Patent ID: 6944671

Claim:
A method of rapidly determining the transmission time and range of a position message under an Internet virtual reality environment, in which a timer scheme is employed for updating the virtual reality environment by using a timer to count a predetermined time value so as to transmit a message for informing all users participating in the virtual reality environment to update their positions when the time value has elapsed and the virtual reality environment reaches a predetermined inconsistency, the method comprising the steps of: (A) dividing a virtual scene into a plurality of blocks for determining an area of interest; (B) defining a block where a user is in and blocks neighboring to the block as a low interactive area of interest; (C) dividing each block of the low interactive area of interest into a plurality of sub-blocks; (D) defining a sub-block where the user is in and subblocks neighboring to the sub-block as a high interactive area of interest; and (E) transmitting a message to update the virtual reality environment based on the low interactive area of interest and the high interactive area interest when the predetermined time value for a respective one of the low and high interactive areas of interest has elapsed and the virtual reality environment reaches a predetermined inconsistency, wherein the predetermined time value for the high interactive area of interest is set shorter than that for the low interactive area of interest.
