Claim 7

The computer program product of claim 4, wherein said recognition manager program means is connected to said stroke router, and includes means for causing said computer to store said received strokes, for causing said computer to pass said received strokes to said handwriting recognizer program means for recognition, and for causing said computer to relay said recognized strokes from said handwriting recognizer program means back to said application program means.

Claim 8

The computer program product of claim 5, wherein said mediator program means includes means for causing said computer to implement a protocol between said application program means and said error correction module program means, said protocol having means for causing said computer to facilitate retrieval of said recognized strokes by said error correction module program means from said application program means.
