  • Patent number: 9959021
    Abstract: A map server includes a user list obtaining module configured to obtain a user list in a 3×3 grid; a distance queue generating module configured to obtain distances between users and a current user in the user list, and generate two distance queues corresponding to preset distance ranges according to the distances, the distance queue including users in the user list whose distances from the current user are in a corresponding distance range; a visual field list generating module configured to select users from the distance queue into a visual field list according to a weight corresponding to the distance queue. Further, a visual field controlling method and system, and a computer storage medium, may be used to classify users in the 3×3 grid into distance queues using distance ranges, and select users into the visual field list according to the weight, thereby reducing pressure of the server.
