Description

Online Learning Apparatus and Augmented Reality And Method Thereof}

The present invention relates to a method for implementing augmented reality and an apparatus using the same, and to a method for implementing augmented reality using an adaptive digital marker and an apparatus using the same.

Augmented Reality (Augmented Reality) creates a new environment by combining the real world that the user sees with the virtual world with additional information. The augmented reality system that combines the real environment and the virtual environment has been researched and developed mainly in the United States and Japan since the late 1990s. Augmented reality, a concept that complements the real world with the virtual world, uses a virtual environment made of computer graphics, but the main role is the real environment. Computer graphics serve to provide additional information needed for the real world. It means that the distinction between the real environment and the virtual environment is blurred by registering the 3D virtual image with the real image which the user sees. Virtual reality technology immerses the user in the virtual environment and cannot see the real environment. However, augmented reality technology, which is a mixture of real and virtual objects, provides a better sense of reality by allowing the user to see the real environment.

A general method of augmented reality is largely a marker based method for implementing augmented reality using AR (Augmented Reality) markers and augmented reality using feature points or 3D models collected from objects in the real world. It is divided into a marker-less method. In addition, to implement augmented reality requires a camera that can receive a real image and a display device capable of displaying a real image and a virtual image.

The simplest form of augmented reality is applied in the fields of entertainment and news. If you're forecasting on TV, you'll see that the weather map in front of the weather caster changes naturally. Actually, the weather cast is in front of the Blue-Screen.

Virtual images that are standing and computerized create a virtual studio environment for augmented reality.

In addition, 3D data of the patient is acquired in real time through indirect inspection such as magnetic resonance image, computed tomography image, and ultrasound image, and then the acquired data is rendered in real time and overlapped with the patient. By expressing it, the surgeon can perform a patient's operation smoothly. A virtual image can be displayed on the visor of the pilot's helmet or on the windshield of the cockpit to inform the pilot of a lot of information necessary for the operation.

Recently, as education on a language or a foreign language becomes more common, various learning systems that can be learned at home besides learning institutions such as an external institute are appearing. In this regard, the recent learning systems are being manufactured to make learning more effective by adding various functions in accordance with the development of high technology, instead of pictures or letter cards depicting the characteristics of people, animals, and objects of the past. Currently, the most widely used learning system in the learning system is a system that performs various learning on the PC by receiving various contents to the PC using the Internet.

However, the conventional learning system mostly focuses on the interaction between the screen and the mouse or the keyboard on the PC to fix the learning user in front of the PC screen, and the learning is performed in a static state as if the user clicks the mouse or the keyboard with a finger. There is a problem that can interfere with the user's physical development. In addition, since the learning on the PC can be learned only by an input means such as a mouse or a keyboard, such a simple and repetitive operation may make the user easily get tired of it, and it is difficult to continuously perform step by step learning. There is a disadvantage that effective learning cannot be performed for users who are not familiar with PC-related tools such as a mouse.
