The "Digital garden" project uses transparent projection, gesture interaction, and infrared sensing technology to present multiple different digital garden scenarios to the audience. In the central scene, when the audience stands in a specific area and makes gesture movements, they can interact with virtual natural plants. When the audience reaches out or makes specific actions, the infrared sensing technology captures the action signals, and the virtual plants will correspondingly produce dynamic changes such as growth and swaying, as if they really exist in front of the eyes. The transparent projection technology skillfully integrates the virtual plants with the real scene, creating an illusory visual effect. This project is applicable to various scenarios. Whether it is a creative display in a brand activity, a theme exhibition in a shopping mall atrium or an exhibition hall, or a leisure experience in an outdoor park, it allows the audience to deeply feel the charm of the integration of nature and technology, and stimulates people's love for nature and thinking about technological development.
