chord, you ay release the together or in any order.

You will find a co plete list of factory-preset letters,

characters, sy bols, and co ands in the Key

ssignment Tables near the end of this guide.

Speed Tip

Here is a tip to speed up the way you type a

series of letters which have chord labels of the sa e

color: Keep holding down the top row key with your

index finger while your other fingers for chord after

chord with keys on the lower rows. Try this exa ple.

Type the word pin.

First press the chord for lowercase p(L0L0)--a

red-labeled chord. Then lift your ring finger fro the

third row while continuing to hold down the red-dotted

key in the top row with your index finger. (Notice that a

Ctrl key on a standard keyboard. To type Ctrl-Alt-Del,

for exa ple, si ply press and release the CTRL key

together with the ALT key and the front key labeled

DEL.

Likewise, the Shift key, as you would expect on

a conventional keyboard, allows you to type capital let-

ters. When you for a chord which includes the Shift

key with your thu b, the sa e key or chord you ordi-

narily use to type a lowercase letter will instead produce

the sa e letter in uppercase.

It is i portant to note, however, that the Shift

key (like all the thu b keys) does not just shift the front

keys to upper case, but fully particpates in the chording

function. For exa ple, the word the is assigned to the

chord 0RR0. If you press Shift + 0RR0, however, you

get The. If the thu b button labelled Shift just shift-

ed characters, you would get THE.

As you read the section on Macros, you will see

that the chording principle is very flexible and allows

assign ent of over a thousand sy bols, functions, or

groups of sy bols or functions to chords.

Thumb Keys

In addition to the red IBM Trackpoint, there are

four keys on the top rear of the Twiddler2 case. In

clockwise order they are labelled NUM, ALT, CTRL,

and Shift. These thu b keys take part in the chording

and co bine with the twelve front keys to for addition-

al chords.

Chords using the NUM key include the nu er-

als. You hold down the NUM key with your thu b and

co plete the chord by pressing additional keys on the

front. To see how it works, try holding down NUM with

your thu b while your other fingers consecutively press

and release the following keys:

A, B, C, D, E, F, G, H, SP, DEL.

You have just typed the nu erals

1, 2, 3, 4, 5, 6, 7, 8, 9, 0.

The ALT key accesses the sa e functions as

an Alt key on a conventional co puter keyboard. For

exa ple, to issue the co and Alt-x, you si ply for a

chord, including the ALT key and pressing and releas-

ing the chord for the letter x(ML00).

When you for chords by holding down NUM

and ALT together, the front keys A, B, C, D, E, F, G, H,

SP, DEL, BS, ENT output the codes for Function keys

F1 through F12.

In si ilar fashion the CTRL key acts like the

The Ckey issues a left-Ctrl-click and the Gkey pro-

vides a left-Shift-click.

By default, the Twiddler2 stays in mouse-

mode indefinitely after you release the mouse but-

ton. (This may be adjusted by the user. See

Interactive Programming, below) This enables you

to position the pointer on the screen, release the

Trackpoint, and then click on an object. With the excep-

tion of two keys (explained below), pressing and releas-

ing any black (thu b or finger) key exits ouse ode

after perfor ing its function.

Here is an exa ple of a co on situation: You

are typing a e o and you wish to insert a word 2

lines above. Press the ouse key and ove the point-

er where you wish to insert the word. Re ove your

thu b fro the ouse pointer and it stays in ouse

ode until you press the "A" key (left-click). This sets

the cursor in the selected location and auto atically

exits ouse ode back to keyboard ode so you can

start typing i ediately.

Exceptions:

The two ouse keys which do not auto atically

exit to keyboard ode are the key arked "E" and the

key arked "F". The "E" key, in ouse ode, signals

left-click-and-stay-in- ouse- ode. The usefulness of

this is when clicking repeatedly on the scroll-bar without

touching the ouse. The "F" key, in ouse ode, sig-

nals iddle-click-and-stay-in- ouse- ode.

THE MOUSE POINTER

The IBM Trackpoint®on the Twiddler2 is your

ouse. Press the red button with your thu b to ove

the pointer on your screen. When you take your thu b

off the Trackpoint, the onscreen pointer stays where it

is.

Mouse-c icking

When you press the Trackpoint, the Twiddler2

goes into ouse- ode. This eans that the front keys

now function as ouse buttons. (I agine a ouse with

12 buttons.) The Akey is now the left ouse button

and the SP key is the right ouse button. Press and

release the Akey to left-click on an onscreen object.

Press and release the SP key to right-click on an

object. The Ekey is also a left click button, with the dif-

ference that it stays in mouse mode after it is released.

When you need to double-click with a left

ouse button you can press and release the Ekey

twice, or si ply press and release the Bkey. This is a

very convenient way to double-click. (Since the Akey

exits ouse ode when it is released, you cant use

this to double click.) If you need to click-and-drag, the

Twiddler2 will e ulate a left ouse button being held

down when you press and release the Dkey. Press D

again to "lift" the virtual left ouse button. Si ilarly, a

right ouse button is virtually "held down" when you

use the ENT key and "lifted" by again pressing ENT.
