Abstract

On a device having keys with multiple values, a user may perform either an iterative directory filtering operation or a direct-dial operation, without specifying which of the operations is intended. Hence, a user is allowed to perform any of a number of different operations to specify a number to be dialed or to identify a directory record, without requiring the user to specify a mode. A user'"'"'s intended operation is determined by analyzing the entered keystrokes, and activates the appropriate feedback and functionality for the determined operation. In one embodiment iterative directory filtering is performed on multiple fields concurrently, including derived fields and combination fields.

Claims

1. A computer-implemented method for concurrently accepting parameters in at least two contexts, the method comprising:

receiving, in a mobile computing device, a character sequence comprising at least one character, each character having a first value associated with a first operating mode, and at least one of the characters having a second value associated with a second operating mode;

in response to receiving the character sequence, automatically determining whether the character sequence produces a valid result in a first context associated with the first operating mode;

in response to determining the character sequence produces a valid result in the first context, performing a first action in the first operating mode using the first value for each character;

in response to determining the character sequence does not produce a valid result in the first context, automatically determining whether at least one of the characters in the character sequence produces a valid result in a second context associated with the second operating mode; and

in response to determining the character sequence does not produce a valid result in the first context and determining at least one of the characters in the character sequence produces a valid result in the second context, performing a second action in the second operating mode using the second value for at least one of the characters.

2. The method of claim 1, wherein automatically determining whether the character sequence produces a valid result in the first context associated with the first operating mode comprises searching a directory to determine whether the character sequence matches one or more records in the directory.

3. The method of claim 2, further comprising:

in response to determining the character sequence produces a valid result in the first context, enabling a user to select a record in the directory that matches the character sequence.

4. The method of claim 1, further comprising:

receiving an input identifying the first operating mode or the second operating mode.

5. The method of claim 1, wherein determining whether the character sequence produces the valid result in the first context associated with the first operating mode comprises:

determining whether one or more characters in the character sequence have an alphabetic value.

6. The method of claim 1, wherein determining whether at least one of the characters in the character sequence produces the valid result in a second context comprises:

determining whether a character in the character sequence has a numeric value.

7. The method of claim 1, wherein performing the first action in the first operating mode comprises:

displaying, on a display device, a first feedback indicating character input according to the first value of each character in the character sequence.

8. The method of claim 1, wherein performing the second action in the second operating mode comprises:

displaying, on a display device, a second feedback indicating character input according to the second value of at least one character in the character sequence.

9. The method of claim 1, wherein receiving the character sequence comprising at least one character comprises:

receiving a keystroke sequence from a plurality of keys, one or more of the keys having the first value associated with the first operating mode and the second value associated with the second operating mode.

10. The method of claim 9, wherein the plurality of keys comprise a keyboard.

11. The method of claim 9, wherein the plurality of keys comprise a dial pad.

12. A non-transitory computer-readable medium storing instructions for concurrently accepting parameters in at least two contexts, the instructions, when executed by a processor, causes the processor to perform steps comprising:

receiving a character sequence comprising at least one character, each character having a first value associated with a first operating mode, and at least one of the characters having a second value associated with a second operating mode

in response to receiving the character sequence, automatically determining whether the character sequence produces a valid result in a first context associated with the first operating mode;

in response to determining the character sequence produces a valid result in the first context, performing a first action in the first operating mode using the first value for each character;

in response to determining the character sequence does not produce a valid result in the first context, automatically determining whether at least one of the characters in the character sequence produces a valid result in a second context associated with the second operating mode; and

in response to determining the character sequence does not produce a valid result in the first context and determining at least one of the characters in the character sequence produces a valid result in the second context, performing a second action in the second operating mode using the second value for at least one of the characters.

13. The non-transitory computer-readable medium of claim 12, wherein the instructions cause the processor to automatically determine whether the character sequence produces a valid result in the first context associated with the first operating mode by searching a directory to determine whether the character sequence matches one or more records in the directory.

14. The non-transitory computer-readable medium of claim 12, wherein the instructions further cause the processor to:

receive an input identifying the first operating mode or the second operating mode.

15. The non-transitory computer-readable medium of claim 12, wherein the instructions further cause the processor to:

in response to determining the character sequence produces a valid result in the first context, enable a user to select a record in the directory that matches the character sequence.

16. The non-transitory computer-readable medium of claim 12, wherein the instructions cause the processor to determine whether the character sequence produces the valid result in the first context associated with the first operating mode by determining whether one or more characters in the character sequence have an alphabetic value.

17. The non-transitory computer-readable medium of claim 12, wherein the instructions cause the processor to determine whether at least one of the characters in the character sequence produces the valid result in a second context by determining whether a character in the character sequence has a numeric value.

18. A system for concurrently accepting parameters in at least two contexts, the system comprising:

an input device to receive a character sequence, the character sequence comprising at least one character, each character having a first value associated with a first operating mode, and at least one of the characters having a second value associated with a second operating mode;

a buffer, coupled to the input device, to store the character sequence received by the input device;
