Dynamic key assignment in key pad

A method for dynamic key assignment on an intelligent device having a display screen and a keypad with at least a first key most ergonomically reachable by a user, the method comprising:

• identifying a list of characters upon an entry of an initial input character;
• determining a likelihood of each of the characters to follow the initial input character based on frequency of use with the initial input character;
• reassigning one of the characters that is most likely to follow the initial input character to the first key in the keypad, wherein the first key, when activated, causes an entry of the one of the characters that is most likely to follow the initial input character, and
• wherein, if the one of the characters that is most likely to follow the initial input character is not selected by the user to follow the initial input character, a second key assigned with a next one from the characters is activated to enter the next one character.

A method for dynamic key assignment on a standard telephone keypad, and a user interface including a data entry field, the method comprising:

• determining a convenient key that is the one of the nine keys most ergonomically reachable by a user;
• identifying a predefined list including a plurality of valid input words;
• parsing the valid input words in the predefined list to extract a set of valid characters respectively associated with a first letter of each of the valid input items;
• determining a frequency of use associated with each of the valid characters;
• displaying each of the valid characters according to the corresponding frequency of the each of the valid characters, such that the valid characters are presented on the display in a standard telephone keypad arrangement, wherein characters with higher frequencies are selectable with fewer keystrokes different from the convenient key than characters with lower frequencies;
• accepting a selected character;
• and
• displaying the selected character in the data entry field.
