Abstract
A signal processing apparatus includes a frequency detector configured to receive a user input including at least one of a vibration input and a user voice, vibrate in response to the received user input, and detect a frequency of the received user input, based on the vibration, and a processor configured to determine a type of the user input received by the frequency detector, based on the frequency detected by the frequency detector, and perform a function corresponding to the user input of the determined type.
Claims15
A signal processing apparatus comprising:
- a frequency detector configured to:
- receive a user input comprising at least one of a vibration input and a user voice;
- vibrate in response to the received user input;
- and
- detect a frequency of the user input, based on the vibration;
- and
- a processor configured to:
- determine a type of the user input received by the frequency detector, based on the frequency detected by the frequency detector;
- and
- perform a function corresponding to the user input of the determined type,
- wherein the processor is further configured to:
- determine that the type of the received user input is the vibration input when the detected frequency is in a first frequency band, the vibration input being a touch input comprising at least one of a tap input and a swipe input;
- determine that the type of the received user input is the user voice when the detected frequency is in a second frequency band and when the received user input lasts longer than a first length of time;
- and
- determine that the type of the received user input is noise when the detected frequency is in the second frequency band and when the received user input lasts less than the first length of time,
- wherein the processor is further configured to determine that the type of the received user input is the user voice when the first frequency band and the second frequency band overlap with each other, and the detected frequency of the received user input changes from being included in the first frequency band to a portion of the second frequency band not overlapping the first frequency band over time.
