the button on top of the mouse. The mouse is designed to sit under one hand of the user and detect
movement relative to its two-dimensional supporting
surface. The mouse senses our motion and clicks
and sends a signal to the computer so it can respond appropriately.

First Mouse
Dr. Douglas Engelbart invented the
first mouse in 1963. It was called
the mouse because the early
models had a cord attached to the
rear part of the device.

The computer mouse is an input device that helps
one operate the computer. People naturally point
at things with their index finger, and the mouse
uses the same concept. When you want to activate
something in the computer, you simply move the
cursor over the item you want to activate and click

Douglas Engelbart of Stanford Research Institute invented the computer
mouse in 1963 after extensive usability
testing; however, the mouse was ahead
of its time. The mouse did not become
a success until the introduction of the
Apple Macintosh computer and the
success of Microsoft’s Windows
operating system. The first mouse, a
bulky device used two gear-wheels
perpendicular to each other: the rotation
of each wheel translated into motion
along one axis. Engelbart received a
patent for the wooden shell with two
metal wheels (computer mouse U.S.
patent #3,541,541) in 1970, describing
it as an “X-Y position indicator for the
display system.”
Optical Mouse
Developed by Agilent Technologies
and introduced to the world in late 1999,
the optical mouse actually uses a tiny
camera to take thousands of pictures
every second. The optical mouse uses
a small, red light-emitting diode (LED)
that bounces light off that surface onto
a complementary metal-oxide semiconductor (CMOS) sensor. The CMOS
sensor sends each image to a digital
signal processor (DSP) for analysis.
The DSP detects patterns in the images
and determines how far the mouse has
moved and sends the corresponding
coordinates to the computer. The computer moves the cursor on the screen
based on the coordinates received from
the mouse. Unlike the mechanical mice
which requires a mouse pad, the optical
mouse can operate on almost any
surface. It also runs smoother, and
requires no cleaning.

Bill English invented the so-called
“ball mouse” in the early 1970s while
working for Xerox PARC. The ball mouse
replaced the external wheels with a
single ball that could rotate in any
direction. The ball’s motion, in turn, was
detected using perpendicular wheels
housed inside the mouse’s body. This
variant of the mouse resembled an
inverted trackball and was the predominant form used with personal computers
throughout the 1980s and 1990s.

Wireless Mouse
Most wireless mice use radio frequency
(RF) technology to communicate
information to your computer. Being
radio-based, RF devices require two
main components: a transmitter and a
receiver. The transmitter is housed in
the mouse. It sends a electromagnetic
signal that encodes the movement of
the mouse and the buttons you click.
The receiver, which is connected to the
computer, accepts the signal, decodes
it and passes it on to the mouse driver
software and your computer.
Digital–Analog Design Punch Cards is a set of research cards designed
and produced by the students of DSGD 186, Digital Applications
Methodology, a third-year graphic design course at San Jose State
University, Fall 2006. The set, composed of 1+26 cards, is by no means
complete. Each topic was chosen and researched by the students,
based on a theme presented by the instructor Pino Trogu, with help
from Mauro Panzeri. This is card number 17 and it was designed by
Eric Feng.

This is an alternate type of input device
that can be used in place of, or in
conjunction with, a mouse, trackball, or
other pointing device. It allows one to
hand-draw images and graphics, similar
to the way one draws images with a
pencil and paper. Graphic tablets
consist of a flat surface upon which
the user may “draw” an image using
an attached stylus, a pen-like drawing
apparatus. The image generally does
not appear on the tablet itself but, rather,
is displayed on the computer monitor.
Graphics tablet is great for graphic artist
because it has pressure-sensitivity. This
means the flat surface can sense the
pressure one draws on the tablet, so it is
great for creating computer graphics.
