INTERFACE APPARATUS, GESTURE RECOGNITION METHOD, AND GESTURE RECOGNITION PROGRAM
First Claim
1. An interface apparatus configured to output an operation signal to a target apparatus operated in accordance with a gesture command, the interface apparatus comprising:
- a reference object detection unit configured to detect a reference object having a feature similar to a predetermined reference feature value from an image taken by an image pickup unit and generate reference information identifying the reference object;
an operating object identifying unit configured to, based on the reference information, identify as the operating object a feature object included in the image and satisfying a predetermined identification condition in terms of a relative relationship with the reference object and extract operating object information identifying the operating object; and
an operation signal generation unit configured to start detecting the gesture command according to a change in position of the identified operating object and generate the operation signal corresponding to the gesture command.

Abstract
An interface apparatus is configured to output an operation signal to a target apparatus operated in accordance with a gesture command. In the interface apparatus, a reference object detection unit detects a reference object having a feature similar to a predetermined reference feature value from an image captured by an image capture unit and generates reference information identifying the reference object. Based on the reference information, an operating object identifying unit identifies as the operating object a feature object included in the image and satisfying a predetermined identification condition in terms of a relative relationship with the reference object and extracts operating object information identifying the operating object. An operation signal generation unit starts detecting the gesture command according to a change in position of the identified operating object and generates the operation signal corresponding to the gesture command.

12. A gesture recognition method in an interface apparatus configured to output an operation signal to a target apparatus operated in accordance with a gesture command, the method comprising:
-
detecting a reference object having a feature similar to a predetermined reference feature value from an image taken by an image pickup unit and generating reference information identifying the reference object; based on the image and the reference information, identifying a feature object satisfying a predetermined identification condition in terms of a relative relationship with the reference object as an operating object; extracting operating object information identifying the operating object; starting detecting the gesture command based on a change in position of the identified operating object; and generating the operation signal according to the gesture command.

13. A computer readable medium storing a gesture recognition program executable by an operation circuit configured to generate an operation signal to give an operation command to a target apparatus operated in accordance with a gesture command recognized based on an image taken by an image pickup unit, the program causing the operation circuit to execute a process comprising:
-
detecting a reference object having a feature similar to a predetermined reference feature value from the image captured by the image capture unit and generating reference information identifying the reference object; based on the image and the reference information, identifying a feature object satisfying a predetermined identification condition in terms of a relative relationship with the reference object as an operating object; extracting operating object information identifying the operating object; and detecting the gesture command based on a change in position of the identified operating object, the program causing the operation circuit to output the operation signal according to the gesture command.
