USER INTERFACE FOR ADVANCED INPUT FUNCTIONS
The user interface allowing users to intuitively interact with a virtual keyboard to enter text containing non-alphabetic characters. The user interface uses a special purpose key to input a symbol which can be automatically interpreted as the intended symbol by the device.
1 . A method for correcting text input through an input device comprising:
providing a token database for storing a plurality of tokens, each of the tokens includes a plurality of letters and a special symbol;
receiving a first text input by an input device that includes a special symbol input;
determining by a processor, that the first text sequence includes the special symbol;
comparing by the processor, the first text sequence to the plurality of tokens in the database of tokens;
determining by the processor, that the first text sequence is similar but not identical to one of the plurality of tokens; and
correcting by the processor, the first text sequence with corrected text associated with the one of the plurality of tokens.
2 . The method of claim 1 further comprising:
displaying on a visual display, the corrected text associated with the one of the plurality of tokens.
3 . The method of claim 2 wherein the corrected text associated with the one of the plurality of tokens does not include the special symbol.
4 . The method of claim 1 wherein the plurality of tokens includes URLs.
5 . The method of claim 1 wherein the plurality of tokens includes emails addresses.
6 . The method of claim 1 wherein the plurality of tokens includes passwords.
7 . The method of claim 1 further comprising:
receiving by an input device, a second text sequence;
determining by a processor, that the second text sequence includes the special symbol;
comparing by the processor, the second text sequence to the plurality of tokens in the database of tokens;
determining by the processor, that the second text sequence is not similar to any of the plurality of tokens; and
displaying on the visual display, the second text sequence.
8 . The method of claim 1 further comprising:
receiving a plurality of user defined tokens from the input device; and
storing the plurality of user defined tokens in the token database.
9 . The method of claim 1 further comprising:
storing a plurality of previously known tokens to the token database.
10 . The method of claim 1 wherein the input device is a virtual keyboard that includes letter keys and a special symbol key.
11 . A method for correcting text input through an input device comprising:
providing a token database for storing a plurality of token rules, each of the token rules includes a plurality of letters and a special symbol;
receiving a first text input by an input device that includes a special symbol input;
determining by a processor, that the first text sequence includes the special symbol;
comparing by the processor, the first text sequence to the plurality of token rules in the database of tokens;
determining by the processor, that the first text sequence matches one of the plurality of token rules; and
correcting by the processor, the first text sequence with corrected text associated with the one of the plurality of token rules.
12 . The method of claim 11 further comprising:
displaying on a visual display, the corrected text associated with the one of the plurality of token rules.
13 . The method of claim 12 wherein the corrected text associated with the one of the plurality of token rules does not include the special symbol.
14 . The method of claim 11 wherein the plurality of tokens includes URLs.
15 . The method of claim 11 wherein the plurality of tokens includes emails addresses.
16 . The method of claim 11 wherein the plurality of tokens includes passwords.
17 . The method of claim 11 further comprising:
receiving by an input device, a second text sequence;
determining by a processor, that the second text sequence includes the special symbol;
comparing by the processor, the second text sequence to the plurality of token rules in the database of tokens;
determining by the processor, that the second text sequence is not similar to any of the plurality of token rules; and
displaying on the visual display, the second text sequence.
18 . The method of claim 11 further comprising:
receiving a user defined token rule from the input device; and
storing the user defined token rule in the token database.
19 . The method of claim 11 further comprising:
storing a plurality of previously known token rules to the token database.
20 . The method of claim 11 wherein the input device is a virtual keyboard that includes letter keys and a special symbol key.
