專利摘要(英)
Therefore, the object of the disclosure is to provide a head-mounted device that can alleviate at least one of the drawbacks of the prior art. According to the disclosure, the head-mounted device for reducing symptoms of cybersickness is adapted to be worn on a user’s head and to be used cooperatively with a head-mounted display. The head-mounted device includes a main shell and a stimulation unit. The main shell is adapted to be mounted on the user’s head, and includes a first tube body, a second tube body and a third tube body that are adapted to be respectively disposed at the top of the user’s head, the back of the user’s head and one of the user’s ears. The first, second and third tube bodies are arc-shaped, have arc-shaped central axes which respectively define imaginary first, second and third planes, and are fixedly connected to one another in a manner that the first, second and third planes are perpendicular to one another. Each of the first, second and third tube bodies has opposite closed ends. For each of the first and second tube bodies, each of the closed ends is adapted to be disposed proximal to a respective one of the user’s ears. The stimulation unit includes a first component, a second component and a third component. Each of the first, second and third components is received in a respective one of the first, second and third tube bodies, and is configured to be movable in at least one of rolling, sliding and flowing manners with low friction in the respective one of the first, second and third tube bodies. When rotation of the user’s head drives at least one of the first, second and third components of the stimulation unit to move in the respective one of the first, second and third tube bodies, the at least one of the first, second and third components is adapted to generate and transmit a stimulation force, through one of the closed ends of the respective one of the first, second and third tube bodies, to the user’s vestibular system for stimulating the user’s vestibular perception. When the at least one of the first, second and third components is composed of at least one rigid body, the stimulation force is proportional to an angular acceleration of the user’s head, a total mass of the at least one rigid body, and a radius of curvature of the respective one of the first, second and third tube bodies. When the at least one of the first, second and third components is composed of a fluid, the stimulation force is proportional to the angular acceleration of the user’s head, the radius of curvature of the respective one of the first, second and third tube bodies, an inner cross-sectional area of the respective one of the first, second and third tube bodies, and a density of the fluid.
