Portable electronic apparatus, user interface controlling method, and program

A controlling method comprising the steps of:

• determining whether a pattern of shaking operation is performed on a main body of an apparatus in a predetermined axial direction based on whether a motion-added acceleration value in said predetermined axial direction is determined to exceed a predetermined value, wherein said motion-added acceleration value is an acceleration value obtained by adding up a predetermined number of acceleration values recently acquired in said predetermined axial direction at constant intervals;
• and
• controlling said apparatus to perform a predetermined action if said shaking operation is determined to occur in the shaking operation determining step.

A non-transitory recording medium which records a program in a manner readable by a computer, said program when executed causing said computer to execute a procedure comprising the steps of:

• determining whether a shaking operation is performed on a main body of an apparatus in a predetermined axial direction based on whether a motion-added acceleration value in said predetermined axial direction is determined to exceed a predetermined value, wherein said motion-added acceleration value is an acceleration value obtained by adding up a predetermined number of acceleration values recently acquired in said predetermined axial direction at constant intervals;
• and
• controlling said apparatus to perform a predetermined action if said shaking operation is determined to occur in the shaking operation determining step.

An electronic apparatus comprising:

• a control device configured to determine whether a reciprocal shaking operation is performed on a main body of said electronic apparatus in a predetermined axial direction based on whether a reciprocal motion is sensed within a predetermined time period in said predetermined axial direction, wherein said reciprocal shaking operation is sensed based on a change pattern in which a gradual increase in an absolute value of acceleration is observed in a negative direction during an initial take-back period followed by an abrupt surge of acceleration in a positive direction during a subsequent release period;
• and
• wherein said control device is further configured to control said electronic apparatus to perform a predetermined action if said reciprocal shaking motion is determined to occur by said control device.
