Abstract

A unified user input device is provided. The input device may include keys normally provided as part of a general purpose alphanumeric computer keyboard. In addition, a positional controller is provided. Both the conventional alphanumeric keys and the positional controller are associated with the same device platform. Additionally, special function keys may also be provided in association with the positional controller. Signals encoding the selection of an alphanumeric key, a control input, or a special function key are communicated to an interconnected computer using a common, conventional keyboard connection, and a common signaling protocol.

Claims

1. A system for controlling operation of a multiple component system, comprising:

a device platform;

an alphanumeric keyboard including a first plurality of keys incorporated in said device platform, wherein selection of a key included in said first plurality of keys provides a signal encoding a printable character in accordance with a first signaling protocol;

a positional controller incorporated in said device platform, wherein said positional controller provides a first output signal;

a first processor, wherein said first output signal provided by said positional controller is translated into at least a first non-printable character in accordance with said first signaling protocol; and

a communication channel interconnected to said device platform, wherein said signal encoding a printable character in accordance with a first signaling protocol and said signal encoding at least a first non-printable character in accordance with said first signaling protocol are both carried by said communication channel to a receiving device.

2. The system of claim 1, wherein said first processor additionally provides said signal encoding a printable character in accordance with said first signaling protocol in response to said selection of a key included in said first plurality of keys.

3. The system of claim 1, further comprising:

a positional controller encoder, wherein said encoder translates a position of said positional controller into said first output signal.

4. The system of claim 1, further comprising:

a second processor, wherein said second processor operates to provide said signal encoding a printable character in accordance with said first signaling protocol to said communication channel.

5. The system of claim 1, wherein said positional controller comprises at least one of a joystick, a touch pad, a mouse, a trackball, and a button.

6. The system of claim 1, wherein said positional controller includes a joystick, said joystick extending from a surface of said device platform, wherein an end of said joystick is at least one inch from said surface of said device platform.

7. The system of claim 6, wherein said positional controller additionally includes a plurality of input buttons.

8. The system of claim 7, wherein selection of a button included in said plurality of input buttons provides a signal encoding a non-printable character in accordance with said first signaling protocol.

9. The system of claim 1, wherein said receiving device comprises a personal computer.

10. The system of claim 9, wherein said personal computer is running application software comprising an integrated video surveillance subsystem.

11. The system of claim 9, wherein said personal computer is running application software comprising video surveillance camera control software.

12. The system of claim 1, wherein said operation of said positional controller comprises moving a joystick provided by said position controller, wherein said moving a joystick produces said first output signal, wherein said first control signal is translated to said at least a first non-printable character.

13. The device of claim 1, wherein said communication channel comprises one of a PS/2 and a USB cable.

14. The system of claim 1, wherein said first signaling protocol includes ASCII encoding.

15. The system of claim 1, wherein said device platform includes a first area defined by a first perimeter, and wherein said alphanumeric keyboard and said positional controller are located within said first area.

16. A method for controlling components of a surveillance system, comprising:

receiving from a user input device a selection of an alphanumeric character;

producing a signal encoding said selected alphanumeric character as a printable character according to a first communication protocol;

receiving from said user input device a control input from a positional controller associated with said user input device;

producing a signal encoding said received control input as a non-printable character according to said first communication protocol; and

wherein said user input device includes an integrated device platform having a plurality of alphanumeric keys for selecting the alphanumeric character and a positional controller for creating the control input.

17. The method of claim 16, wherein said producing a signal encoding said received control input includes:

encoding at least a first aspect of said control input;

converting said encoded at least a first aspect of said control input a non-printable character according to said first communication protocol.

18. The method of claim 17, wherein said at least a first aspect of said control input includes one of a stroke amplitude and an stroke direction.

19. The method of claim 17, wherein said encoding at least a first aspect of said control input is performed by a first processor and wherein said producing a signal encoding said selected alphanumeric character is performed by a second processor.

20. The method of claim 16, wherein said producing a signal encoding said selected alphanumeric character as a printable character according to a first communication protocol comprises producing a signal encoding said selected alphanumeric character using an ASCII code corresponding to said printable character.

21. The method of claim 16, wherein said producing a signal encoding said received control input as a non-printable character according to said first communication protocol comprises producing a signal encoding said control input using an ASCII code corresponding to a non-printable character.

22. An integrated keyboard device, comprising:

means for receiving selected alphanumeric inputs associated with a first keyboard platform;

means for first encoding said selected alphanumeric inputs;

means for outputting said first encoded selected alphanumeric inputs;

means for receiving selected positional control inputs associated with said first keyboard platform;

means for second encoding said selected positional control inputs;

means for outputting said second encoded selected positional control inputs;

means for directing said first encoded inputs to a first application; and

means for directing said second encoded inputs to a second application.

23. A system for controlling operation of a multiple component system, comprising:

a device platform;

an alphanumeric keyboard incorporated in said device platform, said alphanumeric keyboard including alphanumeric keys for each letter of the alphabet (A-Z), a plurality of function keys designated as at least keys F1-F10, a plurality of numeric keys designated as keys 1-9;

a positional controller incorporated in said device platform and spaced from said plurality of alphabetical, numeric, and function keys, said positional controller being in the form of a joystick, said joystick for controlling one or more cameras within said system, said joystick extending above said device platform enabling a user to grip said joystick with the palm of a user'"'"'s hand;

a plurality of camera control keys for controlling various camera functions including at least a plurality of camera control keys for controlling focus and zoom of said camera;

said alphabetical keys and said numeric keys providing a signal encoding for production of printable characters in accordance with a first signaling protocol;

said positional controller providing another output signal;

a first processor incorporated within said device platform, wherein said another output signal provided by said positional controller is translated into at least a first non-printable character in accordance with said first signaling protocol;
