Apple tech could help you use your iPhone while in motion

Trying to tap a precise spot
on your iPhone while you're
walking, jogging, or riding in
a car can be a challenge.
Apple may have a solution in
the works via a new patent.
Awarded to Apple by the US
Patent and Trademark Office
on Tuesday, a patent dubbed
" Variable device graphical
user interface " envisions an
interface that changes and
adapts in response to your
movement. The goal is to
enlarge or adjust certain on-
screen elements so they're
easier to tap while you're on
the go.
Accelerometers, gyroscopes,
and other sensors would
detect your motion to try to
determine if you're walking,
running, or in a car. Icons and
other elements on the screen
then would change depending
on the type and severity of
your motion and the phone's
position.
The entries in your contact list
may grow larger so you can
more easily tap on a specific
name. The confirmation box
that appears when a call
comes in could offer bigger
"Yes" and "No" buttons for
you to tap. A "fisheye" effect
also could be used to enlarge
specific elements on the
screen while shrinking the
surrounding area.
A technology that makes it
easier to tap keys while in
motion sounds fine. But what
our phones really need is a
way to tell when they're in
our pockets so we can avoid
the embarrassment of pocket
dialing.
