Abstract
There is provided an information processing device including: a global map acquiring unit that acquires at least a part of a global map representing positions of objects in a real space where a plurality of users are in activity; a local map generating unit that generates a local map representing positions of nearby objects detectable by a device of one user among the plurality of users; and an updating unit that updates the global map based on position data of objects included in the local map.
Claims14
An information processing device comprising:
- a global map acquiring unit that acquires at least a part of a global map representing positions of objects in a real space where a plurality of users are its activity;
- a local map generating unit that generates a local map representing positions of nearby objects detectable by a device of one user among the plurality of users;
- and
- an updating unit that updates the global map based on position data of objects included in the local map.
A map update method for updating a global map representing positions of objects in a real space where a plurality of users are in activity, performed by an information processing device, the method comprising steps of:
- acquiring at least a part of the global, map;
- generating a local map representing positions of nearby objects detectable by the information processing device;
- and
- updating the global map based on position data of objects included in the local map.
A program for causing a computer for controlling an information processing device to function as:
- a global map acquiring unit that acquires at least a part of a global map representing positions of objects in a real space where a plurality of users are in activity;
- a local map generating unit that generates a local map representing positions of nearby objects detectable by a device of one user among the plurality of users;
- and
- an updating unit that updates the global map based on position data of objects included in the local map.
An information processing system comprising:
- a server device that stores a global map representing positions of objects in a real space where a plurality of users are in activity using a storage medium;
- and
- an information processing device possessed by one user among the plurality of users, the information processing device including
- a global map acquiring unit that acquires at least a part of the global map from the server device,
- a local map generating unit that generates a focal map representing positions of nearby objects detectable by the information processing device, and
- an updating unit that updates the global map based on position data of objects included in the local map.
