A hand-held electronic device, comprising: a case having one or more major surfaces; a touch screen display disposed on at least one of the major surfaces which is operable to track a user input; a processor operably coupled to the touch screen display which is operable to determine a state of the touch screen display; and a plurality of tactile pixels surrounding the touch screen display, wherein each of the tactile pixels includes an actuatable portion coupled to an actuator and a sensor, wherein the actuator is coupled to the processor, wherein the actuator is configured to actuate in response to instructions from the processor in response to detection of a predetermined state of the touch screen display and wherein the sensor is configured to generate signals as inputs to one or more programs executed by the processor when pressure is applied to the actuatable portion, wherein the actuatable portion is actuatable by the actuator between a first and a second position in response to execution of one or more instructions by the processor, wherein a tactile feel of the actuatable portion in the first position is different from the tactile feel of the actuatable portion in the second position; characterised in that: the touch screen display is operable to display a scroll bar; the processor is operable to raise selected tactile pixels proximate the scroll bar for use as a scroll wheel, wherein the user may operate the selected tactile pixels and wherein pressing the selected tactile pixels in a particular sequence is associated as scrolling instruction; and the device is configured such that a particular one or more of the tactile pixels selectively actuate to mark an endpoint of scrolling of an image displayed on the touch screen display. a case having one or more major surfaces; a touch screen display disposed on at least one of the major surfaces which is operable to track a user input; a processor operably coupled to the touch screen display which is operable to determine a state of the touch screen display; and a plurality of tactile pixels surrounding the touch screen display, wherein each of the tactile pixels includes an actuatable portion coupled to an actuator and a sensor, wherein the actuator is coupled to the processor, wherein the actuator is configured to actuate in response to instructions from the processor in response to detection of a predetermined state of the touch screen display and wherein the sensor is configured to generate signals as inputs to one or more programs executed by the processor when pressure is applied to the actuatable portion, wherein the actuatable portion is actuatable by the actuator between a first and a second position in response to execution of one or more instructions by the processor, wherein a tactile feel of the actuatable portion in the first position is different from the tactile feel of the actuatable portion in the second position; the touch screen display is operable to display a scroll bar; the processor is operable to raise selected tactile pixels proximate the scroll bar for use as a scroll wheel, wherein the user may operate the selected tactile pixels and wherein pressing the selected tactile pixels in a particular sequence is associated as scrolling instruction; and the device is configured such that a particular one or more of the tactile pixels selectively actuate to mark an endpoint of scrolling of an image displayed on the touch screen display.
