Abstract

The present application relates to an accelerated writing method, apparatus, electronic device and computer-readable storage medium, which comprises: sending a first color to a second system under a condition that a first system starts a first writing operation according to a writing input information received with a first color, and simultaneously following the writing input information to display a first writing trajectory; directly sending a display request to the first system by the second system; rendering a first preset trajectory with the first color at the first preset position, and sending an completing command to the second system; obtaining, by the second system, a rendering color of the first preset writing trajectory at the first preset position as a second color; starting, by the second system, the second writing operation with the second color, and following the writing input information received to display a second writing trajectory.

Dependent claims

An accelerated writing method, comprising:

a first writing step:
sending, by a first system, a first color to a second system under a condition that the first system starts a first writing operation according to a writing input information received with a first color, and simultaneously following the writing input information to display a first writing trajectory formed by the first writing operation;
a request sending step:
sending, by the second system, a display request to the first system in response to receiving the first color, wherein the display request comprises displaying the first color at a first preset position of a display screen;
a rendering step:
rendering, by the first system, a first preset trajectory with the first color for a first preset time at the first preset position in response to receiving the display request, and sending a completing command to the second system;
an obtaining step:
in response to receiving the completing command, obtaining, by the second system, a rendering color of the first preset writing trajectory at the first preset position after waiting a second preset time as a second color;
a second writing step:
starting, by the second system, a second writing operation with the second color, and following the writing input information received to display a second writing trajectory formed by the second writing operation,
wherein the second writing trajectory is displayed faster on the display screen than the first writing trajectory.

8 more elements

An accelerated writing apparatus, comprising a first system and a second system, wherein the first system comprises:

a first writing unit configured to send a first color to the second system under a condition that the first system starts a first writing operation according to a writing input information received with the first color, and simultaneously follow the writing input information to display the first writing trajectory formed by the first writing operation;
a rendering unit configured to render a first preset trajectory with the first color for a first preset time at the first preset position in response to receiving the display request, and send a completing command to the second system;
and
the second system comprises:
a request sending unit configured to send a display request to the first system in response to receiving the first color, wherein the display request comprises displaying the first color at the first preset position of the display screen;
an obtaining unit configured to, in response to receiving the completing command, obtain a rendering color of the first preset writing trajectory at the first preset position after waiting a second preset time as the second color;
the second writing unit configured to start a second writing operation with the second color, and follow the writing input information received to display the second writing trajectory formed by the second writing operation;
wherein the second writing trajectory is displayed faster on the display screen than the first writing trajectory.

5 more elements

An electronic device, comprising an interactive large screen or an electronic whiteboard, wherein the electronic device comprises a first system and a second system,

the first system comprising:
a first writing unit configured to send a first color to the second system under a condition that the first system starts a first writing operation according to a writing input information received with the first color, and simultaneously follow the writing input information to display the first writing trajectory formed by the first writing operation;
a rendering unit configured to render a first preset trajectory with the first color for a first preset time at the first preset position in response to receiving the display request, and send a completing command to the second system;
and
the second system comprising:
a request sending unit configured to send a display request to the first system in response to receiving the first color, wherein the display request comprises displaying the first color at the first preset position of the display screen;
an obtaining unit configured to in response to receiving the completing command, obtain a rendering color of the first preset writing trajectory at the first preset position after waiting a second preset time as the second color;
the second writing unit configured to start a second writing operation with the second color, and follow the writing input information received to display the second writing trajectory formed by the second writing operation;
wherein the second writing trajectory is displayed faster on the display screen than the first writing trajectory.
