A method of operating a portable terminal, the portable terminal comprising: a touch pad that is configured to display one or more icons in a first region and to detect a touch in a second region, wherein a part of the touch pad is preset as the second region dedicated for touch and the one or more icons are not displayed in the second region of the touch pad; the method comprising: imaging, by a camera (120, 130) of the portable terminal, a face of a user of the portable terminal; detecting, by a detecting unit of the portable terminal, a point of view on the touch pad to which an eye of the face of the user imaged by the camera (120, 130) is turned, wherein the point of view is not detected in the preset second region of the touch pad; outputting, by an information management unit of the portable terminal, a position of the point of view detected by the detecting unit; performing, by a cursor display unit of the portable terminal, control such that a cursor is displayed on the touch pad according to the position of the point of view on the touch pad output from the information management unit; determining, by an input condition management unit of the portable terminal, whether or not a preset input condition is satisfied for an input by a touch to the preset second region of the touch pad and an input of the position of the point of view on the touch pad output from the information management unit; and activating, by an application program executing unit of the portable terminal, an application program corresponding to an icon of the one or more icons of the position of the point of view on the touch pad from the information management unit according to the determination of the input condition management unit for the inputting to the second region and the inputting of the position of the point of view on the first region. a touch pad that is configured to display one or more icons in a first region and to detect a touch in a second region, wherein a part of the touch pad is preset as the second region dedicated for touch and the one or more icons are not displayed in the second region of the touch pad; the method comprising: imaging, by a camera (120, 130) of the portable terminal, a face of a user of the portable terminal; detecting, by a detecting unit of the portable terminal, a point of view on the touch pad to which an eye of the face of the user imaged by the camera (120, 130) is turned, wherein the point of view is not detected in the preset second region of the touch pad; outputting, by an information management unit of the portable terminal, a position of the point of view detected by the detecting unit; performing, by a cursor display unit of the portable terminal, control such that a cursor is displayed on the touch pad according to the position of the point of view on the touch pad output from the information management unit; determining, by an input condition management unit of the portable terminal, whether or not a preset input condition is satisfied for an input by a touch to the preset second region of the touch pad and an input of the position of the point of view on the touch pad output from the information management unit; and activating, by an application program executing unit of the portable terminal, an application program corresponding to an icon of the one or more icons of the position of the point of view on the touch pad from the information management unit according to the determination of the input condition management unit for the inputting to the second region and the inputting of the position of the point of view on the first region. imaging, by a camera (120, 130) of the portable terminal, a face of a user of the portable terminal; detecting, by a detecting unit of the portable terminal, a point of view on the touch pad to which an eye of the face of the user imaged by the camera (120, 130) is turned, wherein the point of view is not detected in the preset second region of the touch pad; outputting, by an information management unit of the portable terminal, a position of the point of view detected by the detecting unit; performing, by a cursor display unit of the portable terminal, control such that a cursor is displayed on the touch pad according to the position of the point of view on the touch pad output from the information management unit; determining, by an input condition management unit of the portable terminal, whether or not a preset input condition is satisfied for an input by a touch to the preset second region of the touch pad and an input of the position of the point of view on the touch pad output from the information management unit; and activating, by an application program executing unit of the portable terminal, an application program corresponding to an icon of the one or more icons of the position of the point of view on the touch pad from the information management unit according to the determination of the input condition management unit for the inputting to the second region and the inputting of the position of the point of view on the first region.
