2. Description of the Related Art Conventionally, when a system that responds to a remote control is developed, for example, a communication device driver conforming to an infrared communication protocol (IrDA) must be developed on a receiving device. We were developing according to the protocol. Conventionally, it has also been necessary to incorporate measures to prevent chattering of input codes (a phenomenon in which the same input code is fetched in a certain period of time due to noise or the like) in the communication device driver.

More specifically, when developing a device for converting an infrared input into an electric signal, the waveform often fluctuates and noise is often generated, and a certain timing delay is always required to take a plurality of the same signals. It was necessary to create a mechanism that did not require it.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of an input conversion device according to an embodiment of the present invention. The input device 2 is connected to the input device 1. And the signal and conversion type from the input device 1
(Speech / key code / mouse code) is received by the input conversion device 2.

The input conversion device 2 is composed of a plurality of microcomputer chips, and the contents of the input conversion device 2 will be described in more detail. First, the setting file 3 describing what code is to be converted is stored in the input device 1.
At the beginning of receiving a signal from a mouse event conversion part 4, a keyboard conversion part 5, a speech recognition analysis conversion part 6, and another code conversion part 7.
Are divided into Each conversion section has a chattering prevention section 8 as a filter.

An output signal from the input device 2 is communicated to the external target device 9. Then, the external target device device 9 reads the input code on its own device side, analyzes what code has been converted, and performs processing according to the code, thereby completing the communication between the two devices.

Next, the hardware blocks of the voice recognition chip and the voice recognition SW (switch) will be described with reference to FIG. In FIG. 2, a voice signal is transferred to a voice recognition command conversion block portion 11 by pressing a voice recognition SW portion 10. Next, the voice recognition command conversion block section 11 analyzes the voice signal sent and converts it into a waveform (signal) including chattering.

Thereafter, Ir is input to the input conversion block 12 and
After being converted into a DA signal, the signal is notified to the navigation device through the IrDA data transmission block 13.

In the navigation apparatus-side block, IrDA data is received by the IrDA data acquisition block 14 and transmitted to the input conversion block 15 as it is. Then, the data acquisition block 16 acquires the data by converting it in accordance with the given conversion model (keyboard, mouse, katakana code capable of recognizing voice).

Next, the processing on the data receiving side will be described with reference to the flowchart of FIG. First, in step S1, when data is received, the data type (type) is first 1by
This is determined because it is stored in te. That is,
As shown in FIG. 3, a waveform data signal is received and converted into an 8-bit system. In FIG. 3, it is converted to "11011101", that is, bbh (187), but the data type (type) is determined based on the first byte. By default, 1 is stored to convert to a key code, but when a key on the remote control is pressed, 2 is stored in the voice recognition SW.
When (switch) is pressed, code 3 is the data type
The (type) is notified to the partner device (input conversion device).

When the data type (type) is 1 or 2, the data is converted at regular intervals as data. When the data type (type) is 3, the first byte is followed by the actual data from the second byte onward with the total number of data bytes (see FIG. 4).

Next, in step S2, it is determined whether it is a keyboard code, a mouse code, or a voice code, and the process branches.

If it is determined that the input code is a keyboard code, the corresponding code setting file is read in step S3.

In step S4, the input data is converted into a keyboard code with reference to the remote controller key and keyboard corresponding code setting file (see FIG. 5) read in step S3, and processing (keyboard corresponding processing) is performed. .

If it is determined in step S2 that the code is not a keyboard code, then in step S5 it is determined whether the code is a mouse code or a voice code, and the process branches.
If it is a mouse code, a setting code file that describes which key on the remote control should be converted to which code on the mouse when the mouse code is pressed in the mouse code handling process (see FIG. 6)
Is read.

In step S6, a mouse code handling process is performed. Further, in step S7, three types of messages of mouse movement, mouse click, and mouse double click are handled. (If there are such types, even if the input conversion device of the present invention is applied to the Internet browser screen, sufficient access can be achieved.)

On the other hand, if it is determined in step S5 that the input code is a voice code, a voice code conversion process is performed in step S8. Here, the format of the audio code is shown in FIG. In FIG. 7, the input conversion code of the first byte is “3”, the total data length of the second byte is “6”,
The actual data at the third byte is the content “Tokyo”. Then, this is converted from the transmitted voice waveform code into a half-width katakana code and the signal is transmitted. Finally, in step S9, an operation of returning to step S1 is performed again.

[0029]

As described above, according to the present invention, remote communication between remotely connected devices irrespective of wired / wireless can be handled by input codes which can be easily interpreted by each other. Although only the navigation device-specific one has been described here, the processing for the remote control keys in the navigation device may be left to the keyboard driver and only the coding for the corresponding key may be performed as an application.

Further, since it can be converted into a mouse code, it is possible to refer to and select an Internet browser on a navigation device.

If the input waveform can be interpreted,
Since remote communication other than IrDA is also possible, various forms of remote communication are possible.
