Abstract

There is provided with a management device including: a communication unit configured to receive input function information indicating input functions provided by input devices through a wireless network and receive reception level information indicating reception levels of signals which an output device connected to the wireless network has received from the input devices from the output device; and a determiner configured to determine an input device to be combined with the output device based on the input function information and the reception level information.

Claims

1. A management device comprising:

a communication unit configured to receive input function information indicating input functions provided by input devices through a wireless network and receive reception level information indicating reception levels of signals which an output device connected to the wireless network has received from the input devices from the output device; and

a determiner configured to determine an input device to be combined with the output device based on the input function information and the reception level information.

2. The device according to claim 1, wherein the communication unit receives the input function information from the input devices.

3. The device according to claim 1, further comprising a processing executor configured to receive an input signal which the input device combined with the output device transmits, and execute a processing based on the input signal to obtain processing information, wherein

the determiner transmits the processing information to the output device.

4. The device according to claim 1, wherein

the determiner determines an input device to be combined additionally with the output device, having input function different from that of the input device already combined with the output device.

5. The device according to claim 1, wherein the determiner determines to combine an input device having highest reception level out of input devices having same input function with the output device.

6. The device according to claim 1, further comprising:

an instruction signal generating unit configured to generate first instruction signals for instructing input devices which exist on the wireless network to transmit a frame for measurement with certain transmission level and a second instruction signal for instructing the output device to measure the reception levels of the frames for measurement.

7. The device according to claim 6, wherein the first instruction signals instruct the input devices to transmit the frame using a predetermined radio channel, and

the second instruction signal instructs the output device to measure the reception levels of the frames using the predetermined radio channel.

8. A device management method comprising:

receiving input function information indicating input functions provided by input devices through a wireless network;

receiving reception level information indicating reception levels of signals which an output device connected to the wireless network has received from the input devices from the output device; and

determining an input device to be combined with the output device based on the input function information and the reception level information.

9. The method according to claim 8, wherein the input function information are received from the input devices.

10. The method according to claim 8, further comprising

receiving an input signal from the input device;

executing a processing based on the input signal to obtain processing information; and

transmitting the processing information to the output device combined with the input device.

11. The method according to claim 8, further comprising

determining an input device to be combined additionally with the output device, having input function different from that of the input device already combined with the output device.

12. The method according to claim 8, wherein the determining includes determining to combine an input device having highest reception level out of input devices having same input function with the output device.

13. The method according to claim 8, further comprising:

transmitting first instruction signals for instructing input devices which exist on the wireless network to transmit a frame for measurement with certain transmission level; and

transmitting a second instruction signal for instructing the output device to measure the reception levels of the frames for measurement.

14. The method according to claim 13, wherein the first instruction signals instruct the input devices to transmit the frame using a predetermined radio channel, and

the second instruction signal instructs the output device to measure the reception levels of the frames using the predetermined radio channel.

15. An output device comprising:

a measurement unit configured to measure reception levels of signals received from input devices connected to a wireless network;

a transmission unit configured to transmit information indicating the reception levels of the input devices to a management device connected to the wireless network;

a reception unit configured to receive processing information from the management device through the wireless network, the processing information being generated based on an input signal transmitted from an input device out of the input devices to the management device; and

an output unit configured to output the processing information received by the reception unit.

16. A computer readable medium storing a computer program for causing a computer to execute instructions to perform steps of:

receiving input function information indicating input functions provided by input devices through a wireless network;

receiving reception level information indicating reception levels of signals which an output device connected to the wireless network has received from the input devices from the output device; and

determining an input device to be combined with the output device based on the input function information and the reception level information.
