Abstract

A device for remotely controlling a computer system operable in a graphic user interface environment. The remote control device comprises a micro-computer for converting a remote control signal transmitted from a remote control transmitter into a combined key signal and controlling the operation of the computer system in response to input data and command, a device driver for instructing an operation based on the combined key signal from the micro-computer and applying data and a command to the micro-computer if the combined key signal indicates the operation of the micro-computer, and a user interface software for performing bidirectional communication with the device driver and driving an application software corresponding to the combined key signal from the micro-computer to perform the operation based on the combined key signal. According to the present invention, a remote control function can always be stably performed, and can cope flexibly with variations in hardware and software environments. Further, the user can freely select a key signal combination to prevent a conflict with an application software.

Claims

a micro-computer for converting a remote control signal into a combined key signal and controlling operation of said computer system in response to input data and command;

a device driver for instructing an operation based on the combined key signal from said micro-computer and applying data and command to said micro-computer, when the combined key signal indicates the operation of said micro-computer; and

a user interface software for performing bidirectional communication with said device driver and driving an application software corresponding to the combined key signal from said micro-computer to perform the operation based on the combined key signal.

2. The device of claim 1, further comprised of said device driver operating in a privileged mode to perform bidirectional communication with the micro-computer for instructing said operation based on the combined key signal.

3. The device of claim 1, further comprised of said user interface software having a remote control extension function of changing combined keys according to a user'"'"'s selection and a remote control change function of replacing a specific application software with a different application software.

4. A method for remotely controlling a computer system operable in a graphic user interface environment, comprising the steps of:

discriminating a combined key signal on the basis of a remote control signal and informing an input of the combined key signal;

checking a function of the combined key signal;

transmitting data and a command to a micro-computer, when the function of the combined key signal is associated with an operation of said micro-computer;

informing a user interface software of the function of the combined key signal, when the function of the combined key signal is not associated with the operation of said micro-computer; and

detecting an application software corresponding to the function of the combined key signal from previously registered data and driving the detected application software.

5. The method of claim 4, further comprised of generating an interrupt to inform the put of the combined key signal in response to receipt of the remote control signal.

6. The method of claim 4, further comprised of determining the input of the remote control signal at an interval of predetermined time to inform the input of the combined key signal.

7. A device for remotely controlling a computer system operable in a graphic user interface environment, comprising:

a remote control transmitter having a plurality of discrete keys that are independently operable by manual depression to produce a remote control signal representing different remote control functions; and
