Here's an approach to Morse code on iPhones that might prove better for text input than the current scheme.


A Morse interface would use a well-established ‘open source’ standard—International Morse Code. Dots are input by short swipes. Dashes by long swipes.

Speed of input doesn't matter. Letters are distinguished by alternating swiping right/left and then up/down. (A user-set delay inputs the last character, i.e. one not followed by a swipe in a different direction.)

Lowercase letters are made by swiping left-to-right or up-to-down.

Uppercase letters are made by swiping right-to-left or down-to-up.

Alternately, two-finger swipes could be used for uppercase.

Swipe mode changes when the user rotates the screen.

Common punctuation uses diagonal swipes, i.e. upper-left to lower-right for a space, lower-left to upper-right for a period or a period plus space.

Circling CCW might delete the previous character. Circling CW might enter a Return. Alternately, a short shake of the iPhone deletes the previous letter, while a longer shake deletes the previous word.

Touching the keyboard with another finger, perhaps the thumb in the lower-left corner for right-handed people, might signify something. It might bring up a scrolling list of long text strings (i.e. a phone number or address) from which the user could select.

In learner mode, the screen would display the Morse alphabet and text input would be on a scrolling line. Letters or words could be spoken as typed.
For those willing to learn Morse, it offers a fast, virtually error-free text interface for the iPhone, one that has tactile feedback built into the design. For most European languages, it takes advantage of the fact that Morse code is already optimized for speed. A short swipe is an “e,� and a longer swipe is a “t.� Most important of all, it’s a text input technique that doesn’t require them to constantly look at the screen. Since the target is the entire screen, it’s impossible to miss.

Fee free to use this idea or pass it on.
