Claim Text:
1. A function driving apparatus comprising: an acceleration sensor which detects acceleration components of a device in directions of x axis, y axis, and z axis which are orthogonal to each other, at predetermined time intervals; and a control section which transforms, at predetermined time intervals, the acceleration components detected by the acceleration sensor to polar coordinate components formed of an r component representing a distance from an origin of an xyz space, a θ component representing an angle formed with the x axis, and a φ component representing an angle formed with an xy plane including the x axis and the y axis, and drives a specific function of the device when a state in which the θ component and the φ component are within a predetermined set range continues for a predetermined time or longer, wherein the control section judges whether the θ component or the φ component is within the predetermined set range, at predetermined time intervals; increments a first coefficient when the θ component and the φ component are within the predetermined set range; increments a second coefficient and decrements the first coefficient when the θ component or the φ component is out of the predetermined set range; and drives the specific function of the device based on a result of comparison between the first coefficient and a first preset value.
