Haptic feedback is becoming more common, especially on smartphones and game consoles, and is used primarily to enhance the effects of certain actions. This technique requires direct contact between the device and the user's hand and is achieved by mechanical or acoustic vibration. However, researchers at the University of Bristol in the UK have developed a tactile feedback technology that can be implemented by ultrasound.
When the ultrasound is presented in a complex pattern, it can cause airflow disturbances, and this trait can be used to create a 3D holographic shape. These shapes can be felt by the skin via airflow disturbances.
Researchers claim that this new technology can be used to help surgeons with the ability to sense the presence of tumors through mechanical feedback in CT scans.
Dr. Ben Long, a researcher in the Computer Science Interaction and Image Group at the University of Bristol, said: "The holographic shapes that can be touched and the immersive virtual reality allow you to feel the complex touch in free space and control it accordingly. This technology is expected to make this situation a reality."
A laminate lighting system is a special lighting technology used to provide lighting effects for display and display devices such as laminates and display cabinets. Laminates are usually made of transparent or translucent materials, such as glass, acrylic, etc., to display products or items.
Laminate lighting By installing lamps under or on the side of the laminate, the light shines directly onto the laminate, achieving the highlight of the display items and creating an attractive effect. Common lighting methods include:
Laminate backlight lighting: The light is installed behind the laminate, and through the transparency of the laminate, the item shows a bright and uniform effect under the illumination of the light. In this way, the display items can look more vivid and eye-catching.
Laminate sidelight lighting: The light is installed on the side of the laminate, so that the light comes in from the side, through the refraction and reflection of the laminate, evenly illuminating the display items. In this way, the texture and details of the item can be highlighted, enhancing its attractiveness.
Laminate point lighting: The use of small, high-brightness lamps to focus the light on a specific location to highlight the focus or specific part of the display item. This is often used to highlight a product or specific detail to create a unique visual effect.
Laminate lighting technology can be applied to various scenarios, such as shopping malls, museums, exhibitions, stores, etc., for displaying jewelry, watches, artwork, merchandise, and other items. It can not only enhance the ornamental and attractive of the display items but also improve the overall effect of the display environment and enhance the beauty and experience of the space.Laminate Lighting System,Laminate Backlight Lighting,Laminate Sidelight Lighting,Laminate Point Lighting,Laminate Lighting Technology
