TopIntroduction
In today's era of rapid internet development, smart home technology has gradually become an indispensable part of people’s lives (Fang et al., 2020). With the popularization and application of smart homes, indoor environment design is becoming increasingly important to daily life (Wang & Hou, 2021). The purpose of interior environment design is to make indoor spaces comfortable, beautiful, healthy, and safe, while the purpose of smart home technology is to achieve intelligent management and control of the indoor environment through intelligent devices and systems. The combination of indoor environmental design and smart home technology can provide users with a more comfortable, healthy, safe, and intelligent indoor life experience (Li & Song, 2022). At the same time, interior environment design has gradually become the focus of attention. Therefore, a new question for research is that of how to adapt indoor environmental design education to the development of smart home technology.
Smart home technology refers to any technology that utilizes technologies such as the internet, the Internet of Things, and artificial intelligence to achieve remote control and management of home devices, environment, and security. Smart home technology can automatically adjust the indoor temperature, humidity, lighting, sound, and other conditions on the basis of users' needs and habits (Kim & Lee, 2019). It can also interact with users through voice, gesture, facial recognition, and other methods, providing entertainment, health, education, and other services. Indoor environmental design refers to a design activity that plans and creates the functions, forms, colors, materials, lighting, and other elements of indoor space on the basis of human physiological and psychological needs, as well as social and cultural backgrounds. Indoor environmental design aims to create a safe, comfortable, beautiful, and personalized indoor space that meets people's needs in various aspects of life, such as work and leisure (Kim & Lee, 2018).
The integration of smart home technology with indoor environmental design is an interdisciplinary innovation model that can bring more possibilities and value to indoor spaces. For example, through smart home technology, indoor environmental design can achieve higher energy conservation and environmental protection. One way of doing this is the use of smart curtains, lighting, and air conditioning equipment to automatically adjust the indoor lighting and temperature according to outdoor weather and time changes, thereby reducing energy consumption and carbon emissions. Through smart home technology, indoor environment design can also achieve higher personalization and aesthetics. Using devices such as smart projectors, wallpapers, and picture frames, indoor patterns and colors can be changed at any time according to user’s preferences and moods, thereby increasing the fun and artistry of the indoor space (Zhang & Wang, 2020).
In 2015 the scale of China's smart home market was 40.34 billion yuan, a year-on-year increase of 41.0% (Yang et al., 2018). By 2016, the size of China's smart home market was 64.24 billion yuan, a year-on-year increase of 59.3%. As of 2017, the scale of China's smart home market had grown to 86.6 billion yuan. According to preliminary estimates, the scale of China's smart home market was expected to exceed 100 billion yuan in 2018, reaching about 128.5 billion yuan. It is estimated that the scale of China’s mart home market reached 142.2 billion yuan in 2019, showing a trend of increasing by 100 billion yuan year by year. If calculated according to the average annual compound growth rate of about 38.13% in the subsequent five years (2019-2023), we predict it will be found that the scale of China's smart home market exceeded 500 billion yuan in 2023. The statistics and forecast of China's smart home market scale from 2015 to 2023 are shown in Figure 1.
