    • A method for detecting direction when interfacing with a computer program is provided. The method includes capturing an image presented in front of an image capture device. The image capture device has a capture location in a coordinate space. When a person is captured in the image, the method includes identifying a human head in the image and assigning the human head a head location in the coordinate space. The method also includes identifying an object held by the person in the image and assigning the object an object location in coordinate space. The method further includes identifying a relative position in coordinate space between the head location and the object location when viewed from the capture location. The relative position defines a pointing direction of the object when viewed by the image capture device. The method may be practiced on a computer system, such as one used in the gaming field.
    • 提供了一种用于在与计算机程序接口时检测方向的方法。 该方法包括捕获呈现在图像捕获装置前面的图像。 图像捕获设备在坐标空间中具有捕获位置。 当人物被捕获在图像中时,该方法包括识别图像中的人类头部并将人物头部分配给坐标空间中的头部位置。 该方法还包括识别由人在图像中保持的对象,并将对象位置分配给坐标空间。 该方法还包括当从捕获位置观看时识别头部位置和对象位置之间的坐标空间中的相对位置。 相对位置定义了由图像捕获装置观察时对象的指向方向。 该方法可以在诸如在游戏领域中使用的计算机系统的计算机系统上实现。
