With the rapid progress of technologies such as built-in sensors, computer vision, and human-computer interaction, digital technology has continuously improved its ability to measure physiological conditions and physical activities, which can better capture human behaviors such as eye movement, tactile perception, and emotional feedback. In addition, people's demand for digital life continues to rise, driving the accelerated development of human-computer interaction interfaces towards humanization, The interactivity of virtual reality/augmented reality wearable devices is constantly improving. During this period, Apple is developing a new type of virtual reality/augmented reality (VR/AR) wearable device - the smart ring - which has once again attracted market attention to VR/AR wearable devices. It is reported that users can interact with VR/AR scenes by wearing this smart ring. What are the different types of VR/AR wearable devices currently available? How do these wearable devices interact with the real world? Is the VR/AR wearable device industry still promising despite the slowdown in the metaverse's popularity? Handheld and headworn are the two main types. With the continuous innovation and development of digital technology, the VR/AR wearable device industry is developing rapidly, with an increasing number of categories and functions, and the product market capacity is showing a rapid growth trend. From the perspective of application areas, VR/AR wearable devices mainly come in two types: handheld and headworn. Handheld VR/AR wearable devices, combined with hand movements, can perform related operations in VR scenes, such as screen switching, page scrolling, document browsing, and image stacking, providing users with a more realistic and immersive experience. The main product types include smart rings, touch bracelets, data gloves, etc. At present, this type of device is showing a trend of lightweight, miniaturization, and multifunctional development, with strong portability, high practicality, and fast synchronization. It can help designers, architects, engineers, and other groups quickly start VR scenes, improve the spatial design and innovation abilities of practitioners, and achieve extensive virtual collaboration. Headworn VR/AR wearable devices, by combining with head and eye movements, leave users in a relatively closed state of their senses to the real world, providing them with an immersive experience, and implementing relevant operations in the virtual world through tools such as feedback gloves. The main product types include helmets, glasses, eye masks, etc. At present, this type of device is showing a trend of fragmented and lightweight development, with strong sense of presence and high interactivity. It is suitable for fields such as gaming, training, medical treatment, manufacturing, science popularization, etc. It can help users or relevant industry practitioners carry out related activities in a simulated environment that is close to reality, such as manipulating virtual objects, remote device maintenance, etc. Technological progress continues to improve interactivity. VR/AR wearable devices are essentially tools that can visually quantify and extend human physical activity. With the rapid progress of technologies such as built-in sensors, computer vision, and human-computer interaction, digital technology has continuously improved its ability to measure physiological conditions and physical activities, which can better capture human behaviors such as eye movement, tactile perception, and emotional feedback.
