Problems solved by technology

This method of continuously moving the strokes is prone to several problems: 1. When the user pauses in writing, if the pen is not lifted and the strokes continue to move, ugly drag marks will be generated; 2. When the user lifts the pen to think about the problem, The strokes will keep moving until they disappear, and it is inconvenient for the user to continue to modify the previous strokes; 3. Although the strokes written by the user are automatically moved to the left as the user writes, as if placed on an automatic conveyor belt, the user represents When starting to write a stroke representing one or more characters, in order to distinguish between strokes of different characters, the next stroke must be written on the right side of the previous stroke, as in US Patent US6661509B2 As emphasized in , it is necessary to use a specific vertical line, a space represented by a certain distance, or a specific symbol to distinguish two different words before and after the interval
No matter which method is used, it brings inconvenience to the user's writing process

Embodiment 1

[0036] see Figure 4 , the invention discloses a method for automatically scrolling electronic ink during handwriting input, said method comprising the following steps:

[0037] [Step 110] Input strokes on the touch screen through a handwriting input unit; the handwriting input unit can be a stylus, a finger, and the like.

[0038] [Step 120] The handwriting input unit moves on the touch screen, records and displays the movement trajectory in the handwriting area on the touch screen, that is, electronic ink; at the same time, the movement trajectory of the handwriting input unit automatically moves to the first direction so as to provide the user with continuous writing Space; such as moving to the left automatically to provide space for the user to write to the right. The trajectory of the stylus automatically moves to the left as if placed on an automatic conveyor belt to provide space for the user to write to the right. The speed of moving to the left can be at a constant...

Embodiment 2

[0055] In the first embodiment, the movement track of the handwriting input unit automatically moves to the left to provide space for the user to write to the right. In this embodiment, the movement track of the handwriting input unit automatically moves to the right so as to provide space for the user to write to the left. Alternatively, the movement track of the handwriting input unit automatically moves upwards to provide space for the user to write. Alternatively, the movement track of the handwriting input unit automatically moves downwards to provide space for the user to write.

Embodiment 3

[0057] The method of the present invention may further include: a handwriting moving direction selection step, selecting the moving direction of the input handwriting through a handwriting moving direction selection module, which is convenient for the user to select.

Abstract

The invention discloses a method for automatically rolling electronic ink during handwriting input. When a user continuously writes with a handwriting pen or finger on a touch screen, the written electronic ink automatically moves leftwards along with the writing of the user like the electronic ink is placed on an automatic conveying belt, thereby providing space for continuously writing for the user in a limited writing area. Compared with a traditional rolling method, the method of the invention can provide the user with better writing experience and a more natural writing mode.

Description

technical field [0001] The invention belongs to the technical field of handwriting input, and relates to an input method, in particular to a method for automatically scrolling electronic ink during handwriting input. Background technique [0002] In recent years, handwritten text input has been widely used as an important text input method on mobile devices such as mobile phones with touch screens. In daily life, people are often used to continuously write a line of text from left to right, but on mobile devices, due to the limitation of the size of the touch screen, when performing handwriting input, people need to be in a designated area (one in the touch screen) The area limited by the rectangular frame or the entire touch screen) repeatedly overlaps and writes the text that is originally connected from left to right. In this way, different characters are generally distinguished by a certain delay, or the user pauses for a certain period of time after writing a character...
