(2) follow according to these tracks, distinguish (this technology is existing), draw these track corresponding character through relevant algorithm.
The second, be elaborated in conjunction with specific embodiment of the utility model:
See also shown in Figure 2ly, this signal generator unit comprises several (n＞10) conducting wire 22,23,24,25,26,27,28 and 29, is printed on the film 21, is arranged as lattice-shaped.
See also shown in Figure 3ly, this signal receives pen device, comprises a cylindrical shell 31 and is nested in the signal receiving circuit of these cylindrical shell 31 inside, and this signal receiving circuit comprises signal processing unit 32 and induction of signal unit 33.
Consult shown in Figure 3, when pen is clicked point reader or the teaching material above the point reader, signal receives a circuit and starts working, location MCU begins to produce magnetic field to the conductive film output signal on the point reader, the coil cutting magnetic line of induction of signal unit 33 produces induced voltage signal in the signal receiving circuit, this voltage signal is through the buffering of signal processing unit 32, amplify, behind the rectifying and wave-filtering, be linked into location MCU by communication interface in wireless or wired mode, location MCU determines the particular location coordinate that pen is clicked according to the signal of all leads of conductive film of receiving after by a series of calculation process.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
