Virtual Projection Display for Public Information of Tourist Cave
관광동굴의 대중홍보용 가상 프로젝터디스플레이
Abstract
Nowadays, power-point slides are the common form of presentation at meetings or lectures. However, when it comes to explanation and demonstration, it is difficult to do so effectively on a screen that is projected from a projector. This drawback might lower the level of quality of communication between the speaker and his audience. On top of this, the speaker is constrained to a certain amount of space. Based on this fact, in this work the constructed device can be used as an extension for the existing functions and makes up for the disadvantages of projected presentations by means of a web camera which enjoys ease of use and is economically priced. It would be also used as a virtual projection display for information of tourist cave in the field.
