The present invention relates to a device to obtain ground information by being held by a user or worn on the body or clothes. According to the present invention, slope information is generated by correcting a slope value measured when a user stops moving so as to prevent an error due to a movement at a time of measuring the slope; thus obtaining the correct slope value. Since the ground information is able to be obtained in a state wearing on a part of the body or clothes of the user, the device is conveniently held by the user; and since no time is required for installation, moving, or dismantling the device not required, ground information is able to quickly be obtained. Moreover, since error in the slope value generated in a mounting area is able to be correct, an effect of allowing installation in various positions when necessary is provided. The device comprises: a communication module; a movement determining module; a slope information generating module; a storage module; and a control module. |
