Abstract

An avatar display system in virtual space, an avatar display method in virtual space, and a computer program in which avatar motion data is thinned out within a certain time due to the circumstances of a system and is intermittently distributed. Accordingly, when avatars try to high-touch with each other, the avatars go too far before the hands touch each other in the transmission of coarse motion data, and thus a natural avatar operation cannot be performed. When avatars are intended to perform an operation with contact, such as a high touch operation between the avatars, as the avatars approach each other, a transmission interval in which data required for rendering avatars such as motion data, or rendered avatar data is transmitted from a server to a client terminal is made smaller, and a more natural avatar contact operation can be performed.

First claim

The invention claimed is:

1. An avatar display system in a virtual space for attaining computer graphic animation display of each avatar including a contact operation between the avatars on a display screen of each of a plurality of terminals by allowing users of the plurality of terminals connected through a communication line to share a three-dimensional virtual space, by allowing the avatar symbolizing each of the users to appear in the three-dimensional virtual space, and by distributing rendering data of the avatar including motion data to each of the plurality of terminals from a distribution unit,
wherein the avatar display system in the virtual space further comprises a distance information generating unit generating mutual distance information of each of the avatars in the three-dimensional virtual space, and a control unit provided in the avatar display system is configured such that an information amount per unit time of the distribution of the rendering data of the avatar including the motion data that is performed by the distribution unit is changed by changing a transmission interval for transmitting the motion data to the plurality of terminals from the distribution unit, in accordance with the generated mutual distance information,
wherein the control unit controls the information amount such that in a case where the generated mutual distance of the avatars is less than a threshold value set in advance, the information amount per unit time of the distribution is increased.

2. The avatar display system in the virtual space according to claim 1 , wherein at least one of the plurality of terminals includes a selection unit selecting a target avatar for generating the mutual distance information.

3. An avatar display method in a virtual space for attaining computer graphic animation display of each avatar including a contact operation between the avatars on a display screen of each of a plurality of terminals by comprising a step of allowing users of the plurality of terminals connected through a communication line to share a three-dimensional virtual space, of allowing the avatar symbolizing each of the users to appear in the three-dimensional virtual space, and of allowing a distribution unit to distribute rendering data of the avatar including motion data to each of the plurality of terminals,
wherein the avatar display method in the virtual space further comprises a step of allowing a distance information generating unit to generate mutual distance information of each of the avatars in the three-dimensional virtual space, and a control unit provided in the system is configured such that an information amount per unit time of the distribution of the rendering data of the avatar including the motion data that is executed in the distribution step is changed by changing a transmission interval for transmitting the motion data to the plurality of terminals from the distribution unit, in accordance with the generated mutual distance information,
wherein the control unit controls the information amount such that in a case where the generated mutual distance of the avatars is less than a threshold value set in advance, the information amount per unit time of the distribution is increased.

4. The avatar display method in the virtual space according to claim 3 , wherein the avatar display method further comprises a step of allowing a selection unit provided in at least one of the plurality of terminals to select a target avatar for generating the mutual distance information.

5. A non-transitory computer-readable medium encoded with a computer program for allowing a computer to execute each of the steps of the avatar display method in the virtual space according to claim 3 .
