▶Abstract

In daily life, we often hear the term "Amino acid," and they are essential for the human body. However, there are few opportunities to learn about Amino acid or to see them in real life.

Therefore, in this study, we developed a teaching material using mixed reality that allows users to create the structures of 20 types of Amino acids, consisting of Essential and Non-essential amino acids necessary for the human. The target users are those who have heard the term "Amino acid" but have little experience learning about Amino acid. In addition, by presenting the information necessary to learn about Amino acid in the virtual space during the experience, users can further understand Amino acid.

▶Purpose

This research aims to make learning relevant to everyday life and to make learning difficult themes fun by dealing with Amino acid, which go beyond the realm of organic chemistry and are important to life and humans. In addition, users can easily see the structures of Amino acid in a virtual space, which cannot be seen in real space.

Furthermore, it aims to address issues that arise in the study of organic chemistry in high school. For example, by using their own hands to create structures, users can understand the fundamentals of structures rather than memorizing them by rote.

They can also understand structures in three dimensions, which cannot be seen in textbooks, and observe them from various angles.

▶System Configuration

This is the system configuration. This system is composed of an HMD, a PC, a marker, and a foot pedal.

To operate the marker in the real space and to present the information necessary to learn about molecules and Amino acid in the virtual space, we use a video see-through MR HMD.

The markers placed on the board are used to track the position and rotation of the HMD.

The cube-shaped markers are used to display Amino acid molecules in the virtual space, and the distance and position of the markers are used to determine whether to attach or separate molecules, and where to attach them.

The foot pedal is used to determine whether to attach or separate molecules after the user operates the cube-shaped marker. It also plays a role in advancing the overall scenario.

The monitor is prepared so that people who are not wearing the HMD can see what the user is experiencing. This makes it possible to give advice to the user and learn at the same time.

▶Experience Scenario

A scenario consists of the following steps:

0) Choose Essential or Non-essential amino acid.

1) Choose the Amino acidyou want to make.

(Essential amino acid→9 types,​ Non-essential amino acid →11 types)

2) Create the structure of the chose Amino acid.

3)Choose whether to continue or stop or make another Amino acid.

During the experience, slides are presented that explain what Amino acid is, the characteristics of each Amino acid, and hints about their structures. This allows users to not only create structures, but also learn more about Amino acid.

▶Molecular simulation

As shown in figure, users can move the marker of the molecule to be attached close to the position of the molecule they want to attach and presses the foot pedal (right), and the molecules stick together.

As shown in figure, users can release the molecule by moving the marker of the molecule they want to release about 5cm away from the original position and pressing the foot pedal (center).

The name of the molecule and the direction in which it can be attached are displayed on the marker, so users can attach or release molecules accordingly.
