Description

Intelligent whiteboard input method and intelligent whiteboard Technical Field The application relates to the technical field of intelligent whiteboard interaction, in particular to an intelligent whiteboard input method and an intelligent whiteboard. Background The intelligent interactive whiteboard is electronic equipment integrating a touch display screen, a computing unit and a special operating system, and aims to realize efficient interaction between a user and display content. Along with the development of science and technology, the application scene is increasingly wide, and the demands of users on the text input efficiency are also continuously improved. At present, the mainstream intelligent interactive whiteboard is generally provided with an android operating system, the input mode of the intelligent interactive whiteboard mainly depends on a virtual keyboard, and a user needs to select input contents word by word in candidate bars, so that the overall input efficiency is low. In the prior art, part of intelligent interactive whiteboards support a handwriting input function by being provided with a handwriting pen and by means of a third-party input method, so that a user is allowed to write or draw in a preset specific area through the handwriting pen, handwriting track data are collected by the third-party input method, and the handwriting track data are converted into standard texts to finish input.
