Input means for interactive devices

input means for an interactive device, comprising:

• a first accelerometer detecting a first linear movement along a first axis;
• a second accelerometer detecting a second linear movement along said first axis;
• a third accelerometer detecting a third linear movement along a second axis and a first rotational movement around said first axis
• a keypad, having a key to be selected and pressed for generating a selecting signal accordingly;
• a control unit, fetching the selecting signal, the first linear movement, said second linear movement, said third linear movement, and said first rotational movement, calculates a second rotational movement around a third axis based on said first linear movement and said second linear movement, and generating a control signal corresponding thereto;
• a signal processing unit, for receiving and processing the control signal transmitted from the control unit so as to generate an interactive signal encoded for the interactive device and then sending the interactive signal back to the control unit;
• and
• a wireless transmission module, being used to transmit the interactive signal from the control unit to the interactive device.
