An information terminal (1, 101∼105, 201), comprising: a first housing and a second housing interconnected for opening/closure; a first display unit (31, 81) and a first touch panel (30, 80) stacked one upon the other on the first housing; a second display unit (41, 91) and a second touch panel (40, 90) stacked one upon the other on the second housing; a detection unit which, in a closed state with the first and second display units (31, 81; 41, 91) being superposed one upon the other and facing outwards, is configured to detect actuations on one of the first touch panel (30, 80) and the second touch panel (40, 90) that is back-facing as seen from a user; a controller that is configured to control an onscreen display on one of the first display unit (31, 81) and the second display unit (41, 91) that is front-facing as seen from the user, based on information regarding the actuations detected by the detection unit; characterised by means for registering information on the handedness of the user received by the user or for storing past information regarding the loci of finger movements on the second touch panel (40, 90) to automatically determine the handedness of the user from the so stored information, wherein each of the first and second housings (11; 12) includes an actuation key; wherein the controller is configured to determine the first or second housing (11; 12), inputting to which by the actuation key has been detected in the closed state, as being the front-facing housing; wherein the controller controls onscreen display of the display unit that is front-facing based on information regarding the actuations detected from a specified area of the touch panel which is back-facing; the controller not using the information regarding the actuations detected in an area other than the specified area in controlling onscreen display; and wherein the range of actuation on the touch panel which is back-facing is restricted to a preset range depending on the handedness of the user. a first housing and a second housing interconnected for opening/closure; a first display unit (31, 81) and a first touch panel (30, 80) stacked one upon the other on the first housing; a second display unit (41, 91) and a second touch panel (40, 90) stacked one upon the other on the second housing; a detection unit which, in a closed state with the first and second display units (31, 81; 41, 91) being superposed one upon the other and facing outwards, is configured to detect actuations on one of the first touch panel (30, 80) and the second touch panel (40, 90) that is back-facing as seen from a user; a controller that is configured to control an onscreen display on one of the first display unit (31, 81) and the second display unit (41, 91) that is front-facing as seen from the user, based on information regarding the actuations detected by the detection unit; characterised by means for registering information on the handedness of the user received by the user or for storing past information regarding the loci of finger movements on the second touch panel (40, 90) to automatically determine the handedness of the user from the so stored information, wherein each of the first and second housings (11; 12) includes an actuation key; wherein the controller is configured to determine the first or second housing (11; 12), inputting to which by the actuation key has been detected in the closed state, as being the front-facing housing; wherein the controller controls onscreen display of the display unit that is front-facing based on information regarding the actuations detected from a specified area of the touch panel which is back-facing; the controller not using the information regarding the actuations detected in an area other than the specified area in controlling onscreen display; and wherein the range of actuation on the touch panel which is back-facing is restricted to a preset range depending on the handedness of the user.
