A method, apparatus, user interface and computer program product for using a device to detect a signal corresponding to a sliding input on a touch sensitive area of the device, the sliding input being for a time setting adjustment. A time unit corresponding to a start point of the sliding input is determined, and if the signal indicates that the sliding input is substantially in a first direction, a time setting of the corresponding time unit is increased by a pre-defined increment, and if the signal indicates that the sliding input is substantially in a second direction, the time setting of the corresponding time unit is decreased by a pre-defined increment. Feedback signals are provided at regular intervals of length, along the route of the sliding movement. Those feedback signals can be sensed or felt, which helps in using the device without looking all the time at the screen, which enables the eyes-free-operation of the device for most time settings, so that they can be made with a single hand; with the thumb of the hand which holds the device.
