Described method also comprises step S14 behind step S12: described information sends the coding unit of terminal and finishes the storage representation mode of the original screen coordinate of information input trajectory to the sentence of importing, individual character, stroke; Calculate and intercharacterly stay whitely, implement the convergent-divergent in the proportional range, finish the normalization of character; Thereby in step S15, described information transmitting unit will be sent to the information receiving unit of information receiving terminal through the information encoded input trajectory;
Described method also comprises step S23 behind step S21: the decoding unit of described information receiving terminal will be decoded into whole sentence through the information encoded input trajectory, sentence comprises character or/and diagram, character and diagram comprise stroke data, and stroke data comprises some tracing points and display parameter thereof;
Described method also comprises step S24 behind step S23: the decoded information input trajectory data of the tectonic element input decoding unit of described information receiving terminal, according to the width of the viewing area of current device system, highly, the shape of viewing area, the display parameter constraint of information receiving terminal configuration, construct the absolute location coordinates of whole sentence on screen.
10. information interacting method according to claim 8 is characterized in that:
Described method also comprises step S13 behind step S12: described information sends the compression unit compressed information input trajectory of terminal; Adopt " data packet length " to reach the expression mode of " packet content ", the sentence track of succinct description input adopts the compression algorithm compression then, is convenient to storage and transmission; Described information transmitting unit will be sent to the information receiving unit of information receiving terminal through the information compressed input trajectory;
Described method also comprises step S22 behind step S21: the decompress(ion) unit of described information receiving terminal will utilize decompression algorithm to decompress through the information compressed input trajectory, be expressed as the expression mode that " data packet length " reaches " packet content ".
