T-Cube v1.0

August 12, 1994

Designed by: Dan Venolia (dvenolia@apple.com) & Forrest Neiberg

Newton Port: Les Vogel

T-Cube is a new way of entering characters and text on Newton. It

complements handwriting recognition and the soft keyboard. Characters

correspond to "flick" gestures made into the T-Cube window.

After you have installed T-Cube, it is accessed by tapping its button in

the Note Pad status bar. T-Cube shows nine buttons arranged like a wheel.

Pressing and holding the pen down in any of the button shows a different

"pie menu" containing eight characters. You can "type" a character by

moving the pen in one of the eight directions, then lifting it.

This sounds like a tedious way to type, but as you start to memorize common

characters, such as space and "e", you can make the gesture directly,

without invoking the pie menu. Using the menu, an "e" is made by pressing

in the "north" button and dragging to the north-east. As a gesture, this

is a simple flick that starts in the north button and proceeds to the

north-east. You should have the most common characters memorized after

only an hour of use.

More information on the design of T-Cube can be found in:

Alphabet," in Proceedings of CHI '94 (Boston, April 24-28, 1994), ACM
