Abstract

A doorphone is provided with a camera, a microphone, a button serving as an input device, and a loudspeaker serving as an output device. When a visitor pushes the button, the camera starts recording an image and the microphone becomes ready for input of voice. The doorphone sends the recorded image and the input voice to an operation panel. The doorphone sends the recorded image and the input voice to the home server as well. Upon reception of the image and the voice, the home server recognizes which sensor senses a user through the use of a LAN, and selects a video/audio device (e.g., a personal computer) associated with that sensor as a data destination device. The image and voice received from the doorphone are transferred to the selected video/audio device through the LAN.

Claims

1. A network system, having human sensors, which transfers data from a first device to second devices by way of a server device,

the server device comprising:

a positional information storage unit which stores positional information representing correspondence between the human sensors and the second devices;

a transfer destination selecting unit configured to select one of the second devices as a destination device to which the data transmitted from the first device should be sent, based on sensing information from the human sensors and the positional information stored in the positional information storage unit; and

a data transfer unit configured to transfer data from the first device to the one of the second devices which is selected by the transfer designation selecting unit.

2. The network system according to claim 1, wherein the first device is a doorphone having a camera and a microphone, and data on an image photographed by the camera and data on voice entered from the microphone are transmitted to the server device.

3. The network system according to claim 1, wherein the human sensors are installed in different rooms respectively.

4. The network system according to claim 1, wherein, when a plurality of human sensors sense humans, the transfer destination selecting unit of the server device selects all of the second devices which the positional information associates with the plurality of human sensors as destination devices to which the data transmitted from the first device should be sent.

5. The network system according to claim 1, wherein the second devices comprising an environment setting unit configured to determine whether or not a power supply should be automatically turned on, when the data transmitted by the first device is received from the server device.

6. The network system according to claim 1, wherein the second devices comprising:

a display device; and

an image superimposing unit configured to superpose image data, which is transmitted by the first device and transferred by the server device, on image data shown on the display device.

7. The network system according to claim 6, wherein the second devices further comprising an environment setting unit configured to determine whether or not the image data transmitted by the first device should be superposed on the image data shown on the display device when the image data transmitted by the first device is transferred by the server device.

8. The network system according to claim 1, wherein:

the first device comprising a designating unit configured to designate a data recipient;

the human sensors comprising a identifying unit configured to identify a person; and

the transfer destination selecting unit of the server device selects one of the second devices which the positional information associates with a human sensor that senses a data recipient designated by the designating unit of the first device, as a destination device to which the data transmitted from the first device should be sent.

9. The network system according to claim 1, wherein:

the first device is a videophone that performs communications through the network by use of images;

the human sensors comprising a identifying unit configured to identify a sensed person;

the server device comprising a user information storage unit which stores user information indicating a communication device used by the person identifiable by the human sensors; and

the data transfer unit of the server device transfers image data transmitted from the first device to the second device selected by the transfer destination selecting unit of the server device, transfers voice data transmitted from the first device to a communication device indicated by the user information storage unit as a device using the person identified by the human sensor, and transfers the voice data transmitted from the communication device to the first device.

10. A server device which transfers data from a first device to second devices, comprising:

a user position determining unit configured to acquire sensing information on human sensors;

a positional information storage unit which stores positional information representing correspondence between the human sensors and the second devices;

a transfer destination selecting unit configured to select one of the second devices as a destination device to which the data transmitted from the first device should be sent, based on the sensing information acquired by the user position determining unit and the positional information stored in the positional information storage unit; and

a data transfer unit configured to transfer data from the first device to the one of the second devices selected by the transfer destination selecting unit.

11. The server device according to claim 10, wherein, when a plurality of human sensors sense humans, the transfer destination selecting unit selects all of the second devices which the positional information associates with the plurality of sensors as destination devices to which the data transmitted from the first device should be sent.

12. The server device according to claim 10, wherein the transfer destination selecting unit selects one of the second devices which the positional information associates with a human sensor that senses a data recipient designates by the first device, as a destination device to which the data transmitted from the first device should be sent.

13. The server device according to claim 10, further comprising a user information storage unit which stores user information indicating a communication device used by a person identifiable by the human sensors;

wherein the data transfer unit transfers image data transmitted from the first device to the second device selected by the transfer destination selecting unit, transfers voice data transmitted from the first device to a communication device indicated by the user information storage unit as a device using the person identified by the human sensor, and transfers the voice data transmitted from the communication device to the first device.

14. A communication method for transferring data from a first device to second devices, comprising:

acquiring sensing information on human sensors;

selecting one of the second devices as a destination device to which the data transmitted from the first device should be sent, based on the sensing information and positional information representing correspondence between the human sensors and the second devices; and

transferring data from the first device to the one of the selected second devices.

15. The communication method according to claim 14, wherein, when a plurality of human sensors sense humans, the selecting one of the second devices selects all of the second devices which the positional information associates with the plurality of human sensors, as destination devices to which the data transmitted from the first device should be sent.

16. The communication method according to claim 14, wherein the selecting one of the second devices selects one of the second devices which the positional information associates with a human sensor that senses a data recipient designated by the first device, as a destination device to which the data transmitted from the first device should be sent.
