Embodiment 1
[0053] figure 1 A structural diagram of a teacher-side question-answering device provided in Embodiment 1 of the present invention. This embodiment is applicable to online teaching. The teacher-side question-answering device 1 provided in this embodiment includes: a question-and-answer book 11, a digital pen 12, and a teacher's client13.
[0054] Wherein, the dot matrix array is configured in the answer book 11; the digital pen 12 is used to collect the dot matrix position association information associated with the position written by the teacher in the answer book 11, and the dot matrix position association information is sent to the teacher client 13; The teacher client 13 is configured to construct a handwritten answering data packet according to the received dot matrix position association information, and send the handwritten answering data packet to the student client through the UDP reliable transmission mechanism.
[0055]Preferably, the answer book 11 includes at le...
Embodiment 2
[0061] This embodiment is optimized based on the above embodiments, and specifically, the working process of the teacher client in the above embodiments is further elaborated in detail. The teacher client is specifically used to: send a set number of handwritten answering data packets to be confirmed to the student client, and store the handwritten answering data packets to be confirmed in the sending window; receive the voice answering packet sent by the student client , wherein, the voice response packet is accompanied by handwritten answering data packet confirmation information; according to the handwritten answering data packet confirmation information, slide the sending window, and delete the confirmed handwritten answering data packet from the sending window , generating an idle sending window; continue to send the handwritten answering data packet to be confirmed matching the quantity of the idle sending window to the student client, and store the handwritten answering ...
Embodiment 3
[0078] This embodiment is optimized on the basis of the above-mentioned embodiments, and specifically, the working process of the digital pen in the above-mentioned embodiments is further elaborated in detail. The digital pen is specifically used for: according to the set sampling frequency, periodically collect the dot matrix position related information written by the teacher in the answer book, and send the dot matrix position related information to the teacher client through the universal serial bus .
[0079] Specifically, the set sampling frequency can be determined according to the actual acquisition effect of the digital pen, preferably, the set sampling frequency is times / ms, that is, the sampling period is 18ms / time. By printing an invisible dot matrix pattern on the answer book, the high-speed camera at the front of the digital pen captures the movement trajectory of the pen tip at any time, and finally sends the dot matrix position related information to the teac...
