Method of selecting characters from a keypad and a telephone set operating according to this method
First Claim
1. A method of selecting characters from a group of characters assigned to a single key, in particular a key of a telephone dialing keypad each key of which having a number of alphanumeric and other characters assigned to it;
- the actuation of a key invokes a cursor controlled display of the characters assigned to said key;
the cursor is held at its position while a particular key is actuated within a predetermined time interval; and
the cursor is automatically moved to an other position if said key is not further actuated within said time interval such to form a character string comprising at least one character, wherein the selection of a character is controlled in connection with accessing character data entries stored in memory means, a data entry stored in said memory means is retrieved and displayed which matches closest to a selected character string, and said cursor is held at its position if the corresponding character of the retrieved data entry and the selected character at the cursor position do not match.

Abstract
There is disclosed a method of selecting characters from a group of characters assigned to a single key, in particular a key of a telephone dialling keypad. Actuation of a key (8; 16) invokes a cursor controlled display of the characters (2; 18). The cursor is held at a particular position (11) while a key is actuated within a predetermined time interval (t1 ; 6, 7). The character string corresponding to a particular key actuation is read (18) and is used for the retrieval of the closest matching data entry from memory means (19). If the key is not further actuated within this time interval (t1), the cursor is moved to a next position (22), provided the selected character string matches any of the data entries of the memory means (20, 21). The retrieved data entry may be used, inter alia, for automatic dialling purposes. The method is applied in a telephone set having memory means containing subscriber data.

- the actuation of a key invokes a cursor controlled display of the characters assigned to said key;
- 6. A telephone set, in particular a radio telephone set, including processor control means, visual display means and telephone dialing keypad means, each key of said keypad means having a number of alphanumeric and other characters assigned to it, wherein said processor control means, keypad means and display means are operatively connected such that actuation of a key invokes a cursor controlled display of the characters assigned to said key, said telephone set comprises timer means for setting a predetermined time interval, such that under the control of said processor control means the cursor is held at a particular display position while a key of said keypad means is actuated during said time interval and wherein the cursor is moved to an other position if said key is not further actuated within said time interval, as a result of which a character string comprising at least one character is formed, wherein said telephone set comprises memory means operatively connected to said processor control means for retrieving character data entries stored in said memory means, and wherein the processor control means are arranged to hold the cursor at its position in case the selected character string does not match any of the data entries.

16. A method for entering an input string of at least one alphanumeric character into a device, said device including a keypad with at least one key, each key corresponding to a set of at least one alphanumeric character, comprising the steps of:
-
displaying, upon actuation of one of said keys, a cursor and a next specific character corresponding to said one actuated key at a current cursor position of a display of said device; selecting a most likely candidate string from a set of at least one candidate string stored in a memory of said device, wherein said most likely candidate string represents a closest match to said next specific character as compared to other candidate strings in said stored set of at least one candidate string; displaying said most likely candidate string on said display of said device; determining whether a particular character of said most likely candidate string is an exact match of said next specific character; holding said current cursor position and awaiting an additional key actuation when said particular character of said most likely candidate string is not an exact match of said next specific character; initiating a timer when said particular character of said most likely candidate string is an exact match of said next specific character; accepting said next specific character as a potential character in said input string, advancing said current cursor position, and awaiting an additional key actuation when said one actuated key is not again actuated before said timer expires; and holding said current cursor position and returning to said step of displaying a cursor and a next specific character corresponding to said one actuated key when said one actuated key is again actuated before said timer expires. - View Dependent Claims (17, 18)
