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.

A radio-frequency device includes a PAA processing portion configured to control a directivity of reception of a receiver antenna device, a received-signal-strength detecting portion configured to detect a strength of the received signal received by the receiver antenna device, and a direction detecting portion configured to detect the direction toward the communication object, on the basis of a direction in which a higher one of two strength values of the received signal respectively detected in first and second maximum-reception-directivity directions of a predetermined angular difference established by the PAA processing portion is minimal. The direction detecting portion is operated based on a fact that the received signal strength is minimal at the bottom of a gain existing in an area of overlapping of two main lobes extending in the respective two directivity directions of the predetermined angular difference, so that the resolution of detection can be made higher than in the case based on the main lobe direction in which the sensitivity of communication with the radio-frequency tag is maximum. Accordingly, the direction toward the radio-frequency tag can be suitably detected.
