Abstract

Communication between a Human Interface Device (HID) protocol capable computing device and an HID incapable remote control device is enabled by generating an operating system interface event based on a wirelessly received command from the remote control device at the BIOS of the computing device, forwarding the generated event to a control software service; determining a unique action identifier associated with the received command based on the generated event at the control software service, and forwarding one or more HID packets based on the action identifier to an HID driver such that the received command is interpreted for processing by an application on the computing device.

Claims

1. A method to be executed at least partially on a computing device for communicating with a remote control device, the method comprising:

wirelessly receiving a command generated by the remote control device;

generating an operating system interface event based on the received command at a Basic Input Output System (BIOS) of the computing device;

forwarding the generated event to a control software service;

determining a unique action identifier associated with the received command based on the received event at the control software service; and

forwarding at least one Human Interface Device (HID) packet based on the action identifier to an HID driver such that the received command is interpreted for processing by an application on the computing device.

2. The method of claim 1, wherein determining the unique action identifier includes:

querying the BIOS based on the received event at the control software service; and

receiving the unique action identifier from the BIOS.

3. The method of claim 1, wherein forwarding the at least one HID packet includes:

translating the action identifier to the at least one HID packet through an action dynamic library link (dll) module; and

sending the at least one HID packet to the HID driver.

4. The method of claim 1, further comprising:

determining if the BIOS is capable of generating the operating system interface event and the unique action identifier; and

if not

configuring the BIOS to generate operating system interface events and unique action identifiers responsive to received commands from the remote control device.

5. The method of claim 1, wherein the operating system interface is a Windows Management Instrumentation (WMI) interface.

6. A computing device capable of communicating wirelessly with a remote control device utilizing HID protocol regardless of a capability of the remote control device to generate HID compatible commands, the computing device comprising:

a wireless communication port;

a memory; and

a processor coupled to the memory, the processor configured to execute;

a BIOS capable of generating an operating system interface event based on a non-HID compatible command received through the wireless communication port, forwarding the event to a control software service, receiving a query from the control software service based on the event, and sending a unique action identifier associated with the received command to the control software service; and

the control software service capable of querying the BIOS responsive to receiving the operating system interface event, receiving the unique action identifier, translating the action identifier to at least one HID packet, and forwarding the at least one HID packet to an HID driver for processing by an application on the computing device.

7. The computing device of claim 6, wherein the control software service is further capable of:

determining whether the BIOS is capable of generating operating system interface events based on a non-HID compatible commands; and

selectively activating the wireless communication port.

8. The computing device of claim 6, wherein the control software service is further capable of:

determining whether an external transceiver capable of translating non-HID commands to HID packets is present; and

automatically activating operating system interface event generation and action identifier transmission operations if the external transceiver is not present.

9. The computing device of claim 6, wherein a first portion of received commands are non-HID compatible commands and a second portion of received commands are HID compatible commands, and wherein the BIOS and the control software service are configured such that the first portion of received commands are processed through generation of operating system interface events and translation into HID packets using unique action identifiers, and the second portion of the received commands are forwarded directly to the HID driver.

10. The computing device of claim 6, wherein the computing device and the remote control device communicate through one of the following:

an infrared communication and a short range Radio Frequency (RF) communication.

11. A system for enabling short range communication utilizing HID packets, the system comprising:

a remote control device including a plurality of input elements, wherein at least a portion of the elements is configured to generate a non-HID compliant device command; and

a host computing device including;

a modified BIOS configured to;

receive a command from the remote control device through a wireless communication port;

if the command is HID-compatible, forward to an HID driver;

else, generate and forward an operating system interface event to a control software service; and

send a unique action identifier associated with the received command to the control software service responsive to a query from the control software service; and

the control software service configured to;

query the BIOS responsive to receiving the operating system interface event;

translate the action identifier to at least one HID packet based on the unique action identifier using an action dll; and

forward the at least one HID packet to the HID driver for processing by an application on the computing device.

12. The system of claim 11, wherein the control software service is further configured to:

determine whether an external transceiver capable of translating non-HID commands to HID packets is present; and

if the transceiver is present, activate an automatic filtering mechanism capable of intercepting HID commands from the external transceiver and enable performance of an ancillary function associated with the intercepted HID command.

13. The system of claim 12, wherein the ancillary command includes one of:

launching an application associated with the intercepted command and adjusting a host computing device user interface parameter associated with the intercepted command.

14. The system of claim 11, wherein the control software service includes a first module for querying and receiving action identifiers from the BIOS and a second module for accessing the operating system interface.

15. The system of claim 11, wherein the action identifier is a numeric value unique to each distinct command from the remote control device agreed between the BIOS and the control software service.
