Abstract

An interface is provided that corresponds to an individual person without being restricted to a particular place within a room, by performing gesture recognition while identifying an individual person. A stereo camera (1) picks up an image of a user (4), and based on the image pickup output, an image processor 2 transmits a color image within a visual field and a distance image to an information integrated recognition device (3). The information integrated recognition device (3) identifies an individual by the face of the user (4), senses the position, and recognizes a significant gesture based on a hand sign of the user (4). The information integrated recognition device (3) executes a command corresponding the identified user (4) and performs operations of all devices (6) to be operated in the room (such as a TV set, an air conditioner, an electric fan, illumination, acoustic condition, and window opening/closing).

Claims

1. An interface apparatus, comprising:

an image processor configured to pick up an image of a room in an indoor space by a plurality of stereo cameras, and to produce a picked up image within a visual field and a distance image based on an indoor coordinate system for each of the stereo cameras;

a registration section configured to register an indoor object device and a position of the indoor object device in the indoor space;

an object recognition section configured to extract recognition objects from the picked up image based on distance information from each of the stereo cameras, and to classify the extracted recognition objects, corresponding to a person, into a head portion and a hand sign pointed by the person in the indoor space;

a personal identification section configured to identify the person based on the recognition result of the head portion and a stature of the person; and

a hand sign identification section configured to issue a command for an indoor operation to operate the indoor object device corresponding to an object to be operated, based on a direction of the hand sign pointed by the person, a kind and movement of the hand sign, and the identity of the person identified by the personal identification section;

a personal state monitoring section configured to acquire and store logs of all behavior of the person in the indoor space, wherein

the personal state monitoring section is configured to previously register the behavior to be monitored for each individual person, in a personal behavior log database,

the object recognition section is configured to note an object sequentially from the top side thereof along the height direction of the indoor space, and to recognize the object by clipping the object sequentially from the top side thereof, and

the hand sign identification section is configured to utilize the personal behavior logs, corresponding to the registered behavior to be monitored for each individual person, for identification of the hand sign.

2. The interface apparatus according to claim 1, wherein the hand sign identification section is configured to issue commands for an indoor operation to operate the indoor object device corresponding to the object to be operated each based on the hand sign, the command corresponding to the hand sign varying from a previously registered individual person to another.

3. The interface apparatus according to claim 1, further comprising:

the personal state monitoring section further configured to observe postures of an individual person over a period of time while identifying the person, and to provide notification of the observation results by voice or on a display; and

an operation data registration section configured to register the behavior, to be observed, of the person.

4. The interface apparatus according to claim 1, wherein the hand sign identification section is further configured to issue the command for the indoor operation to operate the indoor object device corresponding to an object to be operated based on whether the person is permitted to issue the command.
