The writing page placed on the designated area 40 may be a book, an exercise book, a drawing book, a test paper, or the like, which is not particularly limited in the embodiment of the present invention.

In the embodiment of the invention, the writing content written by the user on the writing page can be Chinese or English, and the embodiment of the invention is not limited. If the writing content is Chinese, the writing content unit is a Chinese character; if the written content is English, the written content unit is an English word. For ease of understanding, embodiments of the present invention will be described using the written content as chinese and the written content unit as a chinese kanji, for example, assuming that the written content is "bright moon light before bed", then "bed", "front", "bright", "moon" and "light" are written content units. In the embodiment of the invention, the electronic equipment can acquire the size of the written content unit written by the user on the written page.

As an alternative embodiment, the writing page may be provided with a plurality of field grids, where the field grids may provide location guidance for the writing of the writing content units by the user, and step 101 the electronic device obtains the size of the writing content units written by the user on the writing page, including:

102. The electronic device compares the size of the writing content unit with a preset standard size to obtain a deviation value between the size of the writing content unit and the preset standard size, and the deviation value is used as a deviation value corresponding to the writing content unit.

In the embodiment of the present invention, the size may be the number of fonts, the number of pounds or the number of millimeters, which is not limited.

In the embodiment of the invention, the preset standard size can be an identification size which is set by a developer through a large number of experimental results and meets the identification requirement of the electronic equipment, and the embodiment of the invention is not limited.

For convenience of understanding, in the embodiment of the present invention, the number of pounds of the font is taken as an example, and in the embodiment of the present invention, for example, assuming that a size of a certain writing content unit is 12 and a preset standard size is 16, the electronic device compares the size of the writing content unit with the preset standard size to obtain a deviation value between the size of the writing content unit and the preset standard size is 4.

The user interaction instruction includes, but is not limited to, an instruction input by a user in any interaction mode of voice interaction, remote controller interaction, gesture interaction, image interaction, voiceprint interaction, somatosensory interaction and the like. For example, the user presets the dictation ending instruction for starting the dictation ending program as an image interaction instruction through the electronic device, so that the electronic device can shoot an image or a video stream of the dictation process of the user through a shooting module arranged on the electronic device, automatically detect whether the user puts down a pen for writing in the image or the video stream, and judge that the dictation ending instruction input by the user is received when detecting that the user puts down the pen for writing in the image.

In the embodiment of the invention, the electronic equipment can detect the writing content (comprising a plurality of writing content units) according to the standard answer, and compared with the standard answer, the writing content units which are different from the standard answer in the writing content are error content units in the writing content. For example, the standard answer is "bright moon before bed, suspected of frosting. The head is looked at bright moon, the head is thought of as hometown, the writing content is' bright moon before bed, and the frost is suspected to be on the ground. The head is raised to be bright moon, and the head is lowered to be the hometown, and the error content unit is raised.
