Abstract: A method includes displaying on a display at least one selection option comprising a first selection option and detecting a touch or cursor on the display. Tactile feedback having a first characteristic is provided when the touch or cursor is at a first location associated with the first selection option. Tactile feedback having a second characteristic is provided when the touch or cursor is detected at a second location not associated with the first selection option.
