BRIEF SUMMARY
DESCRIPTION

Sound Producing Method and Sound Producing Apparatus


TECHNICAL FIELD

This invention relates to a sound producing method and a sound producing apparatus for setting virtual sound space corresponding to virtually actualized (virtual realistic) space displayed on display means.


BACKGROUND ART

In recent years, there are being put into practical use on line network service systems in which client computers and server computers are connected through communication lines, and user accepts offer of various information from the server computers, or receives service such as video viewing/listening or ordering of goods, etc on the corresponding client computer.
Moreover, in recent years, in the above-mentioned network service system, it has been popularized to beautifully represent the service contents, or to carry out presentation of the concept model (concretely represented picture of abstract data) or metaphor (picture copying actual article) by using, e.g., three-dimensional graphics on the display of the monitor device connected to the client computer to thereby carry out display which is three-dimensional and is close to the actual (realistic) world (i.e., display of the virtually actualized space) to represent the service contents for user.
Meanwhile, in the case of displaying the virtually actualized space on the display of the monitor unit as described above, display by the graphical representation is generally carried out.
However, information that human being acquires (obtains) within the actual world are not limited to visual (sense) information obtained from the eyes, but also include auditory (sense) information obtained from the ears also occupies considerable ratio thereof. On the contrary, within the above-described general virtually actualized space, since only feedback sound with respect to the operation and BGM (Background Music) irrelevant to the content of the virtually actualized space are mainly supported as the elements of the sound (acoustic) space, there are hardly any cases where sound is utilized as spatial information grasping means like the actual world. In this case, the feedback sound with respect to the operation is a sound for informing user that user operation is securely carried out when, for example, user carries out designation operation by a pointing device, etc.
Moreover, since the virtually actualized space is mainly represented on a display (CRT, etc.) connected to the computer, etc., there is generally no means for obtaining information except for the elements displayed on that display.
Further, in the conventional general virtually actualized space, spatial action of virtual user and sound within the virtually actualized space, are not linked, and sound is not utilized as the information for judgment of circumstances.
Particularly, within the virtually actualized space, on the premise that it is used for the network service, attempts to utilize sounds for carrying out attraction by sounds such as a jingle sound, a theme song, or the like within the actual world have not yet been carried out. In addition, attempts to utilize sound for providing information in a manner of interrupt (request) (emergent contact (information) or message, etc.) in the case where there is limitation in the display area of the display have not yet been carried out as well.
This invention has been made in view of such actual circumstances, and its object is to provide a sound producing method and a sound producing apparatus which can utilize sound as spatial information grasping means in a manner as in the actual world within the virtually actualized space, which also permits an offer of information utilizing sound, and which can provide an increased advertisement effect.


BACKGROUND OF THE INVENTION

This invention is directed to a sound producing apparatus adapted for setting a virtual sound space corresponding to a virtual space displayed on a display unit to produce a sound characterized by the provision of underlying sound signal generating means for generating, on the basis
