Inputting tone and diacritic marks by gesture

A method comprising:

• displaying a keypad for text input, the keypad including a plurality of keys,
• receiving input indicating a selection of a key from the plurality of keys, the key representing a consonant,
• receiving a gesture input, wherein the gesture input is associated with one gesture of a set of gestures, each gesture in the set being semantically linked to a tone, and wherein the set of gestures comprises:
• a substantially horizontal movement associated with a first tone,
• a movement both horizontal and vertical in a first direction associated with a second tone,
• a movement both horizontal and vertical in a second direction, then a movement both horizontal and vertical in a third direction associated with a third tone, and
• a movement both horizontal and vertical in a fourth direction associated with a fourth tone, and
• displaying a grapheme based upon the selected key and the tone associated with the received gesture,
• wherein the grapheme is a modified version of a word associated with the selected key and the grapheme is predicted based on only the consonant and the tone associated with the received gesture.

A system comprising:

• a processor configured to:
• display a keypad for text input to a user, the keypad including a plurality of keys,
• receive input from the user indicating a selection of a key from the plurality of keys, the key representing a consonant,
• receive a gesture input from the user, wherein the gesture input is associated with one gesture out of a set of gestures, each gesture in the set being semantically linked as defined by the user to at least one property selected from:
• a phonological property and a diacritic property, and
• display a grapheme based upon the selected key and at least one of the phonological property and the diacritic property semantically linked to the received gesture,
• wherein the grapheme is a modified version of a word associated with the selected key and the grapheme is predicted based on only the consonant and the at least one property associated with the received gesture.
