Definitions

  • it further includes: entering a power-saving mode from a working mode when the input device detects the electronic board eraser being in still for a period, retrieving the working mode from the power-saving mode when the input device detects the electronic board eraser being moved.
  • a frequency of the sensing circuit sensing the beacon signal in the power-saving mode is slower than that of the sensing circuit sensing the beacon signal in the working mode.
  • each of the eraser electrodes 341 - 344 emits an electrical signal representing the pressure received by itself.
  • the variations of the technical solutions shown in the relevant embodiments of FIGS. 7A-7B of US2015/0153845 can be used.
  • each of the eraser electrodes 341 - 344 in time-sharing manner emits a modulated electrical signal, which indicates the pressure value received by the respective eraser electrode.
  • step 820 having a driving circuit of the electronic board eraser provide electrical signals to at least three eraser electrodes of the electronic board eraser after a time period since the beacon signal is emitted.
  • the electrical signals' modulation method includes one of the following: emitting a same frequency set of electrical signals via the at least three eraser electrodes sequentially in time-sharing manner; emitting status messages via one of or multiple the eraser electrodes simultaneously; emitting different frequency sets of electrical signals via at least two of the eraser electrodes simultaneously; and emitting two different frequency sets of electrical signals via the at least three eraser electrodes sequentially in time-sharing manner.
