Abstract
The invention relates to a novel electromagnetic intelligent whiteboard. The whiteboard can be used as a projection screen or writing board for man-machine interaction. The invention has the main characteristics that two pen with different frequencies can be used at the same time for writing on the projection surface of the whiteboard; and the display function of the blackboard-writing can be realized by time sharing processing and precise positioning of software to display letters, so that the interaction performance of the whiteboard is stronger.
Description
Technical field:
The present invention is a tool intelligent whiteboard of double-pen writing simultaneously, is applied in the relevant field such as interactive teaching.
Summary of the invention:
The present invention provides a blank with double-pen writing function of different frequency, the built-in mesh lines of blank main body is connected with projection, blank by computing machine, and software systems receive the feedback signal in the different coils, judge the position of pen, the time-division processing function of software shows content written.
Background technology:
Common electronic whiteboard now has been applied in the field such as teaching, training, mainly is that single people participates in operation.Our this pair pen is writing function intelligent whiteboard simultaneously, the time-division processing software systems of being furnished with special-purpose special use, detect the position of the pen of different frequency constantly, and feedback signal passed to computing machine, pen that can two personal different frequencies is write operation in projection surface.
Background of the present invention can realize by following measure:
According to method of the present invention, the intelligent whiteboard of dual-stylus writing function is furnished with the time writer of different frequency, judged the position of pen by the coil receiving feedback signals by software, utilize special-purpose software systems time-division processing function, in time be presented at the written contents of zones of different, realize the interactive operation of two people on same blank, can show timely interaction content and result on the blank, make two people participate in simultaneously human-computer interaction in, reach the effect of teaching through lively activities.
The present invention has following advantage than prior art:
The present invention is the intelligent whiteboard of double-pen writing function, adopts the time writer of different frequency, and is interference-free between two, can support two whiles on the blank projecting plane enterprising running hand write operation, thereby realizing that many people are mutual simultaneously uses.
