Client device

An information processing method performed by an information processing apparatus, the method comprising:

• capturing a subject and outputting image data corresponding to the captured subject;
• displaying the captured image;
• detecting whether an image preset as a marker image exists in the image data;
• constructing, when the marker image is detected in the image data, a real-world coordinate system computed from a position and orientation of the marker image;
• computing information corresponding to the information processing apparatus's position and orientation in the constructed real-world coordinate system;
• acquiring at least one of data stored in a storage unit of the information processing apparatus, data existing on a network, and data transmitted from another information processing apparatus;
• placing the acquired data in the constructed real-world coordinate system;
• displaying the acquired data as one or more virtual objects at on-screen positions of a display corresponding to positions where the acquired data was placed;
• and
• transmitting information corresponding to a position and orientation of the information processing apparatus in the constructed real-world coordinate system to the another information processing apparatus.

A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to perform a process comprising:

• capturing a subject and outputting image data corresponding to the captured subject;
• displaying the captured image;
• detecting whether an image preset as a marker image exists in the image data;
• constructing, when the marker image is detected in the image data, a real-world coordinate system computed from a position and orientation of the marker image;
• computing information corresponding to the information processing apparatus's position and orientation in the constructed real-world coordinate system;
• acquiring at least one of data stored in a storage unit of the information processing apparatus, data existing on a network, and data transmitted from another information processing apparatus;
• placing the acquired data in the constructed real-world coordinate system;
• displaying the acquired data as one or more virtual objects at on-screen positions of a display corresponding to positions where the acquired data was placed;
• and
• transmitting information corresponding to a position and orientation of the information processing apparatus in the constructed real-world coordinate system to the another information processing apparatus.
