Patent ID: 8810362

Claim:
A recognition system, for recognizing an operation of a user, comprising: a sensor module, for generating a first sensing signal according to the operation of the user when detecting the presence of the user, wherein the operation of the user includes the user's voice or movement, and the sensor module comprises: a primary sensor device, for recognizing the operation of the user and generating the first sensing signal; and a secondary sensor device, for recognizing a response of the user and generating a second sensing signal; a data storage device, for storing a plurality of objects; a processing device, for comparing the first sensing signal and the plurality of objects to generate only one recognition result in response to the first sensing signal; and a playing device, for playing the recognition result; wherein after the recognition result is played, the sensor module is used for feeding the second sensing signal back to the processing device, and the processing device judges whether the recognition result is acceptable by analyzing the second sensing signal; and wherein the secondary sensor device is a physiological signal sensor used for detecting a physiological signal of an involuntary response, so as to avoid a cheating behavior of the user.
