The object detector detects a position of an object inside a field of view (FOV) of the object detector. The processor splits the FOV into one or more FOV sectors based on one or more options on a display. Further, the processor maps each of the one or more options uniquely to an FOV sector of the one or more FOV sectors. The processor further controls a movement of a pointer on the display to point to an option of the one or more options of which the mapped FOV sector includes the detected position of the object, thereby enabling contactless control of the display. ## Claims ### Claim 1 An apparatus, comprising: an object detector configured to detect a position of an object with respect to the object detector; and a processor that is coupled to the object detector, and configured to: split a field of view (FOV) of the object detector into one or more FOV sectors based on one or more options on a display; map each of the one or more options uniquely to an FOV sector of the one or more FOV sectors; and control a movement of a pointer on the display to point to a first option of the one or more

3) The apparatus of claim 3, wherein the FOV comprises a horizontal angle range and a vertical angle range of the object detector, wherein to split the FOV into the one or more FOV sectors, the processor is further configured to split the horizontal angle range into one or more horizontal angle sub-ranges and the vertical angle range into one or more vertical angle sub-ranges, based on the one or more options, and wherein each FOV sector of the one or more FOV sectors comprises a unique combination of a horizontal angle sub-range of the one or more horizontal angle sub-ranges and a vertical angle sub-range of the one or more vertical angle sub-ranges. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the one or more options are arranged on the display in one or more rows and one or more columns. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the processor splits (i) the horizontal angle range into the one or more horizontal angle sub-ranges based on a count of the one or more columns in which the one or more options are arranged on the display, and (ii) the vertical angle range into the one or more vertical angle sub-ranges based on a count of the one or more rows in which the one or more options are arranged on the display. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the processor is further configured to control the movement of the pointer on the display to shift the pointer from the first option to a second option of the one or more options based on a change in the position of the object in at least one of a group consisting of a horizontal plane and a vertical plane. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the one or more options include one or more graphical user interface (GUI) elements. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the one or more options include at least one of a group consisting of a left scroll option, a right scroll option, an upward scroll option, and a downward scroll option, and wherein the processor is further configured to perform one of a group consisting of (i) a left scroll action on the display when the first option corresponds to the left scroll option, (ii) a right scroll action on the display when the first option corresponds to the right scroll option, (iii) an upward scroll action on the display when the first option corresponds to the upward scroll option, and (iv) a downward scroll action on the display when the first option corresponds to the downward scroll option. ### Claim 10 (depends on 1) The

detector among the plurality of objects. ### Claim 15 (depends on 1) The apparatus of claim 1, wherein the apparatus is a plug-and-play apparatus that interfaces with the display and functions as a
