The electronic apparatus includes a motion input unit configured to receive a user motion, a display configured to display an object controlled by the user motion received by the motion input unit, and a controller configured to change a display state of the object in response to the input user motion satisfying a predetermined condition with respect to a motion recognition scope. ## Claims ### Claim 1 An electronic apparatus comprising: a motion input unit configured to receive a user motion; a display configured to display an object controlled by the user motion received by the motion input unit; and a controller configured to change a display state of the object in response to the input user motion satisfying a predetermined condition with respect to a motion recognition scope. ### Claim 2 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the controller is further configured to change at least one of a color, a transparency, and a shape of the object displayed by the display in response to the user motion entering into an area within a scope of a recognition limit, wherein the area is further configured to be predetermined to be inside the motion recognition scope with respect to a border of the motion recognition scope. ### Claim 3 (depends on 2) The electronic apparatus as claimed in claim 2, wherein the controller is further configured increase a transparency of the object displayed by the display in response to the input user motion moving in a direction closer to the border of the motion recognition scope within the scope of the recognition limit. ### Claim 4 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the controller is further configured to remove the object from being displayed by the display in response to the input user motion going beyond the motion recognition scope. ### Claim 5 (depends on 1) The electronic apparatus as claimed in claim 1, further comprising: an audio output unit, wherein the controller is further configured to control the audio output unit to output an alarm sound in response to the user motion being within a scope of a recognition limit which is predetermined to be an area inside the motion recognition scope. ### Claim 6 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the controller is further configured to change a motion speed of the object displayed by the display in response to the object moving in a predetermined area of the display according to the user motion. ### Claim 7 (depends on 6) The electronic apparatus as claimed in claim 6, wherein the controller is further configured to decrease the motion speed of the object displayed by the display at a predetermined peripheral area of the display. ### Claim 8 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the motion input unit comprises a camera photographing the user motion, wherein the motion recognition scope of the motion input unit is changed according to an angle of the camera. ### Claim 9 A method for controlling an electronic apparatus, the method comprising: displaying an object controlled by a user motion on a display; and changing a display state of the object displayed on the display in response to the user motion satisfying a predetermined spatial condition with respect to a motion recognition scope. ### Claim 10 (depends on 9) The method as claimed in claim 9, wherein the changing the display state and the object comprises changing at least one of a color, a transparency, and a shape of the object displayed on the display in response to the user motion entering into an area within a scope of recognition limit which is predetermined to be an area inside the motion recognition scope with respect to a border of the motion recognition scope. ### Claim 11 (depends on 10) The method as claimed in claim 10, wherein the changing the display state and the object comprises increasing a transparency of the object displayed on the display in response to the input user motion moving in a direction closer to a border of the motion recognition scope within the scope of a recognition limit. ### Claim 12 (depends on 9) The method as claimed in claim 9, further comprising: removing the object from being displayed on the display in response to the user motion going beyond the motion recognition scope. ### Claim 13 (depends on 9) The method as claimed in claim 9, further comprising: outputting an alarm sound in response to the user motion being input within a scope of a recognition limit which is predetermined to be an area inside the motion recognition scope. ### Claim 14 (depends on 9) The method as claimed in claim 9, further comprising: changing a motion speed of the object displayed on the display in response to the object moving in a predetermined area of the display according to the user motion. ### Claim 15 (depends on 14) The method as claimed in claim 14, wherein the changing the motion speed of the object comprising decreasing the motion speed of the object displayed on the display at a predetermined peripheral area of the display. ### Claim 16 A method of controlling an electronic apparatus, the method comprising: receiving a user motion input at the electronic apparatus, determining a spatial location of the user motion input within a motion recognition area; and configuring a display state of a pointer to be displayed by the electronic apparatus in response to the spatial location being within a predetermined area of the motion recognition area, wherein the display state is configured to adjust at least one of a color, a transparency, a shape, and a movement speed of the pointer when displayed. ### Claim 17 (depends on 16) The method of controlling an electronic apparatus of claim 16, wherein the configuring of the display state further comprises: configuring the display state such that the transparency of the pointer is increased and the movement speed of the pointer is decreased in response to the user motion having at least one of the spatial location that is near an outer border of the motion recognition area and a spatial trajectory towards the outer border. ### Claim 18 An electronic apparatus comprising: a receiver configured to receive a user motion input, and a controller configured to determine a spatial location of the user motion input within a motion recognition area, wherein the controller is further configured to adjust a display state of a pointer to be displayed by the electronic apparatus in response to the spatial location being within a predetermined area of the motion recognition area, and wherein the display state is configured to adjust at least one of a color, a transparency, a shape, and a movement speed of the pointer when displayed. ### Claim 19 (depends on 18) The electronic apparatus of claim 18, wherein the controller is further configured to adjust the display state such that the transparency of the pointer is increased and the movement speed of the pointer is decreased in response to the user motion having at least one of the spatial location that is near an outer border of the motion recognition area and a spatial trajectory towards the outer border.
