[comp.human-factors] Good ATM interface

norton@manta.NOSC.MIL (LT Scott A. Norton, USN) (06/22/91)

Last month, I used my ATM card over the Cirrus network to get some
cash while at an airport, far away from my home bank.  I was
worried because I needed the cash, and I had never used the network
before.

After I inserted the card and entered the PIN, I was very pleased
when the ATM showed "Welcome to the XYZ Cash Machine, A. Scott Norton"
Becuase the machine said my name, I was immediatly assured that it
was progressing along correctly on the transaction.

In retrospect, I would guess the machine probably got the name from the
cards stripe, but the heartening effect was real.

On the down side, after the machine used my name for the fifth time,
it just got annoying, like a bad mail-merge form letter.

The lesson for user-interface designers is that substantive feedback like 
this has a real positive effect, particularly on an apprehensive user.

About half of the ATM machines I have used insist on referring to me as A Bruce
Carter (A is my middle initial).  This is mildly annoying since I think of
myself as THE Bruce Carter... :-{)

There's a technical problem with doing this.  Not all card issuers store
the card owner's name in the same format.  Some don't put it on the
mag-strip at all.  With a different card, you might have seen "Welcome to
the XYZ Cash Machine, Norton, A.  Scott", which is somewhat less friendly,
or even "...  Norton Scott", which is wrong.

A few random constraints:

*  Uniformity.  ATMs are increasingly tied together by multibank,
   interstate networks.  It is desirable not only to offer some
   uniformity, but also to avoid sticking in the fork of "enhancements"
   and twirling thousands of lines of code into spaghetti.

   There are also mechanical compatibility issues.  If they all look
   more or less alike they're cheaper.

*  User skills.  Anybody bright enough to walk around unescorted and
   open a bank account might try to use an ATM.  Hence the emphasis
   on function buttons and prompts rather than ASCII input and menus.

*  Mechanical issues.  These machines take a beating.  At any given
   bogey value of cost, that limits how much you can offer and the
   technology with which you can implement it.

*  Psychology.  People are suspicious and conservative about money
   and want reassurance that the machine in the wall is doing 
   something familiar with it.
