Abstract

In accordance with an example embodiment of the present invention, an apparatus, comprising a processor configured to receive a continuous stroke input related to a virtual keypad, determine input information based at least in part on said continuous stroke input, wherein said input information comprises a first part that excludes a control input and a second part after said first part that comprises a first control input, determine an input operand based at least in part on said first part of said input information and said second part of said input information, and determine an input operation based at least in part on said first part of said input information and said second part of said input information is disclosed.

Claims

1-33. -33. (canceled)

34. An apparatus, comprising a processor configured to:

receive a continuous stroke input related to a virtual keypad;

determine input information based at least in part on said continuous stroke input, wherein said input information comprises a first part that excludes a control input and a second part after said first part that comprises a first control input;

determine an input operand based at least in part on said first part of said input information and said second part of said input information; and

determine an input operation based at least in part on said first part of said input information and said second part of said input information.

35. The apparatus of claim 34, wherein said determination of input information comprises evaluating position information and time information associated with said continuous stroke in relation to position information related to said virtual keypad.

36. The apparatus of claim 34, wherein said processor is further configured to perform said input operation with said input operand.

37. The apparatus of claim 36, wherein said performance comprises sending information associated with said input operation and said input operand to a computer program.

38. The apparatus of claim 34, wherein said first control input relates to character case.

39. The apparatus of claim 38, wherein said second part of said input information comprises at least one character after said first control input.

40. The apparatus of claim 39, wherein determination of said input operand comprises determining case of a character immediately after said first control input based at least in part on said first control input.

41. The apparatus of claim 39, wherein determination of said input operand comprises determining that said second part of input information comprises a second control input relating to character case and determining case of character between said first control input and said second control input based at least in part on said first control input.

42. The apparatus of claim 38, wherein all characters of said input information precede said first control input, and determination of said input operand comprises determining case of said characters of said input information based at least in part on said first control input.

43. The apparatus of claim 38, wherein said input operation relates to text input.

44. The apparatus of claim 34, wherein said first control input relates to deletion.

45. The apparatus of claim 44, wherein said first control input terminates said second part of said input information and said input operation comprises a null operation.

46. The apparatus of claim 44, wherein said second part of said input information comprises at least one character after said first control input, said determination of said input operation excludes said input information before said first control input, and said generation of said input operand excludes said input information before said first control input.

47. The apparatus of claim 34, wherein said first control input relates to a command.

48. The apparatus of claim 47, wherein said input operation relates to input of a command based at least in part on said input information.

49. The apparatus of claim 34, wherein the processor comprises at least one memory that contains executable instructions that if executed by the processor cause the apparatus to:

receive a continuous stroke input related to a virtual keypad;

determine input information based at least in part on said continuous stroke input, wherein said input information comprises a first part that excludes a control input and a second part after said first part that comprises a first control input;

determine an input operand based at least in part on said first part of said input information and said second part of said input information; and

determine an input operation based at least in part on said first part of said input information and said second part of said input information.

50. A method, comprising:

receiving a continuous stroke input related to a virtual keypad;

determining input information based at least in part on said continuous stroke input, wherein said input information comprises a first part that excludes a control input and a second part after said first part that comprises a first control input;

determining an input operand based at least in part on said first part of said input information and said second part of said input information; and

determining an input operation based at least in part on said first part of said input information and said second part of said input information.

51. The method of claim 50, wherein said first control input relates to character case.

52. The method of claim 50, wherein said first control input relates to deletion.

53. A computer-readable medium encoded with instructions that, when executed by a computer, perform:

receiving a continuous stroke input related to a virtual keypad;

determining input information based at least in part on said continuous stroke input, wherein said input information comprises a first part that excludes a control input and a second part after said first part that comprises a first control input;

determining an input operand based at least in part on said first part of said input information and said second part of said input information; and

determining an input operation based at least in part on said first part of said input information and said second part of said input information.
