[net.graphics] multi-button mouse

vax2:dag (02/14/83)

We here at Fluke have a Scientific Calculations SCI-CARDS printed circuit
board design system that uses Megatek tubes and Summagraphics bit tablet
pointing devices. The puck (not a mouse but same function) has four!!!
buttons on it; SELECT, ZOOM IN, ZOOM OUT, and GRAB FOR PAN. The operators
spend between 10 and 20 hrs/week at the workstations. They seem to get
the hang of multi-button operation quite quickly. After about 3 months
they say they don't ever think about it any more. My conclusion is that
a multi-button mouse is a good idea for heavy use. Less complicated 
arrangements may be better for casual and demonstration use.

In my opinion, in the great world of the future, we will have a one-button
mouse and a multi-key one-handed keyboard that we will learn to type on
with more than one key at a time.  The keyboard will probably have a
thumb operated case shift and eight keys, two rows of four.  That gives
2-d location and 162 physically convenient keypresses plus the mouse
button.  Such an arrangement keeps up from having to let go the mouse
to type and vice-versa.

In my opinion, in the REALLY great world of the future, there won't
be a keyboard at all.  Just voice or brainwaves.

The best multi-key one-handed keyboard I've heard of is the 'chord'
keyboard.  It has 3 rows of 5 keys, and 4 thumb-operated shift keys.
There are 'dimples' (circular indentations) between each pair of adjacent
keys, and in the center of each 4-key cluster.  Pressing a dimple
(which causes a 2 or 4 key cluster to be depressed) has the same effect
as pressing a single key: it generates a single character.  You can
also press several keys or dimples at once, generating a 'chord'.
This causes the characters corresponding to the keys pressed to be
transmitted in sequence.  For example, holding down the index, middle
and ring fingers in their home positions will transmit t-h-e, the most
common word in the English language.  Since the keys and dimples are labeled,
you can type by hunt-and-peck as well as by touch.  A group of motivated
students mastered the chord keyboard in about the same amount of time
as it takes to learn the QWERTY keyboard, and acheived a typing speed
of 40 WPM.  For more information, see IEEE Computer, Dec '78.

Does anyone know if the chord keyboard is commercially available?
