iPhone interface design

The iPhone platform elegantly solves the design problem of small screens by greatly
intensifying the information resolution of each displayed page. Small screens, as on
traditional cell phones, show very little information per screen, which in turn leads
to deep hierarchies of stacked-up thin information--too often leaving users with
"Where am I?" puzzles. Better to have users looking over material adjacent in space
rather than stacked in time.

To do so requires increasing the information resolution of the screen by the hardware
(higher resolution screens) and by screen design (eliminating screen-hogging
computer administrative debris, and distributing information adjacent in space).

This video shows some of the resolution-enhancing methods of the iPhone, along
with a few places for improvements in resolution.

The video is essential to the essay below.
Made in January 2008, using the original iPhone.

In 1994-1995 I designed (while consulting for IBM) screen mock-ups for navigating
through the National Gallery via information kiosks. (The National Gallery had the
good sense not to adopt the proposal.) For several years these screen designs were
handouts in the one-day course in my discussion of interface design, and were then
published in my book Visual Explanations (1997).

The design ideas here include high-resolution touch-screens; minimizing computer
admin debris; spatial distribution of information rather than temporal stacking;
complete integration of text, images, and live video; a flat non-hierarchical
interface; and replacing spacious icons with tight words. The metaphor for the
interface is the information. Thus the iPhone got it mostly right.

Here are pages 146-150 from Visual Explanations (1997):

On the Ask ET forum, we seek to publish questions and contributions that advance the analytical content of the thread, provide a good example, or raise an interesting question. Contributions should be relevant to the chosen thread. Please no marketing pitches, gratuitous links, or incivilities. There are about 6,000 contributions in the 500 threads now published on this board; they provide good examples of what has been accepted for publication.

Some new contributions go to a non-public queue, which is frequently reviewed by a member of the editorial board in order to decide whether the material should be posted. About 30% of submitted contributions are posted; after publication, about half survive the occasional reviews of published items. The editors are unable to reconsider their decisions or to answer any queries about editorial decisions (some of which may well be mistaken). Publication policies are described in detail at Moderating internet forums

If your contribution is published, your email address will be masked on the board, and your identifying IP number will not be published.
