Description
The present invention relates to a virtual reality system using a smart phone, and more particularly, to a virtual reality system using a smart phone that can alleviate the inconvenience of a specific human body part in use.
VR (Virtual Reality) is a virtual reality, which refers to a technique capable of creating a virtual screen or sound using special equipment and experiencing it in a similar way as if it were a reality through human senses such as sight or hearing.
In order to experience VR, several basic techniques follow, and a typical example is '3D'. Through stereoscopic visual stimulation, it gives the illusion that it is in reality. A sensor attached to the body is also needed. It grasps eye gaze and hand movements, and plays a role in connecting virtual screen to reality.
The devices that implement VR are the most diverse, and the easiest to see around us is the HMD product. HMD stands for Head Mounted Display and is a head display. Images transmitted separately through the left and right optic nerves give a clear three-dimensional effect as if they are spread out in front of you. And by analyzing my movements by the attached motion sensor and creating the screen accordingly, it is a virtual space, but gives the illusion of walking in reality.
A conventional VR system uses a sensor, a display, a camera, and the like, and is divided into two types. One is an independent VR system such as Oculus Rift and the other is a smart phone such as Galaxy VR (Galaxy VR) installed in an external optical device and installed in a smart phone VR system using smart phone using VR application.
1 is a block diagram of a conventional independent VR system.
Referring to FIG. 1, in the conventional independent VR system method, a system board receives an image output from a terminal such as a desktop or a notebook PC, and processes the image. Then, the liquid crystal display device (LCD device) displays the processed image and the displayed image is enlarged through the optical system.
2 is a block diagram of a conventional VR system using a smartphone.
2, a conventional VR system using a smart phone is a system in which a smart phone is connected to a predetermined device having an optical system and the image of the smart phone is enlarged through an optical system equipped with a predetermined mechanism .
An example of a conventional VR system using a smart phone is disclosed in Korean Patent No. 10-1419007 (hereinafter referred to as "prior patent document").
The prior art document is a head-mounted stereoscopic apparatus for a smartphone, and more particularly, to a stereoscopic apparatus for displaying a two-dimensional image displayed on a smartphone as a three-dimensional image.
