Abstract: A dual-mode tablet and a detecting and switching method for input signals thereof are provided. The dual-mode tablet includes an electromagnetic induction module and a touch input module. The microprocessor controls the electromagnetic induction module to electronically connect to an induction coil group and detects whether any electromagnetic signal is received.

When the microprocessor receives a touch input signal, the microprocessor alternately controls one of the electromagnetic induction module and the touch input module to electronically connect to the induction coil group. When the microprocessor detects one electromagnetic signal is received, the electromagnetic induction module electronically connects to the induction coil group continuously until the electromagnetic signal is received completely.

Abstract: A method for operating an electret input device includes the following steps. An input signal is received. It is determined whether a voltage level of the input signal is greater than a first preset value. If the voltage level is greater than the first preset value, the voltage level is compared with a second preset value to determine whether the input signal is an effective signal. If the input signal is the effective signal, the position value of the input signal is obtained. Then, the position value is compared with a preset position value to determine an input state of the electret input device. Finally, the input signal is converted to an output signal to be outputted.
