Abstract

A function activating apparatus includes a correspondence storage unit, an operation detecting unit, a feature-amount calculating unit, an encoded-information generating unit, a function retrieving unit, and a function activating unit. The correspondence storage unit stores a correspondence between encoded information and a function to be activated in response to input of biometric information formed of time-series image data. The operation detecting unit detects, from the time-series image data, at least one of the moving direction and acceleration of the input operation of the biometric information. The feature-amount calculating unit calculates the feature amount of at least one of the moving direction and acceleration. The encoded-information generating unit assigns a predetermined code to the feature amount. The function retrieving unit retrieves from the correspondence storage unit a function associated with the encoded information. The function activating unit activates the function.

Claims

1. A function activating apparatus comprising:

a correspondence storage unit that stores therein a correspondence between encoded information and a function to be activated in response to input of biometric information formed of time-series image data, the encoded information being obtained by encoding a feature amount of at least one of a moving direction and acceleration of input operation of biometric information;

an operation detecting unit that detects, from the time-series image data input with the input operation of the biometric information, at least one of the moving direction and acceleration of the input operation of the biometric information;

a feature-amount calculating unit that calculates the feature amount of at least one of the moving direction and acceleration detected by the operation detecting unit;

an encoded-information generating unit that assigns a predetermined code to the feature amount calculated by the feature-amount calculating unit to generate the encoded information;

a function retrieving unit that retrieves from the correspondence storage unit a function associated with the encoded information generated by the encoded-information generating unit; and

a function activating unit that activates the function retrieved by the function retrieving unit.

2. The function activating apparatus according to claim 1, wherein the operation detecting unit detects at least one of the moving direction and acceleration of the input operation from the time-series image data superposed at a position where a correlation value between pieces of the time-series image data forming the biometric information is highest.

3. The function activating apparatus according to claim 1, further comprising a biometric-information authenticating unit that authenticates the biometric information formed of the time-series image data input with the input operation of the biometric information, wherein

when the biometric information is authenticated by the biometric-information authenticating unit, the function activating unit activates the function retrieved by the function retrieving unit.

4. The function activating apparatus according to claim 3, wherein

the correspondence storage unit stores therein a correspondence among the encoded information, the function, and a body-part type corresponding to the biometric information input with the input operation of the biometric information, and

the function retrieving unit retrieves from the correspondence storage unit a function associated with the encoded information and the body-part type corresponding to the biometric information authenticated by the biometric-information authenticating unit.

5. The function activating apparatus according to claim 1, further comprising an in-function operation storage unit that stores therein a correspondence between operation that is performed in each function being activated and the encoded information, wherein

the function retrieving unit retrieves from the in-function operation storage unit the operation associated with the encoded information, and

the function activating unit performs the operation retrieved by the function retrieving unit.

6. A function activating method comprising:

detecting, from time-series image data input with input operation of biometric information, at least one of a moving direction and acceleration of the input operation of the biometric-information;

calculating a feature amount of at least one of the moving direction and acceleration detected at the detecting;

generating encoded information by assigning a predetermined code to the feature amount calculated at the calculating;

retrieving a function associated with the encoded information generated at the generating from a correspondence storage unit that stores therein a correspondence between encoded information and a function to be activated in response to input of biometric information formed of time-series image data, the encoded information being obtained by encoding a feature amount of at least one of a moving direction and acceleration of input operation of biometric information; and

activating the function retrieved at the retrieving.

7. A computer readable storage medium comprising code that, when executed, causes a computer to perform:

detecting, from time-series image data input with input operation of biometric information, at least one of a moving direction and acceleration of the input operation of the biometric-information;

calculating a feature amount of at least one of the moving direction and acceleration detected at the detecting;

generating encoded information by assigning a predetermined code to the feature amount calculated at the calculating;

retrieving a function associated with the encoded information generated at the generating from a correspondence storage unit that stores therein a correspondence between encoded information and a function to be activated in response to input of biometric information formed of time-series image data, the encoded information being obtained by encoding a feature amount of at least one of a moving direction and acceleration of input operation of biometric information; and

activating the function retrieved at the retrieving.
