Research on the design of intelligent flowerpot science and education toys

. With the development of science and technology, children's attention has gradually shifted from accompanying their childhood toys to electronic entertainment products. Gradually, children have also stepped into the ranks of "bow heads". In order to let children put down their mobile phones and go out of the house, the author germinated the idea of integrating nature into children's toys. Based on the cognitive characteristics of 3-6-year-old preschool children, this study takes children's science and education toys as the research object, analyzes and summarizes the development trend of intelligent science and education children's toys at home and abroad, finds new innovative ideas for the functions and forms of intelligent science and education children's toys, combines the cognitive characteristics of preschool children with the mysteries of nature, and hopes to help children understand colors and respect nature, Learn more about plants in nature.


Research background
With the improvement of people's quality of life, parents attach great importance to the development of children's intelligence. They want to give full play to their children's abilities in all aspects and tap their potential. Therefore, science and education intelligent toys that combine functionality, interest and intelligence respond to parents' desire to improve their children's ability, as shown in Figure 1. However, the play ability of toy products on the market is not high, and children's attention will soon shift from toys to electronic entertainment products, leading to the phenomenon of "low age" of "low head" people, which tends to expand [1] , which does not prohibit parents' concerns about children's growth, such as low vision, early muscle degradation, easy to induce autism, loss of independent thinking ability, etc. Therefore, it is very important to choose a new and sustainable science and education toy that can help children put down their mobile phones and go to the outside world to attract children's attention and seize the childlike innocence of children. Factors of concern and purchase of children's toys.

The content of cognitive psychology
In the research, the behavior process of human cognition is actually an information processing process similar to machine processing, execution and output [2]. That is, people feel things through human cognition in the process of cognition, and improve the information of things from simple to complex through contact and viewing. According to the cognitive psychology analysis of children's cognitive and behavioral characteristics, children's age can be divided into six stages, as shown in Figure 2. Among them, the pre-school age of 3-6 years old is the golden period for the development of children's cognitive ability, and the early education received by pre-school children has a very important impact and Inspiration on children's growth. At this stage, children's cognitive development is in the pre conceptual stage of thinking, which is one of the strongest stages of children's learning ability. Cognitive development is mainly reflected in the development of feeling, perception and attention. Children understand the world through their own cognition and feeling [3]. Sensory system refers to the ability of the brain to interpret, screen, process and respond to sensory information from various sensory organs, as shown in Figure 3 [4] . This article mainly elaborates from three aspects of children's vision, touch and hearing. In terms of vision: for children to recognize the world and judge the surrounding environment, it is mainly through the intuitive feeling generated by vision to capture the color of the surrounding environment. Vision is a very important organ and the most sensitive organ for children. According to the analysis of psychological experts, in the face of a color figure, children will notice the color first and then the figure. Similarly, Montessori, a world-renowned child educator, believes that "beautiful colors not only help children concentrate, but also restore their tired energy [5] . That means the color is right.
Children have a strong attraction, which is why the graphic color is easier for children to accept and understand than the text; In terms of touch: preschool children's perception development has been very perfect. Children can feel the material texture, weight, temperature, etc. of objects through finger touch. The tactility of materials often brings different feelings. For example, metal is smooth and hard, giving people a cold and heavy feeling; Cotton is a rough and soft image, giving people a simple and light feeling. Therefore, in the design of children's toys, we should choose lighter materials for design; In terms of hearing: hearing is an important way to receive external signals. In the process of interacting with self perception through vision and touch in daily life, people can quickly receive information with hearing. At this time, preschool children's hearing has been well developed and can use hearing to prompt children and attract children's sight and attention.
To sum up, the design of intelligent science and education toys for preschool children aged 3-6 needs to pay attention to: • It is necessary to carry out sensory impact from three aspects of vision, touch and hearing to fit the children's heart, • It is necessary to strengthen the knowledge reserve and add the daily review clock, • Strong interaction ability is needed to make children have a good sense of experience when using, • Children need to satisfy their desire for selfexpression.

Overview of children's intelligent science and education toys
In the intelligent era of rapid development of science and technology, intelligent toys are a new type of toys with excellent interactive user experience. Intelligent toys full of sense of science and technology are an innovative direction of toy product design and the mainstream of future toy market development [6] . Intelligent science and education toys are educational, intelligent entertainment interactive toys. The biggest feature is that it can provide rich, interesting and novel interactive ways when children use it, and can promote the healthy development of children's physical and mental health, and expand their brains. [7] In use, it can make the toy entities and users communicate with each other, with a strong sense of experience, which is also the characteristics of science and education intelligent toys. Intelligent science and education toys can combine some simple scientific knowledge with traditional toys. It is an innovative toy different from traditional toys. It can also enable children to quickly accept and understand AI in the process of use. This is also an entry point of AI. Such an entry point not only promotes the development of children's toy market, but also expands the application of AI in different product development, It has promoted the development of social economy and accelerated the popularization and use of artificial intelligence in public life.

Case analysis of science and education toys at home and abroad
China's toy consumption data is huge. The average domestic child spends nearly 400 yuan on early childhood education toys every year. Of the more than 300 million children in China, 80million urban children spend more than 30 billion yuan on early childhood education toys every year. Plus 250million rural children's early childhood education toy consumption, Chinese children's early childhood education toys spend more than 50billion yuan every year [8] . In foreign countries, the market of children's intelligent science and education toys has developed perfectly and has maintained an upward trend. In 2019, its total retail value was $26.6 billion, followed by North America (including the United States), with a total retail value of $16.7 billion [9] . It can be seen that toys with the theme of education are more likely to become the focus of the market and are demanded by the market. The following are the three science and education toys at home and abroad that we are looking for: DIY plant sunshine room, microscope exploring nature suit, and interactive point reading exploring solar system suit, as shown in Figure 4 [10] . DIY plant sunshine room is a small manual DIY science experiment set toy that allows children to experience the fun of planting and harvesting. The toy set includes: a variety of plant flower seeds, planting tools and beautiful and exquisite transparent sunshine room; The microscope exploration natural suit is a children's microscope suit that allows children to explore and observe the other side of things by themselves and records the scientific exploration of the micro world by mobile phones; The interactive point reading solar system exploration kit is a scientific and educational toy that uses a point reading pen to touch any planet on the solar system planet chart and understand various background knowledge of the planet. According to the following three types of science and education toys, it can be found that the existing science and education toys for children at home and abroad are designed to meet the desire of children to explore and seek knowledge, and convey scientific knowledge through lighting (visual), sound effects (auditory) and click reading (tactile). They are not displayed in a single way, but integrate multiple senses to help children learn and help children achieve psychological and physical pleasure in play.

Design positioning
User orientation: This study selected pre-school children aged 3-6 as the research object. With the use of children's intelligent flowerpot science and education toys, it can help children's physical and mental health development, promote children's harmony with their parents, and realize the sustainability of children's toys. Environmental positioning: the use environment is indoor and outdoor. Considering the cognitive behavior characteristics of preschool children, the children's intelligent flowerpot science and education toy product is equipped with a mobile handheld pan tilt part and a smart flowerpot for home use, which is convenient for children to carry out shooting, learn science popularization and planting at home.
Function orientation: as a scientific and educational toy product of children's intelligent flowerpot, the first condition to be satisfied is that playing the role of intelligent science and education can help children's physical and mental health development and improve children's learning and cognitive ability. The second is to combine the characteristics of the timing and quantitative intelligent irrigation system of the intelligent flowerpot, so that children can develop good living habits, separate children from the ranks of "low headed people", alleviate the troubles of parents, promote family harmony, and promote the healthy development of society, so that children can become the "Encyclopedia" of the plant world.
Color positioning: preschool children aged 3-6 years old have perfect visual development and are curious about the color of the surrounding environment. The product combines the structure of the intelligent flowerpot with the needs of indoor and outdoor use environment. Therefore, the color matching of the handheld PTZ is simple black-and-white and gray. The toy as a whole is close to the natural green and clean white, which can be well integrated into the home environment in a simple and lively way.
Material orientation: the material of the product should be safe, fall resistant and non-toxic, because preschool children will inevitably have the possibility of biting the toy in their mouth or falling to the ground. The main material of the product is ABS plastic, which is light and easy to shape, and PC (acrylic plastic) with good light transmittance and toughness.

Design practice
According to the cognitive and behavioral characteristics of pre-school children, the intelligent flowerpot science and education toy iplant-2 has been innovated in various parts. The intelligent flowerpot science and education toy iplant-2 is mainly divided into four parts: the top cover and the handheld PTZ, the flowerpot body, the base and the PC transparent protective cover, as shown in Figure 5. The design of the handheld PTZ mainly lies in that it has two lenses, one for shooting and the other for projection. The camera can rotate up, down, left and right for shooting, which is convenient and easy to operate; The concave convex printing of stair design and leaf and branch shape abstract design is carried out on the flowerpot body, which can emit light at a specific time. The use of luminous technology to visually stimulate children, arouse children's curiosity about nature, and help children seriously complete the "task" prompted by iplant-2 -to explore the nature of plants, upload information to the cloud album, water and fertilize plants first, and witness the light of toys every time; The appearance of the ipplant-2 refers to the image of the "crystal ball music box", and a "forest house" is built in the middle of the flowerpot, so that children can feel that there is a place where their hearts can be reposed when planting, and they can build their own "secret garden", and the whole shape is dreamy and beautiful; Finally, connect the ipplant-2 to the network to obtain relevant information and data: understand plant species, habits, reservoir water volume, soil moisture, etc., and provide voice prompts. Check the "secret letter" of the forest cabin on the app to share exploration experience, upload a cloud photo album, record every plant science and technology knowledge, complete the daily clock out task, and "earn" Secret Forest building materials funds, as shown in Figure 6.

Conclusion
As parents pay more and more attention to the cultivation of children and the formation of children's behavior habits, there is a wide market demand for smart toys guided by science education. However, the phenomenon of "low age" of "low head" in society has not only brought trouble to parents but also hindered the development of society. Based on the analysis of relevant contents of cognitive psychology, the intelligent flowerpot science and education toys have obvious educational and interesting features in terms of function and shape compared with the science and education toys on the market. It allows children to play from indoor to outdoor, and double promotes and helps children explore nature, meeting the cognitive characteristics of preschool children exploring the world.
