METHOD, SYSTEM, AND COMPUTER-READABLE RECORDING MEDIUM FOR PROVIDING INFORMATION ON AN OBJECT USING A VIEWING FRUSTUM

摘要

The present invention relates to a method, system, and computer-readable recording medium for providing information on an object using a viewing frustum. According to one embodiment of the present invention, a method for providing information on an object using a viewing frustum comprises: (a) a step of specifying at least one viewing frustum using a user terminal as a viewpoint; and (b) a step of calculating a degree of interest in the object by using the object, which is commonly contained in a first viewing frustum using a first user terminal as a viewpoint and in a second viewing frustum using a second user terminal as a viewpoint, as a reference. According to the present invention, the degree of interest in the object existing in the real word can be automatically calculated by using the viewing frustum as a reference, and additional information on the object can be provided differentially in accordance with the thus-calculated degree of interest in the object, thereby providing additional information on the object, which has captured the interest of users, to other users in an effective manner.
