I think you'll find that the short-term memory item number is closer to 7-8
items. 8-digit telephone numbers are pushing the limit.

Using words can be a way of allowing you to remember more data. As a quick
demo how long does it take you to memorise the phone number:


Now how much easier is it to remember:


- where each letter is mapped to a number via your telephone keypad.

Memory tricksters take this concept even further e.g. by using the brain's
word-association abilities to map a story onto the sequence of cards in a
deck of cards.

A book that I have recommended previously for those interested in the design
of man-machine interfaces was written by Alan Cooper (the "Father of Visual
Basic"). It is titled "The Inmates are Running the Asylum - Why High-Tech
Products Drive Us Crazy and How to Restore the Sanity" ISBN
0-672-31649-8 Sams Publishing.

I also recommend "The Zen of Palm - Designing products for Palm OS". I can
no longer find its original location but a Google search will find copies
for you,
