ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a program providing medium, a shared virtual space providing apparatus, and a shared virtual space providing method. More particularly, the present invention relates to a program providing medium, a shared virtual space providing apparatus, and a shared virtual space providing method that are adapted to remotely acquire information associated with the growth process of a virtual creature and remotely breed the same.
2. Description of Related Art
A cyberspace service named Habitat (registered trademark) is known in so-called personal computer communications services such as NIFTY-Serve (registered trademark) of Japan and CompuServe (registered trademark) of US in which a plurality of users connect their personal computers via modems and public telephone networks to the host computers installed at the centers of the services to access them in predetermined protocols. Development of Habitat started in 1985 by Lucas Film of the US, operated by Quantum Link, one of US commercial networks, for about three years. Then, Habitat started its service in NIFTY-Serve as Fujitsu Habitat (trademark) in February 1990.
In Habitat, users can send their alter egos called avatars (the incarnation of a god figuring in the Hindu mythology) into a virtual city called Populopolis drawn by two-dimensional graphics to have a chat (namely, a realtime conversation based on text entered and displayed) with each other. For further details of Habitat, refer to the Japanese translation “pp. 282-307” of “Cyberspace: First Steps,” Michael Benedikt, ed., 1991, MIT Press Cambridge, Mass., ISBN0-262-02327-X, the translation being published Mar. 20, 1994, by NTT Publishing, ISBN4-87188-265-9C0010.
In the conventional cyberspace systems operated by personal computer communications services such as mentioned above, a virtual street and the inside of a room for example are drawn in two-dimensional graphics. Therefore, moving an avatar in the depth direction is realized simply by moving it up and down in the background of the two-dimensional graphics. This results in a poor expression in simulating walking and movement in a virtual space. Also, the two-dimensional virtual space in which own avatar and the avatar of another user are displayed is viewed from a viewpoint of a third party, thereby impairing the sense of simulated experience.
To overcome this drawback, a capability that enables a user to walk as desired with the viewpoint of the avatar of the user in a virtual space represented in three-dimensional graphics is realized by use of a three-dimensional graphics data description language called VRML (Virtual Reality Modeling Language) as disclosed in Japanese Patent Laid-open No. Hei 9-81781 corresponding to U.S. patent application Ser. No. 678,340. Considerations about various cyberspaces in which chat is made by use of the avatar of a user are described in NIKKEI Electronics, Sep. 9, 1996, No. 670, pp. 151-159.
Recently, breeding simulation games for breeding tropical fish and a virtual creature having artificial intelligence living in a virtual world for example have come to be available as personal computer software programs. A product is also known that displays a simulated pet such as a dog or a cat on an electronic notepad to enjoy the process of its growth (refer to NIKKEI Electronics, Apr. 7, 1997, No. 686, pp. 131-134). In addition, “Tamagotchi” (registered trademark) developed and commercialized by Bandai Co. is widely known that is an egg-sized portable virtual reality pet with a breeding simulation game program as mentioned above incorporated.
Virtual reality pets of this type have a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory) and so on mounted on a single-chip LSI (Large Scale Integration), a breeding simulation game program being stored in the ROM, the figure and state of the pet being displayed on an LCD (Liquid Crystal Display) device. The user gives such instructions by operating buttons as “feed” and “broom” for example necessary for breeding the virtual reality creature as a pet. As a result of caring, the virtual reality creature displayed on the LCD grows stepwise from an egg to a chick to a grown-up bird for example in its external view.
The virtual reality creature is programmed such that proper instructions given help the virtual reality creature grow without problem and improper instructions given make it sick or, in the worst case, die. Further, the virtual reality creature is programmed to make various requests based on the time elapsing from its birth provided by an incorporated calendar timer. For example, in the nighttime zone, the virtual reality creature requests a sleep and, in the mealtime zone, it requests food. In other times, the virtual reality creature requests, at random, snack and play for example. If the user fails to answer these requests properly, the growth of the virtual reality creature may be retarded or its character worsens. If the user answers properly, the life of the virtual reality creature is lengthened.
Meanwhile, Japanese Patent Laid-open No. Hei 07-160853 corresponding to U.S. Pat. No. 5,572,646 discloses a technology applicable to an electronic notepad for example for displaying images according to the growth processes of a virtual reality creature such as an animal or a plant. To be more specific, bit-map images representing the growth processes of a plant character for example are stored in the ROM in the electronic notepad. The plant character according to the degree of growth is displayed on the LCD of the electronic notepad and, at the same time, characters representing plant growing elements (water, light, and fertilizer for example) are displayed. Necessary amounts of these growing elements are inputted by operating corresponding keys on the electronic notepad. The inputted values are set to a water amount register, a light amount register, and a fertilizer amount register respectively in the RAM of the electronic notepad. Based on the values set to these registers, a new degree of growth is computed. Then, the plant character corresponding to the computed degree of growth is read from the ROM to be displayed on the LCD. Thus, the plant growth process according to the state of cultivation by the user is displayed.
However, the above-mentioned virtual reality pet or the electronic notepad for breeding a virtual creature described in Japanese Patent Laid-open No. Hei 07-160853 supposes application to a standalone apparatus that operates as one independent unit. Therefore, the existing space or breeding environment of the virtual creature is concluded in that appararus. In the above-mentioned technologies, a programmed virtual creature is handled as one entity and a breeding simulation game progresses between the owner or keeper of the virtual reality pet and the same in a one-to-one relation. This presents problems that the owner or other users cannot remotely acquire the information associated with the growth process of the virtual creature and remotely breed the same.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a program providing medium, a shared virtual space providing apparatus, and a shared virtual space providing method that allow the user to remotely acquire the information associated with a virtual creature and remotely breed the same.
In carrying out the invention and according to one aspect thereof, there is provided a program providing medium described in claim 1, the program including the steps of: controlling a communication control table in which a user of the client apparatus who is a keeper of the virtual life object, a notification method of sending a message to the keeper, and an address of contact of the keeper are registered; and sending the message to the address of contact according to a status transition of the virtual life object by use of the notification method registered in the communication control table.
