A system (100; 300) comprising: a detector (110; 110';110") configured to determine a direction of an eye gaze of a user of the system relative to a display device; a processor (120; 114; 118; 410; 520; 820) configured to: determine one or more parameters of a first haptic effect associated with the direction of the user's eye gaze being towards the display device; determine one or more parameters of a second haptic effect associated with the direction of the user's eye gaze being away from the display device, wherein the second haptic effect is different from the first haptic effect and the one or more parameters of the first and second haptic effects are selected from the group comprising: an amplitude; a frequency; or a duration; generate a first signal representative of the first haptic effect when an event occurs on the display device and the eye gaze of the user is determined to be directed towards the display device; and generate a second signal representative of the second haptic effect when the event occurs on the display device and the eye gaze of the user is determined to be directed away from the display device; and a haptic output device (130; 530; 830) configured to receive the first signal and second signal from the processor and output the first haptic effect or the second haptic effect. a detector (110; 110';110") configured to determine a direction of an eye gaze of a user of the system relative to a display device; a processor (120; 114; 118; 410; 520; 820) configured to: determine one or more parameters of a first haptic effect associated with the direction of the user's eye gaze being towards the display device; determine one or more parameters of a second haptic effect associated with the direction of the user's eye gaze being away from the display device, wherein the second haptic effect is different from the first haptic effect and the one or more parameters of the first and second haptic effects are selected from the group comprising: an amplitude; a frequency; or a duration; generate a first signal representative of the first haptic effect when an event occurs on the display device and the eye gaze of the user is determined to be directed towards the display device; and generate a second signal representative of the second haptic effect when the event occurs on the display device and the eye gaze of the user is determined to be directed away from the display device; and determine one or more parameters of a first haptic effect associated with the direction of the user's eye gaze being towards the display device; determine one or more parameters of a second haptic effect associated with the direction of the user's eye gaze being away from the display device, wherein the second haptic effect is different from the first haptic effect and the one or more parameters of the first and second haptic effects are selected from the group comprising: an amplitude; a frequency; or a duration; generate a first signal representative of the first haptic effect when an event occurs on the display device and the eye gaze of the user is determined to be directed towards the display device; and generate a second signal representative of the second haptic effect when the event occurs on the display device and the eye gaze of the user is determined to be directed away from the display device; and a haptic output device (130; 530; 830) configured to receive the first signal and second signal from the processor and output the first haptic effect or the second haptic effect.
