These are a list of the more common terms which apply to use of our Kord Interface Technology, some of which are to be found on this website.
Ambihand Not resolveable as either the right or left hand
BreakChord A chord action that is initiated once all digits have been released
CGUI Chordic Graphical User Interface
Chord One or more digits activating appropriate keys to signal an intent
Chord assignment The mapping of a particular chord or chord sequence to an action. There are numerous competing factors, such as - ease of use, ease of learning, speed of operation and memorability. Consideration must also be given to consumption of the available chord set and the accommodation of new functionality.
Chord shape Shape refers to the structure of the chord, which fingers are pressed. Temporal shape is also considered, how long a chord is held for example.
Chord facility Due to the differences in dexterity between digits of the hand, there is measurable variation in the forming of different chords, and transitions between them.
Chord presentation The visual, audio or other feedback that teaches and informs the user of the available operations. In a visual environment symbols are used to show what to press.
Chord Press The pressing and releasing of one or more digits to form a chord
Chordnomics Concerns itself with the operation of chording human input devices; the interaction between a user and chord shape, presentation, facility and assignment.
Couplet A chord action that requires 2 consecutive chord presses to activate
Digits The fingers or thumb of the user’s hand
Glyph A symbol indicating which digits to press to form a chord
Hand chord value Similar to raw chord value, but also representing the left hand
HoldChord Similar to a Makechord except that a continuing action is implied
Inactive Neither pressed nor released
Keys Switches that are pressed and released to form chords
Kord® IT Kord® Interface Technology
Kord® Kernel Low level interface between Kord® hardware and software
Kord® OS A runtime library which provides Kord® operational services
MakeChord An action which is initiated when digits are depressed (or after a delay)
Multiplet Requires 2 or more consecutive chord presses to activate
Press To activate a binary input device (eg. switch or key)
Raw chord value A decimalised binary representation of the chord (ambidextrous)
Release To deactivate a binary input device
Singlet A chord action that requires 1 chord press to activate
Singleton A single key chord, ie. only one digit pressed and released
Triplet A chord action that requires 3 consecutive chord presses to activate
