An information processing apparatus, an information processing method and a computer-readable medium for use with a virtual reality environment are provided. The information processing apparatus includes a sensing-area setting means for setting an area used to sense information on objects, and a transmission-area setting means for setting an area used for transmitting information on an object. The transmission area may be set wider than the sensing area. Thus, according to the present invention, information on an object can be reported to another object located at a remote position with a higher degree of reliability.
