The invention discloses an interactive teaching
system and method of a touch type mobile terminal. Touch track or
handwriting dot matrix data generated from a teacher terminal and student terminals are transmitted to a classroom computer through socket communication, the track or
handwriting dot matrix data are recovered through the teacher computer and redrawn to
handwriting images to be presented on a screen of the teacher computer, accordingly, students can see blackboard-writing made by the teacher on a
projector, problem answering writing content of the students can be taken on the
projector in class, the storage quantity of handwriting
dot matrix data is small, the handwriting dot matrix data are convenient to transmit, a classroom memoir mode, a PPT playing and blackboard-writing interactive teaching mode, a teacher-student interactive teaching mode, a student-student interactive teaching mode and a group discussion teaching mode are also provided, frequent
data exchange among the student terminals is avoided, data loads needing to be transmitted through a
wireless local area network are minimized, and the
system and method are novel in concept and ingenious in implementation and have good application prospects.
