FIRST WORKING MOUSE
Wooden Box Had button on top and two
wheels inside at right angles
Wheels took measurementsby rolling one wheel, whiledragging the other at a rightangle
Calculated the 2-D area

WORKING MOUSE
Information sent tocomputer and shown onscreen as cursor moving
Cord originally attachedto the back got in the way
Switched it to the front

GETTING ITS NAME Engelbart called it the XY
Positioning Indicator
Because it measured the X and Y axisto move the cursor
He thought the public would give it adignified name
A colleague thought it looked like amouse and after that it was referred toas a Mouse.

Same time as Mousedevelopment, other deviceswere being made.
Ex: Knee Switches (top)and Light Pens (bottom)

EXPERIMENTATION
Engelbart received a grantfrom NASA to test andcompare the devices
Wanted to determine whichdevice could do the task thefastest and most accurate

XEROX COMPUTERS Only 100 Alto computers sold
Not a big success
Very slow
Extremely expensive Xerox Star sold for $16,595
Caused Mouse to be
unsuccessful too BUT, they heavily influenced
Microsoft and Apple

EXPENSIVE TO
CHEAP(ER)
Xerox Mice were expensive $350 to $400
Were too complicated for a mass
production Steel ball held in place by metal
assembly
Required exact alignment with rollersand springs to work
Collected dirt from places it rolled on
= bad performance

CHEAPER(ER) Steve Jobs asked design team to
make a mouse that Apple couldsell for $15
Replaced steel ball with
floating lead ball in rubber Made a precision injection-
molded ribcage to hold all
internal mechanics Mouse production became a
cheap, snap-together process

IMPROVING THE MOUSE Went through a variety of shape
changes
From box like to more roundedshape
Needed to accommodate usercomfort

Apples computer manuals containedchapters on how to use the mouse
Needed to convince public it waseasy to use
Slogans: If you can point, you can
