Chording

Chording

Chording means pushing several keys or buttons simultaneously to achieve a result.

Musical keyboards

In music, more than one key are pressed at a time to achieve more complex sounds, or chords.

Computer Keyboards

Chording, with a chorded keyboard or keyer allows one to produce as many characters, as a QWERTY keyboard, but with fewer keys and less motion per finger, and is thought to alleviate[citation needed] or prevent[citation needed] carpal tunnel syndrome.

Pointers

Mouse chording allows a user to use a two-button mouse, trackball, or touchpad as if it where a three-button device. For example, in the Unix graphical user interface (X11), the middle button is used to paste text. Since Microsoft-type mice have only two buttons, users of Unix-type systems such as Linux and BSD chord the right and left buttons to paste text.

Multitouch chording

TipTapSpeech an application for the iPhone and iPad is a chord-based text entry solution for touch screen computing.[1]

A GKOS chording keyboard application development for iPhone was started on the GKOS Google Group [2] on May 25, 2009. The application for iPhone became available on May 8, 2010, and a similar application for Android on October 3, 2010. Thumbs are used to press the keys that are located towards the sides of the screen, either a single key or two keys simultaneously.

Douglas Engelbart, Valerie Landau, Robert Stephenson, Evan Schaffer, Eric Matsuno, and Cherif Algreatly filed a patent in 2010 for a chorded solution for multitouch screens.[3]
