Apparatus and method for handwriting recognition
First Claim
1. An apparatus comprising:
- a touch-sensitive display screen providing a handwriting input area capable of detecting hand-made user input; and
a processing device providing a user interface to a user via the touch-sensitive display screen, wherein;
the handwriting input area includes a writing start area capable of switching between a first two-dimensional size and a second two-dimensional size, larger than the first two-dimensional size, wherein said writing start area is smaller than said handwriting input area; and
in thatthe processing device is configured to handle said hand-made user input as either a logical mouse event, associated with a control operation for said user interface, or a logical pen event, associated with handwriting;
wherein user input within the writing start area when having its first two-dimensional size is handled as a logical mouse event and causes the writing start area to switch to its second two-dimensional size;
wherein user input that starts within the writing start area when having its second two-dimensional size and ends anywhere within the handwriting input area including outside said writing start area is handled as a logical pen event and causes interpretation of the user input as a symbol from a plurality of predefined symbols, said plurality of predefined symbols including a first symbol set and a second symbol set, and said writing start area comprising a first subarea and a second subarea, each being capable of switching between a first two-dimensional size and a second two-dimensional size, larger than the first two-dimensional size;
wherein user input within either of said first subarea and second subarea, when having its respective first two-dimensional size, is handled as a logical mouse event and causes a switch to its second two-dimensional size;
wherein user input that starts within said first subarea, when having its second two-dimensional size, is handled as a logical pen event and causes interpretation of the user input as a symbol from said first symbol set;
wherein user input that starts within said second subarea, when having its second two-dimensional size, is handled as a logical pen event and causes interpretation of the user input as a symbol from said second symbol set; and
wherein the symbol from said first symbol set and the symbol from said second symbol set are combinable into a sequence of symbols.

Abstract
An apparatus (100) for handwriting recognition has a touch-sensitive display screen (240) providing a hand writing input area (270) capable of detecting hand-made user input. The apparatus also has a processing device (300) coupled to the touch-sensitive display screen and providing a user interface to a user. The handwriting input area (270) includes a writing start area (280) capable of switching between a first two-dimensional scope (282) and a second two-dimensional scope (282′), larger than the first two-dimensional scope. The processing device (300) is configured to handle said handmade user input as either a logical mouse event, associated with a control operation for said user interface, or a logical pen event, associated with handwriting. User input within the writing start area when having its first two-dimensional scope is handled as a logical mouse event and causes the writing start area to switch to its second two-dimensional scope, Furthermore, user input that starts within the writing start area when having its second two-dimensional scope is handled as a logical pen event and causes interpretation of the user input (252) as a symbol (254) from a plurality of predefined symbols.

15. A method comprising:
-
providing, within a handwriting input area, a writing start area capable of switching between a first two-dimensional size and a second two-dimensional size, larger than the first two-dimensional size; wherein said writing start area is smaller than said handwriting input area; detecting user input within the writing start area; handling user input, when said writing start area has its first two-dimensional size, as a logical mouse event and in response switching the writing start area to its second two-dimensional size; handling said user input, when said writing start area has its second two-dimensional size and said user input starts within the writing start area and ends anywhere within the handwriting input area including outside said writing start area, as a logical pen event and in response interpreting said user input as a symbol from a plurality of predefined symbols, said plurality of predefined symbols including a first symbol set and a second symbol set, and said writing start area comprising a first subarea and a second subarea, each being capable of switching between a first two-dimensional size and a second two-dimensional size, larger than the first two-dimensional size; wherein user input within either of said first subarea and second subarea, when having its respective first two-dimensional size, is handled as a logical mouse event and causes a switch to its second two-dimensional size; wherein user input that starts within said first subarea, when having its second two-dimensional size, is handled as a logical pen event and causes interpretation of the user input as a symbol from said first symbol set; wherein user input that starts within said second subarea, when having its second two-dimensional size, is handled as a logical pen event and causes interpretation of the user input as a symbol from said second symbol set; and wherein the symbol from said first symbol set and the symbol from said second symbol set are combinable into a sequence of symbols. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
