Abstract

An input device is configured to act as a remote trackpad for an output device. The input device includes a touchscreen configured to display an image and receive either a single-touch or multi-touch user input. A communication interface configured to support wired or wireless communication links with an output device and send the user input to the output device.

Claims

1. An input device, comprising:

a touchscreen configured to display an image and receive single-touch and multi-touch user input; and

a communication interface configured to support wired and wireless communication links with an external device and send the user input to the external device.

2. The input device of claim 1, wherein the touchscreen receives user input by using at least one of a heat sensor, a pressure sensor, a high capture rate camera, an infrared light sensor, an optical sensor, a ultrasonic receivers, a tuned electromagnetic induction, a transducer microphone, a laser rangefinder, and a shadow capture.

3. The input device of claim 1, wherein the input device is configured to slide into the external device and be directly coupled to the external device through the communication interface.

4. The input device of claim 1, wherein the wired communication supported by the communication interface comprises a universal serial bus (USB).

5. The input device of claim 1, wherein the wireless communication supported by the communication interface comprises at least one of Bluetooth, Wireless Fidelity (Wi-Fi), and visible light communication (VLC).

6. The input device of claim 1, wherein the input device comprises at least one of a mobile station and a personal digital assistant (PDA).

7. The input device of claim 1, wherein the communication interface is further configured to support bi-directional communication with the external device, and wherein the touchscreen displays images based on data received from the external device.

8. The input device of claim 1, wherein the external device comprises at least one of a television, an external display, a laptop computer, and a desktop computer.

9. The input device of claim 1, wherein the external device is a second input device that comprises:

a second touchscreen configured to display an image and receive single-touch and multi-touch user input; and

a second communication interface configured to support wired and wireless communication links with an output device and send the user input to the output device.

10. The input device of claim 1, wherein the communication interface is further configured to support bi-directional communication with a second input device.

11. A mobile device, comprising:

a display screen comprising touchscreen configured to display an image and receive single-touch and multi-touch user input;

a transceiver configured to transmit the user input to an external device over a wireless communication link;

a communication port configured to send the user input to the external device over a wired communication link.

12. The mobile device of claim 11, wherein the touchscreen comprises optical sensors between pixels, the optical sensors configured to sense objects placed on a surface of the touchscreen while the touchscreen displays an image.

13. The mobile device of claim 11 wherein the mobile device is configured to slide into a slot of the external device and be directly coupled to the external device through the communication port.

14. The mobile device of claim 11, wherein the wired communication supported by the communication interface comprises a universal serial bus (USB), and wherein the wireless communication supported by the communication interface comprises at least one of Bluetooth, Wireless Fidelity (Wi-Fi), and visible light communication (VLC).

15. The mobile device of claim 11, wherein the external device is a laptop computer.

16. The mobile device of claim 11, wherein the external device is a television, and the user input corresponds to controls for a menu screen on the television.

17. The mobile device of claim 11, wherein the transceiver and the communication port are further configured to support bi-directional communication with the external device, and wherein the touchscreen displays images based on data received from the external device.

18. The mobile device of claim 11, wherein the transceiver and the communication port are further configured to support bi-directional communication with a second mobile device.

19. The mobile device of claim 18, wherein the second mobile device is configured to slide into a slot of the external device and be directly coupled to the external device through the communication port.

20. The mobile device of claim 19, wherein the mobile device is configured to communicate directly with the external device and the second mobile device.
