A display apparatus for a vehicle, comprising: a display unit; a gesture sensing unit configured to sense a 3D gesture made by an object in front of the display unit; and a processor configured to control, based on the 3D gesture made by the object, the display unit, wherein the gesture sensing unit includes: a first light-emitting unit configured to emit a first group of rays along a first path into a near field, wherein the near field is defined within a first distance from the display unit, a second light-emitting unit configured to emit a second group of rays along a second path into a far field, wherein the far field is defined between the first distance and a second distance from the display unit, wherein the second distance is greater than the first distance, and a light-receiving unit configured to receive (i) reflected rays of the first group of rays that are reflected from the object and (ii) reflected rays of the second group of rays that are reflected from the object, wherein the processor is further configured to control the first light-emitting unit to output the first group of rays for a first time period and to control the second light-emitting unit to output the second group of rays for a second time period and to detect, based on the reflected rays of the first group of rays or the reflected rays of the second group of rays, the 3D gesture of the object, and wherein the processor is configured to provide a first control signal when the second group of reflected rays is received in a state in which a prescribed menu or item is highlighted on the display unit, and to provide a second control signal when the first group of reflected rays and the second group of reflected rays are received in a state in which a prescribed menu or item is highlighted on the display unit. a display unit; a gesture sensing unit configured to sense a 3D gesture made by an object in front of the display unit; and a processor configured to control, based on the 3D gesture made by the object, the display unit, wherein the gesture sensing unit includes: a first light-emitting unit configured to emit a first group of rays along a first path into a near field, wherein the near field is defined within a first distance from the display unit, a second light-emitting unit configured to emit a second group of rays along a second path into a far field, wherein the far field is defined between the first distance and a second distance from the display unit, wherein the second distance is greater than the first distance, and a light-receiving unit configured to receive (i) reflected rays of the first group of rays that are reflected from the object and (ii) reflected rays of the second group of rays that are reflected from the object, a first light-emitting unit configured to emit a first group of rays along a first path into a near field, wherein the near field is defined within a first distance from the display unit, a second light-emitting unit configured to emit a second group of rays along a second path into a far field, wherein the far field is defined between the first distance and a second distance from the display unit, wherein the second distance is greater than the first distance, and a light-receiving unit configured to receive (i) reflected rays of the first group of rays that are reflected from the object and (ii) reflected rays of the second group of rays that are reflected from the object, wherein the processor is further configured to control the first light-emitting unit to output the first group of rays for a first time period and to control the second light-emitting unit to output the second group of rays for a second time period and to detect, based on the reflected rays of the first group of rays or the reflected rays of the second group of rays, the 3D gesture of the object, and wherein the processor is configured to provide a first control signal when the second group of reflected rays is received in a state in which a prescribed menu or item is highlighted on the display unit, and to provide a second control signal when the first group of reflected rays and the second group of reflected rays are received in a state in which a prescribed menu or item is highlighted on the display unit.
