Electronic Games (Electronic Games) refers to an interactive entertainment method based on electronic devices. The main features are interactive and analog. Since its inception in the late 1960s, applications have expanded from entertainment to military, education, and medical . Thus, the concept of Serious Games came into being. That is to use the form of the game to achieve serious goals (such as education, training, treatment).

Serious games were first used in military training. The world's first serious game was the American Army's "America's Army" developed in 2002. After its appearance, it attracted widespread public attention. Since then, it has gradually expanded to other areas such as school education, skills training, and health care. This article focuses on the application of video games in the field of medical and health, and assists in the research of disease treatment.

1. Why can video games be used in the medical field?

Video game-assisted therapy refers to the use of video games as a therapeutic medium and carrier, applying psychology theory to enable patients to express and vent their emotions, experiences and behaviors in the game, thereby obtaining a kind of satisfaction, growth and psychotherapy. Adjuvant therapy (Wang Ran et al., 2013). It is mainly achieved by using human-computer interaction to intervene in patients' cognitive and behavioral skills.

Norman D. proposed a video game interactive circle model (see Figure 2) for all WIMP interfaces (W-windows, I-icons, M-menu, P-pointing devices). The basic cyclic process is: The software program outputs the current state of the system through the output device, and the user analyzes the current state (a). If it is necessary to change the state of the current system, the instruction information is input through the input device (b), the software The system accepts/understands/evaluates these instructions (c), then changes its internal state (d), and finally notifies the output device to update the display information (e). At this point, a loop is completed and the user sees the updated information and knows that the system status has changed. The user can start another loop again if needed.

In the interaction loop of FIG. 2, the user's reaction to the screen information is the start and end point of a single loop, and the user decides whether to start the next loop again, so the human-computer interaction is a user-led interaction process. The medical experts can intervene in the user's cognition and skills by purposefully and purposefully controlling the computer's response to the user's response and giving feedback to the user.

For example, in 2014, Galna B. et al. developed a somatosensory game based on the Microsoft Kinect platform to help Parkinson's patients perform posture gait recovery (see Figure 3 for a design sketch). The researchers set up 12 different levels of difficulty, multi-directional grasping and stepping tasks to train the user's ability to control posture gait. For example, if the user sees the interface of Figure 3, it will make a gesture of reaching out; this behavior is transmitted to the computer through the sensor; after the computer accepts the instruction, it performs information processing: whether the user can get the apple on the left side; Feedback: If you can, the apple disappears and adds a point to the achievement column in the lower right corner. If so, the researcher guides the user through a prescribed action.

Cosmetic Ingredients

Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
