The designator has a sight arranged to display, in operation, a reticule superimposed upon a field of view. The reticule is moveable within the field of view. The designator further comprises an eye tracker operable to track the gaze of the operator whilst the operator uses the sight. The eye tracker communicates with the sight such that the reticule moves so as to be aligned with the direction of the gaze of the operator. ## Claims ### Claim 1 A target designator for a guided weapon, the designator having a sight arranged to display, in operation, a reticule superimposed upon a field of view, the reticule being moveable relative to the field of view; the designator further comprising an eye tracker operable to track the gaze of the operator whilst the operator uses the sight; and the eye tracker being in communication with the sight such that the reticule moves so as to be aligned with the direction of the gaze of the operator. ### Claim 2 (depends on 1) A designator as claimed in claim 1, wherein the eye tracker is mounted on the sight. ### Claim 3 (depends on 1) A designator as claimed in claim 1, wherein the eye tracker is a wearable device. ### Claim 4 (depends on 1) A designator as claimed in claim 1, wherein the sight is a telescopic device through which the field of view is visible. ### Claim 5 (depends on 1) A designator as claimed in claim 1, wherein the guided weapon is provided with a camera, and wherein the field of view displayed by the sight is provided by the camera. ### Claim 6 (depends on 1) A designator as claimed in claim 1, wherein the eye tracker is associated with a processor configured to recognise one or more eye gestures, and to control the sight such that the field of view displayed by the sight is altered in response to the one or more eye gestures ### Claim 7 (depends on 6) A designator as claimed in claim 6, wherein one of the one or more eye gestures causes the sight to zoom in on a portion of the field of view. ### Claim 8 (depends on 6) A designator as claimed in claim 6, wherein one of the one or more eye gestures causes the sight to move the field of view. ### Claim 9 (depends on 6) A designator as claimed in claim 6, wherein one of the one or more eye gestures causes the sight to zoom out. ### Claim 10 (depends on 1) A designator as claimed in claim 1 wherein the display is configured to zoom either in or out depending on the position of the operator's gaze within the field of view. ### Claim 11 (depends on 10) A designator as claimed in claim 10 wherein the display has first and second regions, and wherein the display will zoom in when the operator's gaze lingers in a first region, and zooms out when the operator's gaze lingers in a second region. ### Claim 12 (depends on 11) A designator as claimed in claim 11 wherein the rate of zoom is dependent on a distance between the operator's gaze and the boundary between the first and second regions. ### Claim 13 (depends on 1) A designator as claimed in claim 1, further comprising a trigger device, and wherein the designator is configured such that, upon a first operation on the trigger device, the weapon selects as a target an object on which the reticule is centred. ### Claim 14 (depends on 1) A designator as claimed in claim 1, wherein the designator is configured to detect when the operator's gaze settles on a particular object for longer than a predetermined period of time, and to designate that object to the guided weapon as a target. ### Claim 15 (depends on 1) A designator as claimed in claim 1, wherein the designator comprises communication means for communicating with a remote weapon such that a target can be designated to the remote weapon. ### Claim 16 (depends on 1) A target designator as claimed in claim 1, wherein the designator is a handheld target designator. ### Claim 17 (depends on 1) A handheld launcher for a guided weapon comprising a designator as claimed in claim 1. ### Claim 18 (canceled)
