Patent ID: 8779904

Claim:
A remote controller comprising: a touch pad; a capacitive type pressure transducer unit; a three-axis accelerometer sensor; a gyroscope; a communication unit to communicate with a remotely controlled device; and a processor to generate control signals according to the speed of the movement of the remote controller sensed by the three-axis accelerometer and the direction of the movement of the remote controller sensed by the gyroscope and transmit the control signals to the remotely controlled device when the remote controller is in a first work mode, generate the control signals according to touch sensing signals from the touch pad and transmit the control signals to the remotely controlled device when the remote controller is in a second work mode, and generate the control signals according to variations in the capacitance of the capacitive type pressure transducer unit and transmit the control signals to the remotely controlled device when the remote controller is in a third work mode, the processor further to switch operational modes between the first work mode and the second work mode according to the touch sensing signals from the touch pad, and switch operational modes between the first work mode and the third work mode according to a variation in the capacitance of the capacitive type pressure transducer unit, wherein when the remote controller is in the first work mode, if the processor determines that the variation in the capacitance of the capacitive type pressure transducer unit falls within a predetermined range, the processor is to switch the remote controller from the first work mode to the third work mode; when the remote controller is in the third work mode, if the processor determines that the variation in the capacitance of the capacitance type pressure transducer unit falls within the predetermined range, the processor is to switch the remote controller from the third work mode to the first work mode; and when the remote controller is in the third work mode, if the processor determines that the capacitance of the transducer unit does not change within a predetermined period, the processor is to switch the remote controller from the third work mode to the first work mode.
