Abstract

Disclosed is the front of a screen interface for a computer system with pen and tablet devices for handwritten data input. A system has a built-in handwriting recognizer that can convert a series of handwritten stroke inputs into character strings. By using the proposed interface, a user can enter text data easily into a document on a screen at any position, in any direction and in any size without causing any degradation of the recognition accuracy.

This text was extracted from an ASCII text file.
This is the abbreviated version, containing approximately 54% of the total text.

User Interface for Data Entry with a Pen Device

      Disclosed is the front of a screen interface for a computer
system with pen and tablet devices for handwritten data input.  A
system has a built-in handwriting recognizer that can convert a
series of handwritten stroke inputs into character strings.  By using
the proposed interface, a user can enter text data easily into a
document on a screen at any position, in any direction and in any
size without causing any degradation of the recognition accuracy.

      One of the most important features of this invention is a
method for generating a character entry grid at a required position
and in a required direction.  As shown in Fig. 1, the system
generates a grid with several character entry spaces in a direction
and at a position specified by a gesture 'arrow.'  Then, the user can
enter a handwritten character into each space.  If the user reaches
the end of the grid and wants to enter more characters, the system
automatically extends the grid into the adjacent area.  If the user
enters a 'carriage return' character, the system generates a grid on
the line after the existing grid.

      Thus, a user can enter text lines at desired positions and in
desired directions on a screen by means of gestures.  The interface
is effective and easy to use for entering a text into a written
document displayed on a screen.

      Another important feature of this invention is a method for
displaying control buttons...
