<p>A device with a display is provided with a first touch pad on the front face of the device and a second touch pad on the rear face. When an operation is performed only on the first touch pad, the process allocated to the point of contact or the pattern of movement thereof is identified and executed. When both the first and second touch pads are used for operation, the process defined to correspond to a combination of modes of movement of the points of contact is identified and executed. When an operation is performed only on the second touch pad, only the component of the movement of the point of contact in a limited direction is extracted to calculate the amount of scrolling, and a scroll process is performed accordingly.</p> |
