Abstract:
1. A display screen, comprising: a first sensor array that is operable to detect when an external stimulus that meets a first detection criteria; a second sensor array 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 it only meets the first detection criteria; and a haptic feedback device coupled to the display screen which applies a first haptic feedback to the display screen in response to only the first sensor array detecting the external stimulus and which applies a second haptic feedback to the display screen, different from the first haptic feedback, in response to both the first sensor array detecting the external stimulus and the second sensor array detecting the external stimulus, wherein the first and second sensor arrays belong to different types, the different types selected from the group consisting of capacitive-sensitive arrays, resistive-sensitive arrays, proximity-sensitive arrays, sound-sensitive arrays and light-sensitive arrays, and wherein the first detection criteria comprises a first pressure that is applied against the display screen, and the second detection criteria comprises a second pressure, greater than the first pressure, that is applied against the display screen.
