CamScanner OCR test

CamScanner is a rather nice scannerapp for phones and tablets. One of the most desirable features for me is the OCR capability. The OCR works well for basic documents with minimal formatting but alas, it is nowhere near as good as what Fujitsu has in the ScanSnap software (which embeds the OCRed text in the PDF and preserves excellent formatting).

Here are the CamScanner results*:

conceptual analogies.

tinat’s because analogy is much more than a
liwistic device : it’s a fundamental way of
thinking-To aiake an analogy is to make a comparison
that suggests parallels between two distinct
things, eJCplicitly or implicitly. And those who are
most nimble at seeing parallels and connections,
rather than just obvious difierences, compete best.

cism, Kiann and Ms cohorts built a moving
assembly line. Within four months, Ford’s line had cut
the time it took to build a Mode1T from 12 hours
per vehicle to just 90 minutes. In short order, the
moving assembly line revolutionized
manufacturing and unlocked trillions of dollars in economic
potentiaJ. And while in retrospect this innovation

wasn’t ; the underlying analogy between moving

Question conventional analosles

Always kick the tires on the analogies you
encounter or consider. Some analogies ring true at first
but fall apart on closer examination. For example,
cennuies of would-be aviators modeled their
machines after birds in an attempt to flap their way
aloft. But flapping had nothing to do with the
intrinsie aerodynamics of flight ; rather, it reflected
challenges of propulsion unique to birds.

The Wright Brothers, by contrast, saw an
analogy to the machine that they already designed,
manufactured and repaired for a living-the
bicycle. Both were unstable vehicles requiring
nuanced balance and control in three dimensions ;
both 811 if they lost too much forward
momentum. The design decisions this analogy inspired

Darwin’s second insight was to dlzw an analogy
between breeding in agricultl. ire and”natural
selection”in the wild. Melding both analogies, he offered
a revolutionary theory that not only explained
biological evolution but also equipped people with a
systematic approach for under standing gradual
change in virtually any complex system.

No matter how seductive an analogy may be, be
sure to examine several others before deciding
which one might be most useful. Usually, more than
one analogy can shed light on a given situation.

Charles Darwin, for example, developed his
theory of evolution based on two fundamental
analogies. The first analogy drew a parallel
between geology and biology. Darwin reasoned that
if a modest, meandering stream could erode
grains of sand one by one to carve a mighty
canyon, perhaps small, random changes in a plant or
animal could influence its relative survival and
reproductive rates over generations, gradually

The art of analogy flows from creative re-
categorization and the information that we extract from
surprising sources. Take the invention of the
moving assembly line. Credit for this breakthrough
typically goes to Henry Ford, but it was actually
the brainchild of a young Ford mechanic named


Similai-ly. Steve Jobs recognized that the digital
“clesktop.”First developed but unappreciated ilt
Xerox PARC, was an analogy that could make
computers accessible to millions of people-an insight he
put to work when he launched the first Mac. That
breakthrough machine (and the innitators that
foltowed) quickly democratized computing and
ushered in today’s information age.

Jobs always pushed for simplicity in design
because, as he used to say, “Simplicity is the
ultimate sophistication.”Thavs how analogies work
too : They make complicated things easier for
people to grasp by stripping them to their essence.
The very best analogies makepthings as simple as
possible-but no simpler.
