Abstract: The present invention relates to a method for processing information, an information processing system, and a handwriting input terminal. Said information processing system can operate in a handwriting input mode or a click input mode. Such system comprises a plurality of handwriting input terminals, and a data processing center communicatively connected with handwriting input terminals via a transceiver. Said method comprises following steps: S1: configuring a handwriting recognition module and a click position coordinate-key mapping module for the information processing system; S2: receiving information about working mode selection of the information processing system; S3: the handwriting input terminal receives and processes handwriting input signals to obtain coordinate information; S4: selecting the handwriting recognition module or click position coordinate-key mapping module to transform the coordinate information into corresponding character or key information based on the selected working mode.

Abstract: A large screen information interactive system and method are disclosed, including a computer 3, a projector 4, a pointer equipment 2, and an interactive whiteboard 1 including at least one display panel 6 on the same plane and at least one electronic writing board 5 used for sensing and receiving an operational signal of the pointer equipment 2. The at least one electronic writing board 5 is connected with the computer 3 through a serial port, a USB port, a wireless communication module, or a bluetooth module. The signal of the pointer equipment 2 collected from the electronic writing board 5 is processed by the computer 3. A processed displayed image is projected onto the interactive whiteboard 1 by the projector 4. When one point on the electronic writing board 5 is written, position and state information signals of the written point are transferred to the computer for converting, and the data is processed according to display attributes and operational commands.

Abstract: The present invention relates to an electronic pen using a super capacitor as a power supply which comprising a housing, a power supply, and a nib arranged at one end of the housing, a boosting circuit connected with the power supply for implementing a boosting process to an output voltage of the power supply based on an external triggering signal, an oscillation circuit for generating electromagnetic waves with different frequencies based on the voltage provided by the boosting circuit, wherein, the power supply is a super capacitor. By using a super capacitor as a power supply, the present invention brings no pollutions in the constitution of the raw material, and in the processes of production, using, storing and disassembling, so it is a perfect environmentally friendly power supply. Moreover, the super capacitor can be recycling used, so the cost is greatly reduced. Using the super capacitor as a power supply, the charging rate is fast, only several minutes even tens of seconds are needed for charging.
