`
`(New) A method comprising:
`
`detecting a touch input from both outside and inside of a constrained writing region of a
`
`touch-sensitive space of a device; and
`
`generating an input character based on a character recognition of the touch input from
`
`both outside and inside of the constrained writing region.

`(New) The method of claim 22, wherein generating the input character
`
`comprises:
`
`determining that the touch input follows within a threshold amount of time a previous
`
`touch input that was used to generate another input character, and
`
`based on the determination, providing the detected touch input from both outside and

`inside of the constrained writing region to a character recognizing engine to translate the touch
`
`input from both outside and inside of the constrained writing region to the input character.

`(New) The method of claim 26, further comprising:
`
`for each respective edge in the graph, associating a score for each candidate character,
`
`and
`
`wherein identifying the plurality of characters comprises selecting the path through the
`
`edges of the graph that produces a best score based on the score of a selected character for each
`
`respective edge on the path.
`
`28.
`
`(New) The method of claim 26, wherein the plurality of edges comprises a
`
`single-stroke edge between a pair of adjacent nodes in the graph for representing one or more
`
`single stroke characters, and a multi-stroke edge between a pair of non-adjacent nodes in graph
`
`representing one or more multi-stroke characters.

`
`29.
`
`(New) The method of claim 26, wherein defining the set of candidate characters
`
`for each edge comprises using spatial, temporal, and language constraints to limit the candidate
`
`characters to include in the set.
`
`30.
`
`(New) The method of claim 26, wherein each of the plurality of nodes
`
`corresponds to a touch-up of a prior stroke and a touch-down of a subsequent stroke.
`
`3 1.
`
`(New) The method of claim 21, further comprising:
`
`identifying a series of characters input on the touch-sensitive space of the device,
`
`determining that the identified series of characters includes an improper combination of
`
`at least one upper case character and one lower case character, and
`
`responsive to the determining, presenting the series of characters with at least one of the
`
`inputted characters having a modified character case.

`
`nodes, each node corresponding to a touch-down event or a touch-up event of at least one
`
`of the plurality of touch-input strokes, each edge between a pair of nodes representing
`
`one or more characters,
