Mobile device and method for identifying location thereof

A mobile device location identifying method for identifying a location of a mobile device in relation to a user, used in the mobile device including an operation input unit which receives an input of operation information entered by the user and a sensor unit which detects speed information regarding the mobile device, said mobile device location identifying method comprising:

• determining, as an operation reference point, a reference point corresponding to the operation information received by the operation input unit with reference to reference point rules each of which indicates a relationship between the operation information and the reference point which indicates the location of the mobile device at a point in time when the input of the operation information is received;
• calculating a movement trajectory of the mobile terminal, based on the speed information detected by the sensor unit;
• and
• identifying a location of an end point of the movement trajectory originating at a start point that is a point corresponding to the operation reference point, using the movement trajectory calculated in said calculating.

A program for identifying a location of a mobile device in relation to a user, in the mobile device including an operation input unit which receives an input of operation information entered by the user and a sensor unit which detects speed information regarding the mobile device, said program causing a computer to execute:

• determining, as an operation reference point, a reference point corresponding to the operation information received by the operation input unit with reference to reference point rules each of which indicates a relationship between the operation information and a reference point which indicates the location of the mobile device at a point when the input of the operation information is received;
• calculating a movement trajectory of the mobile terminal, based on the speed information detected by the sensor unit;
• and
• identifying a location of an end point of the movement trajectory originating at a start point that is a point corresponding to the operation reference point, using the movement trajectory calculated in the calculating.
