Abstract

An apparatus and a method for entering information into an electronic device are provided. The apparatus (200) includes five text-input buttons (102, etc) that can be activated by pressing or by touching. In one embodiment, the buttons are located on a disk (302). Text is entered by pressing or touching a single text-input button and then passing a finger or thumb over additional buttons in a prescribed order. The apparatus may be used in conjunction with additional input devices, such as an ‘accept’ or ‘OK’ button. Four navigation buttons (104, etc) are also provided. In one embodiment, these are additional buttons. In a further embodiment, four of the five text-input buttons are selectable as navigation buttons. The selection may be achieved by rotation of the disk (302) on which the buttons are located. The apparatus may also include a rotatable wheel or roller (108) to permit scrolling through lists. The apparatus may be used to enter navigation (command), text or number information.
