In some exemplary embodiments, the touch screen is used as a backup remote to a display and can be used as a 3D pointing device. The touch screen can be an overlay on display surface to control the display. Alternatively, the touch screen can be retractable and ejectable from the display housing. In addition, the touch screen can be wearable. Further, the touch screen can function to control one or more devices, e.g., television, set-top box, DVR, gaming consoles. ## Claims ### Claim 1 A mobile device configured to control a separate display, comprising: a transmit/receive unit; a touch screen display; and a processor, in communication with the transmit/receive unit and the touch screen display, and configured to perform remote control functions associated with the separate display, wherein: the touch screen display is configured to display a control object associated with control of the contents displayed on the separate display, and the processor is configured to: determine a three-dimensional (3D) movement of the mobile device; select between (1) a first mode of operation in which a movement of a cursor on the separate screen is controlled based on the 3D movement of the mobile device; and (2) a second mode of operation in which the movement of the cursor is controlled using the touch screen display of the mobile device, detect a movement across the touch screen display; and determine, in accordance with the selected second mode of operation, movement information associated with the cursor displayed on the separate display based on the detected movement across the touch screen display after compensation for 3D movement of the touch screen display using the determined 3D movement of the mobile device; and the transmit/receive unit is configured to send the determined movement information. ### Claim 2 (depends on 1) The mobile device of claim 1, wherein the mobile device is configured to operate as a 3D pointing device. ### Claim 3 (depends on 2) The mobile device of claim 2, wherein when the touch screen display operates as the 3D pointing device, a user can point to a portion of the separate display and tap the touch screen display to select a desired item or a desired function. ### Claim 4 (depends on 1) The mobile device of claim 1, wherein the touch screen display is backlit to display any of: a numeric keypad display, an enter button, a last button, or a scroll bar for controlling volume, as the control object. ### Claim 5 (depends on 1) The mobile device of claim 1, wherein the touch screen display is configured to receive user input on a surface of the touch screen display such that the movement of the cursor on the separate display tracks a compensated motion of the user input on the surface of the touch screen display, the compensated motion being based on the detected movement across the touch screen display and the 3D movement of the touch screen display. ### Claim 6 (depends on 1) The mobile device of claim 1, wherein the touch screen display is a separate device from the separate display and is activated by tapping a surface of the touch screen display. ### Claim 7 (depends on 1) The mobile device of claim 1, wherein the touch screen is activated via a voice command. ### Claim 8 (depends on 1) The mobile device of claim 1, wherein the touch screen display provides any of: (1) channel entry; (2) channel control; (3) volume control; (4) power control; (5) cursor control; (6) scrolling; or (7) zooming control. ### Claim 9 A method of controlling a separate display from a mobile device, the method comprising: configuring a processor to perform remote control functions associated with the separate display; displaying, by a touch screen display, a control object associated with control of the contents displayed on the separate display; determining a three-dimensional (3D) movement of the mobile device; selecting, by the processor, between (1) a first mode of operation in which a movement of a cursor on the separation screen is controlled based on the 3D movement of the mobile device; and (2) a second mode of operation in which the movement of the cursor is controlled using the touch screen display of the mobile device; detecting a movement across the touch screen display; determining, by the processor in accordance with the selected second mode of operation, movement information associated with the cursor displayed on the separate display based on the detected movement across the touch screen display after compensating for 3D movement of the touch screen display using the determined 3D movement of the mobile device; and sending, by a transmit/receiver unit, the determined movement information. ### Claim 10 (depends on 9) The method of claim 9, further comprising operating the mobile device as a 3D pointing device. ### Claim 11 (depends on 10) The method of claim 10, wherein when the touch screen display operates as the 3D pointing device, selecting a desired item or a desired function displayed on the separate display by pointing the mobile device to a portion of the separate display representing the desired item or the desired function and tapping the touch screen display. ### Claim 12 (depends on 9) The method of claim 9, further comprising displaying, by the touch screen display, any of: a numeric keypad display, an enter button, a last button, or a scroll bar for controlling volume, as the control object. ### Claim 13 (depends on 9) The method of claim 9, further comprising receiving, by the touch screen display, user input on a surface of the touch screen display such that the movement of the cursor on the separate display tracks a compensated motion of the user input on the surface of the touch screen display, the compensated motion being based on the detected movement across the touch screen display and the 3D movement of the touch screen display. ### Claim 14 (depends on 9) The method of claim 9, further comprising tapping a surface of the touch screen display to activate the mobile device. ### Claim 15 (depends on 9) The method of claim 9, further comprising activating the mobile device via a voice command. ### Claim 16 (depends on 9) The method of claim 9, further comprising providing, via the touch screen display, functions for any of: channel entry; channel control; volume control; power control; cursor control; scrolling; or zooming control. ### Claim 17 (depends on 1) The mobile device of claim 1, further comprising a sensor unit configured to sense acceleration of the touch screen display, wherein the processor is configured to determine a tilt movement of the touch screen display and to compensate for the tilt movement of the touch screen display in the second mode of operation. ### Claim 18 (depends on 1) The method of claim 1, further comprising: sensing an acceleration of the touch screen display; determining a tilt movement of the touch screen display; and compensating for the tilt movement of the touch screen display in the second mode of operation.
