Abstract: In the touch panel device, when a slide operation in an oblique direction by a user is performed, out of a content displayed on the display screen 11 at that time, a region surrounded by an imaginary rectangle in which a start point Pa and an end point Pb of the slide operation are opposing corners and either one side of the imaginary rectangle is parallel to either one side of the display screen is displayed in an enlarged manner so as to fill the entirety of the predetermined region 12 of the display screen 11. With this, an intuitive display enlargement operation can be performed even for a touch panel device not supporting a multi-touch operation.

Abstract: Feedback control of an object which moves back and forth in a straight line along a linear guide is performed through PID control. A parameter adjustment unit which determines the control parameters to be used for PID control performs feedback control and determines the optimal value of control parameters by means of an evaluation function based on the error between the measured value of the current velocity and the target velocity, for the control parameters of maximum reverse voltage and at least one from among proportional coefficient (CP), differential coefficient CD), integral coefficient CI), and frictional coefficient (CF).
