In this embodiment, when the touch and talk function of the touch and talk pen is realized, the touch and talk pen needs to be divided into two parts, namely projection and identification; the projection part is realized through laser projection equipment, and the identification part is realized through a reading pen.
Specifically, in an implementation manner of this embodiment, before projection is performed by the laser projection device, a content to be read needs to be input in the terminal; the content to be read can be input into a database of the terminal through media such as a U disk, a memory card and the like, and can also be stored into the database of the terminal in a downloading and storing mode; when the point reading operation is needed, the terminal acquires the content to be read from the database so as to process the content to be read, so that the content can be projected by the laser projection equipment.
When the content to be read is processed, the terminal firstly determines the file type of the content to be read, then acquires a corresponding preset conversion format according to the file type of the content to be read, converts the content to be read into a picture through the preset conversion format, and projects the picture on a projection surface through laser projection equipment; the preset conversion format can be a format of converting a document into a picture, and can also be a format of converting a two-dimensional code into a picture.

step S110, acquiring input content to be read;
and step S120, converting the content to be read into a picture according to a preset conversion format.
In this embodiment, the converted picture includes text information and/or two-dimensional code information, and if the content to be read is text information, the converted picture includes the text information; if the content to be read is two-dimension code information, the converted picture comprises the two-dimension code information; therefore, when the content to be read is converted into the picture, corresponding processing can be carried out according to the file type of the content to be read.

That is, in an implementation manner of this embodiment, the step S300 specifically includes the following steps:
step S310, acquiring a picture in the projection plane through a built-in camera of the reading device;
step S320, extracting the character information in the picture to obtain the content to be read;
alternatively, the first and second electrodes may be,
step S330, identifying the two-dimension code information in the picture, and converting the two-dimension code information into corresponding text information to obtain the content to be read.
In this embodiment, when the content to be read needs to be updated, the content to be read can be directly changed through the terminal or other terminals; after the content is changed, the changed content is converted into a corresponding picture, then the picture is sent to the laser projection equipment, and the changed display content is projected through the laser projection equipment so as to improve the ductility of the content to be read; meanwhile, when the laser projection equipment projects the updated content to be read, the terminal sends corresponding prompt information to the reading pen so as to prompt the user to read the updated content in time through the reading pen.
Therefore, in the embodiment, the content to be read is obtained and sent to the projection device, and the content to be read required by the reading device is displayed in a projection mode, so that the function of projecting the content to be read by laser is realized, the traditional paper mode of displaying the content to be read is replaced, the consumption of paper materials is reduced, and meanwhile, the ductility of the content to be read required by the reading device is improved.
