Abstract: Objective: To analyze the development status of wearable devices and reveal the reasons behind the current development of the wearable device market. Methods : Based on the design case of a variety of wearable devices, combined with the background of product design development, research through human core needs. Conclusion : Through the analysis of the commonality between sports and health products and wearable devices, it is concluded that wearable devices will inevitably explore a lot in the field of sports and health, and finally reach the realm of “nothingâ€. Exercise has always been an important form of human health. As human beings continue to pursue the quality of life, the design of sports and health products is constantly evolving. The advancement of technology has made more and more products smaller and lighter until they are Called "wearable devices", sports and health products and wearable devices must come together in today's product design, and there is a broad space for development. 1 Categories and characteristics of wearable devices and sports and health products 1.1 The macro trend of product design “none†In the development process of industrial design, from the mass production of early basic living materials to the modern intelligent technology revolution, the people-oriented concept has been running through it. Based on this, the products used by human beings are constantly becoming easier to use, more automated, and more intelligent, but no matter how they develop, people, not slaves of products, in modern life surrounded by countless products, People are also trying to get rid of the shackles of products, which has always led the direction of technological development. Taking electronic computers as an example, the earliest electronic computers were born in the 1840s, with a volume of more than 150m2, and the quality is basically above 30t. By the 1880s, electronic computers had been included in the category of personal consumption, and their size could be reduced. To be placed on the desktop (the only component that is constantly increasing in size is the screen). At the same time, a novel term "computer" is rooted in everyone's brain. With the advent of laptops, smart phones, and tablets, plus the combination of wireless networks and wireless charging, today's products with computing power have Small enough to be worn, all this is the result of human pursuit of simple life. In the long run, the author believes that people's ultimate pursuit of products is "nothing." In the future, people should be able to use the services brought by technology anytime and anywhere without carrying any products. The required products will be publicized in large quantities and exist in life to jointly build a “smart space†to achieve product-free constraints. Ideal state. 1.2 Similarities and differences between sports and health product design Exercise and health are a group of closely related elements. Exercise for health, exercise is also to maintain a healthy state, exercise is a method, and health is the ultimate goal. Sports products appear as apparel as the main product category. With the continuous development and refinement of people's sports types, sports products are on the way from the clothing era to the equipment era, and more and more professional sports products let More people enjoy a better sports experience; health products are based on medical devices, and are constantly developed according to the medical and human needs of health. According to the current definition of health, health can be said to be healthy. Products are also moving from the equipment era to the clothing era. More and more health products are becoming more affinitive. 1.3 Design intersection under the user experience traction The development of sports products and products is the same, but sports products will appear after people's living standards reach a certain level, and gradually refined. Unlike other types of products, exercise itself belongs to human original activities, so the purpose of early sports products is not to make people exercise, but to exercise better, such as sportswear, which can be defined as sports products because they are really With certain features, such as better breathability, thinner and lighter. In modern times, people in urban life are getting smaller and smaller, and how to motivate people to move into a breakthrough in sports product design. Health products have a broader definition than sports products. Based on human pursuit of quality of life, health products, especially those designed based on medical devices, pay more attention to the psychological feelings of patients and doctors as users, based on the completion of physical functions. Products that relax and make doctors feel good use become the mainstream of the market. On the whole, sports and health products have come to a new field of integration under the guidance of the central idea of ​​user experience. Under this background, the similarities between the two types of product design will better serve the users under the force of synergy. And the differences between them, based on the central idea of ​​user experience, will also have more detailed and deeper design innovation. Sports and health products are designed in the same way: strict human-machine research, precise fit, parameterization and data acquisition. The difference between sports and health products design is that the design of sports products emphasizes virtual transfer, innovative sports, and fun motivation; the design of health products emphasizes companionship, privacy, security and reliability. The design of the insulin syringe is a typical case of companionship and privacy. See Figure 1 (picture from the official website of HUMAPEN), an insulin portable syringe designed by IDEO for HUMAPEN·SAVVIO. From the appearance, it is impossible to distinguish the difference between it and the pen. This type of product is more than one in the field of insulin syringes, which is why they call this syringe an insulin pen. The author believes that there is a big gap between the product categories of sports and health, and there are also differences. From the perspective of vocabulary concepts, the range of health products is broader. Wearable devices, from the intersection of the two to explore, is also the inevitable way.
