Design Dilemma
|
|
|
|
The comfort of a good fit between man and machines seems largely
|
|
absent in the technology of the information age. Consider the digital
|
|
wristwatch: people generally care less about knowing the time to the
|
|
nanosecond than about seeing how long they've got until lunch. Some
|
|
experts say the solution to this predicament is user-centered design.
|
|
Elementary as that sounds, it could drastically revamp American
|
|
business. (SOURCE: "The Complexity Problem," John Sedgewick, The
|
|
Atlantic, March 1993, p.96)

The Art of Programming
|
|
|
|
A program should be light and agile, it's subroutines connected like a
|
|
string of pearls. The spirit and intent of the program should be
|
|
retained throughout. There should be neither too little nor too much,
|
|
neither needless loops nor useless variables, neither lack of
|
|
structure nor overwhelming rigidity.
|
|
|
|
A program should follow 'The Law of Least Astonishment.' What is this
|
|
law? It is simply that the program should always respond to the user
|
|
in the way that astonishes him least.
|
|
|
|
A program, no matter how complex, should act as a single unit. The
|
|
program should be directed by the logic within rather than by outward
|
|
appearances.
|
|
|
|
If the program fails in these requirements, it will be in a state of
|
|
disorder and confusion. The only way to correct this is to rewrite the
|
|
program.

It's No Secret
|
|
|
|
Three years ago, Mitch Kapor stood up at Esther Dyson's conference and
|
|
spoke about the "secret shame" of the PC industry: PCs were too hard
|
|
to use, and none of us was willing to admit it. Mitch was right. We
|
|
were all participating in a shameful scam - pretending that computers
|
|
were easy to use when most of us knew differently from personal
|
|
experience. ("The Secret Shame of Client/Server Development,"

How To Really Screw Things Up
|
|
|
|
According to the book _The Design of Everyday Things_ by Donald A.
|
|
Norman (see B&B Bookshelf), here's how to really mess up a system
|
|
design:
|
|
|
|
MAKE THINGS INVISIBLE. Don't let the user know what operation to do,
|
|
and don't offer feedback. Do not provide a help function.
|
|
BE ARBITRARY. Pick command names and user actions that don't make
|
|
intuitive sense. See how many alt-shift-cntl-PFkey functions you can
|
|
come up with. Be creative. Neatness does not count.
|
|
BE INCONSISTENT. Use a bunch of different rules. Create inconsistency
|
|
in the way things are done in different modes.
|
|
MAKE OPERATIONS UNINTELLIGIBLE. Use unusual language, abbreviations,
|
|
and cryptic error messages. ("One item could not be deleted because it
|
|
was missing." - Mac System 7.0b1 error message)
|
|
BE IMPOLITE. Treat users like the pond scum you know they are.
|
|
MAKE OPERATIONS DANGEROUS. Make it easy to destroy important work. Do
|
|
*not* provide an undo function.
|
|
|
|
On the other hand, if good design is considered a plus at your shop,
|
|
the following qualities may be desirable:
|
|
|
|
VISIBILITY. Tell the users what's going on and what their options are.
|
|
A GOOD CONCEPTUAL MODEL. Try thinking about the problem at hand for a
|
|
while *before* you start to code. Talk to the users about the process
|
|
you are trying to codify.
|
|
GOOD MAPPINGS. Users can help determine the relationship between
|
|
actions and results; controls and effects; and the system state and
|
|
what is visible on-screen. Yes, the user is your *friend*.
|
|
FEEDBACK. Let the users know the results of their actions.
|
|
GOOD ERROR HANDLING. "If an error is possible, someone will make it.
|
|
The designer must assume that all possible errors will occur and
|
|
design so as to minimize the chance of error in the first place, or
|
|
its effects once it gets made. Errors should be easy to detect, they
|
|
should have minimal consequences, and, if possible, their effects
|
|
should be reversible." (Donald Norman)

Mainframe Continues Its Death Throes
|
|
|
|
Forrester Research, Inc. has released a report entitled _The
|
|
Mainframe's Fate_, which concludes that mainframe computers, once the
|
|
mainstay of corporate computing, are slowly fading into irrelevance.
|
|
Despite what diehard 'big iron' supporters may say, as the world moves
|
|
to client/server computing, distributed computing and smaller, cheaper
|
|
hardware, mainframes will put out to pasture. In fact, some already
|
|
have been and many more will follow. Of the fifty Fortune 500
|
|
companies surveyed, 10% had already pulled the plug on their
|
|
mainframes, and another 18% were actively seeking to reduce their
|
|
dependence on mainframes. The report does not, however predict the
|
|
mainframe's extinction any time soon. It will continue to see some use
|
|
as a central data warehouse. However, a new class of corporate servers
|
|
will emerge using the most powerful of today's processors, in many
|
|
cases using multiple processors. These will probably pound the final
|
|
nail in the coffin and bring to end the stone ages of the Information
|
|
Age. (SOURCE: Newsbytes 8/5/93)

Kick Them While They're Down Department
|
|

+BLUE LIGHT SPECIAL. Here's a little more information on the new laser
|
|
from IBM (B&B v1#4). The blue light laser based system could put 6.5
|
|
gigabytes on a 5-1/2 inch optical disk. This is 5 times the density of
|
|
current devices. IBM scientists hope to have a commercial version of
|
|
this technology in 4 or 5 years. (SOURCE: Computerworld 8/9/93, p. 31)
|
|
|
|
+NEWTON IS HERE. I would be remiss if I did not mention that Apple's
|
|
Newton Message Pad is out at last. The verdict is not in yet - I have
|
|
seen both glowing praise and less than wonderful reviews of the most
|
|
prominent of a new breed of personal digital assistants (PDAs). The
|
|
$700 package learns to read your handwriting, will automatically add
|
|
an appointment to your calendar based on a note, or dial a phone or
|
|
send a fax. Future versions will feature wireless messaging
|
|
capabilities. Currently Newtons can talk to each other via infrared
|
|
links. Third party manufacturers will be providing add-on products and
|
|
software to extend the Newton Pad's functionality. Keeping in mind
|
|
that these devices are in their infancy, I expect to see Artificial
|
|
Intelligence techniques applied to these gizmos, making them true
|
|
personal assistants in the future, capable of initiating actions with
|
|
minimal input from the user. For example, the head office schedules an
|
|
important out of town meeting at the last minute . Your PDA sees it is
|
|
a priority one event. It books a plane flight, adding the flight
|
|
information to your calendar, informs the office via email that you
|
|
won't be at the office tomorrow, reschedules meetings by sending
|
|
participants a message, perhaps checking with their PDAs for a
|
|
convenient time, and updates your schedule accordingly. For us more
|
|
academic types, PDAs will initiate searches for citations or other
|
|
pieces of information needed from the networks. More on PDAs and
|
|
intelligent agent technology in an upcoming B&B ONLINE.
|
|
|
|
+THE MOTHER OF ALL STORAGE DEVICES. A commercial patent has been
|
|
granted to EMASS corporation, for a technology that can store up to
|
|
10,000 terabytes of computer data in a device called the DataLibrary
|
|
archive. A terabyte is one trillion bytes, or the equivalent of about
|
|
500 billion pages of text. For those with more modest storage needs
|
|
the company plans to offer the Data Tower archive, a phone booth-sized
|
|
structure that stores 6 terabytes of data. The high-speed ER90 tape
|
|
drive can operate at 15 megabytes per second, and the D2 DataCassettes
|
|
store up to 25 gigabytes on a VHS-size cassette. Mind you, the
|
|
machines are not ready to ship yet, and the technology is not cheap.
|
|
A six terabyte system will cost over $1 million, depending on the
|
|
configuration of the system. (CONTACT: EMASS Systems, 214/272-0515,

+VR FOR THE MASSES. Sega will be releasing the first mass market
|
|
virtual reality product in time for Christmas gift-giving. The Sega
|
|
Virtual Reality Stuntmaster, a combination goggle/headphone add-on for
|
|
the Sega Genesis game system, will retail for about $200. It
|
|
comes with a game called "Nuclear Rush," that will put users in the
|
|
middle of the action, with 360-degree stereoscopic view and realistic
|
|
sound placement - you'll be able to hear them gaining on you.

+FREE EMAIL SYSTEM. Pegasus Mail, or PMail, is a native Novell Inc.
|
|
Message Handling Service (MHS) mailer that does not require Novell's
|
|
MHS to run. It runs on the PC and MacIntosh platforms. The program's
|
|
developer, David Harris, first released PMail in 1990, and currently
|
|
supports the product over the Internet with the aid of the PMail
|
|
User's Group. Though the program is free, Harris sells licensees to
|
|
make unlimited copies of the manual for $275 "to cover development
|
|
costs." The article I am reading goes on to quote enthusiastic users
|
|
who say the package is better than many commercial offerings. Users
|
|
include the state government of Minnesota, the Department of Defense/
|
|
Navy at Charleston SC, Cambridge Systematics in Cambridge MA, and
|
|
Alberta Power, Ltd. Version 3.0 is due out this month.

+MICKEY MOUSE GOES ONLINE... The Walt Disney Co. took its first small
|
|
step online, as its Disney Adventures magazine signed to make the
|
|
publication available through the America Online service. They join
|
|
Time Magazine (B&Bv1#4), WIRED Magazine (B&Bv1#3), Cable News Network,
|
|
The San Jose Mercury News, and Knight-Ridder and Tribune newspapers,
|
|
all of which have or will soon have online versions on America Online.
|
|
Industry analysts predict that major media companies like Disney and
|
|
Time Inc. will be major players as content providers to the online
|
|
market in coming years. Alliances with existing online companies are
|
|
the first step toward reaching this growing market. In a related
|
|
story, Disney Computer Software has also entered into a three-way
|
|
alliance with Sega Enterprises and Virgin Games to develope movie-
|
|
based game software for Sega's pocket game machine. The first product,
|
|
due in October, is a game version of Aladdin, Disney's hit movie, and
|
|
will feature high resolution, fast moving animation at a rate of 60
|
|
screens per second. This is more than twice the speed of a television
|
|
or a movie. Disney animators will provide the animation.

Highway To A Wasteland?
|
|
|
|
Will the cost of the much ballyhooed data superhighway - as much as
|
|
$25 billion - encourage the risk-sharing alliances of cable, computer,
|
|
and telephone companies to try to recoup their investment by focusing
|
|
entirely on sales of movies, home shopping, and interactive games at
|
|
the expense of consumer control? "Unless some social or public
|
|
interest goals are established now, I'm afraid this information
|
|
superhighway will simply end up deepening the ocean of
|
|
commercialization that we have fallen into," says Berkeley journalism
|
|
professor Ben Bagdikian. ("What So Proudly We Logged On," Tom Abate,

IRS Employees Caught With Their Hands In The Electronic Cookie Jar
|
|
|
|
An internal IRS report reveals that almost 370 IRS employees at the
|
|
regional headquarters in Atlanta have been snooping into taxpayer
|
|
records - just for kicks. They were examining the personal tax records
|
|
of friends, enemies, neighbors, and even celebrities without agency
|
|
authorization. The more ambitious ones even set up a side-line
|
|
altering reports which resulted in lower tax obligations in exchange
|
|
for payments. Many civil-liberties concerns have been raised over the
|
|
move to provide more information online so government agents and the
|
|
public can quickly access more information. Not surprisingly, it looks
|
|
as if these groups are right to be concerned. Nearly half of the more
|
|
than 100-thousand IRS employees currently have access to these files,
|
|
and if the same pattern applies to the other regional offices, it is
|
|
possible that more than 1,000 IRS employees may be routinely be
|
|
looking at private records. Sen. John Glenn (D- Ohio), chairman of
|
|
the Senate Governmental Affairs Committee, is calling for an expanded
|
|
investigation. Two employees have already been indicted, and as many
|
|
as 80 others are under investigation for possible criminal
|
|
prosecution. (SOURCES: E-D-U-P-A-G-E 8/5/93, Newsbytes 8/3/93,

======================================================================
|
|
SIGGRAPH '93, the premier conference on computer graphics and
|
|
interactive techniques, has come and gone, and from the sound of it,
|
|
it was a doozy this year, with an emphasis on interactivity and not
|
|
a little weirdness, which is enough right there to give it the B&B
|
|
seal of approval. Held near Disneyland in sunny Anaheim, California,
|
|
games, entertainment, and education were the themes of the show.
|
|
Highlights included:
|
|
|
|
- The Silicon Graphics exhibit, inspired by the movie Jurassic Park,
|
|
which gave show goers a chance to enter a giant box and climb into a
|
|
saddled teradactyl. Of the groups who entered the box only three were
|
|
allowed to actually ride, but onlookers saw the virtual scene as well.
|
|
|
|
- Evens and Sutherland offered a chance to take a virtual hang-glider
|
|
ride through a crowded city-scape. Participants were helped into
|
|
body-length slings that hung them suspended in front of a viewing
|
|
screen. They controlled their movement through the space via a hang-
|
|
glider bar they grasped with both hands. Stereo speakers provided the
|
|
sound. Riders reported that the sensation of hang-gliding was very
|
|
real despite the comic book appearance of the city landscape through
|
|
which they flew.
|
|
|
|
- In the electronic art area, sinners of all denominations could stop
|
|
in at an electronic confessional. Based on the confessions of the
|
|
Catholic church, the automated religion kiosk, called "Catholic Turing
|
|
Test" by Gregory P. Garvey, was a thin, shiny, black plastic structure
|
|
with a red neon cross at the top and a red kneeling bench in front.
|
|
The program started by asking how long it had been since you'd last
|
|
been to confession (answers were typed in). Sins were then selected
|
|
from a menu and penitents were told at the end of the confession what
|
|
type of sins they were and how many "Hail Marys" were needed for
|
|
penance. I swear I'm not making this up.
|
|
|
|
- At a group of tables, show goers who sat down to relax were
|
|
eventually bumped and mumbled at by what appeared to be a giant
|
|
bowling ball. Called "Adelbrecht" by designer Martin Spanjaard, the
|
|
mobile robot moved around under its own power, bumping into chairs and
|
|
people, changing direction all the while making beeping and whirring
|
|
noises, and mumbling unintelligible speech to show goers.
|
|
|
|
- The "Neuro Baby" was a monitor in a crib that displayed a pink,
|
|
cartoonish, buggy-eyed "baby" face that bounced around on the screen
|
|
and responded to attendees who bent down to speak into a microphone by
|
|
the crib. The baby laughed, cried, said "Hi," rolled its eyes, and
|
|
even got red-faced mad when the Newsbytes reporter laughed at it.
|
|
The voice analysis was performed by a neural network emulator that
|
|
converted voice input into "emotional" patterns to which the computer
|
|
had been "taught" to respond. A Silicon Graphics Iris 4D was used to
|
|
generate the image of the baby.
|
|
|
|
There were also lectures and conferences and a well stocked job
|
|
postings board to be found at SIGGRAPH. The keynote speaker was Trip
|
|
Hawkins, president, chief executive officer (CEO) of 3DO, and chairman
|
|
of computer game maker Electronic Arts. SIGGRAPH '94 has been announced
|
|
for July 24-29 at the Orange County Convention Center in Orlando, Florida.

- Two books that belong on every designer's shelf. In a world of VCRs

Norman explains how to design things that work *with* human nature

instead of against it as so many objects and programs do. Filled with

many amusing anecdotes we can all relate to, these books entertain
|
|
and teach good design principles. The second book is more computer-

celebrates human foibles: "A machine is not distractible: My computer

will continue doing its job even as the building burns down... We

might rejoice in the fact that people are attentive to their
