Description

Technical Field

[0001] The present application relates to the technical field of image control interaction, and in particular to a sundial device for controlling the change of four seasons scenes. Background Art

[0002] Most electronic control methods now rely on knobs, such as the knob device on the console to switch the four-season lighting projection changes of the entire scene, or rely on remote control methods of computers, or rely on various external electronic control devices. These methods are widely used in commercial places such as bars, immersive spaces, and game halls. Through the precise control of electronic equipment, highly customized lighting and projection effects are achieved, greatly improving the user experience and interactivity. However, these electronic control methods usually require complex hardware and software system support, which is costly and complex to maintain. In contrast, mechanical and physical rotating devices are simpler and more intuitive, suitable for exhibition hall explanation scenes, and use the half-hidden characteristics of rotation to attract tourists or visitors to rotate the device to present specific information or content.

[0003] Most of them use physical mechanical devices, relying on human-initiated rotation to provide power to present the content posted on the back. For example, a shaft with content printed on two or more sides, using the rotating shaft to continuously change the side to display the content on the top; or using the shaft and turntable to cover the display part of the content, and the content of the display part will change as the visitor turns. In addition, there is also a way to use a rotating disc to mark a mark on the middle screen display disc to point to the pre-stored picture or video corresponding to the text content. Although these methods are simple and easy to operate, their expression form is relatively single and lacks rich interactivity and fun.

[0004] Although existing mechanical rotating devices can attract users' attention, they have caused many tourists to feel sensory fatigue due to their diverse forms and frequent use. Moreover, due to the basically consistent effects, lack of fun and sustainability, users gradually lose interest, making these devices often only exist as decorations and unable to maintain their appeal for a long time. Specifically, these devices mainly rely on simple mechanical structures, lack dynamic changes and instant feedback, and cannot meet the needs of modern users for diversity and high interactivity. Therefore, there is room for improvement. Summary of the invention
