A mobile terminal comprising: a touch screen display comprising an information display region and at least two preset active regions (L, R) adapted to allow a user to select a screen location of at least one user interface display region (320, 322, 324) on which a particular user interface comprising first and second portions (320a, 320b) of control elements is to be displayed, wherein each of the at least two active regions (L, R) corresponds to a region selectable for the at least one user interface display region (320, 322, 324); and a controller configured to cooperate with the touch screen display to: detect a touch event occurring in at least one of the at least two active regions (L, R); when the touch event satisfies a predetermined touch condition and the touch event occurred in only one of the at least two active regions (L, R), allocate the region corresponding to the one of the at least two active regions (L, R) in which the touch event occurred as the only user interface display region and display the user interface comprising the first and second portions (320a, 320b) of control elements on the allocated user interface display region; and when the touch event satisfies the predetermined touch condition and the touch event occurred in two of the at least two active regions (L, R), allocate the regions corresponding to the two of the at least two active regions (L, R) in which the touch event occurred as first and second user interface display regions (322, 324), divide the user interface into a first user interface comprising the first portion of control elements and a second user interface comprising the second portion of control elements, and display each of the first and the second user interfaces on a corresponding one of the allocated first and second user interface display regions (322, 324). a touch screen display comprising an information display region and at least two preset active regions (L, R) adapted to allow a user to select a screen location of at least one user interface display region (320, 322, 324) on which a particular user interface comprising first and second portions (320a, 320b) of control elements is to be displayed, wherein each of the at least two active regions (L, R) corresponds to a region selectable for the at least one user interface display region (320, 322, 324); and a controller configured to cooperate with the touch screen display to: detect a touch event occurring in at least one of the at least two active regions (L, R); when the touch event satisfies a predetermined touch condition and the touch event occurred in only one of the at least two active regions (L, R), allocate the region corresponding to the one of the at least two active regions (L, R) in which the touch event occurred as the only user interface display region and display the user interface comprising the first and second portions (320a, 320b) of control elements on the allocated user interface display region; and when the touch event satisfies the predetermined touch condition and the touch event occurred in two of the at least two active regions (L, R), allocate the regions corresponding to the two of the at least two active regions (L, R) in which the touch event occurred as first and second user interface display regions (322, 324), divide the user interface into a first user interface comprising the first portion of control elements and a second user interface comprising the second portion of control elements, and display each of the first and the second user interfaces on a corresponding one of the allocated first and second user interface display regions (322, 324).
