FIG. 2 is a flowchart illustrating an interactive wireless teaching method according to a second embodiment of the present invention; as shown in fig. 2, the method in this embodiment may include the following steps:
s201, the dot matrix data reading device obtains dot matrix feedback data generated when the student operates on the medium by using the dot matrix reading device, and sends the dot matrix feedback data to a background server through a wireless communication channel.
