A display screen (100; 200; 300; 500), comprising: a first sensor array (102; 210; 430; 540) that is operable to detect when an external stimulus meets a first detection criteria, wherein the first sensor array is a planar, capacitive sensor array overlaying the display screen; a second sensor array (104; 220; 420; 550-570) that is operable to detect when the external stimulus meets a second detection criteria, the second detection criteria quantitatively different from the first detection criteria, wherein the external stimulus is detectable when the external stimulus meets both the first detection criteria and the second detection criteria and when the external stimulus only meets the first detection criteria, wherein the second sensor array is a planar, resistive sensor array which overlays the display screen and is disposed in substantially the same plane as the first sensor array; and a plurality of haptic feedback devices (240; 330) including actuators coupled to the display screen which applies a first haptic feedback to the display screen in response to the first sensor array (102; 210; 430; 540) detecting the external stimulus and which applies a second haptic feedback to the display screen (100; 200; 300; 500), different from the first haptic feedback, in response to both the first sensor array (102; 210; 430; 540) detecting the external stimulus and the second sensor array (104; 220; 420; 550-570) detecting the external stimulus, wherein the first detection criteria comprises a first pressure that is applied against the display screen (100; 200; 300; 500), and the second detection criteria comprises a second pressure that is applied against the display screen (100; 200; 300; 500), the second pressure greater than the first pressure. a first sensor array (102; 210; 430; 540) that is operable to detect when an external stimulus meets a first detection criteria, wherein the first sensor array is a planar, capacitive sensor array overlaying the display screen; a second sensor array (104; 220; 420; 550-570) that is operable to detect when the external stimulus meets a second detection criteria, the second detection criteria quantitatively different from the first detection criteria, wherein the external stimulus is detectable when the external stimulus meets both the first detection criteria and the second detection criteria and when the external stimulus only meets the first detection criteria, wherein the second sensor array is a planar, resistive sensor array which overlays the display screen and is disposed in substantially the same plane as the first sensor array; and a plurality of haptic feedback devices (240; 330) including actuators coupled to the display screen which applies a first haptic feedback to the display screen in response to the first sensor array (102; 210; 430; 540) detecting the external stimulus and which applies a second haptic feedback to the display screen (100; 200; 300; 500), different from the first haptic feedback, in response to both the first sensor array (102; 210; 430; 540) detecting the external stimulus and the second sensor array (104; 220; 420; 550-570) detecting the external stimulus, wherein the first detection criteria comprises a first pressure that is applied against the display screen (100; 200; 300; 500), and the second detection criteria comprises a second pressure that is applied against the display screen (100; 200; 300; 500), the second pressure greater than the first pressure.
