Description

Chemical experiment system using virtual reality The present invention relates to a virtual reality education system applicable to chemistry experiment education where direct practical training is difficult. Due to recent advancements in IT and other fields, Virtual Reality (VR) and Augmented Reality (AR) technologies are developing and are increasingly being applied to daily life. To implement VR or AR, various devices are required, such as motion recognition devices that detect user movements, and display units that simultaneously visualize real and virtual objects while receiving information from the motion recognition devices to visually implement functions related to those motions. Examples of motion recognition devices include shoes, gloves, and clothing; among these, gloves are a representative example worn on the user's hand to control or recognize motion. These immersive technologies utilizing virtual or augmented reality are being widely applied in the field of science education, particularly in areas such as chemistry and biology where actual experiments are difficult. While science experiments are a crucial part of learning, some are dangerous, and improper execution can jeopardize student safety. For instance, considering the actual experiment of acid-base neutralization, the inherent dangers of these substances often force the lesson to be passive instruction or merely a demonstration by the teacher. Consequently, students may fail to fully understand the experimental process, leading to reduced learning effectiveness or a loss of interest in science experiments. There is a need for technology that can apply recently developing virtual reality technology to dangerous science experiment education where real-world experience is difficult. FIG. 1 is an exemplary view of a chemical experiment system using virtual reality according to the present invention, and FIG. 2 is an exemplary view of a glove for a virtual reality controller used in the system of the present invention, and FIG. 3 is an exemplary view of a beaker used in the system of the present invention, and FIG. 4 is an exemplary view of a stirring rod used in the system of the present invention, and Figure 5 illustrates the stirring of the liquid inside the beaker with the stirring rod. The objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. Additionally, the terms used are defined with respect to their functions in the present invention, which may vary according to the user's intent or practice. Therefore, the definitions of these terms should be based on the content throughout this specification. FIG. 1 is an exemplary view of a chemical experiment system using virtual reality according to the present invention. The user wears a head-mounted display (HMD, 110), which is mounted in the same way as glasses, goggles, or a helmet and is configured to display necessary content images to the user, providing the user with a highly immersive experience. In one embodiment, the HMD may be connected to a computer or a cloud server. In the drawing, 120 is a glove for the controller of the present invention, and 200 is a plurality of cameras arranged to photograph the user. In one embodiment of the present invention, the method, system, image import object, sensor, and the globe as an associated interface object are configured to process data configured to be rendered substantially in real time on a display screen. For example, when a gesture is performed, such as when a user's hand moves, a finger bends, multiple fingers bend, or a finger touches another finger, such changes in position are configured to be displayed in real time on the display. In the system of the present invention, the user's hand position, detected pressure, contacted fingers, and gestures are used to interact with a virtual world scene, a shared virtual space, or a character that is an extension of the user in the real world, or simply to provide a method for contacting, supporting, playing, interfacing, or communicating with a virtual object or an object corresponding to a document, text, image, etc. appearing on a display screen. In addition, in other embodiments, the globe may be equipped by multiple users. In these embodiments, each user may use one or two globes. By using a cloud system in a shared space from a remote location, users may be co-located and multiple users may participate simultaneously. Among the shared users, movements made by one user's hand are displayed to other users as actual users moving objects or items in the shared workspace, and users wearing gloves are displayed as pointing at specific objects, touching specific objects, or manipulating specific objects in the virtual space. In order to detect such movements, the present invention utilizes a globe (120) that includes one or more sensors
