Abstract

As different text input devices lead to different typing error patterns, considering the device characteristics when designing an error correction mechanism can lead to significantly improved results. In this paper, we propose and evaluate a spelling algorithm specifically designed for a five-key chording keyboard. It is based on the maximum a posteriori probability criterion, taking into account a dictionary model and the probabilities that one character is typed for another. These probabilities are determined experimentally. In our experiment, the proposed method reduced the substitution error rate from 7.60% to 1.59%. As comparison, MsWord and iSpell reduced the substitution error rates to 3.12% and 3.94%, respectively.

Electronic keyboard

An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers. Electronic keyboards are capable of recreating a wide range of instrument sounds (piano, Hammond organ, pipe organ, violin, etc.

Keyboard layout

A keyboard layout is any specific physical, visual or functional arrangement of the keys, legends, or key-meaning associations (respectively) of a computer keyboard, mobile phone, or other computer-controlled typographic keyboard. is the actual positioning of keys on a keyboard. is the arrangement of the legends (labels, markings, engravings) that appear on those keys. is the arrangement of the key-meaning association or keyboard mapping, determined in software, of all the keys of a keyboard; it is this (rather than the legends) that determines the actual response to a key press.

Pedal keyboard

A pedalboard (also called a pedal keyboard, pedal clavier, or, with electronic instruments, a bass pedalboard) is a keyboard played with the feet that is usually used to produce the low-pitched bass line of a piece of music. A pedalboard has long, narrow lever-style keys laid out in the same semitone scalar pattern as a manual keyboard, with longer keys for C, D, E, F, G, A and B, and shorter, raised keys for C, D, F, G and A. Training in pedal technique is part of standard organ pedagogy in church music and art music.
