The present invention relates to a three dimensional pointing device based on a finger gesture capable of sensing the finger pointing direction with a wearable method, and a presentation system using the same. The three dimensional pointing device comprises: a bridge including a three dimensional motion sensor to sense and notify of the finger pointing direction of a user in a three dimensional space; and two rings coupled to both ends of the bridge and including a wireless communication unit to wirelessly notify of a sensing result of the three dimensional motion sensor. The purpose of the present invention is to offer the three dimensional pointing device to generate and provide various control signals capable of reflecting intention of a user. |
