Abstract

According to one embodiment, an information processing system includes a recorder and a first detector. The recorder is configured to record stroke data representing strokes written by hand. An order relationship between the stroke data items is recognizable in the stroke data. The first detector is configured to detect an orientation of a character corresponding to the strokes represented by the stroke data, based on a positional relationship and an order relationship between at least two strokes.

Claims

1. An information processing system comprising:

a recorder configured to record stroke data representing strokes written by hand, an order relationship between the stroke data being recognizable in the stroke data; and

a first detector configured to detect an orientation of a character corresponding to the strokes represented by the stroke data, based on a positional relationship and an order relationship between at least two strokes.

2. The system of claim 1, further comprising a recognition module configured to recognize the character corresponding to the strokes represented by the stroke data,

wherein the recognition module is configured to adjust an orientation of a character block region including at least two characters as one character string, based on the orientation of the character detected by the first detector.

3. The system of claim 2, further comprising an adjusted document display module configured to display characters corresponding to character codes acquired by the recognition module, based on position data of a character block region extracted by the recognition module.

4. The system of claim 1, wherein the first detector is configured to detect the orientation of the character corresponding to the strokes represented by the stroke data, by comparing the direction of motion from first stroke data to second stroke data following the first stroke data with two directions prescribed as horizontal and vertical direction for moving a writing instrument, respectively.

5. The system of claim 1, further comprising a second detector configured to detect an orientation of a touchscreen display based on the orientation of the character detected by the first detector.

6. The system of claim 1, further comprising a handwritten-document display module configured to display loci represented by the stroke data to a touchscreen display.

7. A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to function as:

a recording module configured to record stroke data representing strokes written by hand, an order relationship between the stroke data being recognizable in the stroke data; and

a first detector configured to detect an orientation of a character corresponding to the strokes represented by the stroke data, based on a positional relationship and an order relationship between at least two strokes.

8. An information processing method in an information processing system, the method comprising:

recording stroke data representing strokes written by hand, an order relationship between the stroke data being recognizable in the stroke data; and

detecting an orientation of a character corresponding to the strokes represented by the stroke data, based on a positional relationship and an order relationship between at least two strokes.
